You can upload stills here. It might be easier for everyone to offer a solution if we had a better idea of the problem areas.

We’ve experienced some similiar problems using QT references at our facility also. While we haven’t figured out exactly what is causing it(doesn’t happen every time), we’ve discovered that by doing a video mixdown first and exporting that, the QT references get all the information needed.

An easy way would be to just add an adjustment layer. Add a levels effet and crush your blacks a bit. Then add a Tritone effect and change the midtones to a deep red. When you want to “pause” just change the opacity of your adjustment layer from 0% to 100%.

Add a wiggle to one of the layers and then parent the 2nd layer to the first.

Not really sure Mocha is going to work, unless you are are going to loosely cut the guy out with a mask and have the mask follow the track.

Unfortunately, to do this effect you need to cut the guy out. One way to do that is by using masks and animating them. Start with one for the head. Mask shape in the middle of your clip and keyframe. Go to the beginning and keframe. Now split the difference. Keep splitting the differnence until the mask follows the head. Repeat for torso, legs, arms, ball. Now you composite that over a desaturated version of the entire video.

You could use a very loose mask(feathered), if the action is fast enough, camera movement, might work.

Finally you will want to check out the rotobrush. It’s advanced and you will definetly want to check out the tutorials at adobe.com.

Thanks Brian. I’ll give that a try.

I’m really kind of stumped with this, not a big deal, easy to work around it, but still puzzling.

You should be able to scrub the parameter, depending on your graphic card will determine how quick it updates.

In your composition window make sure the live update button in pressed. 2nd one from the left above the timeline.

No video though, just 7 solids, some animating masks, a null, and an adjustment layer with channel blur.

For fun I rendered out my BKG without channel blur, brought it back into AE, applied channel blur and it worked fine.

Obviously, I can work around the issue. I’m more curious as to what is causing the issue.

Uploaded the project, if anyone wants to take a whack at figuring this out:

Look forward to seeing how you accomplished that.
