It’s a great site but it’s very out of date. A number of the codecs listed don’t exist anymore and there are many new ones that are not listed.

Look under 4:4:4 and 4:2:2 C
There’s little to choose between PhotoJPEG and Animation when both set to 100% or best.
Re PhotoJPEG:
“PhotoJPEG at its highest 100% quality setting is actually a 4:4:4 codec. When reduced down to 75%, it switches to 4:2:2 to help with the compression scheme”
…….
“This codec truly can pass for an online codec with no problem. Best part is this codec is free to any QuickTime user, can be used on any platform and runs great even on PowerBooks.”__________________________________________________________________

Use compressors frame control deinterlace rather than the deinterlace filter

Oh, I didn’t doubt that they were probably re-coding it, I was just pointing out that high quality was possible at considerably lower rates than were being discussed.
Mezzanine for me is 50Mb/s MPEG-2 but I’ll sometimes go to 30Mb/s.

[Dixon Johnston] “Daniel, So you’re saying that the file has been basically maxed out for the codec and it doesnt require any higher bitrate to maintain its quality?”
Correct.
I’d also like to point out that H.264 is a highly efficient format and the datarates you are delivering are HUGE for the given content and frame size.
Like I said in previous post, I’ve seen stunning 1080p at less that half that datarate. (But you need to know exactly what you are doing to achieve that).
That said, what the customer wants, the customer gets. (Unless they are totally wrong or way off the mark)

[Dixon Johnston] “This afternoon, another 30 sec spot with the same settings will not exceed 6.5Mbs. Ive tried ‘restrict to 15000kbs” as an experiment, but it is not helping my bitrate problem. “
Do you use CBR or VBR rate control?
Simply put, your content didn’t require anymore than 6.5Mb/s. The only way to ensure a datarate is to use an I-Frame only format, otherwise known as ‘constrained’
Examples are:
DV
DVCPRO
IMXThese are based on MPEG-2

The only way is to compare the two transcode settings
As for PPC vers Intel, you need to check out this:

[Paul Willetts] “The file is about 1GB. Does anybody have any suggestions as to how I might compress or zip the file to reduce the size while still maintaining the quality”
You can’t
By Zipping it, you are likely to increase the file size not reduce it.
If you want to get the VOB smaller you’ll need to transcode it, and that will reduce the quality.

[Adam Liss] “Do you know of any way to get more detail on how something is encoded than what QT gives you”
What are you trying to find out?

It’s possible it could be compressor if you have mixed interlace and progressive content and didn’t apply a deinterlace control.
By the looks of it both animation and video are progressive?
I’d really need to know detailed information on your AE comp settings, your FCP sequence settings and your compressor settings before I could make a final call.
