LosslessCut: lossless video/audio editing
> This app is not for exact cutting. Start cut time will be "rounded" to the nearest previous keyframe, which may be a fraction of a second before your desired cut point, or up to several seconds, depending on the encoding.I found this problem with all ffmpeg-based editors...does anybody know of an editor capable of cutting between inter-frames? The same happens with sound files, which is inconvenient.
