- I know of at least three ways that recording can be speeded up:
-
- 1. Get a frame buffer that stores multiple frames that can be recorded
- with only one preroll. Examples: Tektronic's Avanzar (4 frames),
- Abekas A60 (I think a couple seconds or real time play back).
-
- 2. Use edit controller equipment that lets you record say every 30th or
- 60th frame (however long it takes for you to load the next frame).
- If you have the frames stored on disk you can then record every
- 60th frame to the end of the tape then go back 59 more times to
- record the rest. This can be a problem with networked disks because
- of variable read rates.
-
- 3. Use a video disk recorder instead of tape. However, quality is
- subject to debate (we definately debate it here but we still use one).
-
- The above was in no particular order.
