Timing and playback speeds of frame-rates

[ryanww]

Well I am unsure of the specs yet on the computer that will be running it. Currently I am on my Mac pro, 2x2.8 quad 6 gig ram 8800gt. I am running it off a 10k raptor drive as I don't have an SSD yet. May buy one. But I am not all that sure it will be necessary as this clip will be the only thing playing from it other then a logo that the output will switch back and forth with. This will be projected on a screen with a double stacked set of panasonic 7700's most likely. (DLP 7k projectors). Currently I am just using my LCD display for testing.. I can hook up a little notebook projector if needed.

I have gotten the final content from the client. Attached is the specs on the file listed from FCP. What would you reccomend I do with it? Convert it straight to AIC or go through uncompressed to AIC with 30FPS?

And It wasn't that my computer never ran it smoothly, I just am trying to figure out why a movie that was encoded in 23.98fps was very choppy if cat was set to the same frame rate. My master clip is also encoded in 23.98FPS.

Thanks!

Personally I would ask your content folks to send you a quicktime uncompressed at 30fps version of the file and then encode into AIC and hold onto the uncompressed version. That will solve 99% of problems like this, also it is always good to get content sent as uncompressed unless your content providers are house trained and encode correctly in AIC.

If you cannot get the file uncompressed, then go the route Todd suggests, not forgetting to De-interlace the file before encoding to uncompressed.

BTW catalyst media playback is built upon quicktime, only the capture card side of things bypasses quicktime. But Catalyst is not good bedfellows with MPEG based content because it not frame absolute, Richard could possibly elaborate this.

if movie was shot at 23.98 - and post-produced at that frame rate -

you really cant do any frame rate conversions - they wont work-

changing the frame rate will just duplicate frames - or do something horrible to the content like frame blend.
Frame blending will alter the content in a way which might be completely unacceptable to client-
