Screen Comparison
1. Apps needed
2. Installation
- Download AviSynth.exe file and install it.
- Download ffms2 and put the ffms2.dll, FFMS2.avsi & ffmsindex.exe files in the AVISynth plugins folder, usually: C:\Program Files (x86)\AviSynth\plugins.
- AvsP is portable. Just extract and run!
3. Basic Script
• Open AvsPMod and copy and paste in this script and save it. Open a new avs file and paste this in it:
• Save the above script as source.avs since it will be used for the next script.
4. Hit F5 and AvsP will appear to freeze. This is normal while FFVideoSource is indexing the video. After indexing, you will see duplicate frames in the preview pane. Even numbered frames are from the source and the following odd numbered frames are from the encode. Navigate to the frames you wish to take screenshots of and right click in the preview pane to save your images as PNGs.
• Find a point where the scene change occurs in both sources and make a note of the frame difference.
• Next, you must substitute x in trim(x,framescount) with the frame difference value
• For example: Source 2 (GER) is 2 frames ahead of Source 1 (GBR), you would substitute the value 2 for x in trim(x,framescount).
• Hit F5 again, to apply the changes.
