Thank you for your valuable input. What i actually want is to export the frames to an SDI card like decklink or AJA Kona, but the results of exporting through SDI are similar to an exported pal-dv movie. The expected result is a smooth animation without flickering which should be possible with 25fps but there are software available that can render animations in realtime to SDI cards without any flickering. I have been using vizrt (www.vizrt.com) in my company which is based on windows(directx) and use bluefish444 LT cards to send output without any flickering at all speeds. I have tried using quicktime's ICM and decklink SDK but the results are the same. I hope this the information you need to understand the issue but if there is anything else you would like to know please do let me know I will have a look at quartz crystal and will get back to you with the results.
thanks Nisar Subject: Re: exporting a composition to a quicktime movie From: dokt...@mac.com Date: Fri, 24 Dec 2010 16:18:01 -0500 CC: quartzcomposer-dev@lists.apple.com To: nisar...@hotmail.com It might be helpful to describe why the movie is poor. What is the expected result, what do you actually see, etc. If the issue is flickering text, then yes, Quartz Composer renders at 60fps, DV @ 25 will make the title crawl look choppy since there are less frames to show the text crawl between two positions. Doing smooth titles is not easy at high speed, low framerate, there are some tricks you can do, but the best thing is to adjust the speed of the scrolling until it looks good. Maybe look into Quartz Crystal from Kineme and use frame blending which will help ease the "pops" in position between consecutive frames. Is that the issue you are noticing?

I am attaching the composition you can try opening it with quicktime pro and exporting it to dv-pal movie 25fps and see the result. I have also tried other combinations but failed to reproduce the expected result.
