Subject: [Motion-user] Variable Bit Rate and importing into video
editting apps
Message-ID:
<[email protected]>
Content-Type: text/plain; charset="UTF-8"
Recently I've been experimenting with importing multiple mp4 webcam
clips into video editors. e.g. a day's worth of clips from a garden
webcam. I don't have any great experience of editting programs so I'm
simultaneously doing a bit of ad-hoc evaluation of what might work best
for me. Currently I'm messing about with kdenlive and shotcut.
When I tried to import a batch of mp4 files into kdenlive it told me
they were vbr. Its options for automatic batch conversion failed so I
looked at my motion.conf files, and set:
# The encoding quality of the movie. (0=use bitrate. 1=worst
quality, 100=best)
movie_quality 0
# Container/Codec to used for the movie. See motion_guide.html
movie_codec mp4
# Duplicate frames to achieve "framerate" fps.
movie_duplicate_frames on
I thought this would do the trick but both kdenlive and shotcut report
these as vbr. Perhaps they are, and I'm not convinced it's a bad thing.
One thing that occurred to me is that perhaps this that perhaps I've
misunderstood the movie_quality option and should have it set to 100.
So I guess I have two questions (one off-topic)
1. What apps do people use to edit the footage they get from their
cameras?
2. Is there a particular combination of options and values that I
should use to make it easier for later editing?

I'm certainly not an expert on this subject, but ffmpeg from the command
line can do a lot depending on what you want to do.
