Trying to Render 720x486, but it won't work.

I'm sure this is something that is just part of CS5, but I can't figure out how to work around it.

I've mostly been working in HD here lately, but I had a D1 NTSC project to work on this past week, and every time I render a 720x486 comp it comes out 654x486. I've tried forcing it to render at 720x486 through the resize option, but that too is giving me a 654x486 file after rendering.

I've searched around for a solution, but haven't come up with anything.

Right now I'm using Quicktime Pro to resize it after it renders.

Anyone know if there's a way to force After Effects to render at 720x486 again?

Thanks,
Jason Moore

I can assure you that AE CS5 does render out to 720 x 486.

Pretty sure what's happening is you have are trying to work with SD at a 4x3 ratio, but you've inadverntly set the pixel aspect ratio to square. Change it to .91 and you should be good to go.

It sounds like you're using Quicktime to check the renders, and it's showing you the picture in 4x3, at the perceived H&V resolution for square pixels. If you dig around in QT, I think it will also show you the actual resolution.

Hmmm...

Well, the footage says it's .91, and I created all of the comps by dragging the clip over the comp icon, so it should be using the same specs as the clip.

I am checking the renders in Quicktime. It says:

Format Animation, 720 x 486 (654 x 486) Millions

Normal Size: 654 x 486
Current Size 654 x 486 (Actual)

I've never had this problem. All of my renders are coming out 654 x 486. I've been re-exporting using Quicktime to make them the correct size again.

Quicktime Player is lying to you.

Actually, Quicktime Player is converting from rectangular (video) pixels to square (computer) pixels on-the-fly, to ensure that your video looks proportionally correct on-screen.

If you re-import your footage into After Effects, or bring it into a compression application, you'll see that it is truly 720x486 with a 0.91 PAR. No need to adjust in QT.

You're right. Quicktime is lying. When I bring it back into AE it shows as 720x486.

I wonder why QT is lying to me all of a sudden. Maybe some kind of upgrade I applied.

The strange thing is that files I export from Quicktime appear the correct size when I reopen them in Quicktime.

Thanks for your post.

If you're running Macs, I highly recommend MediaInfo Mac for media file analysis/reporting. It's more informative (and less misleading) than Quicktime's Get Info.

I've got just the opposite problem. I was given two graphics by a client to import into an Avid Media Composer 5.0 project.

My artists normally give me 720x486 out of AE and that works fine.

One of the graphics the client gave me was 720x486 and it came into the Avid slightly anamorphic. The other was 654x486 and it was correct. They both look fine in QT.

I'm assuming it's a square vs non-square pixel setting in AE but I've never been super clear on what it should be.

What should I tell my client to do differently? I have to be diplomatic in this approach.

Any suggestions on what they/I should do differently?

Thanks,

Doug

Where are you reading the information for these resolutions: AE, Avid or QT?

I doubt you're using AE to create files for final use. You'll probably put your AE work in another application. So have you tried using these clips in this next application to see how they work?
