For my work I redact video using Premiere Pro. So basically I create masks using the mosaic effect and blur out faces and license plates, etc. Some of these videos are hours long and require many masks with many key frames on each mask. When I reach a certain level of keyframes/masks it slows Premiere Pro down significantly. I am trying to suggest my employer provide new computers but I am unsure what to suggest. I am not a tech wiz. What specs would be best to minimize the sluggishness when there are a lot of key frames on these videos? RAM? Processor?
You MIGHT want to look into Boris Continuum Complete...it comes with Mocha, and that will track a shape you draw, perfect for blurring. Something that would take me 2-3 hours to do, manual tracking, takes me...15 min? 20 min?
As for your tracking...why not render your blurs when done? Rendering them will then make PPRo reference that single render file, instead of gobbling resources to try to play back in RT.
