  • Unusual Anamorphic — 864×486 1.778 aspect ratio?

    Hi Cows,
    Was hoping someone could shed some light on a few questions I’m having on this project.

    I am receiving 3D files at 864×486 pixels with a 1:778 pixel aspect which I will be performing a conform with (eye matched to an Avid edit at SD.) AE doesn’t have a canned aspect of 1.778 and I may need to re-aspect some SD footage.

    Since I’m getting the files at the correct (and somewhat bizarre) aspect with square pixels, so in AE I need do nothing with that footage. However, I will also be mixing in SD (720×486, .9 aspect)footage with these other rendered files. Is there a simple formula to properly aspect SD (.9) to this 1.778 anamorphic aspect ratio using percents or another method?

    I suspect I’ll receive more info on whether the client will want a letter box for SD footage or fit-to-fill with some cropping. Does this sound familiar to anyone? Not to mention the problems of fields from the SD… that’s for another day as I can’t ask for a reshoot in prog-scan.

    This peice is going to a trade show and will likely be fed to multi-sync screens from a PC. Thus the somewhat unfamiliar specs.

    Also, the client wants the final .tga sequence rendered from AE specified as 96 ppi. I thought that request was unorthidox as well (what is an “inch” on a TV!?) Is there a way to augment my output specs to include the 96 ppi from within AEs output modules or with an output plug-in? Or do I need to batch to that spec from an “Actions” script in Photoshop (remember Debabelizer?)

    Any help or tips would be greatly appreciated. The project is slated to start in 2 days for my end of the work and the project has many layers and ‘over’ clients, as in an onion…

    Thanks a lot for taking the time to post.

    Actually, I found some info that clarified this a bit.

    1.778:1 is the same as standard anamorphic aspect, or 16:9. Havn’t heard the “1.778 aspect” in a conversation in a long time (if ever).

    Well, hopefully this may help someone else! I fell a bit, er, embarassed to have bothered you all now!

    For the SD footage, Ill just need to place it in a 16:9 comp and place it into the custom 846×486 conform comp. The fields issue, I’m hoping will not be an issue and the footage was acquired with prog-scan. I’m a bit too far down the production chain for THAT to be the mistake it probably will be…

    Still, is there a way to output that 96 ppi from within AE?

    Thanks!

    You can’t output 96 ppi from AE. A pixel is a pixel as far as it’s concerned.

    You can try doing a batch action on the tga sequence in Photoshop to save at the same frame size, but at 96 ppi, but I think your client is making one of those “I want to sound like I know what I’m doing” requests.

    My 2 cents,
    Steve

    If you’re on a MAC Graphicconverter does a much faster DPI setting batch.
    But I agree it’s an Italian Sausage request (I don’t know how to spell balony ?)

    the 72 vs 96 dpi is a Mac vs PC issue that affects fontsizes on the web, so maybe the boss thinks that the video will look too small on a PC or something like that.
