Not if you will, but I work with videos mod, do the following. Open file with avidemux
Video > copy Audio > copy format > mpeg-ts (A + V) save with extension mpg The resulting file in cinelerra works without problems, until now. To pass it on to DVD you could try to render in "MPEG video" dvd mpeg2 format, and audio "audio mpg" layer II All this now maybe you can not use, because you're all done. lucky, YosepkeY 2010/12/30 Herman Robak <[email protected]> > Forwarding this to the proper mailing list address: > > ------- Forwarded message ------- > From: "Sape Sikkema (Telfort)" <[email protected]> > To: [email protected] > Cc: > Subject: Jerky movements in rendered movies > Date: Thu, 30 Dec 2010 13:28:27 +0100 > > Dear Sir, > > I'm using Cinelerra for a while, but I haven't been able to produce an > acceptable end result.
