  • 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 :

    There are only video streams, they look to be the same codecs/fps

    I am using this command to concatenate them :

    ffmpeg -f concat -i files.txt -c:v copy -y output.avi

    I don’t get any output from the terminal and it outputs a file.

    The file opens and the content in 1_tmp.avi plays fine, at the same quality, but when it gets to the point in the video where 2_tmp.avi should be, it’s pixelated static all the way through (see image below).

    static screen for second file after concatentation - mama **did not** say there would be days like this.

    If I use a command like :

    ffmpeg -i 1_tmp.avi -i 2_tmp.avi -filter_complex "[0:0] [1:0] concat=n=2:v=1 [v]" -map "[v]" output.avi

    I do get full output of both videos merged together, but it is dropped to an mpeg codec and the quality loss is noticeably prominent.
