checking for "real time"

Hi, all,

What are the various ways some of you check your graphic builds in real time? I have a dual G5, 2gb ram, Motion v2, and after adding a handful of replicators, filters, motions and so on, things bog down. I know that there is a lot going on, and I can still see things happening, yet slowly. The only way I can see it in real time is to make a QT movie and checking it out.

Is this the workflow you folks use?

Appreciate your comments and have a great Fourth!

What graphics card are you using?

The standard card that came with my G5, ATI Radeon 9600. Could that be the culprit?



Cameron Young

Absolutely, the graphics card is the most important part when it comes to Motion.

Well, that goes on the laundry list of upgrade-to-do's......I'll just have to do my QT work around for now.

Thanks

You can also do a RAM Preview to see your work in real time (cmd-R).

Greg, I've found that the RAM preview doesn't guarantee real-time playback - sometimes playback is real-time, sometimes it is slower. Why is that?
Mark

Probably because you don't have enough RAM to completely cache the project.

are we talking about computer RAM?.....I would think that 2 gigs RAM would be pretty adequate, no?

As a follow up to the above discussion. I found an article on the Apple site that addresses this.

I guess I better start including these articles in my searches. What worked for me was dropping the resolution. The project played nicely, and it is easy enough switching back to full rez and continue building.

Have a great weekend, all!

No matter how powerful the graphics card, in my experience the RT thing is only really useful for simple projects. You can still take advantage of it other projects, by using the solo function a lot, ie, RT playback of individual elements rather than the whole thing. The truth is that elaborate motion graphics projects get complex really fast and the whole OpenGL thing becomes less relevant when that happens . Specially considering that particles and simulation behaviors are mostly CPU based, rather than GPU based. With the sad fact that building RAM previews in Motion is sometimes really slow. That's why in my opinion Motion could really take advantage of an alternative software rendering technology, that should kick in when things go beyond the OpenGL rendering capabilities.
