Is it Ideal to overlay 720 by 576i50 animated graphics on top of a progressive video?

(for both video and graphics) Render settings: "Best Settings" > Fields: upper fields - for the purpose of graphics only

Lossless: Apple ProRess (LT) 720 by 576i PAL Widescreen 1.46 (16:9) D1/DV.

Once rendered the video its self is still "progressive" only the graphics are now "interlaced".

Ideal? By no means.

You may find better results if you deinterlace the graphics first, create a new file, and use the new file.
 
I would disagree with the last part. Even if your delivery is interlaced, keeping everything progressive until delivery is almost always going to be your better bet. Exceptions may apply, but they're exceptions.

True, I was thinking more in terms of the other stuff like frame rate, size, standards, etc, but since we're talking about interlace (blech! phoo!) I should have been more specific. However, if you know that your delivery is only going to be interlaced, and your footage is already shot interlaced, then I'd think it best to stick with an entirely interlaced workflow, no? If your footage isn't shot interlaced, then yeah…do it all progressive.

Would disagree on frame rate as well; you should choose your frame rate based on what you your motion to look like, and edit in the native frame rate of what you shot. You can deliver however you need to.

That's assuming you're talking about shooting 24 or 30 and delivering at 60 for broadcast or something, of course; if you need to deliver at a slower rate, then it doesn't make much sense to shoot a faster one.

(And if you're going to cross standards, like from NTSC to PAL, well, that gets pretty involved. :) )

However, if you know that your delivery is only going to be interlaced, and your footage is already shot interlaced, then I'd think it best to stick with an entirely interlaced workflow, no?

Yeah, I don't disagree with that at all.
