[Rafael Amador] “If an scene “deserves” more data rate, it doesn’t get it. “ But if the CBR bitrate is high, like I’m suggesting it ALWAYS gets it, the problem is when an image pixelations it is because the VBR is not see it as something that needs a higher bitrate. There is no benefit to high bitrate VBR and many times they produce lower quality. You need at least 20-30 minutes for give VBR a chance to average it out. But do test, I will but up anything encoded in compressor as 7 Mpbs CBR against Compressor’s VBR at any bitrate, both in terms of quality and playability.
[Rafael Amador] “rom an Upper first movie you get an Upper first MPEG-2. Standard and playable everywhere..”
My point is to keep the field order as is, a lot of people (and at times Compressor) swop the field order and make it lower. Yours is a better (more correct) explanation.
[Rafael Amador] “Sending to Compressor duplicates the process time in case of a “Double Pass”. “
There is a hugh benefit to this when you are working with HDV sequence, doing it your way minimizes the HDV problem but this is still just you the best quality. But this suggestion goes hand in hand with my recommendation to use CBR, in the end it is quicker to Send to Compressor (or Export to Compressor) and use CBR vs, exporting a ProRes and then use VBR. Once again this is a step that give better results, especially if there is text and graphics. The sequence doesn’t need (nor should it be) rendered before starting the process.
As far as the Frame control, it is not as important as retiming, de-interlacing or up converting but I didn’t say don’t use it, I would test it with or without it. Any recommendation by anyone (especially me) should be done without testing.
