    Just as an example,... we had a event wich the movies are BLACK and WHITE, and we achived 5 layers of 1080p... so all depends on the content.
    the jpeg algorithms used in most codecs are sensitive to data rate of the movie-

    the more information in a frame - the higher the data rate - the longer it takes to decode.

    black and white movies usually have lower data rates - so can be decompressed faster

    each frame in a movie ( in most movie files ) has different amounts of information - and decompress time varies throughout movie playback-

    so its not dependant on the weather - its dependant on the movie data rates - and this varies on the type of images.
    and everyones images are different.

    I've never got more than 4 layers of AIC at 1080p 25fps on ANY MacPro... not even the same spec as you quoted.
    How do you manage to get 6-8 layers on 2009/2010 MacPros?

    suggest you run test G on your systems and send charts.

    and we can check the spec of the machines you have-

    there isnt much mystery to performance - every machine is different

    using test G on a folder full of the same file type - image and codec - with different movies

    i didnt optimise or use latest hardware - i like to test on older systems - so this is not optimised to get best performance.
    2009 mac pro 2.26GHz 8 core 10.6.4 GT120 - ssd
    tests with gt120 ( which isnt great and is not recommended ) - on old mtron ssd - 1920x1080 output

    first file is range of codecs from photojpeg to prores
    second file shows 1080p AIC 6-7 layers - 30 different aic files
    third file 20 layers 720x576 AIC

    ---

    performance tests are not in show context and every machine needs to be tested by end users

    this is only a general indicator not a specification

    Hi Richard, is it possible that you provide some test files in different resolutions so that I can test my machine with the similar files that you use and compare.

    Can you comment on quad cores machines and 8 cores machine. Will the 8 cores machines be able to run more layers than the quad cores since you mention that 10.6.x uses all cores.

    the point is that all content is different - so you have to use your own files.
    or what you have access to.
    cores arent important unless you have a lot of layers.

    the order of importance is

    1. codec for file -
    2. ssd
    3. cpu and graphics card

    In a 2009:
    8 core 2.26
    8GB RAM
    OCZ 250GB
    1920x1080 x 2

    Using AIC AND general After Effects content I have seen:
    4 layers on out 1 and 4 layers on out 2 at 25FPS (8 total layers) no FX
    3 layers on out 1 and 3 layers on out 2 at 30FPS (6 total layers) no FX

    I have tried the same thing however, with the same size content but content that is much more vibrantly colored and complex (like HD footage of nature) that caused frame drop.

    TODD SCRUTCHFIELD

    ...if it ain't broke...
    gimme 5 and then don't act surprised
