I would wholeheartedly endorse what @browj2 has written.

I use the Neat Video plugin, also handy for removal of flicker in videos.

https://www.neatvideo.com

There is a demo version on their site if you want to have a play with it.

Hi

+1 for the Neat Video plugin - however there are 2 not so small details to bear in mind:

1. when rendering/exporting the output frame rate can drop to as low as 2 - 3 fps
    
2. if you want to work with 4K video you need the Pro version.

Thanks for the tip on Neat video you all.

I used it in the past with virtualdub if I remember correctly and it did an ok job with noisy video.

Was hoping VPX had something on the go without having to buy additional plugins.

@marcusdeman
As mentioned, Neat video is very processor hungry.
A 45 minute multi cam video can take 12 hours or more to mix down if the whole lot needs noise reduction.
You also need to sharpen a lot after applying the effect.
I still can't work out why anyone would want to "Render"
Just export the video to the format of your choice (WMV or MP4) then preview from there.
You can then use that video to produce DVD if you wish. Rendering takes a long time to then have to export anyway.
Just my opinion, works for me.

Neat Video benefits more from the GPU than the CPU. If I render CPU only I get about 3fps, the GPU (RX480 8G) gets 17fps. Neat also has built in sharpening tools so you shouldn't have to do any sharpening after applying the effect. If I have any clips that look like they need some help in Neat Video I will first try a section of the clip, if it can be rescued the clip stays in the edit and I apply Neat Video to it before the final export to minimise the performance hit. I use Neat quite a lot when using high frame rate footage, more often than not it's the flickering of lights that's the issue more than noise.

I would also suggest uploading a private clip to Youtube (assuming that's the where you publish), the compression algorithm they use sometimes kills a lot of the video noise.

Hi Doug,

I think that a slight precision is needed here. Pre-rendering (Ctrl+R) is what is done in the program with the lightning button in the button menu. By rendering, I think that we usually mean rendering out or exporting to a format that can be used in the program to replace the un-rendered version.

For example, with 8mm/S8 digitized material and VHS, I do a rough cut, apply Neat Video and possibly Mercalli V4 Stabilization. I render (export) that out to an intermediate, always mxv, when convenient, like when I have to do something else away from the computer or at night. Then I bring in the mxv file, cut it up into scenes where required, replacing the original material (saved with a different filename/revision). Then I use that for further editing. Everything is much smoother and I don't have to redo Mercalli if I trim a clip. The final export is then also much faster.

I had a disastrous experience in creating a DVD of a 1 hour+ video that contained a lot of Neat Video. After about 48 hours, the result was a terrible, unusable. I then exported to mxv in parts to mxv, and used those instead of the original heavily-edited material. No problem with creating the DVD and done in a reasonable amount of time.

Hi John.
Yes I guess it differs for everyone.
All my editing is multi cam sometimes using 15 cameras. If they all need some amount of neat video then sometimes it can take up to 30 hours to export.
I have never had a bad result from the export so I keep using that method without rendering.
MXV is no help to me because I then need to export that anyway.
I don't use Magix DVD function anymore because they still haven't fixed the problem with the choppy fades at the transitions so I have moved to DVD architect."Much more professional result and more options.
Magix own that now so I hope they don't break that one as well.
Thanks for the reply.
Doug.

Hi Doug

. . . . All my editing is multi cam sometimes using 15 cameras. If they all need some amount of neat video then sometimes it can take up to 30 hours to export. . . .

Is this just for the clips that end up in the final movie on track 1/2?

. . . . I have moved to DVD architect."Much more professional result and more options. . . . .

I could not agree more - so much more versatility and range of possibilities.
