dv edit size question
I am a graphic artist at my workplace. Until recently I have rendered all my stuff at 720/486, using the Meridian codec. We have recently switched to DV, which is 720/480. I have been under the impression that I should still render my keyable graphics out using Meridian, because the DV codec doesn’t allow an embedded matte channel.
Today our editor and myself have been trying to figure out the problems we have been having mixing these two sizes. Does importing a 720/486 graphic into a 720/480 sequence force that sequence up to 720/486? We have been trying to export clips from the sequence, and they keep coming out the larger size. When we force the export to use the DV size settings, we get a black bar on the bottom of the exported movie, and sometime the fields get blended together. And, when we did one export, the video under the graphic was one size, and when the graphic ended it jumped to a larger size.
The questions are: does inserting a 720/486 media into a DV sequence (at 720/480) force the sequence to be the higher resolution?
If so, what is the solution? Does Avid Meridian allow renders at 720/480? What output settings are preferred?
Thanks

just live in the land of 720X486. Anything int he workflow will be this in the end… or should be considered as such.
go ahead and keep rendering at 720X486 as well

But then how do I get decent video for posting? For instance, we did a chroma shoot that was all jacked up because the fields were blended together. How do we keep a sequence locked in at 720/480?

You can’t even create a project at that size.
If shooting chroma key elements, do not use a compressed source at 5:1 in a 4:1:1 color. You will always have a hard time making DV look like tv. You can get away with using it as b-roll if you have nothing else but it’s not meant for stuff like keying. -
In the past I have had our chromakeys shot on our Betacam camera back, which is 720/486 when captured using the Meridian codec. That pulled good keys. But the Betacam format is no longer supported, and the last time we used the camera back it screwed up the video because it’s worn out, and it isn’t worth fixing.
People can and do use DV for chromakeys. My questions were aimed at Avid users who do. How do people get Avid to export video at the same resolution at which it was shot and captured?
