With that said, it supports most popular video formats like MP4, MOV. The video will not be an exact cut because of the keyframe offset. The program is actually powered by HTML5 and seems to be using the Chromium engine. If I want to cut losslessly I can add the additional ffmpeg parameter, or typically use it on the command line directly.įfmpeg -ss 1:30 -i in.mkv -c copy out.mkv (from the top of my head) would cut of the first 1min 30s, but losslessly. In this course, we will explore the features of the application by starting to look at how to set in and out points in the video to get it ready to export videos and individual cut files.
