Movie Specs

Hi

When i'm using HD movies i'll preffer Photo JPEG A at 60% compression
When SD DV PAL
Some graphic guyz preffer to use apple intermedia codec cause they say it's better, but i see no difference (and there is no difference in catalyst performance)

If i have to use SDI i'm using Image PRO HD or SD

1024x768@75 (best res if U need convert DVI/VGA signal to SDI SD) cause sometimes I must use old MAC based on G5 processor.

last time i checked - AIC had double the performance of photojpeg 60%- twice as many layers at the same time- and i test up to 32 layers at the same time-

and is critical with hi-def and once you start using more than 6 layers- nothing else works well enough-

and a lot of people are doing this-

the fact that you cant see any difference is a good thing... ( as codec degradation is counter intuitive ... its much harder to encode a poor quality noisy image than a pristine clean one ... the opposite performance expectation to analogue video)

AIC is much much better than dv-pal-
and preserves much more graphics quality-
and dvpal only works at a single image size 720x576 -

but i have been involved in films for a long time, and dv-pal was good enough to broadcast in 1995... when dv cameras first came out -

I do tons with SDI. Actually HD-SDI. You will not see a difference at your specifications. In order for PhotoJPEG to exceed the quality of AIC, you will need to change your compression level to more than 80%. Still then, the change is so negligible you would have to have screens side by side as a comparison. In fact, even in the preview and program windows of a multiview, you can't see the difference.

Where you'll really see the value of PhotoJPEG is in native DVI matching pixels and refresh rates with your native output device. Still though, LCD and DLP will have different levels of clarity.

The bottom line is to stick with AIC unless absolutely necessary to change.

and photojpeg has much worse performance than aic.
much worse.
and at 80% photojpeg and greater its usually very bad-

on a recent show i changed a photojpeg 75% file to aic and it halved the time per frame - 12ms for photojpeg to - 6ms for aic. same image. same computer - no other changes.
and this can be the difference between things working well or not working well at all.
