Anyone using After Effects successfully?

Hi everyone,

I'm having trouble rendering in After Effects. My finished clips alias horribly. I can render out of Final Cut Pro fine.

I'm capturing via Final Cut Pro with it's HDV preset, 24 frames a second. It converts the clips into an uncompressed quicktime. No problems there.

But in after effects 6.5 there is no HDV preset (7.0 has one) When I make a composition out of the clip it gives me the following parameters.

1920x1080
1.33:1 Non-square Pixel Aspect Ratio
frame rate: 23.976

and when I render I don't change the frame rate or size. Nor do I interlace, I render in frames.

My final renders have aliasing problems on all vertical lines within the scene.

Any ideas? ...thanks

Win

After effects

I had the same issue for a while. It makes a big difference how and where you do your conversion.My best results, after a lot of exporting and checking frame on frame results was the following:

-capture with fcp your hdv 24p (DVHSCAP is also great but no log)
-convert to AIC or dvcpro or whatever using compressor (you can batch and it keeps timecode, mpgstreamclip won't)
- use that converted file in after effects (it usually interprets the footage as interlaced, you have to go into interpret footage and change that)
-Render using the same codec (I use aic and make sure to chose the progressive and 24p)

sadly ive not used fcp + afx together as im a pc man

BUT

in after effects i always use

1920x1080 SQUARE pixels
24fps

and if the footage is interlaced make sure you select UPPER fields first

Best of luck
