hitch in animation
My switch from Cinewave to Kona LH has been flawless except for this:
I’ve got some files with alpha channels that won’t playback or render properly. The clips are typically a second or so and they always stutter, double-frame, etc. in the last bit of the clip. They’re transitions that cover up a cut on a lower video track, alpha compositing. Alpha keying shows up correctly.
The files are Animation codec, 720×486 29.97 (rendered and live were OK in Cinewave)
Sequence is Kona 525 8bit uncompressed, same frame size and rate.Tried recompressing into all sorts of formats with no luck.
Latest versions of Kona, OS X, FCP, QT, Xserve RAID. 2gb RAM
Any ideas?

Hmmm, I do this all the time with transitions for projects. Were the animations rendered lower field first when you made them? Sounds like they were rendered full frame or they were rendered in the reverse field order.

Hey. Thanks.
Our graphics guy created the graphics for a show that’s a few years old, so he’s long gone and we no longer have the software that created the files.
My work is FCP only. Anything I can do within FCP to fix it?

Right click on one of the Animations and tell me what the Item Properties are and maybe we can do something to help you out. I’m looking for frame size, codec and I think it will tell you the field order but I can’t remember.

The files have these attributes:
720×486 29.97, Animation codec
pixel aspect NTSC-CCIR 601
field dom. Lower (even)I spoke with the graphics person. He wasn’t sure but remembered the system he was using defaulted to full frame.

in my experience Animation codec files should not have a field order defined.”Actually in my experience they do need to have the fields defined or you get a bad “reverse interlaced” look in 720×486 interlace timelines.
According to what he’s posting everything looks right, I’m not sure why he’s getting the look that he is.

Funny, I stopped using field order sometime back for the animation files when I was jumping between machines / platforms / Apps.
Since that time I have not had these issues because I was letting the applications force their own field order.
it just shows there is never one answer to any question.
