VDTimer is a timer/scheduler for VirtualDub capture. After you have added items to the schedule, make sure VirtualDub is running in capture mode, and check "Enable Timer". VDTimer will start the capture by pressing F6, and stop it by pressing Esc. It also automatically renames the capture file (it checks before starting and after finishing). The schedule is saved to disk when exiting, and reloaded upon next run.
NOTE: VDTimer wasn't designed to work with VirtualDub's "multisegment capture" or "autoincrement filename after capture" options.
