You probably hit F10 — your comp view is set to Front. That’s an orthographic view that does not show perspective changes.

Change it back to Active Camera, either with the UI control in the comp viewer panel, or by pressing F12.

Can you post a screenshot that shows the problem and your entire UI?

I think they’re stored as embedded XMP metadata.

If you’re trying to access the data via Ae scripting, you should just be able to step through the markers. If you’re trying to access the data outside of Ae, maybe the XMP SDK will help you:

A lot of systems use uncompressed AVI, but again, it can be risky to assume.

And to clarify what it does… autoFixExpressions(oldText, newText) will identify all broken expressions, do a search and replace within them (swapping out oldText for newText), and committing that change if it fixes the break.

Different systems can have different requirements. You should confirm delivery specs with the venue.

Try it like this:

var originalCompName = "Comp B";
var newCompName = "Comp C";

myComp.name = newCompName;
app.project.autoFixExpressions(originalCompName, newCompName);

Use rd: Render Layers as you normally would, but choose “Queue Only” instead of “Render.” Then, in the render queue, click the “Queue in AME” button instead of the “Render” button.

Alternately, if you want to encode MP4 directly from Ae, pick up a license of AfterCodecs from Aescripts.

My studio is cross-platform — some of us are on PCs, some of us are on Macs — and we share files back and forth all the time.

There are two gotchas.

1) Using your pinky for Ctrl instead of your thumb for Cmd. This takes a little getting used to.

2) You can’t render Apple ProRes on a PC (without a third-party workaround, like AfterCodecs). We usually use CineForm for our intermediates, as it’s natively supported in Creative Cloud applications and it’s cross-platform.

Your layers are all guide layers — meaning they are visible in the viewer for the comp they are in, but they will not render on output or when precomposed. This is a great feature when you use it intentionally to bring some kind of reference into a comp, but it can be quite confusing if you’ve set them accidentally!

To fix your issue, select your horse layers, then from the Layer menu, toggle “Guide Layer.” They will now render normally.
