In a Vegas project, I have one large video that's been split (I pressed the 's' key) several times, aligned manually, and trimmed. I would like to extract either the frame number of the time offset of each of these clips relative to the start of the original video the clip came from. (I'll use this information in a Python script to perform video analysis.) Have can I obtain these values? Using the UI to get the time offset is fine if that's possible; no need to script the time offset extraction.
