Hi,

Please see the attached video for details. We are processing an outdoor dance performance video. Since it's not very easy to replace video background even with Motiong Tracking Mask in ColorDirector, would it be possible to clean background a bit? For example, the attached video shows a couple of people in background, someones sit (still subjects) and one walks (moving subject). Would it be possible to remove them or make them fuzzy in background?

Thanks & regards,
Lee

You can certainly mask out people and objects using BorisFX tools, although any motion there will require some keyframe work.

Alternately, you can try an inverse mask on one of the blurring FX to soften everything above and to the sides of the dancers. You can feather the edges of that mask to soften the change from focused content to blurred background.

Thank you for the information. Working with new tools is always fun but takes some time to get familiar with it. We start checking and see what BorisFX tool can do for our needs and how.

Not sure if PD has any functions we can use to mask/blur (still or moving) subjects in background? Wish it did.

Thanks & regards.

It depends a bit on how the remainder of the video is, e.g. whether the camera is moving (a lot) etc. but this is also a way of approach this:

make a screenshot of the video clip, look a bit at what frame the background is suitable

Open the screnshot in a photo-program like PhotoDirector and remove the unwanted persons and objects

Put the resulting image in track 1 on the time line

Put the video clip on track 2 on the time line

Open the mask designer for clip 2 and mask out everthing but the dancers in the foreground

Again, if the camera moves to much it may be more difficult, but have a look at the result given the clip you have uploaded (attached)

To remove moving objects there's a special tool called 'Hide' from Prodad: https://www.prodad.com/Video-editing-and-modification/HIDE-V1-86057,l-us.html

Thank you for the detailed procedure. It helps a lot.
