The majority of the proffesional video compressors are hard to learn. Therefore when picking up the right one, you should also look into whether it has presets and is easy to use or not on aside of comprasion rate and process speed. Here's what I found when using the presets of the best 3 proffesional video compressors to reduce the test video clips.

#VideoProc

Frankly speaking, VideoProc is currently the best video compressor for both Windows and Mac users. The beginner-friendly interface and useful presets allows you to compress video in an extremely easy manner, and then play or share on all popular devices and social media platforms.

Basically, you just have to drag and drop one or multiple large videos into the tool above, this No.1 video compressor can shrink the video file over 90% of its original size.

#HandBrake

If you've used HandBrake, then you've undoubtedly heard about how jampacked this cross-platform video compressor is. Based on FFmpeg, HandBrake enables you to compress video from all popular codecs including MP4, AVI, MOV, H.264, and HEVC, etc. It offers you full control over video parameters, and that sounds nice.

However, beginners are always advised to stick with HandBrake preset options. Why? You'll have to climb a steep learning curve before you can apply customized settings on a video to shrink its size without A/V out of sync problems, missing audio, or other errors.

#Freemake Video Converter

Freemake Video Converter used to be my favorite video compressor. However, it hasn't received any update since 2017. Thus, many new but important features are missing in this phased-out video comprssion software. Here I take some examples. H.265 and VP9 are not supported by Freemake Video Converter. This Windows-only video compressor provides us some presets, but only matches with iPhone 5, iPhone 4, and things before 2017. As for the compression ratio, it left far behind VideoProc and Handbrake.

(The testing videos come with length from 1:30 minutes to 3 minutes) Everytime, Freemake Video Converter got stuck when finished the process of 60% to 85%.

Media Players that Can Compress Video: VLC media player, QuickTime Player

They retain the popularity of the compression software market for a long time due to the high availability and reliability. We all have at least one media player on our computer, right? The common drawbacks of these tools are slow response speed, limited output format options, and the lack of a custom control on video parameters.

Therefore, when selecting a video player to compress your video, you should at least figure out: what video and audio formats it can process and generate. Can you define a specific value for the resolution, bitrate, and other parameters of a compressed video? Or it only lets you to choose among several levels (high, low, etc.) of quality?

It's hard to compare the compression capability of two media players as the available output video codecs, resolution and other options differ a lot, as like, VLC media player allows you to customize everything, but QuickTime only allows you to shrink video size by changing resolution. Anyway, I applied the ready-made setting of each media players to compress videos:

In VLC media player, I selected HEVC + MP3 as the output file.
In QuickTime Player, I chose Save as 1080P video.
And here's what I've found.

Unbeknownst to some, the VLC media player is a cross-platform and multiple media player on Mac, Windows, and Linux that does more than playing videos and music. It can also serve as robust video compression software for shrinking the size of your MP4, AVI, MKV, and MOV videos. On the plus side, this full-featured tool provides you with the ready-make options, as like H.265+ MP3, H.264 +AAC, and you're on your own to decide the desired video codec, audio codec, frame rate, bitrate, and other properties.

However, the compressed videos sometimes have A/V out-of-sync and black screen issues. Too many important features are hidden in the menu, making it one of the most sophisticated video compressor.

Highlight Features:

• A wide range of input formats.
• Lower CPU usage rate when comparing with Handbrake.

Downsides:

• Slow compression speed.
• Difficult jargons.

Rating: ⭐⭐⭐

VLC media player's capability to compress large videos surprised me a bit of. It takes averagely 70% of my CPU usage to compress the H.264 video to HEVC file. Yes, it definitely falls behind VideoProc that takes only 0.5% computer resources. However, it does surpass Handbrake video compressor with 20% of saving in CPU resource, in this case.

#QuickTime Player

QuickTime Player isn't a typical video compressor software, but it still gets the job when you simply need to reduce the size of your video and not care so much on the quality, this easy MP4 compressor from Apple Inc. can get the job done perfectly.

Free Video Editing Software that Can Work as a Video Compressor

Most video editors meet the basic video compressing requirements. But, I don't advise occasional users who don't know the basic knowledge of the codec tech to compress videos with a video editor. A small mistake made by you might lead to extremely large output content and high computer resource usage. When choosing a video compressor from video editing software, check out what formats it support to compress and generate, and is there any explanation for each specification.

And below is what I found:

#Shotcut

In the experienced hands, Shotcut can be used to make some serious video compression work. In addition to the impressive features in editing videos, it supports nearly every major video and audio codec and has a great compression ratio. Almost everything you can do about compressing a video with a serious video compressor can get accomplished in Shotcut, though very possibly in a memory consuming and cumbersome way.

It does provide you with the Preset tab when exporting the video, however, it juts lists up the supported codec, as like, HEVC main profile and H.264 baseline, with little attempt to explain the jargon.

#iMovie

iMovie is the go-to choice for macOS and iOS users to make simple edits. It doesn't come with the compression command, and you can't customize the video parameters. The good thing is, though it doesn't let you dig into settings much further, iMovie allows you to assign different quality grades to your video when exporting. To put plainly, you can throw up a video to iMovie, skip the editing steps, and pick up a relatively lower resolution, bitrate, and quality grade to get the job done. Like most of other Apple software, iMovie has poor compatibility. It cannot compress MKV videos and many relatively rare video formats.

Highlight Features:

• Allow you to trim, cut, and crop to compress video.
• Estimate the final compressed file size and length.

Downsides:

• Take over 90% of the CPU resource.
• A high compression ratio always brings visible quality loss.
• Not support to customize the parameters for video compression.

Rating:⭐⭐⭐

iMovie is limited in comparison to most other Windows and Mac video compressors covered in this post. But for the overall performance, iMovie is stable and fast.

#Windows Movie Maker

I have to be honest here, Windows Movie Maker is known to have limited capabilities regardless you are using it as a video editing software or a video compression software. It can't compress AV1, VP8/VP9, HEVC, and many trendy video format. Whether you feed in the MKV, AVI, MOV, or other files, you'll get H.264 MP4 or WMV file after compression.

Regardless, I felt the need to mention it on this list because it is pre-installed to every Windows 7 computer and used to be one of the most popular and convenient MP4 compressor software for free. You'll be able to take the advantages of GPU acceleration tech to speed up the video compression process.

Highlight Features:

• Support hardware acceleration.
• Free and easy to use.
• Allow basic video editing.

Online Video Compressor

Online video compressor rises in recent years in response to the needs of compressing videos from your browser without having to install third-party software. However, I have to admit, they are very limited for serious video compression work. The fact is online compressors should be the last thing you want to consider.

They have a high reliance on your network environment, and the majority of them only allow you to get an output of MP4 files. The strict limits on video size and quantities are also biggies. If you are not put off by these limitations and stick on using an online video compressor, tools that accept a larger video and go compatible with a raft of video formats are always better to go.

Let's get straight to the testing result.

#Freeconvert

For those of you wishing to compress videos without installing extra video comprssor software, Freeconvert is for you. This web-based video compression software enables you to compress MP4, AVI, MKV, and other video files from your local drive, dropbox, google drive, or video URL to MP4, FLV, MKV, AVI, MOV, and 3GP file. It lets you compress a video by adjusting the size, changing the Max bitrate, or tuning the picture quality. For instance, the source file is 100 MB, when you choose Compress video by size, and set up Reduce the file size by 50%, theoretically, you'll make it shrank to 50MB.

However, Freeconvert doesn't guarantee you a smaller result. When I added up a 26MB MP4 H.264 file to the Freeconvert video compressor, and choose to reduce the size by 1%, I finally got a 36MB compressed file which was bigger than the source. Another slightly vexing issue is the free Freeconvert video compressor doesn't allow you to compress video with a size larger than 1GB.

Highlight Features:

• Allow you to compress the majority of videos.
• Compress video by size, bitrate, or quality.
• Utterly easy to use.

Downsides:

• The compression speed totally depends on your network environment.
• No for compressing large videos.
• Only support the HEVC and H.264 encoder.
• Might enlarge your source video file.
• Pop-up ads.

Rating:⭐⭐⭐⭐

If I have to choose one online video compressor, Freeconvert will be my option. Freeconvert video compressor is more generous than the majority of online video compression software. The largest video file you can compress with it is up to 1GB. Better yet, it's completely free.

#OnlineConverter

OnlineConverter video compressor is the epitome of simple. Once you import a video to this online video compression software, you can enter the desired file size, and then hit Compress. That's it. The drawback? It doesn't leave you any room to customize the basic video parameters. The supported video size is 200MB at maximum. While OnlineConverter video compressor allows compressing MP4, AVI, FLV, MOV, 3GP, MKV, WMV, and many other videos, it accepts the output of MP4 video only. Thus means, everything will turn to MP4 video after compression. Mac os x lion software.

• Free compress video files right from your browser.

Downsides:

Rating:⭐

Personally I don't like it's 80-style interface. And I don't know about you, but what's the purpose of a compression software that doesn't support to compress large video at all?

MP4Compress.

MP4Compress is a web-based MP4 compressor that attempts to help you compress MP4 files without losing quality. Compared to all the nominated video compressors in this list, MP4Compress is perhaps the easiest option.

To use it, all things you have to do is importing a video and hitting Upload Video File. As you might already expect, this MP4 compressor doesn't offer you options to select the compression ratio, bitrate, resolution, or other properties for your purpose. Suppose you are not satisfied with the compressed video file quality or size, you have to change to another compression software, and restart the whole process.

However, don't worry too much. In most cases, it should satisfy your demand. I tested the compression capability of MP4Compress with some MP4 videos, and most of them were reduced to 40% ~ 60% of their original size.

Highlight Features:

• One-click to compress videos.
• Free to use without pop-up ads.
• Good compression ratio.

Downsides:

• Not allow to set up a more optimal compression ratio or picture quality.
• As an MP4 compressor, it won't work to compress MKV, AVI, MOV…

Rating:⭐⭐⭐

No ads, and not require registration to use. MP4compressor works like many online picture compressor, limited but efficient.

6 Compression Tech that You Should Understand

1. Convert to Another Codec with Higher Compression Efficiency.

The higher the compression efficiency refers to a smaller size. H.264 is currently is the most compatible video format, and we can figure out it has a better compression ratio than MPEG4/MPEG2 and H.263.

Suppose you are holding an 800MB of MPEG 4 video, then compressing it to an MPEG4 clip will save you 300 to 400MB of storage space. What if you want to compress an H.264 or VP8 videos? Any better choice when you simply want to squeeze the size of your video without having to consider its compatibility?

Transcode your video to HEVC, VP9, or AV1. According to Netflix's test made upon 5000 12 seconds clips, VP9 and HEVC are capable of compressing the video size by 50% while still achieving the same high quality to H.264 and VP8. AV1 has a similar high compression ratio than HEVC. Suppose the source file is in H.264, a compressor that supports HEVC codec will help you reduce the file size by half or more without sacrificing quality.

The best video compressor that lets you make the transcode is VideoProc. This fancy video compression software can compress any video to HEVC, VP9, AV1 and other advanved codec. Meanwhile, it always keeps itself updated with the latest high entropy codec algorithm for offering you the best compression effecieny and lossless quality. The support of re-encode is another big plus of VideoProc as it lets you reduce the original file size by 80% or even more without making any adjustments on video codec or other parameters.

News: Reported by BBC, the new VVC codec could save 27% and 35% on video size than HEVC. Thus, very possibly, VVC is the future best target format when compressing video.

2. Lower the Bit Rate.

Best examples of a video compressor that allows you to define the bitrate: VideoProc, Handbrake, Shotcut.

The video bitrate in Mb (Megabits) is the amount of the bits that are processed in a second. When other parameters of the video are the same, a higher bit rate equals a larger size and a higher quality. For instance, an uncompressed 2minutes, 23.976fps, 1920x1080P, 35Mbps video takes storage space of 518.4MBs. The same clip of video with a bitrate of 12Mbps costs you only 172.8Mpbs of storage space.

• Only allow you to export video(s) in MKV, WebM, and MP4 format.
• Too difficult to master if you are a first time user.
• Slow compression speed and high CPU usage.

They have a high reliance on your network environment, and the majority of them only allow you to get an output of MP4 files. The strict limits on video size and quantities are also biggies. If you are not put off by these limitations and stick on using an online video compressor, tools that accept a larger video and go compatible with a raft of video formats are always better to go.

Let's get straight to the testing result.

#Freeconvert

For those of you wishing to compress videos without installing extra video comprssor software, Freeconvert is for you. This web-based video compression software enables you to compress MP4, AVI, MKV, and other video files from your local drive, dropbox, google drive, or video URL to MP4, FLV, MKV, AVI, MOV, and 3GP file. It lets you compress a video by adjusting the size, changing the Max bitrate, or tuning the picture quality. For instance, the source file is 100 MB, when you choose Compress video by size, and set up Reduce the file size by 50%, theoretically, you'll make it shrank to 50MB.

However, Freeconvert doesn't guarantee you a smaller result. When I added up a 26MB MP4 H.264 file to the Freeconvert video compressor, and choose to reduce the size by 1%, I finally got a 36MB compressed file which was bigger than the source. Another slightly vexing issue is the free Freeconvert video compressor doesn't allow you to compress video with a size larger than 1GB.

Highlight Features:

• Allow you to compress the majority of videos.
• Compress video by size, bitrate, or quality.
• Utterly easy to use.

Downsides:

• The compression speed totally depends on your network environment.
• No for compressing large videos.
• Only support the HEVC and H.264 encoder.
• Might enlarge your source video file.
• Pop-up ads.

Rating:⭐⭐⭐⭐

If I have to choose one online video compressor, Freeconvert will be my option. Freeconvert video compressor is more generous than the majority of online video compression software. The largest video file you can compress with it is up to 1GB. Better yet, it's completely free.

#OnlineConverter

OnlineConverter video compressor is the epitome of simple. Once you import a video to this online video compression software, you can enter the desired file size, and then hit Compress. That's it. The drawback? It doesn't leave you any room to customize the basic video parameters. The supported video size is 200MB at maximum. While OnlineConverter video compressor allows compressing MP4, AVI, FLV, MOV, 3GP, MKV, WMV, and many other videos, it accepts the output of MP4 video only. Thus means, everything will turn to MP4 video after compression. Mac os x lion software.

Personally I don't like it's 80-style interface. And I don't know about you, but what's the purpose of a compression software that doesn't support to compress large video at all?

MP4Compress.

MP4Compress is a web-based MP4 compressor that attempts to help you compress MP4 files without losing quality. Compared to all the nominated video compressors in this list, MP4Compress is perhaps the easiest option.

To use it, all things you have to do is importing a video and hitting Upload Video File. As you might already expect, this MP4 compressor doesn't offer you options to select the compression ratio, bitrate, resolution, or other properties for your purpose. Suppose you are not satisfied with the compressed video file quality or size, you have to change to another compression software, and restart the whole process.

However, don't worry too much. In most cases, it should satisfy your demand. I tested the compression capability of MP4Compress with some MP4 videos, and most of them were reduced to 40% ~ 60% of their original size.

Highlight Features:

• One-click to compress videos.
• Free to use without pop-up ads.
• Good compression ratio.

Downsides:

• Not allow to set up a more optimal compression ratio or picture quality.
• As an MP4 compressor, it won't work to compress MKV, AVI, MOV…

No ads, and not require registration to use. MP4compressor works like many online picture compressor, limited but efficient.

6 Compression Tech that You Should Understand

1. Convert to Another Codec with Higher Compression Efficiency.

The higher the compression efficiency refers to a smaller size. H.264 is currently is the most compatible video format, and we can figure out it has a better compression ratio than MPEG4/MPEG2 and H.263.

Suppose you are holding an 800MB of MPEG 4 video, then compressing it to an MPEG4 clip will save you 300 to 400MB of storage space. What if you want to compress an H.264 or VP8 videos? Any better choice when you simply want to squeeze the size of your video without having to consider its compatibility?

Transcode your video to HEVC, VP9, or AV1. According to Netflix's test made upon 5000 12 seconds clips, VP9 and HEVC are capable of compressing the video size by 50% while still achieving the same high quality to H.264 and VP8. AV1 has a similar high compression ratio than HEVC. Suppose the source file is in H.264, a compressor that supports HEVC codec will help you reduce the file size by half or more without sacrificing quality.

The best video compressor that lets you make the transcode is VideoProc. This fancy video compression software can compress any video to HEVC, VP9, AV1 and other advanved codec. Meanwhile, it always keeps itself updated with the latest high entropy codec algorithm for offering you the best compression effecieny and lossless quality. The support of re-encode is another big plus of VideoProc as it lets you reduce the original file size by 80% or even more without making any adjustments on video codec or other parameters.

News: Reported by BBC, the new VVC codec could save 27% and 35% on video size than HEVC. Thus, very possibly, VVC is the future best target format when compressing video.

2. Lower the Bit Rate.

Best examples of a video compressor that allows you to define the bitrate: VideoProc, Handbrake, Shotcut.

The video bitrate in Mb (Megabits) is the amount of the bits that are processed in a second. When other parameters of the video are the same, a higher bit rate equals a larger size and a higher quality. For instance, an uncompressed 2minutes, 23.976fps, 1920x1080P, 35Mbps video takes storage space of 518.4MBs. The same clip of video with a bitrate of 12Mbps costs you only 172.8Mpbs of storage space.

The good part is, the large consumption in space doesn't trade you with the same grade of optimization in visual experience. It's very difficult for our eyes to notice the difference between a 12Mbps and a 35Mbps HD video. Below is the recommended video bitrate for video in different resolutions that you can take a reference.

3. Downgrade the Resolutions

The best video compressor that allows you to downgrade the resolution without losing quality: VideoProc.

A video with a higher resolution gets more pixels to show the details of the picture, and that is why people now like 4K UHD and 1080P videos. However, it's hard for our eyes to notice the difference when you are watching a 1080P video or 720P video on a smartphone, so is the same when watching 4K videos and 1080P videos on an HD TV or computer. Thus you can simply downgrade the resolution from 4K to 1080P and 720P, or shrink 1080P to 720P to compress the video. From our test, VideoProc is the best compassion program as it has fast response and retains over 99% of the original quality.

4. Reduce the Frame Rate

Handbrake software alternative. The easiest video compressor that allows you to reduce the frame rate: Freemake Video Converter, VideoProc.

The high frame rate can bring you a true-to-life and smooth viewing experience when watching sports shows, video games, action movies, and other videos with fast motion content. However, suppose your videos are about landscapes, yoga courses, photo slideshows, and other relatively static images, turn to a low frame rate is a nice idea. When the given other parameters are the same, here's the difference in file size:

5. Increase the Value of GOP

What video compressor can reduce the file size by increasing GOP value: VideoProc, HandBrake, Shotcut.

GOP, also known as a group of pictures, is comprised of one I-frame, and many P- and B-frame. I-frame remains all data of a frame P and B frame in a GOP is predicted by I-frame. P-frame covers the differences between it and the previous I frame. B frame contains the difference between the adjacent two I-frame. The length of the GOP refers to the number of frames between two I-frames.

When one increases the length of GOP length, the number of I-frame decreases and the video gets to be compressed. If your video contains few motions changes, just feel no hesitate to apply a video compressor to enlarge its GOP length.

6. Remove the Audio Track

The fastest video compressor can shrink your video by removing the audio track in one click: VideoProc.

This sounds a weird method. But it definitely makes sense, especially when you compress a video for sharing on social media like Facebook, Linkedin, Twitter, and Instagram as 80% of people in those platforms now watch videos in mute. And you know what? 2 minutes of 32bit, 384 KHz, WAV video might come with a size larger than 350Mbs. So why not simply remove the sound from your video file.

Why Should We Compress DVD

Free Video Compression Software
