How to put two video clips side by side with VirtualDub and AviSynth?

[qingfeng]

I installed VirtualDub 1.10.4 and newest version of AviSynth.

I tried both

clip1=AVISource("C:\path\to\file1.avi")
clip2=AVISource("C:\path\to\file2.avi")
StackHorizontal(clip1, clip2)

and

clip1=DirectShowSource("C:\path\to\file1.avi")
clip2=DirectShowSource("C:\path\to\file2.avi")
StackHorizontal(clip1,clip2)

by "file"-"open video file" in VirtualDub.

However, it couldn't open the video and showed "AVI importer fileter error: (Unknown)(80040154)".

Anyone who can help me fix the issue.

Thank you very much.

What kind of audio and video codecs were used for the AVI. VDub won't open every kind of AVI natively. If you don't know, check with MediaInfo or post a text file from it here.

Or try a different way to open them other than AVISource, FFVideoSource perhaps.

My VirtualDub can open the videos individually. However, when I tried to put two videos side by side using AviSynth, VirtualDub somehow couldn't read the AVS. code.

Re-read manono's response.

What Vdub can read & what AVISynth can read can be two very different things (AVISynth->Vdub is frame-serving uncompressed, so what matters is the input to AVISynth).

I just wonder what kind of code I can apply in VirtualDub to introduce two videos side by side.

Assuming the names and paths are correct, the 'code' is also correct. You're using StackHorizontal correctly. Maybe the problem is the audio. Try this:

clip1=AVISource("C:\path\to\file1.avi",false)
clip2=AVISource("C:\path\to\file2.avi",false)
StackHorizontal(clip1, clip2)

Try opening just one:

AVISource("C:\path\to\file1.avi")

and then the other.

Or provide the information I originally requested.

Here are the information of my video. I did make the names and paths right in my code. Any clue?

I haven't a clue. Sorry. Perhaps someone else can help.

Other than the fact that it's a HUGE bitrate, and it's portrait mode, and it's using odd-numbered dimensions (which might bother many encoders), not sure. Maybe the 2 source filters are also picky about odd-numbered dimensions. Maybe you need to specify RGB24 as the colorspace (pixel_type).

Going for the longest old-thread warning...

I'm trying to compare two videos which have different frame rates, one 25 and the other 50. Both are Progressive (I encoded them with QTGMC FPS divisor 2 and 1 respectively).

SetFilterMTMode ("QTGMC", 2)
    AVISource("I:\Roberts\Capture Masters\Christmas\Christmas.avi")
    ConvertToYV12()
    AssumeBFF()
    QTGMC(preset="Fast", FPSDivisor=1, EdiThreads=8)
    Prefetch(20)

When I put them together with Manono's code, the 50 video (left video) plays at the correct speed, whereas the 25 video (right video) plays at double speed in VDub.

Any thoughts on making them play at the same "speed" ie as if I was playing them in separate windows of VLC Player, hitting "play" at the same time?

clip1=AVISource("Christmas FPS 1.avi")
clip2=AVISource("Christmas FPS 2.avi")
StackHorizontal(clip1, clip2)

Side question: how do I put the filename on each video in the side-by-side arrangement? I've played around with "Info" but couldn't get the second video data to display. I've found this:

StackHorizontal(clip1.subtitle("50"), clip2.subtitle("25FPS"))

But can't work out how get the filename into the subtitle automatically, ie without typing it in.
