LED Light Flickering Fixed (VP18-482)

For literally years(!), I've been trying to figure out a way to fix a video that I shot in 2015 that yielded a flickering LED light directly behind the moving presenter. He walked left and right across the flickering light, so it was almost impossible to use other techniques to disguise or fix it other than to use some tricks to dim at area. But that resulted in changing the presenter's video quality and look. BUT, VP18-482 fixes it when I use the Media FX with the Flicker plug-in and the Flicker Reduction Preset setting. YAY! There is absolutely no flicker motion at all except a very small amount of shimmer when I moved my camera left and right. I am very pleased. The LED light is the kind that can change colors and dimness, so that may be the reason that it flickered in the first place. Their handheld light remote control system may have a weird non-standard frequency.

Cheap LED lights do that... they pulse 60 times per second, and if your shutter speed and frame rate are not in sync, they'll see the shut-offs between pulses. More expensive LEDs have drivers that pulse them much faster than that, so they play nice on camera.

In 2015 if you had tried Digital Anarchy Flicker free plugin for Vegas Pro, that issue of yours would have been completely fixed in seconds (smile).... You also had RevisionFX DE:Flicker as another option.

It's a year later and the light flicker is fixed. HOWEVER, when the talent moves quickly left and right or moves arms, etc., there is blurring of just the talent when using the Flicker plug-in. This is caused by the Flicker plug-in itself. So it helps the flickering light but caused blurring of the talent. Just as long as the talent doesn't move much, the talent and the light are perfect with no flicker. (I have several video productions from that era when I had the shutter speed problem.) I've tried every combination for the Flicker plug-in, currently in VEGAS Pro 19 550. Any ideas? Would edit and/or rendering at 60fps help? Sharpen plug-in? Any other ideas?

@RonB_USA  Hi what about adding a mask, both Pan/Crop & Bezier masks will 'Apply to FX' only?

PS. Pan/Crop mask you can keyframe

It's the same with camera movement as well. A slowish panning shot I had a while ago ended up with a disappointing amount of blur with BCC Flicker Fixer applied to the video event to reduce flicker from ceiling fluro lighting.
