I use a bit of powershell for work, so when it came to configuring postprocessing stuff for a freshly installed OS and new configuration of NPVR, I opted to rewrite in Powershell.
Not so much looking for support (I have everything in my configuration working (knock on wood) that I can tell) - but I figured I'd post up what I wrote just in case anyone else is interested. As usual, use at your own risk. Oh, and I wrote and tested all of this on Powershell 4 in Windows 7.
Here's what my main postprocessing.bat file looks like:
StreamFix.ps1: This one runs the .ts files generated by my HDHR through VideoRedo to fix junky timelines and kicks out a .mpg file.
and Comskip.ps1:
