The best solution I have tried is to make a render with a 720*576 size and to limit the rate at 1000kb/s.
I tried to cut the sequence and to compress the different parts of it but it didn’t work very well…
Maybe I used bad settings.
My composition lasts 30 seconds and has an “integral” resolution, each vertical and horizontal pixel is took into account.
I don’t know if that can help you…
