I will be releasing these as part of NANY 2022:

Code is now available on github: https://github.com/dcmouser/jrPremiere



Some of you know I've gone pretty far down the rabbit hole of video editing for my latest project, a Boardgame YouTube channel (see this thread).

I've actually spent a lot of time creating custom After Effects (motion graphic) scripts and templates for the channel, to speed up the process of creating nice looking edits and overlays.

This week I decided to learn how to code an Adobe Premiere extension, to automate the generation of YouTube timestamps and to make it easier to navigate around the interesting parts of nested sequences.

Here's a teaser screenshot of my extension called "TimeStamper":

From the README:

Scans your active sequence and builds a timestamp list of "notable" clips and mogrt item times in your active sequence.
Mogrt items are listed with text field values.
The timestamp list is presented on the extension panel as a clickable list to quickly jump to locations.
The timestamp list is exported to a timestamp text file in your project directory in YouTube timestamp format, for easy copy+paste into a YouTube video description to provice clickable timestamp links for your video.

And my second extension, again designed to automate another thing I do a LOT of in my editing, "SoundFxAdder":

It scans a sequence looking for mogrts, graphic still images, or text overlays (which some options for filtering them based on type, etc.), and then can insert an AudioClip synchronized to them.

This is something I have been doing by hand to give a little "bloop" sound whenever something interesting is editing on screen.

Will work in batch mode or show you a list and let you jump around and individually add with a click, and features some safety checking to make sure you don't overwrite some existing audio.

Another extension coded:
Multicam Deluxe

This one is a doozy -- it automates the elaborate process I use to turn dual (multi) camera footage into a sequence with a 3rd virtual camera angle that is top down with a small front inset picture-in-picture, and some other helper stuff for that.

Another extension coded:
CFT

Automates the process of inserting a freeze-frame retro-style intro:

Plus does a few more things that I commonly do, to make editing my videos easier.  Like saving an increasing version# in the file, exporting thumbnail images, rendering for youtube with the project filename, etc.

[UPDATED 10/15/21]
Updated screenshot to show a couple more new items added to this extension:
  • A censor-bleep action that adds keyframes to drop the volume around the playhead, and add a mogrt that plays a beep sound and shows a censor bar over the person's mouth.
  • And a simple action that applies a sound fx processing to the audio clips that I use for sound reduction if I record with A/C running.

A minor new extension coded:
Preflight

"This extension helps facilitate doing manual preflight checks of your sequence to look for problems.
Scans the active sequence according to your options and makes a list of timestamps of potentially interesting items, that you can easily jump to and select.
In essence, this extension reuses the code from my Timestamper extension but with it's own independent options to make it easier for you to configure it to list only timeline objects that are important to you.
The list of timeline events makes it easier to jump around and check for any problems.
For example, I find that I occasionally have mistakes in my multicamera edits where I zoom in on a clip and erroneously switch to a different camera; I can use the Preflight extension to find all clips with special effects (including zooms), and then rapidly select them each in turn to check that they are correct.
Pressing the preview POI button will jump to the next interesting timestamp in the list and play a section around this timestamp.  Or hit "Preview all" to have it play through each point of interest in order.  In this way you can very quickly preview all of the transitions, mogrts, etc. without having to rewatch the entire video.
"

PS I not a youtuber, and have never used Premiere

If anyone here is a Premiere user on an apple mac product, drop me a message --- it would be nice to test out these tools on that platform.

Another small one, ZoomKeys:
Screenshot.pngAdobe Premiere Extension coding: TimeStamper, Multicam Deluxe, SoundFx Adder, et

Simple extension that takes a clip that has a static scale/position setting, and animates some keyframes for the clip based on those values.  It can create a pleasant zoom-in, zoom-out, or combination.
Normally when I have the mental energy I will create such an effect myself when I want to show in a zoomed-in area, but more often I get lazy and just cut to a zoomed-in view.  So this automates that process.

note: it currently does not support easing, since that API is not working for the current Adobe Premiere.

Edited the above posts to add (draft) videos for each extension to show how they work and how to use them.

My plan is to open source them all for NANY 2022.

I will have to decide before then if these videos are good enough or if it's worth the time and effort to remake them.

Just a little warning: My MulticamDeluxe extension makes use of the awesome FeatheredCrop plugin for Adobe Premiere (https://www.creative....com/feathered-crop/), but that plugin seems to have been broken with the latest Premiere release.
I may add a workaround that will crop using built-in crop filter in Adobe premiere (but without the nice border provided by FeatheredCrop) in the near future.
Hopefully they will fix it soon.

Minor update to my extensions posted to github to better let you filter out MOGRT from normal video clips in the TimeStamper and SoundFxAdder extensions.
