I was going to mention Ben’s Projection script but I forgot!
Sorry Ben 😉

Looks like a good V3 Walter. Let’s see if we can improve it a bit more. I’ll revert to you offline.

Post script or Expression Qs in the COW’s AE Expressions Forum – https://forums.creativecow.net/adobe_after_effects_expressions. You’re more likely to get a quicker response over there.

When you apply the mocha Shape are you selecting a layer in AE and then (1) pasting via CTRL+V or (2) selecting Paste mocha Mask from the Edit menu?

I suggest that you go the (1) route. When you export shapes in mocha, you will have options on which shapes to export. If you choose ALL or Selected, these will be pasted onto a single layer in AE.

If things still aren’t working as expected then take a snapshot of (1) your mocha layer stack (2) AE Timeline – ensure that you clearly show what you’ve pasted from mocha and (3) Comp Panel.

When pasting mocha Shapes in AE, YOU ALWAYS paste them when the CTI is on the first frame of the comp in AE. This is the case regardless if the layer in mocha have different in-out points if you had set these differently from the source clip, in mocha.

[Ridley Walker] “Just discovered that Dan Ebberts solved the problem in the Expressions forum, it seems that the length of the Composition was a factor.”

Is this the same thread that Dan posted – https://forums.creativecow.net/thread/227/19701 ?

Did you really export Transform data from mocha or was it Corner Pin data?

[Walter Soyka] “I’m working on a couple of fixes — I think I’ve got an even more accurate solution for scale now.”

Awesome! And I think I may have found a robust solution for Orientation – which was actually so ridiculously obvious. lol

I’ll drop you an email shortly. In the meantime, please download those two files that I mentioned in the previous post – it’ll give us proper references to with.

Hi Walter, I’ve played a bit with your script. It looks promising but needs more tweaking.

The Scale Expression seems to be more accurate with this script –

refTime = framesToTime(effect("Reference Frame")("Slider"));
//distance = length(sub(position.valueAtTime(refTime)[2], thisComp.activeCamera.position.valueAtTime(refTime)[2]));

distance = length(sub(position.valueAtTime(refTime), thisComp.activeCamera.position.valueAtTime(refTime)));
scale * (distance / thisComp.activeCamera.zoom.valueAtTime(refTime))

I’ve essentially removed references to [2] in the position array. I believe this provides a more accurate result.

The refTime variable is a good feature that you added. There’s still more testing to be done as I’m still having issues with the AnchorPoint location

I’ve been testing with these two clips, Blaster Walk HD and Survey Shot HD from here https://www.hollywoodcamerawork.us/trackingplates.html

While testing, it is important that the freeze frame/clean plate is created on the frame where the insert area provides itself at its highest rez. This precludes the first frame on a fair number of shots.

I intend to test on the 1st, last and a few frames in the middle. The z-position of the area/object to be removed is also crucial since the higher rez requires more accuracy.

Also important, it seems, is the type of camera movement – things get tricky with larger camera moves. Hence, it’s best to test on footage with large camera moves.

I think the issue is with the tracking results rather than the mask. I suggest that you use mochaAE for the tracking. Then export Corner Pin data from mochaAE. You will also want to export out Shape Data from mochaAE, to be used to outline the shape of the mirror.
