  • How to convert from .srt to .ass with FFmpeg without decoding errors

    10 avril 2020, par symonxd

    When I try the following command with FFmpeg (v. git-2020-03-24-e5d25d1) : ffmpeg -i subs.srt subs.ass, I get a bunch of the following errors :

    



    [srt @ 0000028ea78fa780] Invalid UTF-8 in decoded subtitles text; maybe missing -sub_charenc option
Error while decoding stream #0:0: Invalid data found when processing input


    



    and :

    



    [ass @ 0000028ea78ffe40] ReadOrder gap found between 3 and 4


    



    I found that my .srt file contains the following char : ë
I tried adding the flag -sub_charenc UTF-8 as stated here with no success.

    



    How can I successfully convert .srt to .ass ?

  • FFmpeg psycho-visual options - psy-rdoq

    7 avril 2020, par SLVR

    I'm new to encoding and I like to do my encodings in x265 10bit. Currently, I'm facing a little issue with ffmpeg. I noticed when I'm using libx265 encoder output file looks a little bit blurred or small detail loss. Code I used to do my encodes is

    



    ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -c:a copy -y output-x26510bit.mkv


    



    I've found out psycho-visual options might help in this case. I modified my code in to

    



    ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq 4 --rdoq-level 1 -c:a copy -y output-x26510bit.mkv


    



    When I issue the above command, I get an error code

    



    C:\Users\abc\Desktop\1>ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq
