VirtualDub2

[nji]

... and how is the logic in orig 44282 release?

Just want to thank the author for continuously updating this important tool.

Current builds support even JPEGXL, WEBP and AVIF image sequences as input, which is unheard of in "professional-grade" software (Adobe Premiere, DaVinci Resolve, etc.). Extremely important for my workflow. Thank you!

@v0lt

I had no idea that a new version was out already. Can you tell me the major improvements of the new Virtualdub2? I am currently on Windows 10 on a mini PC/

Most important improvement: Supports ffmpeg Version 7.x and new codecs available since then (e.g. AV1, VVC decoders).

Can VirtualDub2 handle and show HDR colors? If so, how?

No. VirtualDub only supports Bt.601 and Bt.709.

What about your newer version of it?

I'm trying to make a direct stream copy as opposed to a stream copy. My goal is to trim the video before a certain time. I can do this using Stream Copy, but Direct Stream Copy requires a different input driver. I'm trying to avoid an error where the audio and video do not match each other. What is the best way to accomplish this? Do I disable the caching input driver when it comes to Direct Stream copy? Or do I use something else?

Yes, in this case you get the usual VirtualDub work, but it will work for AVI and you will need the VFW and ACM codecs.

The Caching input driver seems to be able to copy I-frame only video streams. I haven't checked.

What is the best way to accomplish this?

Try Avidemux.

I ended up using AVIDemux as even the exported "Stream Copy" version was off by a few seconds. Virtualdub2 (or the 44282 version that I was using) will not Direct Stream Copy the video I was using. For context, I used a file that I dumped with FFMPEG although I think I should have used a simpler script. It looks like it works now

I want to convert a video to APNG, but I also want to resize the output APNG. How do I do that?

Make frame resizing (and cropping) for Export > Animated PNG the same way as for regular video. More details are written in the help and on the Internet.

Thanks, it also takes a long time for VirtualDub2 to convert the video to APNG. How do I speed up the process?

Buy a computer with more processing power!

Hello! I've been visiting Doom9 as a Guest for a year or two now, often finding answers to video questions that other sites aren't discussing, and I've learnt such a lot from so many of you - I'm really grateful, a huge thanks to all of you!

I've now registered to ask specifically about newer versions of VirtualDub2 failing to open some of my Avisynth scripts with the message "System exception - Access Violation" when older versions of VirtualDub2 handled them fine.

Is there a go-to page with general advice about how newbies can get started with reporting apparent bugs? Is this particular thread an appropriate place to report details about my VirtualDub2 problem? Cheers!

[Emulgator]

I guess this here is the thread to report.
If you want to narrow down any faults I suggest to make a testbed as follows:
Do not install anything, just unpack.
Place all concerning VirtualDub versions side by side, each in their folder.
Start with "vanilla" versions, only default plugins.
Place all concerning AviSynth versions side by side, each in their folder.
Start with "vanilla" versions, only default plugins.
Now do take care of their plugins folders.
Copy your "previous" versions, with your previously trusted plugins into a "plugins_previous" folder for each AviSynth and VirtualDub pack.
For each AviSynth and VirtualDub pack make a "plugins_inactive" folder for swapping.

Now you activate/deactivate your AviSynth versions using Groucho2004's batchfile.
You don't have to install anything, just download the versions you are interested in and unpack them.
In the end you only run a .bat script which does the "install" (writing regkeys and copying a few .dlls).
https://forum.doom9.org/showthread.php?t=172124
(You may go to the last page, I have updated some paths/versions there)

Then load, preview (F5), reload (F5), play, test encode your scripts using AvsPmod
https://forum.doom9.org/showthread.php?t=175823

Then test/preview using VirtualDub (load, reload (F2), Play (F5), test encode (F7) for all kinds of files/scripts.
Then swap only the plugins in you need, one by one, F2.
Report the one where it fails, exclude other faults. And so on.

BTW, regarding VD: Depending on your workflow you won't need the latest and greatest.
I feed scripts anyway, and these rely on AviSynth source filters.
Since VD is used just as .avi writer here, it gets piped video data, and pipes it to a simple intermediate encoder.
So no need for the latest VD input decoder, my use case works well with earlier VD versions down to 1.10.5 and 32-bit
Any elevated encoder form MPEG-2 on would get the script fed directly.
