Need a working mgjson file for "align video to data" feature - static timecode info in MGJSON

Hi there,

Im trying to use the "align video to data" feature in AE that is documented in "Data driven animation".

Unfortunatelly the documentation is not enough to build a working mgjson file for this case.

I found an CSV to mgjson file converter but that seems to be for dynamic sensoric data only and not for static timecode per layer data.

In the Sensoric Management SDK documentation its mentioned how someone would build such an mgjson file but Im no programmer so Im a bit overwhelmed by all that information.

Does anyone ever succesfully used the "align video to data" feature or created an mgjson for static data?

Would save me a lot of time as I need to set hundreds of layers on specific timecodes and also put keyframes on them...

mgJSON is a bit of a dark art honestly, but I don't believe it's going to do what you're asking anways. It will only move the listed video source(s) to align with the data layer so that referencing the data layer will sync with the video.

You should probably look into scripting to automate your taks, but that's programming.

Ah I understand, yeah, my case is probably a bit special.
I have about 100 Layers per Comp, and around 6 comps(so around 600 layers) that I need to put on a Timecode thats written down in a sheet. (Director needs specific timings for all of these thats why..)
My CSV kinda looks like this [Layername | Text | Timecode] and used with a json file I automated the text for example.

My take now was that I can align these layers to the timecode in the sheet with the "align video to data" - and thats where my mgjson rabbit hole began haha

But thanks to your link I just found "Layer.inPoint" that I could probably combine with my normal json file. So far my I took my expressions from tutorials and only changed them slightly but this is probably worth to check out. I'll take a look if this does what I believe it does. Thanks for redirecting! I wil check that out this evening.

This is the part Im talking about - see Image

Problem is MGJSON files need a bunch of code in the beginning before the code in the documentation is working (or it even lets me import to AE) and this is the problem I face as Im no programmer and its a lot of information that needs to go before the data itself...
