Easy way of editing keyframes in adobe Premiere
Adjusting the default video transition duration

Go to Preferences -&gt; General and change the Video Transition Default Duration to a frame amount of your choice.

Optimising current workflow

I can think of some optimalisations regarding your current workflow. It's not a drastic change, but might help you do the task faster.


I would suggest splitting the timecode list per videotrack (slide &amp; stage) according to the following scheme:

List 1: slide fade-outs
List 2: slide fade-ins
List 3: stage fade-outs
List 4: stage fade-ins  

List 1 should match list 4 and list 2 should match list 3.
Go to the first fade-out on a list. Create a keyframe pattern you like for the fade-out, for example the one shown below:



In the effects panel it looks like this:


A linear keyframe followed by a bezier keyframe followd by a hold keyframe.


Now select those three keyframes in the effect panel by dragging a rectangle around them or clicking each keyframe while holding ctrl (Windows) cmd (Mac).
Right click and press Copy
Now go to each fade-out timecode on both video tracks (so list 1 and 3) and in the effects panel right click and press Paste. Of course you can also hit ctrl+V or cmd+V.
Repeat this process for list 2 and 4.


In this way you only have to set the bezier speed once and just copy paste the keyframe sequence at each timecode.

Exporting keyframe locations to textfile

I'm not aware of a way to do this directly, but if you export your project to a Final Cut Pro XML or to EDL (Select sequence, then: File -&gt; Export) you have the ability to change the position of /add keyframes through a text editor by editing the .edl or .xml files . You can then import the .edl or .xml file into Premiere Pro as a new sequence.
However, these formats do not support bezier keyframes.
