How do I remove a moving object in Video Paint?

Post by Owen »

I use video paint often as it is one of the features that drew me to MSP several years ago. Premiere and the other low end editors never had this feature.

I have removed objects from a scene very sucessfully many times but always on a camera locked off shot. eg. A persons shadow moving across the frame, light stand on edge of frame. a wasp flying through the shot, onlookers moving into shot, to name a few. All these were accepted for broadcast and no one has ever noticed the patch up job.

How do I achieve a suitable result on a panning, zooming, or camera movement shot? I paint the first frame out successfully. The problem is when trying to copy the repair to the following frames the object to be hidden has changed it's relevant position in the frame. You would think it a simple proceedure to drag the floating 'patch' to cover the offending object. In reality it never positions correctly giving the illusion that the patch is vibrating during play back, drawing attention to it.

I have shot a music video and there is a van parked in the background that looks ugly on a couple of scenes, all on camera following shots. I would really like to cut the van out of the scene to an acceptable level to broadcast.

Can I do this in VP? Or do I need another programme?"

Owen,
It can be done in MSP's Video Paint module. But none the less rotoscoping is very time consuming. As you stated "locked on" shots are much easier. When movement is involved, I tend to use a 3D program to create a mask and key its movements over the video and then use it later in my editor's overlay options. If using VP, watch your coordinates so you keep the proper alignment frame by frame, otherwise you'll end up with a staggering output.

Here's some samples for you.
Sample 1: Used VP to paint out left side to composite my 3D animation over background video. Also, in your case with the van, you may want to use creative editing techniques to draw your viewer's attention away from it. Examples: Use Pan & Zoom filter, Crop it out and use Picture in Picture, etc.

Sample 2: Used COOL3D PS and video as background. Created binocular-shaped 3D object and keyframed its movement over engines, while changing its size accordingly for added depth. Then used MSP's waterflow filter and overlay options to finish the effect.

Enjoy! and I hope this helps.

Much of the difficulty depends on the how much motion is happening.
If the camera is fairly steady, you can "paint" over the area you want to clean in the first frame, copy/paste the cleaned area over to the next frame, then just "nudge" the result left-right/ up/down to adjust for slight camera movement.

I did this to cover a bobcat lifter that was in the first shot of this DVD opener: http://www.jushhome.com/nick/media/nbbfintro.asp
If you look closely at the left side of the shot during the ice break, you'll see some of the "corrected" area that doesn't line up perfectly.
As noted above, having something (like some one breaking a ton of ice with his fist :p) to draw the viewer's attention away from the painted area helps. :)

Faster camera moves can sometimes be easier, since you can hide a lot in a blur, but it's more difficult if the camera is changing speeds.

Good luck.

Hi Nick,

Great clip. Say it gives me an idea. As a distraction I could have a fist knock the girls teeth out!!(':wink:')
Now then would that be right. She's pretty and singing about feelin so good. The fist would certainly be a distraction.(':D')


Great site you have. Thank you so much for all the info. I really appreciate it. Actually I've been using some of your audio filters for some time. Just the ticket thanks. I'm experimenting with your blue/green screen filters. I have a query but will try and make contact directly as I'll be getting off topic...

Cheers,
Owen.
