  • Ffmpeg. Best way to rip dvd and convert mov into lossless mp4 that is playable in QuickTime on Mac ?

    19 octobre 2022, par Liam

    I’ve been ripping my collection of anime dvds with MakeMKV and converting them into .mp4 files using Ffmpeg.

    


    There are a couple things I need help with-
I’ve noticed that using the command ffmpeg -i input.mkv output.mp4 works in converting the mkv into a playable mp4 file in QuickTime player but that it has a smaller file size than the original MKV file.

    


    Does this indicate a loss in quality ?

    


    I’ve used another command
Ffmpeg -i input.mkv -c copy output.mp4

    


    to convert the MKV file into mp4 and the file is identical in size but will not play in QuickTime as the previous converted file did despite both being mp4.

    


    Does this mean that this mp4 file is just as recognisable as an mkv file ?

    


    I then did another command which may be the best as it plays in QuickTime but it resulted in by far the largest output file size.

    


    Ffmpeg -i input.mkv -crf 01 output.mp4

    


    The last command I used is almost the same as previous but doesn’t play in QuickTime for unknown reasons.

    


    Ffmpeg -i input.mkv -crf 00 output.mp4

    


    Results in huge file size and mp4 file which won’t play in QuickTime.

    


    Please can you shed some light on these issues and advise me on if these commands are best to use for lossless quality ?

    


    The Dvds and files are standard definition and animated in the 90s so that might be worth mentioning.

    


  • Ffmpeg can't convert at 24fps AND burn a subtitles

    14 novembre 2020, par Oshida_BCF

    i like to save my anime but i don't like when the subs are softburned and if the video is in mkv (it's heavier)

    


    so i made some .bat that encode the video and burn the subtitles.

    


    cd To convert
for %%a in ("*.mkv") do ffmpeg -i "%%a" -vf subtitles="%%a" -crf 18 -c:v libx264 -c:a aac -b:a 256k ../Converted/"%%~na.mp4"
pause


    


    this command burn the subtitles and it's perfect

    


    cd To convert
for %%a in ("*.mp4") do ffmpeg -i "%%a" -filter:v fps=fps=24 -crf 18 -c:v libx264 -c:a aac -b:a 256k ../Converted/"%%~na.mp4"
pause


    


    this one encode at 24 fps and it's perfect too

    


    but this one

    


    cd To convert
for %%a in ("*.mkv") do ffmpeg -i "%%a" -vf subtitles="%%a" -crf 18 -c:v libx264 -c:a aac -b:a 256k -filter:v fps=fps=24 ../Converted/"%%~na.mp4"
pause


    


    doesn't work.

    


    and i have no idea

    


    it convert the video in mp4, at 24fps
but it "forgot" the subtitles

    


    do there is some commands that aren't compatible and cancel each other ?

    


    for now i burn the sub on the video and i convert at 24 fps after.
but being able to do the 2 at the same time would save me a lot of time.
