convert exr filesequence with ffmpeg and x264 [closed]
29 novembre 2012, par user1863947When i convert a exr sequence into quicktime mov file using ffmpeg and x264 codec it codes the video but in quicktime player and windows media player its just black ! but when i open it up with vlc i can see the image and it looks fine. When i try the same thing with a jpg sequence instead of exr it works perfect ! does anyone have an idea what that could be ?
here is my ffmpeg code :
ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.movHere is the console output :

FFmpeg overlay PNG after scaling has not necessary black borders
24 mars 2021, par Mikołaj HenklewskiI have two PNG files that I want to add to the video :


- 

- Two lines text
- Circle






but on the final video, they have black borders (they do not have it originally !) Actual Result.. The question is why FFmpeg is adding it on scale effect, and how to avoid adding it ? Command is :


ffmpeg -i 3d9678e2e58c4d08a24363468d0cfd3e.mp4 -i caption-1616544596077-d.png -i caption-1616544596080-d.png -filter_complex

[1_rot]scale=iw/2:ih/2[1_rot_scale];
[0:v][1_rot_scale]overlay=x=288:y=50:enable='between(t,0,3.2)':format=auto[1_out];
