[Rob Wynn] “I have three sequences I want to put in my iDVD project but don’t know where to find them on my computer. When I exported the sequences as Quicktime movies the quality was reduced.”
Well, you say that you don’t find them, but you say they have reduced quality.
If you don’t find them how can you know they have lower quality?

You must export QT movie with the higher quality you can in order to get a good DVD out of iDVD.
What kind of footage have you used?
Which are you sequence settings?
Have you applied any effect, resizing or whatever to the footage/

[Ofer Geva] ” all recorders that recored a Prores 422 HQ encoded file record the same bit rate?”
No.
Beside the fact that is a VBR codec, it will depend of the hardware you use for the compression.
codecs are sets of rules/recommendations for compression/decompression and they can be implemented with certain variations by different chips, so you may get some differences when using hardware from different manufacturers.

I’m not much sure how to make a CBR H264. I guess, beside limiting the data rate, would be necessary to set a key-frames value, so all the GOPs would have the same length and structure.
The problem is which key-frames value to set. You have no way to know which one is the optimal. The optimal GOP length depends of the picture contents (movement, detail, shots,..).

Personally I don’t see a single reason to use CBR. You just get a less efficient compression and so, some times less quality.

You exported a reference movie from FC.
In the export window, click “Make self-contained”.

Reference movies are like a play list of the original media or the rendered files. Without them, the movie won’t play.

Hi Phil,
I have no experience with RED footage, but what I can tell you for sure is that FC do not support video bigger than 2K.

[Bill Davis] “Funny, I kept reading the post over and over and over – and I never saw the word “fix” anywhere in it.”
Except with the story of the Apples Maps for the iPhone, Apple has never recognized and will never recognize that there is any thing to be be fixed on their products.

Don’t know the reason of the warning, but I had the issue long ago with DV footage.
I didn’t pay any attention and things worked without problems.
