Well, I started working on my first video with cinelerra today and have been
very impressed by what it can do. However, I ran into a problem when I went to
render my video.
To start off I am running the following:
Gentoo Linux
Cinelerra 2.1CV (latest version available in Portage)
The video I am using came from my digital camera which was converted in "batch"
to dv using this handy little command I put together:
mkdir converted && ls | xargs -i ffmpeg -i {} -target ntsc-dv converted/{}.dv
My timeline consists of several affects and layers are used in multiple places
(either two videos at once or a video and some image(s)).
The video and audio are in sync in the timeline for the most part. It goes out
of sync a little whenever there are some affects on the screen or whenever
there are multiple layers of video or pictures being played at once. However,
that is to be expected (I think).
Anyway, I first tried to render my video by going to file, then render,
choosing Micrsoft AVI for the file container, mp3 for the audio, and mpeg-4 for
the video. After a little waiting it renders and everything seems fine,
however when I play the video the audio becomes more and more out of sync with
the video until by the end of the video there is no audio to match it.
So, I head over to the documentation and take a look at what it says about
rendering. It recommends to use DV, Quicktime for Linux, and two's compliment
and then convert that. This poses a problem since I am dealing with video that
is 640x480, but for the sake of testing, I change the resolution and render it.
Unfortunately, I get the same exact audio sync problems.
I did several google searches, browsed this maillist a little, and read though
the documentation (specially the parts on rendering and the troubleshooting
section) with no luck. Any help would be greatly appreciated.
