Great. So now this is the millions+ dollar question…
Can this alpha channel be ignored without problems in the future or any sort of quality loss, or do the files need to be recreated using Millions of colors without an alpha?thanks.
ps – Avid will sometimes ignore the alpha (i’ve changed the setting to “Ignore” in my import settings) and sometimes ask me to choose real time matte or a/v clip. It’s these inconsistencies that drive me mad. I’d prefer it just behaved badly all the time, or well all the time, so I could get a handle on what is happening.

Is there any way to figure out which files have an alpha channel before attempting a batch import? Do you know of any shareware that can tell you this information?
Thanks for your response.

Any word on tape vs. tapeless implementations as far as mixing frame rates goes?

Unfortunately, I cannot send out any images. the best I can do is describe it.
We’re dealing with a CU on a runner with no hills in the background and then an extreme zoom out to include the landscape. (so the white building will have to be painted out of the zoom as well) Once the zoom finishes, the movement is limited mostly to the slight handheld movements you typically see in DV handheld footage (Camera was a Canon XL2) So there isn’t a lot of major movement at those stages, when the camera is fully zoomed out, just the slight up-down-lef-right sporadic movement of a camera that isn’t locked down. The size of the white building is quite a small, unrecognizable rectangle.

yeah, i’m surprised nothing was caught earlier either. I’m not familiar with After Effects, so I don’t know if they would have seen jaggies or not. Maybe they got lucky and all the composites were done using footage that happened to have start timecodes ending in :x0 or :x5 and were in fact regular pulldown.
anyway, question answered. thanks for your help.

You are exactly the person I was hoping would respond, and simultaneously the person I was afraid to hear from. thanks for your response.
This project is full of bummers. More than just the above mentioned issues.
To answer your questions:“Although all Pullin columns say “A”, do all the START timecodes end on :x0 and :x5?”
Unfortunately, rarely. There is one bin I saw where all clips consistently have start timecodes ending with :x0, have NORM in the Cadence column, but unfortunately, may have been shot with Advanced pulldown, because as far as I can tell it was a C-Camera, so it wouldn’t have been the DP so there’s no telling. But most other bins have scattered timecode ending numbers. From what I’ve read on the forum, during log & capture, one should set their in point for a clip at a :x0 or :x5 frame. Is this correct? (Sidenote: The pullin letter changes for subclips. Is this normal or also a concern?)
“Display the Cadence column in the bin – does it show both ADVA and NORM or all of one or the other? ”
As far as I can tell, everything is NORM. I think he set it once for Regular Pulldown and left it that way.
I also posted on the Avid forum and was glad to hear it will only involve a recapture of the final sequence. The bad part about that is that there is so much compositing and effects that were done in the first part of the film, that I dread the fact that much of this may have to be eye-matched due to lack of planning, as the director never wanted to go back to the original tapes to do a conform. I know there are instances where portions of the film were output and worked on in After Effects and it would not surprise me if there was total disregard for timecode and tape information. This could end up being an expensive mistake. If you have any advice beyond the obvious ‘plan this stuff from the beginning’ or ‘don’t take on rescue projects’ sort of stuff, I’m all ears.
Thanks again for your response.

I can only point you my post for my major issues.

We’re in the early stages, so who knows what awaits us when we need to conform. I wouldn’t suggest it. Doesn’t seem solid enough.
