Cross Dissolves at 1080i

[Jeremy Garchow]

What kind of processor and what codec? Two streams and cross dissolve is really 3 streams or more.

actually that’s based on the speed of your system and how you have the timeline set up. Are you set up for Unlimited RT? Are you set up for Dynamic Playback?

And what codec?????

[Russell Lasson]

And what color is your render bar? Red, green, orange, grey, purple? (It isn’t purple you’ve probably got some serious problems.)

Sorry 10 bit uncompressed 4:2:2 , red render bar, standard RT

[Jeremy Garchow]

Yep, that’s why. Trying to compress a cross dissolve or any other effect on the fly with 1080i UC 10 bit takes a TON of horsepower. Try using DVCPro HD or ProRes for more rt. Remember, not only are you playing back the tow streams, but you are also adding a third stream (which is the cross dissolve) and the calculating of the processing that goes with it. It’s a lot to handle at such high data rates.
