1. Update all your instruments (VrtualDub2 v2.1, AviSynth+, plugins).
2. Create a separate topic for your problem. Examples: one and two.
3. Describe your problem in as much detail as possible, specify the exact version numbers of the instruments.
4. Upload the necessary files (scripts and video files) to a file sharing service so that other people can reproduce your problem on their PC.

Cheers!
I've started a new thread to describe my issue here: https://forum.doom9.org/showthread.p...95#post2011695

In version 667 I have a problem with the folder path in the Deshaker v3.1 plugin. I always have to fill it in, and previously I left it empty (in version 44282) and the plugin found the file in the current project directory.

What file are we talking about?
What is the current project directory?

[rgr]

1. Filter data file (default Deshaker.log).
2. Folder with .vdproject file.

I load the project to 44282 -- I can leave the field empty, the plugin uses the current folder.
I load the same project to 667 -- I have to fill in the field with the full path (I don't know where it looks for it then, but not in the project path)..

What does VirtualDub2 use to play videos? When I enter one into it, the video had 41475 frames, but when enter it into vspreview and Staxrip, it had 33765 frames.

VirtualDub2.

Perhaps your video is Variable FrameRate, and VD2 converts to Constant FrameRate.

Check FR with MediaInfo.

And how does VirtualDub2 convert Variable FrameRate to Constant FrameRate, exactly?

For me, both versions behave the same. I launch any of the versions and immediately drop the project file there. After that, the filter cannot find Deshaker.log.

But if you first open any video file in this folder, and then drop the project file, the filter will find Deshaker.log. And this does not depend on the VD2 version.

Same way everything else does, insert dupes where timestamps have gaps.

You mean duplicate frames? Do all video players (like PotPlayer, MPC-HC, VLC, and MPV) do that, too?

Not exactly. For timecode VFR, frames can display for different durations in a media player. Functionally VFR is similar to inserted duplicates. The difference is no actual frames are being inserted

For CFR equivalent, you are going to have "physically" inserted duplicates. That' s going to be a lot worse compression wise. Think of your apng scenario with 41465 frames is going to consume significantly more disk space than 33765 frames

Would be possible to include nvenc in some way? Some filters unfortunately exists for VirtualDub only and I’d like to create a HEVC lossless mezzanine file for further processing.

[LigH]

Should work via "external encoders", I believe. If nvenc supports piping.

[jay123210599]

I have a 720x480 DVD video. When I extract images out of it, I want the resolution to be 853x480 instead. How do I do that?

[LigH]

Video - Full processing mode; Video - Filters... - [Add ...]: resize

I wonder how you calculated this odd width.

480×16/9 (rounded down)

which may or may not be the exactly correct thing to do, depending on how the original video was mastered.

Personally, I would round up to 854.

[tormento]

Personally, I would keep full res and apply anamorphic ratio to encoder.

[tebasuna51]

Right click over the image and select the aspect ratio desired.

If you have a correct source DVD (VOB file) VirtualDub2 select the correct aspect ratio for you, see the image.
Maybe for your source you need select the aspect ratio manually.
