I have VAP set to run commercial detection and output a vprj file which I then open in VRD to verify the cut points and then output the final mpg. VAP almost never gets the commercial points correct so I always end up having to verify them.No direct way. You could do it in a VAPpostProcess.cmd script file but that will only be run if you let VAP complete processing, i.e, not just do commercial detection but also output the file with commercial cuts applied. I'm not sure what you meant by "when only doing commercial detection."
If you manage to rename a file in the Monitored folder, VAP will then see it as a new file and queue it for processing. Depending on how you rename it you could possibly use input file-ignore or filtering settings to prevent that.
Another trick would be to use two instances of VAP. VAP1 would be configured with no QSF or AdScan/Comskip ops at all, which will cause it to simply move files from the Monitored folder to the output folder, meta-renaming them in the process. Then VAP2 would have the VAP1 output folder as its Monitored folder and would do the commercial detection. You can run VAP1 and VAP2 concurrently or one-at-a-time. Search for the -config command line option in VAP-readMe.pdf for details on this.
No I had been double clicking the file in explorer to launch VRD because Im sometimes doing it the next day and VAP is running in the tray. I will try your method tonight.I assume you're opening the .vprj file in VRD (to verify/adjust cuts) by clicking the "Run VideoReDo" button in VAP (When the commercial scan is done and the file goes into AWAITING CUTS status) -- correct? If you do that, VAP then runs VRD to create the final meta-renamed output file, and a VAPpostProcess.com file will be run (if it exists). You can rename the input file in that script.
Search the VAP-ReadMe.pdf doc on "vappostprocess" to get more details, including the four arguments that are passed to the postprocess script. If you need more help just post.
BTW the cut points are determined either by VRD or ComSkip, not by VAP. VAP just runs one of those programs.
