Dont convert the file to a compressed DI and see if you get a better key .
Do the key work in a separate sequence then nest it back to the edit sequence maybe.
Work all the key fx tweaks.
Do the key before even thinking about changing the color to blue.(which might be challenging)
I would do it in AEFX anyway
Darn Adobe forum jive rubbish --- why is my Enter key broken...sheesh! ...and no smileys ( in this case..."angrys")
Start with a garbage matte to get rid of most of the middle part.
Then use Ultra Key instead of chroma key to key out the edges.
If you cannot get it right in one go apply the effect again.
I would actually cut out the green part in Photoshop an make it transparant.
Give it a bevel and drop shadow in Premiere to give it some depth.
Graig: this enter key thing is something I only get in Explorer not in Firefox.
Thanks for the tips.
Sorry its a . mov so forget about PS.
And Ultrakey is in Premiere, not AE. At least, I don't see it there. And I'll tell you right off the bat. Ultrakey is much better, even before tweaking anything
AE has Keylght, even more powerfull then Ultra Key.
Keylight - no tweaking needed. Changing curtain color is another story Playing with Change color effect, not change to color. Applying 3 times for different shades
I would not covert the frame rate, just change the frame rate under interpret footage it will run slightly at the wrong speed but that might not matter with a curtain opening.
