  • Does 'keyint infinite' improve overall compression with crf and mb-tree ?

    23 avril 2012, par HitomiTenshi

    After reading what intra-refresh does, I kinda got confused. I'm encoding for YouTube and YouTube will re-encode the video-file anyways, so I thought "why not removing all these heavy IDR-frames ?" I just want to compress my video as hard as possible, enabling everything that could help me getting a lower filesize, but still maintaining a high quality.

    I used to test around stuff with lossless QP encoding, but the only thing I could max out was the merange. Here is a paste of my x264 settings : Pastebin.

    I want to achieve highest compression while maintaining visually lossless quality. (using crf values around 10 - 13, and merange 32)

    Could anyone give me advice on how to compress my video super hard (without touching the crf value !). I also want to know if it's true, that keyint infinite reduces overall compression.

  • Compress Recorded Video Faster [duplicate]

    2 novembre 2016, par Ali Hassan

    This question already has an answer here :

    I am recording video using media recorder. 10 Seconds recorded video size is 22MB. I am using FFmpeg to compress the video. Compressed video size is 2MB. This is fine. Problem is compression time that is around 40 seconds or more. I have been trying different solutions. I have looked this, this and this. I also tried changing bitrate, quality etc. But no success. Below is the command that I am using :

    ffmpeg -y -i /storage/emulated/0/myapp/testVideo.mp4 -strict experimental -vcodec libx264 -preset ultrafast -crf 24 -acodec aac -ar 44100 -ac 2 -b:a 96k -s 960x540 /storage/emulated/0/myapp/compressedTestVideo.mp4

    May be there is some other way to compress faster ? Is it possible to compress video while recording, if so, how ?

  • ffmpeg copy and discard missing or incomplete frames

    30 janvier 2017, par encore2097

    If theres a video file that is partially downloaded, how can you use ffmpeg to copy it and cut out all the incomplete and/or corrupt frames.

    Tried this :

    ffmpeg -err_detect ignore_err -i video.mkv -c copy video_fixed.mkv

    Source : http://video.stackexchange.com/questions/18220/fix-bad-files-and-streams-with-ffmpeg-so-vlc-and-other-players-would-not-crash

    but it simply copied the video missing / incomplete frames and all.
