Cinelerra > worked great for me. I will give Cinelerra a try. Can you recommend a tutorial? I want best quality, but I don't need much for editing, a simple transition, a title, fade in fade out, 2x2 tracks for audio to mix the original stereo audio with a mp3-file. > Take care that you wast as little information in the intermediate format.

Does the stabilizer work only with deinterlaced material? Since I would create a DVD and a x264,file I thought I will deinterlace, when creating the x264- file. > I have no idea what > the stabilize plugin is doing with the interlaced clip.

I fear that bots consume a lot bandwidth so I didn't put it on my own webspace.

I suspect that your camera produces a clip with > borders. Could be, The file was captured with a Canopus ADVC 50. I would like to remove them and enlarge it to 704x576 or 720x576. I think 704 would be better, when you look at the sample. How can I remove these borders. I will play with the values myself, but I need the options how to do it in best quality. > > Can the colors / saturation be optimized automatically? > > What else could be done with this clip? > > > > > > Result should be a Standard PAL-DVD. > > > > I read http://public.hronopik.de/vid.stab/features.php?lang=en but I am > > very unsure which options I have to use. > > transcode -J stabilize -i MOVIE -y null,null -o dummy > transcode -J transform -i MOVIE OUTPUTOPTIONS -o STABILE I ignored OUTPUTOPTIONS and hoped that the default values are ok. Did I miss some important OUTPUTOPTIONS? Al
