How to gain a working knowledge of video

5 points by KochamCiebie ↗ HN
I really enjoy using analog video gear. As an audio person, video feels like a whole new world! However I find I’m running into walls that reveal my gaps in knowledge, and I’m seeking a deeper understanding. I wanted to ask here for advice and resources to gain a more practical working knowledge of how video works, so I can do more with what I have. I wouldn’t say I’m a beginner but i am needing some basic knowledge.

For instance here are some questions I feel I’m swimming around in the dark with; - how to transfer video to/from different resolutions without it getting messed up— A laptop to a vhs, a vhs to a laptop (I have been using vidbox but wish it could look better). - how do time base correctors work and why do we need them? - why do I need a powered piece of hardware to convert hdmi to rca?

TBC's act as a heartbeat for video frames to prevent an analog glitch in the otherwise 30-frames a second of interleaved video. Those innocuous glitches can screw up edits, digitizing, and produce so many errors down stream when you make copies, etc. They'll sync different cameras to the same frame refresh so that live edits won't flip when you change camera views mid-frame. They are expensive and worth it if you mess with analog video.

It sounds an awful lot like timecode. I'm used to syncing my audio mixer's timecode to cameras. Are TBCs similar to timecode?
