I don't get it, where is the funny?
As per OP's question, Avisynth can let you stack frames from multiple videos and have them play back simultaneously in player like MPC. Check out the avisynth docs and sub-forum.

EDIT: Cos I apparantly violated the rules (fair cop BTW, not complaining), I'll elaborate. Only your eyes can tell the difference between videos. Metric comparisons can only go so far, and in my experience are wholly unreliable.

The question is whether the OP wants a tool that helps the user to compare videos visually or a program that will do the comparison automatically/mathematically without the help of human eyes
Of course the latter is not possible for most purposes! And I think that is what Sharktooth meant...

@Sem
Hi! I'd suggest to you that "video Quality" is a subjective concept "in the eye of the beholder", because different viewers have different likes and dislikes regarding video - e.g. some prefer a softer image, some a sharper image, some prefer brighter colors, while others prefer "mellower" colors... |

Yes, but there are programs to that can help your eyes. Like inspecting the video frame-by-frame and switching between different versions/encodes easily...

he asked for a "Program to Compare Video Encode Quality"
it does NOT exist. there are program based on commonly used quality metrics, but we all know they are not good for REAL quality comparison. Infact x264 psy-RDO is crap for those programs, while, in reality, it enhances the perceved quality a LOT. Only the eyes are good...

And that question is not clear....
"Program to Compare Video Encode Quality" might also refer to a tool that shows the same frame from different encodes side-by-side or alternating, so you can compare the encodes more easy

he asked for something and not some other thing.
it's CLEAR he wants a PROGRAM that COMPARES QUALITY of different encodes... not a program that helps him to judge quality of different encodes. it doesnt exist. PERIOD.

IMHO that is not so clear. So we will have to wait for his answer...

if he was looking for something different he could have used different word or the search function and would have found avisynth...

Try this in Avisynth:
Code:
clip1 = DirectShowSource("C:\MyEncode1.foo", audio=false) clip2 = DirectShowSource("C:\MyEncode2.foo", audio=false) StackVertical(clip1,clip2)

If it doesn't fit on your screen, stack horizontal and use "extended desktop" on two screens

You could also try this tool here:
http://forum.doom9.org/showthread.php?t=138430 It lets you compare two videos in fullscreen switching between them with the left mouse button. For me it's easier than side by side comparing ala stackhorizontal/-vertical. |
