HD frame per second rates

[Morne]

Hi all

I'm about to dive into HD and I think I fully understand the resolution issues for HD. I mainly do animation so it will be 1080p is this correct? As in 1920 X 1080 non interlaced (also knows as progressive). I need playback in blue-ray discs and also I need playback on laptop straight from hdd.


Anyway my question is, do you also get PAL and NTSC versions of HD like with normal tv, or is HD just plain HD, no pal or ntsc or whatever? Also is the frame rate fixed at 60 frames per second or can I make a 1080p blue-ray movie with for example 24 frames per second?

Regards,
Morne

Hi there,

I recently did some stills and animations in HD that were played in an Imax theatre. The framerate I had to set everything to was 25fps.

Render res was 1920x1080 as you said already.

Thanks for the reply. Was it played back from HDD or from a bluray disc? or was it just files played from a normal dvd? If so what format was it in? QT?

The kind of animations I do needs to be looped over and over as it is played at exhibitions. Also I need some kind of menu so I can play and loop for example only chapter3 or whatever.
What's the best way going about this?

Im not actually doing the DVD. That is being done by another agency. As far as Im aware though the whole animation was output to a quicktime at 25fps (uncompressed) and then bought into a DVD authoring package..more than likely Adobe Encore.

Well, if you are wanting control over the film being shown you can either set the movies to play on a computer and just select the movie you want to loop manually. I would say that outputing to mp4 would be the best solution. Mp4 can be played directly from most media players.

Alternativly, you can burn the films to blu-ray disc and create a menu system with adobe encore. If you dont have adobe encore there are other programmes out there. Also, you could just download the trial to test these things out. Im not sure if you can do commercial stuff with trials though.

Ive asked my client what the Imax animations were played from...hopefully should hear back soon.

EDIT: The client said it was played from HD-cam tape. Ive not heard of that. Also, you can use h264 compression as well. I think that is used quite often for blu-ray. Dont take my word for it though as Ive not done any yet..this is stuff ive just heard. There should be some good info on the Adobe forums.
