You can’t "upload" it. You have to play it. In real-time.
If you’re working on remastering or simply archiving a show from the mid-2000s to early 2010s—let's call it Season 03 of a cult drama—you’ve probably heard the phrase: "We just need to upload the HDCAM tapes." upload s03 hdcam
If your post-production mix for Episode 03 had 8 discrete tracks (Dial L, Dial R, M&E, SFX, Stems...), you need to route those via the deck’s audio output card to your capture card. Miss a track? You lose the isolated score. Good luck remaking that. Because these tapes are 10-20 years old, the LTC (Longitudinal Timecode) track might be degraded. The deck might struggle to lock. If the timecode drops, your capture software might stop recording. You can’t "upload" it
