Compare Video Side-By-Side ?

[BassKozz]

Are there any applications that let me view video files side-by-side to get an idea of the quality differences?

I am in the process of transfering VHS to DVD's and I am trying to compare different encoding and captureing methods... but I can't seem to find a way to view two seprate video files side-by-side... any suggestions?

two copies of media player classic two copies of virtualdub , one (or two) copies of almost any NLE in which you can all (of them) display two video streams side by side

AviSynth is perfectly suited for this. Problem is, you'll have to learn a little about AviSynth.

#simple AVISynth script to view two AVI files side-by-side
StackHorizontal(AviSource("_before.avi"), AviSource("_after.avi"))

2 copies of a software player isn't that good, unless you disable the overlay first. Otherwise one will use it and the 2nd won't. You can play 2 examples of the same video, and with the overlay enabled they'll look different from each other. Either disable it, or open 3 instances of the same player and use the 2nd and 3rd for comparison purposes.

AviSynth's StackHorizontal (or StackVertical for widescreen videos) is ideal for this.

MPEG Video Wizard uses two windows, with similar looks and controls, for previewing clips and edited content. They call them Monitors. The Monitor for previewing source clips is called the Input Monitor, and the Monitor for previewing edited content on the Timeline is called the Output Monitor.

You can preview the different or same files in the Input Monitor and Output Monitor side by side.

Wish to help you.

There are a couple of avisynth scripts to do this in this post -> https://forum.videohelp.com/viewtopic.php?t=297929

The first script actually does a split screen so you can compare the original in one half of the frame, and the new version in the other. I use this script for most of my cleanups.

the problem with avisynth scripts is that you can not step through or go back to review an area ..... not a very good solution

[guns1inger]

You can if you load it into vdub or MPC

The problem with avisynth is it only plays AVI's correct?
The files I'd like to compare are in MPEG format.


Nightcat,
I tried out Wooble MPEG Video Wizard, but I can't figure out how to play a file in the output window/monitor... everytime I open a video it only opens in the input window/monitor.

I haven't had a chance to try any other apps as of yet.
Please help,
Thanks,

No, there are plugins that allow MPEG or almost any other kind of video as a source.

To play MPEG videos side by side, first make D2Vs for both using DGIndex. Then you'll also need the DGDecode.dll that comes in the same DGMPGDec package that includes DGIndex:

LoadPlugin("C:\Path\To\DGDecode.dll")
A=MPEG2Source("C:\Path\To\Video1.d2v")
B=MPEG2Source("C:\Path\To\Video2.d2v")
StackHorizontal(A,B)

Or use a variation of the script to which guns1inger posted a link earlier.

I cut each video in half (right down the middle) using CROP, then use STACKHORIZONTAL to view both versions on the same page as one video. Allows you to make pretty quick decisions on your changes. All this is using AVISYNTH, of course.

Using VirtualDub, you can step forward, backward and access the video randomly.

Hi. I'm sorry not to explain this before. The Output Monitor is for previewing edited content on the Timeline.

The step how to open file in Output Monitor is below:
1) Open the files in the Project Manager.


2) Select the files in Project Manager, drag and drop them into the Timeline.


3) Click the 'Play' button in Output Monitor to preview the video file which edited on Timeline.
