  • FFMPEG-jpg sequence to H.264 generate best result

    18 octobre 2015, par Ziki

    I have a jpg sequence which I need to convert to mp4, and I need to get the best result.

    As I understood, I need to supply the ’ffmpeg’ cmdln the following : bitrate, minrate, maxrate and bufsize.

    The only thing that I found about calculating the above params, is if I have the final output file size. But considering I want the best quality, I don’t know the final output file size, and I don’t care what it will be.

    Of course I have the framerate and the total frames.

    Here’s my ffmpeg cmdln :

    ffmpeg 
    
-r 24 
    
-start_number 0 
    
-i "C:\pathToSequence\%06d.jpg" 
    
-c copy 
    
-vframes 792 
    
-threads 16 
    
-pix_fmt yuv420p 
    
-c:v libx264 
    
"C:\pathToOutput\result.mp4"

    The total size of the sequence is 128MB, 792 frames, 24 framerate, resolution 1280x720.

    Until now I used to add the following to the ffmpeg cmdln :

    -b:v 10000k -minrate 10000k -maxrate 10000k -bufsize 10000k

    And if it was 1080p :

    -b:v 20000k -minrate 20000k -maxrate 20000k -bufsize 20000k

    And I figured that if I put the max value that ffmpeg can handle (2147480) it will generate almost the same result as the above. But I think it’s a bad approach(correct me if I’m wrong).

    So if I need to get the best result, how do I calculate it(or I can simply put the max value) ?

    Also I would like if you have another helpful flags to add to make the best final result.

    —EDIT—

    Here’s the updated command :

    O:\tools\ffmpeg -framerate 24 -start_number 0 -i "C:\share\localProcess\test\%05d.jpg" -vframes 54 -pix_fmt yuv420p -c:v libx264 -preset veryslow -qp 1 "C:\share\localProcess\result\result.mp4"

    And this is the ouptout :

    Mon test
    1) spip 3.1 svn 22109
    2) pas de plugins/auto mais le flux déclaré
    3) plugin tickets mis manuellement dans plugins
    4) j’active le plugin. Il se "préactive" en entendance les dépendances
    5) lorsque j’installe saisies, le plugin tickets peut bien s’activer
    6) mais les tables n’ont pas été installées
