Can Magix Vegas make strobes look normal? [video contains strobing]

strobe lights in movies look same as seeing with eye but if you record with normal camera don't look normal. how do you make stroke look normal?

The strobe would need to be the same duration as your shutter speed, and synced to the shutter.

So the short answer is No.

You seem to indicate in previous posts that you have Vegas Pro 17, which again, is not a Sony product!

If this is the case, consider changing you topic title to reflect the correct brand, in consideration. Thanks.

Thankyou for your kind information. I remember seeing that it is possible to fix flicker when flicker is recorded due to some trick, I had hoped maybe the same is with strobe. I will see if it's possible to change subject, thanks

OMG 😮! That’s horrendous! You should really add a WARNING that this contains STROBING. Along the lines of: WARNING: CONTAINS STROBING

Ha! Ha! Ho! Ho! Nice one Grazie.

I seem to remember that, back in the day, NewBlue used to have a plug in that removed flash light intrusions on an event. It was pretty good as well but whether it could also deal with strobe lighting is anyone's guess. Might be worth a try if it's still available. Good luck.

@Richard Jones - Actually, RJ, I was being serious. As to “curing” the Strobe, it would deliver a series of staccato frames, and consequently almost as bad as the original strobe.

Boris Continuum has a plugin called 'Flicker Fixer' which can at best eliminate or at least reduce flicker created by situations such as fluorescent lighting, but I'm not sure how it will cope with strobing such as in your video.

The OP wants to make the strobe look normal. Can we clarify what is meant by a normal strobe or is the intention to completely remove the strobing?

Musicvid wrote on 2/2/2020, 5:01 AM

The place to add strobing or flash frames is in post.

Removing baked-in strobe lighting is impossible. Flicker implies a smaller order of magnitude, which may allow some correction.

What’s a normal camera?

What we're seeing here are the effects of the rolling shutter of the camera (combined with the asynchronous strobe starting always at a different segment of the frame beeing read out by the CMOS sensor). And there's an additional variation of strobe intensity throughout one strobe flash as can be seen in some flashes by the horizontal stripes/waves. But that's probably not meant by lenard-p. The problem is - as stated before - not called "flicker" and is not necessarily related to an "asynchronous" strobe, as those are almost always not synced to the camera.

Maybe there's a plugin to fix this. But it can be almost avoided by using a camera that tends to have less of a visible rolling shutter (the "normal" camera?). It can only be completely avoided by using a camera with a CMOS sensor with global shutter (those are hardly available(?)) or with a CCD sensor (almost not available anymore).

I wouldt try to cover it up with white frames (maybe not 70% opacity).

One that captures images 😀😀

Thankyou for that explanation,yes I also see where strobes dim there are the thin horizontal lines where strobes reduce power by changing frequency (or something) . If I wanted full strobe flashes in every frame, not top half white/bottom half black,top half black/bottom half white, is there a way of doing it without a special camera sync'd via cable to the strobe unit being used? Changing shutter speed, or requesting longer strobe flashes?

As another posted commented these thick roaming black bars are much too jarring on the eyes and brain for my like. I will try the graphic effect manipulations mentioned in the post replies, understanding I likely can't fix thankyou everyone

Requesting longer (/softer??) strobe flashes could be a solution.

But many CMOS cameras are simply annoying in this respect.😒

 

(...by the way: with a thread title containing the word "strobes" and an embedded video with a preview frame of brightly lit faces - isn't it pretty obvious that the video may contain strobing?)

fr0sty wrote on 2/4/2020, 9:16 PM

You could attempt to overexpose (in post) the un-strobed half of the frame to match the strobed part as closely as you can.... it won't remove the effect, but it may reduce its intensity. maybe hit it with a glow effect on the full frame to further smooth it.
