Export with alpha (millions +)
BTW: an alpha BG looks black ...but is actually transparent
I have always exported with the alpha channel (millions + as shown above) using the Quicktime Animation codec. Virtually lossless.
There are other ways. You can export to a numbered series of stills instead.
However, I have to ask, why not just use Dynamic Link to put the comp on the sequence?
Quicktime Animation codec. Virtually lossless.
Actually, it's mathematically lossless.
I just didn't feel like explaining what happens when you apply effects. Any time you have to have the computer combine the original video with something new, there is some change that could be considered "loss", but I figured "virtually" was close enough.
I can't use Dynamic Link because I'm importing into an earlier version (CS5.5).
Unfortunately I had problems with Premiere CS6 and had to revert.
Another way round it I've discovered is to simply add Ultra Key to the clip once it's in Premiere and key out the black.
Seems to work OK. What do you think?
You can just open AE up then by itself then export the clip with a ALPHA channel. Because keying out black isn't a good long term idea. For one main reason you won't ever be able to use any black in your graphics. It also requires extra power from your system to process the Ultra key effect. Which you can avoid having to do by exporting from AE with a Alpha Channel. You can also export graphics with alpha channels from Premiere as well if you're more comfortable with Premiere.
You really don't want to key out the black. Truly, take the time to find the way to export an alpha channel. It isn't difficult.
Use the Animation codec, use a numbered squence of images, anything other than just giving up and trying to key out the background.
Any time you have to have the computer combine the original video with something new, there is some change that could be considered "loss"
That's not really the determining factor on this one, though. The issue is whether or not the codec itself will cause any information to be thrown out that can't later be perfectly reconstructed without errors. With the Animation codec, none is.
And that's a good thing.
True. I was just trying to avoid the argument the other way. I agree with you. It is just that I have had to defend my use of the word "lossless" before, and thought I could avoid it. All it did was cause more trouble.
