Feature request: AI-powered video restoration using NVIDIA GPUs

Anonymous — Sat, 24 Oct 2026 14:24:01 -0000

Hello,

Would it be possible to add optional AI-powered video restoration filters to VirtualDub2, using NVIDIA RTX GPUs?

The main features I would like to see are:

AI-based noise reduction for old analog videos, especially VHS, Video8 and Hi8.

Detail restoration without artificial sharpening, halos or invented textures.

GPU acceleration using NVIDIA CUDA or TensorRT.

Native integration into the VirtualDub2 video filter system.

This would be particularly useful for users restoring old home videos who want to preserve the original image as faithfully as possible.

Thank you for your work on VirtualDub2.

FFMPEG reports "unsupported channel layout" and refuses to load the video part

Anonymous — Wed, 05 Aug 2026 19:06:04 -0000

When loading a MPEG2 MXF containing 8 audio channel FFMPEG reports "unsupported channel layout" and refuses to load the video part. Can this be avoided by questioning if the video part should still get loaded anyhow without the audio part?

Full screen preview zoom options request

Hey,

It would be nice to have full screen preview after pressing "Enter" with ability to zoom so the whole
video is in the frame, and not just center, or to have some guards to fit the video fully into frame.

thanks

Can someone create a plugin for VirtualDub2 that allows you to use libass to render subtitles?

#428 How to fade in/out a video?

Anonymous — Wed, 04 Mar 2026 21:25:35 -0000

Sorry for the inconvenience of my former message about the threshold filter as a fade-in/fade-out. I was under the impression it was needed for VirtualDub, but now I see it is wanted for VirtualDub2, and I have no idea if that applies.

#428 How to fade in/out a video?

Anonymous — Wed, 04 Mar 2026 21:19:59 -0000

Easiest way I found, but I have only tried it once: use the internal 'Treshold' filter. In its 'Configure' turn the slider to the darkest position (to the right). Click OK and click 'Blending'. Check 'Apply opacity curve' ( [B] from Blending appears in front of the filter name). When you click OK the Curve tool will appear under the video. Now you can configure which parts of the video will get the black fill or for which part the black fill will be (a percentage) transparent. Do this like this for fade-in and fade-out:

go to the first frame, press Shift and click at the top of the first frame on the Curve window. A red point will appear. This is the frame you start fully black. Now go to the frame where your fade-in will end (and show the full bright video, so where the black filter will be transparent, invisible, e.g. frame 100). Shift+click at the bottom of frame 100 in the Curve window. A second red dot now shows at which frame the filter is fully transparent. A line has connected the two points, showing a gradual fading of the black filter.
Now go to frame at the end where the fade-out must start, say 100 frames before the end. Shift+click again at the bottom of the curve window, and a third red point appears, connecting to the earlier second red dot with a flat line at the bottom of the whole video. Now go to the very last frame, shift+click at the top of the Curve window, and a fourth red dot connects with the third, with a raising line showing that the black filter gets more and more visible again, until fully black.

Curves: you set the points with Shift and click. You can simply drag a dot after placing.
If dots are connected with an unwanted curved line, Shift+click on the closest by the curve will straighten it.
When you want to delete a point, use Ctrl+click.
RTFM for more on curves.....

#475 Virtualdub2 crashes when I try to append more than 3 files together

Also, I tested 4-5 versions prior to this one and the bug exists in all of those, as well.

Using the 64 bit version is a workaround for files too large and crashing due to the memory limitation.. So now my current workaround for only 2 files at a time, is to use AviSynth+ 64bit, and using FFMeg to put all the files together into one file, and then re-edit it a second time in VD64.. I don't like having to do multiple compresses, though.

I am finding this issue too. I can open 1 file, append another file, and it works. But any third file and it crashes. I tried multiple small file sizes.
