Working with HD in AE

[Jack Hilkewich]

Thanks for all the help guys, Jasye, the pdf looks awesome great tips!

I have a question when I create a proxy of HD footage should I use the same dimensions as the original? The default setting when making a proxy reduced it by half, now I’m not sure if that is the way I should use it or not.

You could, but then it would be just as big and unwieldy as the original. There would be no point.

“You could, but then it would be just as big and unwieldy as the original. There would be no point.”

The avid help files say that I should keep the same dimensions. I don’t have it open now but it was due to the time it would take to rescale things or something like that. How will this affect the masks that I use. Will they be as accurate if I am using them on scaled down footage?

Umm … I’m confused. Avid?

When you render out of AE, you have to render to the final size of the sequence/timeline/whatever that the Avid wants. This has nothing to do with proxies and scaling in AE.

You use the proxies within AE. When you’re done in AE, you then switch off the proxies so you’re working in full-res, then you start the render and go for lunch/dinner/vacation. When the render is done, you import the clip into the Avid.

Now if your Avid project is HD, you should have rendered out of AE to HD. However, if your Avid project is SD, then you should have rendered out of AE to SD (to save the Avid’s having to scale it down), possibly by using SD proxies in an HD comp, and by leaving the proxy in the comp so it renders as SD.

Does that help?

Regarding masks, have you tried making proxies according to the instructions in the help?

I am sorry , I did mean the After Effects Help files.

I checked them again and it said to keep the same aspect ratio, not the dimensions. I mis-remembered.

AE scales up the proxy to match the dimensions and length of the original. that is from the help files. Now if I create a bunch of animated masks and stuff will their position be correct when I go back to my original?

Thanks for your help.
