View Full Version : Play videos side by side

As I clean up my uncompressed avi files, I like to compare different results to see the improvements if any. To date I have done a side by side comparison of a still image which isn't ideal but ok. As it gets more to the final product, it's harder to compare with still images. Is there a program that will allow me to play two avi files side by side simultaneously on screen so I can compare them?

Thanks.

Hi!

You could simply open two iterations of good ol' Windows Media Player v.6.4, or any other player that allows opening more than one iteration at the same time...

Thanks. That has some potential. Downloaded the 6.4 version since the old 5.1 version with XP would only play a couple minutes. Still not exactly timed but pretty close. My external fireware 800 drive sure doesn't appreciate running two 24GB uncompressed files at the same time though.

Thanks.

Glad to hear it works for you ;>}

Make sure that one of the instances isn't using the hardware overlay. Otherwise, you may find that one looks darker/lighter than the other.

Another alternative is GraphEdit.

To get them exactly timed, I use an AviSynth script that loads 2 files and places them side-by-side like so:
video1=AVISource("sample1.avi")
video2=AVISource("sample2.avi")
HorizontalStack(video1,video2)
This works nicely, and within VirtualDub, I can compare frame-by-frame too! :) Of course, playing them in sync will be an issue with 24 GB uncompressed, regardless of whether you do it your way or the AviSynth way. ;)

Nice to know that both stackhorizontal and horizontalstack will work.

stackvertical works also.

I sometimes (just for fun) will make trip-out videos like this:

avisource("video.avi")

a=last
b=a.turnright()
c=a.turnleft()
d=a.turnright().turnright()

x=stackvertical(a,b)
y=stackvertical(c,d)
return(stackhorizontal(x,y)


or something to that effect. With some tweaking you can get some very cool results :)

Very nice on the avisynth idea. I l ike the frame by frame comparison you can do. Thank you.

Hello,

is it also possible to put different clips together, only showing one small stripe of each version?

like in this examples: http://msdn.microsoft.com/en-us/library/cc294642(Expression.30).aspx
