My effect computes values from all frames in a layer much like Warp Stabilizer does. I set a flag and do this when necessary in my Render function. The user controls when to analyze by clicking a button in the effect UI.
It can take from a few seconds to over a minute depending on the layer, so I need to show progress to the user.
In After Effects I can use the progress bar, and put text in the info panel from within the Render proc; but I'd like to find a better way to show progress.
Indicidentally, neither of these two thing seem to works in Premiere Pro.
Warp Stabilizer shows progress to the left of the Analyze button in its effects window, but I can's seem to do this from within Render.
Any ideas?
