I tried to add multiple videos to the blending effect, but it was a real hassle to make it work. Because each file took me half an our to get it to work, I made a (Windows batch) script that prepares each video file in the same folder to be used in Powerproducer.

Instructions:

• copy/paste the script in a new text file, give it any name you like but make sure the file extension is .bat


• put all blending videos together in one folder together with the script(file)


• run the script (double click the file)


• the script will make a new subfolder for each video. Move all these subfolders to the BlendEffect folder

Remarks:

• The script will prepare all files found in the same folder including non-video files. It doesn't have any verification or error handling. Be sure you run the script in a folder with blending movies solely annd copy only the associated subfolders


• The type of blending, opacity, etc. are static in the script, but you can always edit the .XML file afterwards if you like.


• It took quite some time to figure it out, but Powerdirector only reads the blending videos when the .XML file is Unicode encoded.


• You can find quite a few well quality (free) blending videos if you search for (free) overlay videos

The script:
@echo off chcp 65001 setlocal EnableDelayedExpansion FOR %%F IN (*) DO ( echo "%%~nF". MD "%%~nF" Copy "%%~nxF" ".\%%~nF\%%~nxF" >nul ( echo ^<?xml version="1.0" encoding="utf-16"?^> echo ^<TEMPLATE_MGR VERSION="1.0"^> echo ^<TEMPLATE_LIST^> echo ^<TEMPLATE TYPE="PRESET" ASPECTRATIO="16:9" CATEGORY="Lens Flare" BLENDMODE="4" OPACITY="200" FILENAME="%%~nxF" ALIAS="%%~nF" TEMPLATEKEY="f604df34-16d6-4d07-92bf-344bd714f20c" /^> echo ^</TEMPLATE_LIST^> echo ^</TEMPLATE_MGR^> ) >"%%~nF"\BlendEffectTemplate.tmp CALL :MakeItUnicode "%%~nF" DEL "%%~nF"\BlendEffectTemplate.tmp ) PAUSE GOTO :EOF :MakeItUnicode Powershell -Command "& { Get-Content \"%~1\BlendEffectTemplate.tmp\" | Set-Content -Encoding Unicode \"%~1\BlendEffectTemplate.xml\"" }" EXIT /B 0
