But I don't know how to do this for FFmpeg. But I wanted to make this encoder by FFmpeg using a variable bitrate rate. I usualy did the encoder to get the out video with MEGUI. I did an avisynth script with improvements for the video. Just substitute your own timecodes.Īctually I have a video clip, it has an average of 5 minutes. (which I took from something I actually did) will work. My advice is to do tests, as I've already recommended, and to A/B between the original and h.264 or h.265 at a high bitrate.įfmpeg can cut videos losslessly, and if that is all you want to do then something like this:įfmpeg -i MAH05691.MP4 -ss 00:15:29.112 -c copy -t 00:07:14.250 Action_Cam_01.mp4 It would be silly not to do this, because uncompressed not only consumes massive amounts of storage, but can be difficult to play back without hiccups. You can use a 'lossless' compression to at least make the file size smaller. So, it makes zero sense to take such a source and store it as uncompressed. Unless you are in a studio and have the ability to capture uncompressed directly from the unaltered output of a professional video camera, your video source has already been compressed and will contain artifacts from that operation. The same statement applies to DVD, BD, streaming sources, etc.

Are they from a video camera? If so, they have already been massively compressed. Have you actually done any tests? I fully understand the quest for quality, but you may or may not be able to see the differences between various ways to encode a particular video, and you won't know for sure if you can see any differences until and unless you do your own tests.įirst of all, you don't mention the source of your videos.
