Video Compare simultaneously software ?

[deadea59]

Hello everyone,

I was wondering if any of you guys had a software that can play 2 videos at once, but the thing was, there was a "common controls" panel for both of them, meaning you can pause in this special panel and both videos stop at once, not just one of them.

I don't want to run 2 instances of VLC, too troublesome to go back and forth.

One example is videocompare.org however the software keeps popping up this arithmetic error overflow box... so I'd like a newer software that can do this.

Thanks!

You can do it with avisynth scripts, and something like mpc or mpchc to play the script

e.g.
a=directshowsource("video1.avi")
b=directshowsource("video2.avi")
stackvertical(a,b)


If you wanted to play side by side, use stackhorizontal() instead , and there are other source filters as well (for other video types)

It's also useful to compare by interleaving frames:

a=directshowsource("video1.avi")
b=directshowsource("video2.avi")
Interleave(a,b)

That way you can flip back and forth between the same frame in each video by, for example, hitting the left and right arrow keys in VirtualDub.

It helps if you identify each video so it's easy to tell which your looking at:

a=directshowsource("video1.avi").Subtitle("video1" )
b=directshowsource("video2.avi").Subtitle("video2" )
Interleave(a,b)

Wow thanks for the quick reply guys, but umm.... I'm not sure what you mean by avisynth "Scripts" ? I downloaded the software linked in the text, but... there doesn't seem to be a software to open? How do I run the script? I also have virtual dub installed.

Thank you guys.

You just open the AVS script in a program like VirtualDub -- as if it was a video file.

1) install avisynth

2) open a text file in notepad in the same directory as your videos. Copy that script, replace the filenames with your actual names, save it. Change extension from .txt to .avs.

3) open that .avs file in media player e.g. MPC

Hello again, thanks for introducing me to Avisynth, thank you especially poisondeathray for the simple instructions, I got it working.

However, this wasn't what I expected... I was hoping for something where I'd have a little control over when to pause and when not to pause on a specific video. There are random 1-2 second gaps between the two and I don't want to keep pausing, and edit the file for just that short gap just yet! I want to pause for the other video to catch up.....

Thank you all.

Open your two videos in an editor like VirtualDub (two instances). You'll still have two programs to control but you can single step through them easily.
