  • FFMPEG .mov to png sequence alpha issue

    19 décembre 2014, par user2491598

    I have a .mov file that has alpha background. I am trying to convert the movie to .png sequence and the alpha in each png is not correct. Here is an example of the png result I get
    enter image description here

    However, the image is supposed to look like this
    enter image description here

    The ffmpeg command I use is the following

    ffmpeg -i  out.mov -vcodec png out_%05d.png

    Any thoughts why am I getting bad alpha channel ?

  • ffmpeg, random video-clip(s) not ending at the specified -to [value]

    21 mars 2023, par query-01

    Windows 10 Home, Version : 22H2

    


    ffmpeg version 2021-11-10-git-44c65c6cc0-full_build-www.gyan.dev

    


    The Issue : Within the .bat below, I randomly experience a video-clip that will not truncate/end —at the value entered for -to . That said, if I have four files joined, then output to —> output.mp4, at least one file will not end at the specified -to [value], yet the other adjoining clips will have complied with their specified -to [value].

    


    All of the video-clips are processed by the original system and remain un_touched —until this .bat (below).

    


    What am I doing incorrectly, and/or, what should I be looking for within the affected video-clip, that would cause this behavior ?

    


    Setlocal EnableDelayedExpansion
::"C:\Program Files\Bulk Rename Utility\Bulk Rename Utility.exe" %CD%
for /F "delims=" %%i in ('dir /B /O *.mp4') do (
set f=%%i
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" "!f!"
set /p ss="Enter hh:mm:ss: "
set /p t="Enter Duration: "
ffmpeg -i "!f!" -ss !ss! -to !t!  -c:v copy -c:a aac _"!f!"

)

for /F "delims=" %%i in ('dir /B /O _*.mp4') do @echo file '%%i' >> clips.txt
set /p fn="Enter A Filename:"
ffmpeg -safe 0 -f concat -i clips.txt -c:v copy -c:a aac !fn!.mp4

)
