2. Re: Blu-Ray and resolution in CS5
SAFEHARBOR11 Nov 5, 2013 9:14 AM (in response to BrianSiano2)You should definitely have a 1920x1080i Blu-ray preset available under "H.264 Blu-Ray" format presets. Don't have access to look right now, but it is there, I've used it.
If you want to reframe the video, that happens before export. Put the 1080 footage into a 720 sequence, Scale to Frame OFF, and then you can manually scale/frame clips as needed, then export as 720p.

3. Re: Blu-Ray and resolution in CS5
BrianSiano2 Nov 5, 2013 9:25 AM (in response to SAFEHARBOR11)Jeff: thanks, but I think I'm on that page already. My concern is whether I can create a Blu-Ray video at 1280x720 and 29.97fps.
Do I have to go to a differet frame rate, like 24 or 23.97? Or do I have to scale the reframed video back up to 1920x1080 to match that 29.97 framerate?

SAFEHARBOR11 Nov 5, 2013 9:31 AM (in response to BrianSiano2)Hi Brian,
I don't have access to a Premiere system at the moment to look at available encoding options, sorry. But quite simply, take a look and see what the options are on your system. In AME, choose "H.264 Blu-ray" and then under Presets, what frame sizes and rates are there? If you see 720p30 (29.97) then you are all set
Thanks

TeeKayCC Nov 5, 2013 2:04 PM (in response to BrianSiano2)I've got Premiere CC open and the list of presets look incomplete to me.
You should definitely be able to do 1280x720 at 29.97 in theory. I'm not sure what Encore supports, but I'd be completely blown away if it didn't support this. It wouldn't make sense for Encore to not support this.
The preset isn't there for 29.97, but you can just tweak the framerate from the HD 720p 23.976 preset. There should be no need to upscale to 1920x1080, unless you absolutely need 1080p/i for some reason. Blu-ray definitely supports 720p and 720i at a number of framerates.
To answer your second question, rendering a Blu-ray video at 1080p at 29.97 fps should not cause any problems. But like I said, if your source sequence is 720p/i... you might as well export at that size and not upscale. It'll save you time and hard drive space. Not only that, but people's Blu-ray players can easily do the upscaling later.

6. Re: Blu-Ray and resolution in CS5
SAFEHARBOR11 Nov 5, 2013 2:29 PM (in response to TeeKayCC)Again, don't have a computer available right now to check presets, but the list of Blu-ray options is actually kind of small compared to what the cameras offer these days, the reason being that the Blu-ray spec governs what formats are supported (Blu-ray players can only play certain formats). For instance (going from memory) I don't think there is a 1080p option, just 1080i. And in reference to the previous post, there is no such thing as 720i, ever - 720p is always progressive. But if you edit the 1080i or 1080p footage in a 720p sequence, definitely aim to export to 720p Blu-ray, because you will lose quality upscaling to 1080 again. Keep it 720p.
Thanks

Stan Jones Nov 5, 2013 3:26 PM (in response to SAFEHARBOR11)Keep it 720p.
Agree.
For what its worth, the H.264 BD export, and Encore supported for import, is 720p 59.94.

Stan Jones Nov 5, 2013 3:31 PM (in response to TeeKayCC)The preset isn't there for 29.97, but you can just tweak the framerate from the HD 720p 23.976 preset.
The problem is that you have to have both what is Bluray legal (and for those cases where it may be more restrictive) what Encore supports - meaning what Encore will see as legal. It is best to stick with the H.264 Bluray format and those presets. They are there for a reason. To get 720p 29.97, you can use the H.264 format (i.e. no Bluray after it), which includes that as a preset. But Encore will re-transcode it.
