I have to stitch various pieces of footage together, and the final result will be about 1–1.5 hour long.
Because of all the needed changes (blurring faces, inserting images and icons in certain places, synchronising the footage pieces among each other and fading them out\in with right timings etc), my project map starts to look like this. The #3 and #4 tracks are just transitions from one piece to another. In tracks #1 and #2 is how most tutorials tell to deal with blurring\changing a screen area (duplicate the track above itself and then pan\crop the duplicate).
The problem is that in multiple places the video also has to be sped up\slowed down, and when I do it, the footage length changes like a fractal curve, and all the alignments get messed up. And besides these speed changes, the whole eventual video has to be sped up again once more too (x1.5).
This looks like one of those things that I’ll be cursing myself about later, because a simple and overlooked mistake led to losing huge amounts of time\work, so I decided to just ask about it now: am I doing it wrong, and if so—what’s the more productive way of dealing with many playback speed changes in relatively big editing projects?
