Uncompressed + DV Question
Hi, (Did a fair amount of searching on this first , but didn’t come up with the exact answers I need)
I am finishing a project that originated in PAL DigiBeta. I edited using cloned copies in DVCAM, so my timeline is now in DV format. Our plan is to online from the original DigiBeta tapes to Uncompressed 10-bit. And then down the road we will make an HD version by uprezing the Uncompressed footage to HD.
I am creating all my motion graphics/subtitles/etc in After Effects. Here is my question:
I still need to send out screening copies etc in DV and would like the graphics to be as high quality as possible. Should I render out my sequences from After Effects as 10-bit uncompresed and mix them in my DV Timeline? Or should I stick with DV, and wait to incorporate the Uncompressed versions until I online from the DigiBeta?
Also, as far as I can tell, After Effects cannot export Uncompressed with an Alpha Channel. For my graphics that need an alpha channel, should I use Animation Codec to give me the best quality?
As for HD, I assume I should create another set of exports from After Effects in HD when the time comes, rather than uprezing the SD graphics to HD, correct?
BTW, I’m using a Dual 2.0 (PCI-X) with 2.5GB of RAM and a SATA Raid.
thank you…

You can leave your sequence DV and put your Animation (millions of colors+ with alpha set to straight) graphics over it. Then you’ll have your hirez graphics later. For the best quality graphics in your screening copies, you can change the compressor to 10 bit uncomprressed (personally, I think 8 bit is fine) render that and output your movie.
Not sure about your HD questions.
Have a wonderful day.

Hi Chris,
Thanks for your reply.
Good suggestion about changing the compressor to Uncompressed before output. Screening copies are going out on DVD, so I can just send the Uncompressed output to Compressor for my MPEGs.

For the record, I always have way better lock rendering alphas premultiplied with black out of AE and setting the alpha to black in FCP.
Mlondon, you can always online later if your dv clones have matching timecode to your digibeta. It yield much better results than rendering your dv footage into uncompressed. Chris is right, it is best to create your graphics at uncompressed size (720×576 for PAL?) in the animation codec. That way you won’t have to recreate or rerender out of after effects for your online.
