ok… when you go to Make Movie, and the render queue shows up, there is a listing for Render Settings and one for Output Module
Click the word Best Settings and check everything out there, make sure it’s all the way you want it. You probably don’t need to change anything, but just check it out if you want to.
Then click the word Lossless.
If the format is AVI, then click the Format Options button under Video Output.
Change the compression type to something that actually compresses the video. Set your quality settings and everything up, then hit okay.
Hit Ok at the bottom, then hit Render.
that’s about all you need to know. The choice of compression codec is entirely up to you can what the photo frame thingy will suppoort.

you’re probably rendering this as an uncompressed video file.
You need to choose an output module or at least change the default render settings to something that compresses the file size somewhat.

If you’re using non-temporal footage (like mpg, h.264 and possibly the MP4 footage you speak of), this will cause all kinds of weirdness in After Effects, as it doesn’t contain complete video frame data. These codecs throw away information that AE needs to work properly.
If you’re lucky enough to be able to convert it using After Effects to a codec/format that contains all video frame data necessary for AE to use, which it seems like that’s the case from your post, then you already have your solution.
Many people have to convert the footage before they can even use it in AE to output any files at all.

Decklink says it does what you want it to do.
We just hooked up a Decklink SP today, but I haven’t had a chance to test AE with it.
good luck.

I think using gradient wipe with a set of footprints that are colored from white to black, and each is a darker value of grey for each step will do the effect that you want. It will be a pain to set up, I’d imagine, but you can have up to 255 shades of grey I believe, so that would make the number of footprints available for the effect work out. You can vary the length of the effect, and size of the footprints, and layer them so that you have many more than the initial set up.
Just put a black layer as the background, and it should work out. You might have to precomp the footprints layers…
There may be a simpler way… I’m still figuring it out.

have you tried the Simple Choker or Matt Choker effects? I used this once to get rid of the slight edge left from a premultiplied shadow next to a transparency.
see if it works.
Also, check out spill suppressor under keying in the effects menu. That’s what it’s for.
-
just know that if you do use the wrong codec, you won’t be able to import and use that resulting footage in After Effects without first converting it to a non-temporal codec. Things like mpg and h.264 toss out keyframe info that AFX requires to render out a movie.
-
There is a plugin from Trapcode called Echospace. This can achieve the effect you’re looking for, but there may be a simpler, cheaper solution.
check out Echospace anyway… it’s pretty cool, if a bit limited in scope.

what output module are you using to render it?

You need to convert your footage to something with a non-temporal codec. You will have to do this outside of After Effects, then import the result.
The following is stolen from Dave…
Dave’s Stock Answer #1:
If the footage you imported into AE is any kind of the following — Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 — you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
