Blurring static objects in the part of the timeline

PostWed Jun 02, 2021 2:41 pm

Hi Folks,

I hope you are well.
I am new to DaVinci so forgive me if I ask obvious to some of you guys questions.
So lets's get started....
There is a timeline I would like to partly blur: someone has putted a static object while recording that can not be included.
I know how to blur it but have been struggling to apply it to only to the 10 seconds of the footage.
Many thanks in advance and look forward to hearing from you,

Kind regards,

Simply keyframe the blur.
No, an iGPU is not enough, and you can't use HEVC 10 bit 4:2:2 in the free version.

If it's an individual object, I think you'd have to put a power window over the object, track it, and then blur it as Uli says above. The trick is not making it ugly or noticeable.

If you're willing to spend time and money, I bet it'd be possible for a VFX artist to go in and roto out the object completely and replace it with the background. But it's likely it would not be cheap or easy. I have worked on TV versions of feature films where they had to go in and put "digital clothes" on naked people, remove bloodstains, and even remove guns when they felt they were too threatening. Famously, Spielberg removed the guns from federal agent hands in one of the 1990s versions of E.T., but he later regretted it and has since said he would never again alter any of his films with any revisions like that, no matter how well-intended the change was.

And the better tool for that would be Mocha.
I once had to use it to make a dog disappear which crossed the stage in an open air ritual dance event.

That would definitely be a challenge! The tools within Resolve are pretty good (for free), but Mocha is a much more-sophisticated solution.
