Premiere Pro Renders Warning Banners...Why?

That warning was there because the effect did not complete it's work properly, and so would not have been applied properly.

All I did was add a dip to black which triggered the warning banner but I knew there wasn't going to be an issue as the tracking data was still the same, hence ignoring the banners.

Um ... that's not how it works. If anything is changed, it needs to re-analyze. If you close & reopen the program, it will re-analyze. It doesn't know the data is still the same. I've seen a long explanation by one of the engineers that deals with WS on why this is so, but I don't remember the whole thing nor probably do you want to read the page or two of information.

So, that was basically an understandable user error based on a very understandable guess at how it should work. Frustrating and painful, been there done that. But to avoid this in the future ... one needs to work within how the program does work, not how we think it works, or should work.

Then work just gets done.

As this is a user-to-user forum and not one that the development team monitors completely, for the suggestions you make file a bug/feature request form. They never reply, but every one filed goes into their collated system and is delivered to all managerial types.
