Re-encode or Transcode - Compress in One Click


Convert to reduce the video file size. Support videos from everywhere, like GoPro, DJI, 4K camcorders, screen records, and so on. Meet the video upload requirement for Email, YouTube, TikTok, Instagram, Zoom, Discord, Whatsapp, LINE, Snapchat, Dropbox, etc. Prevent quality degradation caused by auto-compressing of the video platform.

Re-encode MKV/MP4/AVI/MOV Videos

Re-encode a video in one click to get smaller file size. Just input your video, and click RUN to output the file without making any settings. VideoProc will compress the video for you with the advanced compression algorithm. For example, you can reduce the file size without changing the original H264 codec, which is compatible with more video apps and platforms.

Transcode to Highly Compressed HEVC

HEVC/H.265 is known for high coding efficiency and great compression ability. As a successor to AVC/H.264, HEVC offers better data compression at the same video quality. According to our test, converting H.264 to HEVC in VideoProc Converter can save about 90% file size without a perceptible change.

Increase GOP Length - No Perceptibly Quality Loss

Best for Low-motion Videos, Also Optimized for High-motion Videos

A much longer GOP length will compress a video more efficiently, especially for low-motion or more static videos with little frame changes. Increasing the GOP length can provide higher video quality at lower bitrates. But if your footage is shot at high frame rates, high speed, or has complex subject, you can also try to adjust the GOP length slightly to get a smaller file size.

You can adjust the GOP length value in VideoProc Converter to get up to 90% small file size.
Import a video -> choose an output format -> go to Option -> find GOP and set the value:
  • For low-motion video: set the GOP value between 90 and 250 generally (depending on the original video).
  • For sports or high-motion video: set the GOP value to 30-60 generally (depending on the original video).
  • For further editing: set the GOP value to 30 generally.

Useful for Any Video

The following methods will apply to any video, such as vlogs, screen records, interviews, unboxing, and sports video. Any method can reduce the burden of your system, player, or editing programs, and avoid the lagging, buffering, and stuttering problems.

  1. 3. Lower frame rate: e.g., change 40fps to 20fps without visible quality loss.
  2. 4. Reduce bitrate: The most obvious compression to make a file smaller, but it's lossy.
  3. 5. Downscale resolution: Convert 4K to 1080p, 1080p to 720p for more efficient video uploading.
  4. 6. Adjust audio: Lower sample rates and bitrates, or remove the audio track if necessary.

Tips If you are not satisfied with the quality of a video compressed in an editing application, you can try exporting the edited file in an intermediate code and then compressing it with VideoProc Converter.

Make Video Smaller

Cut off Unwanted Clips
Cut and remove the unusable segments in a video. Shorten the video to reduce the final file size while keeping the original video/audio quality.
Split Long Video into Pieces
Many UGC sites have restrictions on the uploaded file length. If your video is long, you can split it into parts to export and upload them separately.
Crop and Resize
Crop the frame size of a video to remove an unwanted area to save size. You can keep the original aspect ratio or resize the video image to fit a different screen or platform.
Convert 4K to 1080p/2K
4K is a big workload for computing, editing, and uploading. Compressing 4K to 2K/1080p/720p will reduce the file size greatly. The quality is fine if played back on a smaller screen.
Video to GIF
Adding a GIF instead of a video as an attachment is friendly for Email sending. Changing your video into an animated GIF will reduce the file size while making it fun.

Fix Video Playback Issues

Resolution Too High
High resolution, esp. 4K is power consumption. Only the latest hardware with faster write speeds can handle high-quality videos and modern formats. Lowering the resolution can make your high-resolution videos playable on any device without stutters.
Frame Rate Too High
There is an upper limit on the frame rate that a mobile phone or other device can support for playing a video. A 4K 120fps video, for example, needs extremely high decoding and playing ability. If you want to play a high-fps video on a low-end device, you should reduce the frame rate.
