hi I am using ffmpeg xfade to concat two clips, the transition looks fine, but the second clip has no audio in the output. I don't find more information about this in https://trac.ffmpeg.org/wiki/Xfade and the official doc. Can I keep the audio of both clips in sync?
I'm puttting the complete log below, it's massive
ffmpeg -i teacher1.mp4 -i teacher2.mp4 -filter_complex xfade=transition=fadewhite:duration=1:offset=14.5 output.mp4

I tried to combine mp4 format video and wav format audio.
The video is shorter than the audio and start second is same as 00:00.
I used command as bellows:
ffmpeg -i video.mp4 -i audio.wav -filter_complex "[0:a]volume=0.2[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y -shortest output_video.mp4
The problem is the output_video.mp4 is a silent video without the sound.
How can I get the output_video.mp4 with sound from audio.wav?
ffmpeg output is:

There's no need to mess about with filter_complex, you are not changing anything. You simply want to map the video from one source to the audio from another.
ffmpeg -i input.mp4 -i input.wav -shortest -map 0:v -map 1:a out.mp4
should achieve what you require.
Using ffmpeg I add a video overlay successfully over an origin video (origin has audio, overlay doesn't). However the audio of the origin video doesn't appear in the result video.
ffmpeg -i source.mp4 -i overlay.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, scale=1280x720[top];
[1:v]setpts=PTS-STARTPTS, scale=1280x720, format=yuva420p,
colorchannelmixer=aa=0.2[bottom]; [top][bottom]overlay=shortest=1"
-shortest -acodec copy -vcodec libx264 result1.mp4
Even if I execute the following separate command on the result of the previous command - still no audio appears in the new result video.
ffmpeg -i result1.mp4 -i audio.mp3 -c:v copy -c:a aac result2.mp4

Tell it which audio you want with -map:
ffmpeg -i source.mp4 -i overlay.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, scale=1280x720[top];
[1:v]setpts=PTS-STARTPTS, scale=1280x720, format=yuva420p,
colorchannelmixer=aa=0.2[bottom]; [top][bottom]overlay=shortest=1[v]"
-map "[v]" -map 0:a -shortest -acodec copy -vcodec libx264 result1.mp4
See FFmpeg Wiki: Map.
Your original command did not use -map so automatic stream selection was enabled. This will choose the stream with the most channels which was the audio from overlay.mp4 (Stream #1:1).
I'm having trouble using xfade together with acrossfade.
I have two videos t1.mp4 and t2.mp4 of same fps, resolution and so on. Both videos are 15 seconds long.
Now I want a one-second fade transition in between.
Without acrossfade,
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p" output.mp4
after checking all the frames, the transition looks good. There are some overlapped frames with fading effect.
Please see below two consecutive frames.
But the second part of the result has no audio, that's why I decide to use acrossfade.
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4
Now it seems the transition effect is incomplete, there are less overlapped frames with fading effect, and the transition is sharp. Please see below two consecutive frames, same frame nubmer as above.
What am I missing here please?
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4

fixed by separating the video and audio track.
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "[0:v][1:v]xfade=transition=fadeblack:duration=1.000:offset=8.960,format=yuv420p[video];[0:a][1:a]acrossfade=d=1.000:c1=tri:c2=tri[audio]" -map [video] -map [audio] -movflags +faststart output.mp4
There is an open bug report for a similar issue that I've stumbled upon, in which separating video and audio does not solve the problem.
Here, the only reliable workaround was to process the audio completely separately from the video, in another ffmpeg command, and later merge it via stream-copying, e.g.:
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "[0:v][1:v]xfade=transition=fadeblack:duration=1.000:offset=8.960,format=yuv420p[video]" -an video.mp4
ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "[0:a][1:a]acrossfade=d=1.000:c1=tri:c2=tri[audio]" -vn audio.m4a
ffmpeg -i video.mp4 -i audio.m4a -c copy -movflags +faststart output.mp4
So have have the following FFmpeg command
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4
When the input files are played separately their audio is played equally through both headphones.
But after being merged the audio from the video is on the right side and the audio from the webm file is on the left side.
I see this in the output when I run the cmd
[Parsed_amerge_2 # 0x7fa0faf01bc0] No channel layout for input 1
[Parsed_amerge_2 # 0x7fa0faf01bc0] Input channel layouts overlap: output layout will be determined by the number of distinct input channels
How can I adjust this so that the output file has the audio from both the inputs in equally in the left and right sides?
Also is there a generic way to do this such that even different configurations (video has stereo and audio has mono ... or both have stereo) result in the Audio being split evenly.
I tried using the pan filter but there is something I am not understanding about how it works because either nothing happens or I flip left and right. But I am not getting even stereo.
fwiw here is the full output.
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4

Use amix instead of amerge and resample to stereo using -ac 2. Since you're mapping the first video, tell amix to terminate with first input.
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2[A];[A][1:a]amix=inputs=2:duration=first[Aout]" -map 0:v -map [Aout] -y mergeab.mp4
I'm trying overlay audio onto a video. I have a very simple ffmpeg command (auido.mp3 is much longer than the video)
ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map 0:v -map [a] test.mp4
This produces a silent video. However, when not mapping the video stream
ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map [a] test.mp4
The resulting audio file is as expected.
What could be causing this issues?
(Is there a better way to overlay audio onto a video via ffmpeg?)
