Compare 2 videos (quality)

[Gordo_]

I have to different videos with same content, and I'm only keeping one of them. Is there a program that makes it easy to compare the quality of the 2 videos?

What, specifically, are you looking for ?
Quantify quality ?

You can have a look at the these tools to see if they fit

But the best judge is your own eyes.

Try this:
https://www.videohelp.com/tools?tool=AVIcodec
Besides all its other functions, it shows the video quality of the video file analyzed

avicodec (and g-spot and a few others) shows the quality setting used by the encoder. Realistically this is meaningless in terms of the quality of the image, as all it refers to is the quality setting of the encoding itself. A poor image, really well encoded, is still a poor image.

You can run two instances of VirtualDubMod side by side to compare two videos.

You can use AVISynth and one instance of VirtualDubMod to compare two files with a AVS script like:

v1 = AviSource("video1.avi")
v2 = AviSource("video2.avi")
StackHorizontal(v1, v2)

An AVS comparison which also shows the differences between the two videos:

v1 = AviSource("video1.avi")
v2 = AviSource("video2.avi")
sub = v1.subtract(v2)
substrong = sub.levels(112,1,144,0,255)
return StackVertical(StackHorizontal(v1.subtitle("origina l"),v2.subtitle("encoded")),StackHorizontal(sub.su btitle("Difference"),substrong.subtitle("Differenc e amplified")))
