I've been using this tool to cut and add audio tracks to some of my video files. Occasionally, the output file is of the size I'd expect (100-300MB smaller if extracting an audio track), but the video track doesn't show at all. The file will play with audio and subtitles working; just not the video track itself. Am I missing a setting or something like that?"}}
