Sir_Ivan , thanks for your reply Sir Ivan.
I want to say "general funkyness"... or perhaps there are some PEBCAK issues in there, or miscomprehension of some features, but here goes.
This morning, Labels seem to work, but on and off... Select a clip in sequence > call up Label color change > select color > Enter... nothing on the 1st attempt. On the second attempt, I selected a source clip in the project panel and did the same; the label change did not occur on the selected source, but rather on the previous selection in the sequence... On the 3rd attempt, with nothing selected in the sequence, again selecting a clip in project panel and calling out the Label change, nothing happens; but Premiere's focus (e.g. the blue outline) has switched from Project Panel to Sequence Panel -- so I assume this tool is meant to be used in sequence only? But then why does it only seldom work if that's the case...
I recall having built a really powerful macro that was doing a bunch of operations from matching, reverse matching, replacing shots, etc., that worked beautifully but would also stop working and do undesired moves in the process with improper selections and stuff. One other thing that often did not work for me were introducing delays in such macros. Again, it's been over a year that I more or less left this app on the sidelines now so I haven't tested that since then.
Not working this morning:
Show Clip Keyframes when there is no keyframe, but I tried it again after adding a Scale keyframe, and the option of going to viewing Scale works, but you can't go back to position or Opacity for example if they are on their Default values... Bug? Tried it with the keyboard's up/down keys + "Enter" as well as with the mouse/pointer... I did get it once to go to "Position" kfs even though they were on Default, but that was once in 5 attempts.
Undo does not always undo what Excalibur just did... Not sure if that is normal or not (I know, I should read your doc.).
Working:
The Sequence Duplicator + Archive; solo/lock/mute tracks, and a few others that I tried out of the blue.
Of course, things are not so bad this morning now that I want to report all the issues, LOL... But I sware, there are days where nothing works basically, I try 2 or 3 functions and when I see they don't work, I just forget your wonderful app.
In terms of installed Extensions, unsure if you only want to know Excalibur's or others, but here's the complete listing: Anchor, Arrow, Grave Robber, Beat Edit / Quick Importer / Still Exporter, LogiOptions+ (Logitech), PowerSearch / Transcriptive Rough Cutter and finally Text Replacer.
Let me know if you need more info or what I should be doing next. Catching up on all the gems in this app., I'd really like to have it back in my arsenal!
Best, --Alain
