How to remove 10Hz video brightness flicker in Pro 14?

I did the usual thing of shooting with a phone which can do only 60fps (Samsung S7) under 50Hz fluorescent lighting.

Is there a plug-in in Vegas which can remove this? I can't find one and nothing turns up in google.

One interesting suggestion was to set video track opacity to 50%, create a copy of the track on another track, shift this second track along by 50ms (half of the flicker period) and render the lot :)

The plugin I use for getting rid of - or reducing - fluro flicker (25/50 fps under 60 Hz fluro) is the Flicker Fixer plugin from the Image Restoration Unit of Boris FX's Continuum OFX package. The downside is that individual Continuum Units (or Continuum Complete which has all the units) is, depending on your budget, expensive. But if you're going to need to fix fluro flicker regularly, it might be worth it in the long run.

Thank you... yes, very expensive!

BTW, the video is here

A much better solution would be to use a halogen lamp, or shoot at 50fps :) I have a Canon G40 50fps cam which would also do a much better job.

nothing turns up in google.

I don’t use Google, I use Start Page, and it gave me a lot of results. I clicked on the first, and it led me to this video:

That, in turn pointed me to Flicker Free Plugin by Digital Anarchy. It alleges to work in Vegas and to have a demo version, so you can try it. It costs $149.

No method using anything in Vegas? I have some NewblueFX and Mercalli plug-ins.

I did try the method I mentioned above (offsetting a second video track) but it does nothing. I reckon it does not work for a light source which is pulsed with a narrow pulse, because you are just shifting that pulse along a bit. It would equally not work with LED sources because they have a very sharp risetime (microseconds).

If you're willing to repair your media outside of Vegas, you might look at the programs that timelapse shooters use to deflicker their source media.
