Program to compare encodes windows, individual, something, forever

andy

How can I compare individual frames of my DVD encodes?  I know I can open each DVD, scan to a frame, and save it, but that takes forever.  What I'd prefer is something with 2 separate windows (like virtualdubmod)

Anyone know of something like this?

is there anything even remotely like this?

avisynth
stackvertical(a,b)

I created an avs file withCode:
clip1 = DirectShowSource(quot;I:\OUTPUT\HC Encoder\VIDEO_TS\VTS_01_1.VOBquot;)
clip2 = DirectShowSource(quot;I:\OUTPUT\QMatOp 6 Pass\VIDEO_TS\VTS_01_1.VOBquot;)
StackVertical(clip1, clip2)
but when I open the file in virtualdub, the two encodes are out of sync so their frames don't match up

also, is there any way to make these videos fullscreen so I can notice differences easier?

Use Media Player Classic and then press Alt+Enter.
