One Touch Recording or OTR. A function on my old VCR that enables me to record a TV program immediately without delay. And with the ability to set a countdown timer, the VCR will shut off once the countdown reaches zero.
I wanted something similar to OTR on my PC for my TV recordings with VirtualDub. There are times when I wanted to start recording a TV program immediately without scheduling a task in V2CRS. Task scheduling is easy with V2CRS but it takes time keying in the parameters. Consequently, there is an undesirable delay when I want to start recording immediately.
Batch Files To The Rescue
The easiest method that I could think of in creating an OTR like function on my PC is to use Windows batch files, that will in turn call the V2CRS program "Scheduler.exe". VirtualDub capturing will start almost immediately plus I will get a countdown timer, courtesy of V2CRS.
A command for immediately capturing TV1 (channel 6 in my case) into the file name "TV1" in the directory "F:\RecordedTVPrograms" for a length of 30 minutes will look like this:
