In premiere pro can an effect (mosaic) be applied to an adjustment layer using Automation Blocks?

[jeremyd80264819]

I want automation blocks to bring in an adjustment layer, and apply the mosaic effect with a mask already set.  I can get the adjustment layer to work, is there any way to apply an effect with automation blocks?

Hi Jeremy,

unfortunately, the scripting engine of Pr cannot apply effects, yet, therefore Automation Blocks also cannot do it. I am sorry, but I don't know of any workaround for that (except for using Ae instead of Pr - in Ae you can apply effects and presets with Automation Blocks easily).

Is there any way to execute separate .jsx file within automation blocks? 
I found this video on yt where the author applies effect with the script he made, I'm quite new to this, but how is this different to automation blocks? 

[Mathias Moehl]

Wow, this is very interesting! I was not aware that this is possible.

The tutorial uses functions from the qe dom. This is a part of the scripting engine, which is not documented and only indended to be used by Adobe internally. This also means, there is no support for those and they could in principle break any time. But very exciting to see that it is possible. I just added a note about this on my todo list - maybe I should support adding effects using that method, too.

Currently, executing custom extendscript code is not possible, yet, but I have it on my feature request list already. Could happen that this will be added in the next few month.

Hey, that's sweet. Thanks for the reply

Today we published an update of Automation Blocks, which includes a block to execute arbitrary jsx code. 

You can use this now also to execute the qe dom code you found to apply effects to clips.

See here:

This is amazing, I'll be using that. Thanks Mathias

Hi, this is cool feature, but i cant figute out how to path myclip into this script.  Please explain.

[Mathias Moehl]

Here is some sample code, which extracts from a clip its track index and clip index:

I added this example now to the Community Library at

Code Snippets/Sequence Clips/Extract Clip Index and Track Index from Clip.xml

How it works:

In Automation Blocks, the clip is represented as a path text which contains the track index and clip index at the end. The execute code blocks parse the path text with a regular expression and return the extracted parts.

[Alex Zippen]

Thank you for your answer. This script gives clip index without consider freespaces beetwin clips.
Script that apply effects need clip index with freespaces considered. For 3rd clip it return clip index 3, but effects will apply to 2nd clip as there is a freespace, that counts as 2. Is it possible to get clip index with freespaces considered?

[Mathias Moehl]

Oh, yes, you are right. The QeDom counts gaps as clips, too...

Try this one - the idea is to loop over all clips until we found the clip we are interested in. On that way, we count both the clips and the gaps between them:
