How to concatenate two or more videos with same width and different height in FFMpeg and to maintain the same aspect ratio ?
25 octobre 2019, par AarwilI have five video parts to concat all. Each five videos are in the same width and height. The second part is the hstack of another 2 videos and the third part is the hstack and vstack of another 3 videos. While concat all the five video parts the aspect ratio is not maintaining in the final video. Since I am new to ffmpeg help me to sort out the problem
I have tried with the command in my final with filter complex and to reduce the size I used frame per second.
"ffmpeg -i
final.mp4 -vf scale=1280:480 -filter:v fps=fps=30 finalNew.mp4"but nothing worked.
Also help me to use hstack with scaling, to maintain the aspect ratio for the second part on below commandCommand : ffmpeg -i vid1.mkv -i vid2.mkv -filter_complex "[0:v]scale=-1:480[v0] ;[0:v][1:v]hstack=inputs=2"vid3.mkv

ffmpeg encoding for 3.0 and 3.1 channels in Dolby Digital format (.ac3)
4 novembre 2019, par CC2023I was able to encode .wav to .ac3 (Dolby Digital) via.zz ffmpeg for channel 2.0, 2.1, 4.0, 4.1, 5.0, 5.1, but not channel 3.0 and 3.1.
When I played back .ac3 files on Onkyo 7.2 receiver, error on channel 3.0 and 3.1 was :
3.0 channels :
right channel ok
left channel ok
center channel played back at subwoofer
3.1 channels :
right channel ok
left channel ok
lfe channel ok
center channel played back at surround left speaker (sL)
This is command I used :
ffmpeg -i 3_channel.wav -c:a ac3 3_channel.ac3
ffmpeg -i 3_1_channel.wav -c:a ac3 3_1_channel.ac3My ffmpeg version git-2019-10-28-68f623d
Why I have successful encoding on channel 2.x, 4.x, 5.x, but not 3.x ? thanks ahead for any comments.

Audio drift in Premiere (not VFR)
22 octobre 2019, par petaireI’m getting audio drift in Premiere, and it’s not related (or is it ?) to VFR. I honestly really dont know where this is coming from, but, oh God, Premiere… Obviously, when I read the file in VLC or any other player, it’s fine. But in Premiere…

I think it might be related to this line :
Frame rate : 46.875 fps (1024 SPF)
I’m using this line for ffmpeg encoding :
ffmpeg -err_detect ignore_err -i $1 -preset veryfast -strict -2 -c:v libx264 -vf scale=-1:720 -threads $numberOfThreads $2
Do you know how to force SPF to 25FPS (of the SPF equivalent) ?
