720p
i create a comp at 720×1280 the client wants this vertical and i did it at 29.97fps just for the design because that is how it’s going to be shown and rendered it as lower field first. The delivery is 1280×720
and the system that they have to broadcast this would rotate the image vertical. So I droped my 720×1280 into a 1280×720 comp and rotated this +90, they are asking for 720p without compression.
What should I render this as, should I use lowerfield first or the comp is 29.97. they are asking for 720p
what do I do for this? please help i have to get this job out now. -

if they specified 720 progressive at 29.97 fps uncompressed, then that would be what i would give them. i would not render any fields or modify the frame rate in the render settings.
as for the format/file type or codec… that is there call. if they said ‘uncompressed” i would tend to think they want an uncompressed avi file, but you can also create uncompressed mov (quicktime) files and even mxf files, and there are uncompressed image sequences like tiff or targa, so i think would call them to get clarification on the file type.

do i use lower field, and they did not specify the frame rate this is what i designed it in, does it matter if it’s 29.97 or 60fps…what is the standard for 720P and should I render with fields?
-
720p is progressive, so do not render in fields.
the standard frame rate for 720p is 59.94, so if they did not specify the 29.97, then i would imagine that they are expecting 59.94, you should be able to just change the final comp’s frame rate to 59.94 fps, render that and be ok (keeping the same frame rate).

if i deliver in 29.97 would it be a problem?

i don’t think it would cause any problems, but i don’t know anything about their playout system… since they are playing out uncompressed hd, i assume there playout is through a computer with a fairly large, fairly fast disk array. most software players should care much about frame rate, so i doubt there would be a problem… but again, i don’t actually know their system, so i can’t know for sure…

i guess i will keep it at 29.97 i can’t watch it on my computer my drive in not fast enough. this is all pics like a slide show. would it matter about the frame rate? what would this look like in 59.94 would there be a difference in quality and performance?

59.94 would look smoother and crisper, but unless your movement was pretty quick (and it doesn’t sound like it would be), i doubt anyone could tell the difference.
as far as performance, it would double the data rate required to play back the footage, so going with 29.97 would be a lot less demanding on a system.
