It’s the same issue with getting a Shape Layer’s mode – the pattern with the issue is when a Drop Menu occurs on the same and first line of the propertyGroup(). And the 3D Meshes too – the Mesh Options property.

IF I get back to it – moved on to other matters. My thoughts – since there isn’t an Expression to access it then the propertyGroup way would be the only option and you’re expert in this area. I’ll have to think of a roundabout way to do it OR file it away as “Unimportant”. 🙂

You need to set the timeline stack for a compositing task – see image below …

It’s going to take too long of a time for what I can offer now to post the AEP on my blog or at the COW. Hopefully the screen grab below provides enough clue for you to get productive OR DIG IN!!!

Hi David, looks like copying from the forum creates CURLY QUOTES in the expression instead of normal quotes. So, look at the expression in your Expression Textbox to see if there are any of these and change them to normal quotation marks.

Let me know how it does. I was going to drop an AEP and host it on my blog – may do it sooner than later but lots of things brewing over here. 😉

Mary, thanks for letting us know how you solved this issue.
Always good to hear when someone solves an issue on their own or with assistance from others.

Best Wishes

You can’t access composition settings to work automatically with a MoGRT.

If you need a MoGRT to be used in different frame sizes, frame rates and with interlacing, you have to set up the MoGRT accordingly in AE.

In AE, each ‘final’ composition is placed into a composition which will be exported as a MoGRT. In this composition, you create a Drop Menu for the user to select which nested composition they want to work with. You will link each nested composition’s opacity to the Drop Menu so that only 1 nested composition has Opacity = 100% from any selection. And this composition should also be the sized to the largest output requirement amongst the different outputs because Premiere will just display each MoGRT centrally.

It’s a bit cumbersome because you will have to link the text inputs centrally so that 1 change ripples through to all compositions. And this too for the Replacement Media.

Here’s the expression to apply to the brightness parameter for Lens Flare –

// Flare Brightness driven by pixels directly under the Flare Center point

// PLACE THIS EXPRESSION INTO THE Flare Brightness parameter

// Grab the Flare Center (2D point inside the effect)

flareCenter = effect(“Lens Flare”)(1); // change name if you use Optical Flares

// Convert that point from **effect point space** → **composition space**

samplePointComp = thisLayer.toComp(flareCenter);

// Target layer you want to sample (your video)

target = thisComp.layer(“mixkit-breakfast-at-a-table-with-bread-coffee-and-fruit-4866-full-hd.mp4”);

// Rect Size for sampleImage

rectSize = [120, 120];

sampled = target.sampleImage(samplePointComp, rectSize, false, time);

// converts captured RGB to brightness value which will then be used to drive the effect’s brightness value

luma = sampled[0]*0.299 + sampled[1]*0.587 + sampled[2]*0.114;

// Your desired brightness range – tweak these two numbers only

linear(luma, 0, 1, -35, 100)

You’ll need a Mask – I placed a mask over the plate. You will need to set the Flare effect’s Compositing Options to point to this mask.

This is where Mocha’s Unlink Tracking feature is useful.

Take a look at this tutorial – https://youtu.be/7UQcPRNKoiQ

TIP – Unfortunately, the green board doesn’t have a texture – so, draw a tracking spline to cover the left edge of the board and include parts outside of the board’s left edge. Hopefully, there isn’t any parallax to throw off the tracker and ensure the tracking spline area isn’t obscured.

sourceRectAtTime() expression method is the building block and the Null Points feature saves you one step. Also, look at purchasing scripts directly from developers – most have a store on Gumroad and purchasing directly from developers earns them a lot more than making a purchase from aescripts who make a 30%. So, help developers by purchasing directly from them. 🙂

Responsive Design Time in MoGRTs produces iffy/maybe/meh results, at times. This is my experience. Then, it’s designed for stretching only the head and tail of a MoGRT but what you’re trying to achieve is beyond the feature’s design.

An option is to deliver the MoGRT as part of a PPro Project file with a sequence set up with two copies of the MoGRT at the head and tail which the user can time stretch. For the middle section, you will have to look at using a Dynamic Linked AEP. It can get tricky but this is a bullet-proof option.
