Howdy, my intention is to split a big video file into smaller chunks for more convenient storage and transfer.
At one point I figured that the total amount of space the chunks produced by ffmpeg are taking is smaller than the size of the original file. Then I noticed the above is true even if I just copy both streams from the start to the end into one file: ffmpeg -i Svalbard2016_g04033.mp4 -acodec copy -vcodec copy -map 0 output.mp4 Here, the output file I'm getting is 5MB smaller than the source file. And if I do the same for a bigger source file, the size difference is bigger as well. Any thoughts why this is happening? I'm going to delete the source files eventually, hence I'm afraid if I'm losing anything (metadata?) in the process. Source file: https://dl.dropboxusercontent.com/u/30369146/Svalbard2016_g04033.mp4 (produced with an original SJ5000+ camera, if that's of any help) Thanks in advance. -- Sincerely yours, Olexandr Melnyk http://omelnyk.net/ _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
