Hi all,
I have a few questions about making timelapse videos from many pictures.
The following command makes a video with framerate 25 and works as expected:
ffmpeg -framerate 25 -start_number 123 -i IMG_%4d.jpg -codec:v mpeg4
output.mp4
My questions:

Please provide the sample, either use

or our ftp server (no limit), see:

If you use examples, you also need to understand them (or understand
what the original author was trying to do).

Hi,
I have a video in x264 format and need to convert to xvid for playback in
dvd player via USB.
I dont care much about the output filesize, it is ok if the size increases,
i want to preserve as much quality as possible.
basically i dont want to manually set any overall bitrate.

I think you're probably looking for concatenation
Something like this:
ffmpeg -i "concat:input1.mpg|input2.mpg|input3.mpg" -c copy output.mpg

There could be a framerate change involved
but we can't know for sure without console
output...

Hi
I would like to copy a ProRes file to another proves file changing the
framerate.
But in changing the frame rate I don’t want to interpolate the frames.
I’alike to take the number of frame of the source and have the exact frames
amount in the destination files but changing the frame rate.

I will re-issue the command and provide the full output.

Do you want to change playback speed? This is possible
with the setpts filter but needs reenc
Any possibility without re-encoding ?
Just copy the frames ?

I ran into an issue with ffmpeg tonight where I could not trim a source
because of the audio channel configuration of the track I was pulling audio
from. The source has a track of 12 channels of audio. I can process the
first two channels in the track to a stereo output with the pan filter. If
