Forget what mediainfo I posted , I am a new user and I am asking for advice: How can I re-encode a video after changing it while keeping it as identical as possible?
I guess I need help evaluating the parameters for " identical" so I am consulting with you guys : I want to keep the timestamps , quality and the file-type Is there anything else I am forgetting ? -----Original Message----- From: ffmpeg-user [mailto:[email protected]] On Behalf Of Moritz Barsnick Sent: Monday, October 19, 2015 12:40 PM To: FFmpeg user discussions Subject: Re: [FFmpeg-user] Slicing a 4K video to images and then encoding them back using the same codec On Sun, Oct 18, 2015 at 11:46:34 +0000, Liran Sharoni wrote: > I don’t have 2 files, I have only 1 movie , and thats it.

Data rate and frame rate are also encoding parameters. Why do you want to keep as many parameters of the original video as possible? > If a suggestion like Kieran would work with "-vcodec copy" I'd be a > happy man , but this isn't the case , because I get an error ( for > applying a filter) Yes, that is a user error. You cannot change the contents of the video while copying, those are two totally different concepts. In other words: Copying a video stream implies _not_ changing it at all.
