Try to set the start-cutpoint a few frames before or after the nearest keyframe (may also solve audio sync issues).However it is very experimental and may not work for most files. You may try to enable the new “Smart cut” mode to remedy this inaccuracy.If you’re seeing a blank video at the beginning of the resulting file, try Keyframe cut instead.Keyframe cut means -ss before -i and Normal cut means -ss after -i. ffmpeg also has documentation about these two seek/cut modes. You may need to try both, depending on the video. Your mileage may vary when it comes to Keyframe cut vs Normal cut.

For others, you may need to trial and error depending on the codec, keyframes etc to get the best cut. Lossless cutting is not an exact science.This means that you often have move the start cut time to few frames after the desired keyframe. Start cut time will be “rounded” to the nearest previous keyframe. Try the same operation with a different file (same codec or different codec) and see whether it’s a problem with just one particular file.Try to enable the Experimental Flag under Settings.Select a different output format ( matroska and mov support a lot of codecs.).Sometimes LosslessCut (ffmpeg) is unable to cut certain tracks at all. video) and if that succeeds, then work your way by enabling more tracks and see which one is causing the problem. First try to disable all tracks except the main track (e.g. Disable unnecessary tracks from the Tracks panel.Try both Keyframe cut vs Normal cut (do not use Smart Cut if you have any problem).If the video exports successfully without any error from LosslessCut, but it does not look as expected when playing back, please try this: Common / known issues & troubleshooting The exported video has a problem Apple App Store apps run in a sandbox, and therefore need to prompt for output directory before allowing writing files. They have exactly the same in-app features, except for a few platform limitations: Apple doesn’t allow opening VOB files with App Store apps. Then, once I’m sure that the new version works well, I will release it in the App Stores as well to give a frictionless as possible experience for customers. I consider the newest GitHub versions to be a public “beta” test. The GitHub version will contain new, untested features and may contain some bugs (even in existing functionality). LosslessCut version in the App Stores is often a few versions behind the latest GitHub version, because I want to be sure that the new versions work perfectly before releasing in the App Stores. Enable “advanced view” and then click the Yin Yang symbol.
