VirtualDub fork and plugins

[MogomraZero]

Good afternoon! I am trying to open AV1 files in VirtualDub 2, but whenever I try to do so, I get this error message:

FFMPEG: Unsupported codec ([0][0][0][0]).

What do I need to do to resolve this error message so I can open my files in VD2?

Thanks you very much in advance for your assistance!

If I were you, I would open the AV1 files through Avisynth's ffms2 plugin.

1) How would I go about doing this?
2) Would it be frame-accurate?
3) Would I be able to see the file's keyframes by doing so?

Vdub2 doesn't support av1 videos

Format : AV1
Format/Info : AOMedia Video 1

Perhaps install Avisynth then you can use a simple script to get the file into Vdub

[jagabo]

1) How would I go about doing this?
2) Would it be frame-accurate?
3) Would I be able to see the file's keyframes by doing so?

1) Install AviSynth. Install the LSMASH Source filter for AviSynth. Create a script with a text editor: LWlibavVideoSource("filename.ext"). Open the AVS script in VirtualDub.

2) Yes.

3) No. And no lossless or "smart" editing. You will have to reencode.

Unfortunately, using either FFMS2 or LWlibavVideoSource to try and open the file in VD2 results in the error message "failed to get the video track". The scripts work fine with the raw uncompressed video source file. Does anyone here know what may be causing the new error message?

[davexnet]

Run the video through MKVTOOLNIX Gui to create an mkv,
Try that with the source filter(s)

Sadly, that did not work - still getting the same error message.

possibly old version of ffms2 or lsmash . 10bit 4:2:0 AV1 should open no problems with modern version

You can identify I-frames with propshow for lsmash and ffms2 (if it's reported for the codec) , or ffinfo for ffms2 . (Not all I frames are necessarily keyframes, some are "open" GOP and not true keyframes) . If using avisynth, it gets decompressed, so there is no notion of "keyframes" since everything is uncompressed. The frame type refers to the original file.

Thank you very much - I updated both of those plugins and I am now able to see my AV1 footage in VirtualDub using both methods!

Is there some documentation or tutorial video available regarding using propshow to find i-frames in a video? I just want to make sure that libaom is putting keyframes in at the intervals that I am requesting.

You need to use a recent avs+ version . Just add PropShow after the source filter

LWLibavVideoSource("video.webm")
PropShow

There will be an overlay in the top left corner with info about the video, if it's reported by the codec and read by the source filter

_PictType is the picture type, and it will report I,P or B frames

That is EXACTLY what I needed, and it looks like I-frames are being placed where I requested by the codec! Thank you VERY much for your assistance with this!!!

Thanks for that!

[poisondeathray]

Anyone know how shekh / Anton is doing ? He hasn't been active here or Sourceforge in quite a while. Hope he's ok

It would be nice to have an update to the vdub2 cacheing input driver to include AV1 (and soon VVC)

Thanks for this hint. Very useful.

He responded in January to a request, so he seems to be ok but has no plans re. Vdub2, it seems.

Hi - new here and may have missed something simple... is it possible to show the time (hh:mms) on the timeline instead of the frame numbers?
Thanks

[Alwyn]

Options>Preferences, Timeline.

[W1itchseason]

I was looking at Options > Preferences > Timeline - it allows me to change the time format shown in the 'info text' under the timeline, but (as far as I can see) doesn't let me change the units used on the 'trackbar'.

[Alwyn]

Arrr yes, I see what you mean. When find out, let us know!

[DarrellS]

It looks like this thread is dead but I'll give it a try.

How do you get Virtualdub2 to open sequential files under append video segment? Linked Segments is grayed out as is Open Using Input Driver (caching Input Driver). The only options are single file or Sequential: 1 file.

I like that Virtualdub2 will open files that Virtualdub refuses to open because the framerate is a millionth of a second different but Virtualdub will open sequential files that match while Virtualdub2 will only open one file at a time. That gets very tedious when you have 20 or more files to open. You end up opening the same file twice or miss a file

Right now, my only other option is to re-encode every single file and make sure the framerate is 29.9700000 and use Virtualdub.

EDIT: Then Virtualdub2 won't direct stream copy those 20 files. Never mind. This program is useless.

On some file types,
file/export/stream copy
can be used

Avoid merging files in VDub -- if the audio track is shorter than the video, you will have an audio offset from the second file.

I remember you could get around this by adding an empty file and then truncating it. VDub2 removed part of the video track, but only part of the audio track, and the length of both tracks then matched.

[DarrellS]

I tried again and on the second option, it showed 15 sequential files instead of just one but when I clicked open it only opened one file.

I also tried the option File/Export/Stream Copy and it only copied the first file that I opened. Not the rest of the files I appended. Why is there a "Direct Stream Copy" option under Video if it doesn't work?

I haven't had any sync issues with any of the files that I've joined.

Another issue I do have is the cropping feature in Virtualdub2. It's ridiculous. Nothing like the crop feature in Virtualdub.

EDIT: OK, I guess there is no fixing the append feature. You have to add one avi file at a time. I got the same error about the framerate being off by .0003 but I was able to skip that file instead of going through all the files to find out which one was off .0003. I changed the input driver from Caching Input Driver to Audio Video Interleave Input Driver and the Direct Stream Copy feature under Video now works.

Just ignore me if I've misunderstood - I'm not very techie - but these are my settings:

What type of "issue" do you have with VD2's Crop feature? I use it frequently and can't visualise a problem, but then I've never used VirtualDub and hesitate to try it because the latest version is so very old.
