AE -> Encore for Bluray - How shall I prepare?
on Jun 29, 2008 at 6:28:58 am

Where I'm at: I've got a big (two hours, approximately) project all set up in one big After Effects CS3 composition. Currently it's 1080p at 59.94fps, and by that I mean 1920x1080p @ 59.94.

My decision to look into the Encore option is fairly recent, having already dispensed with the pure chaos of directly encoding MPEG4-AVC for the PS3. (In short, once I discovered that the PS3 had trouble stably playing anything over ~10Mbps, I realized how futile it all was.)

But I did learn enough to be wary. From what I can tell, Encore CS3 will take pretty much anything and spit out a Bluray image that should play on most Bluray players, fortunately including the PS3. This no-hands philosophy suggests that it will tend to transcode, scale, stretch, and otherwise manipulate the source video however it pleases - perhaps without even mentioning that it's doing it, just like how PPro doesn't - in order to keep things in spec. That has me worried.

Concern #1: In essence, this will be a two-part process. a) Encode the video into a Bluray-compatible H.264. b) Use Encore to generate a Bluray image from that video. How should I handle that? Encore supposedly has the ability to import AE CS3 projects directly. Would that be faster or slower than letting AE generate the encode itself? Would it even work with any reliability? (Theory is one thing; practice is reality.)

Concern #2: I've taken great pains to ensure that my video is 1080p from start to finish. Now, I recognize that I'm going to have to find a way to modify that into 1080i60 because 1080p60 exceeds the "level 4.1" profile. Would it be better to make that modification from withing AE, or trust Encore to properly handle the video itself?

Concern #3: I have read many times that in reality, only a 1920x1088 (or something else that's a multiple of 16) will actually work. So what does Encore do.. stretch the image? Add 8 lines of black to the bottom? Nothing? What does the PS3 do with those 8 lines if they have to be added?

Concern #4: I have also made certain to take full advantage RGB24's luma spectrum (0-255). That's the range that After Effects works in. I'm fairly sure at this point that an H.264 Bluray is YUV12 or something like that. Assuming that's right, then something is going to happen to my luma range and there's no way around it. So the question is: What? Does Encore squish the 0-255 to 16-235? Does it chop off the 0-15 and 236-255? Does it somehow pass the full range, leaving it up to the PS3 / TV to crush the blacks/whites? It's very difficult to test things like this, and obviously unwise to guess.

Yay. Maybe the answers to these questions can be added to some FAQ somewhere. ;p Thanks much for any help.

Well, what I would do assuming you are going to use a BluRay project and have all the correctly sized menus is render out a few short work areas of various parts of your file and import them into Encore.

Since I use Cineform for everything except rendering in Encore I can't be any help there, but you could look at message #9 here for some idea if you don't know what you want there
http://www.adobeforums.com/webx/.59b4ecf5/10

Then I'd just burn a short BluRay folder and image using that stuff .
That will give you some idea of what your stuff will look like on disk. I always use MPEG2 and not H264 when I have Encore automatically encode the project but ...

Naturally, you should burn the disk. For what it's worth I always us IMgBurn to burn either the folder to BD-RE which will play on a PS3 as well as a BluRay player, or burn the Folder(after editing) again with ImBurn to a regular disk (to save cost) which will play on the PS3.
I guess you could see how it looks on your HDtv and go from there with the exporting, but I have been happy with the way I do it (which I copied off various other guys particularly at the cineform forum).
Why are you using After Effects to encode?
I'd like to know how it goes so I could learn something also.
Thanks,
John

Until I actually get my hands on a BD-RE (my town has exactly zero specimens anywhere), I need a way of mounting my test ISOs to see if they've ended up being low-res like Encore's preview window. Daemon Tools fails. I don't know what else to use. I've got the trial version of PowerDVD ready to go.

3.45 hours is a lot of video for a single dvd, even a DVD9. Depending on the noise level present in the original video, the results could be horrid.

Having said that, I personally have not yet created a disc with Encore. I know enough about it now to realize that the moment there's an alternative, I'll be using something else to develop Blu-ray discs. But for regular DVDs, I've always used the combination of Nero and some authoring program.. usually DVD Lab for its quick and relatively painless building options.
