The tutorial videos for FirstLight (linked in my previous post) made it look very simple. And indeed it pretty-much is, but Sony Vegas introduces a “bijou problemette” (franglais) in teh form of its Video Preview cache, which lacks a corresponding “Clear Cache” button. As a result, when I first tried using FirstLight with Vegas (10e), adjustments in FirstLight did not always show up in Vegas. The possible solutions are:
- In Vegas, set “Dynamic RAM preview (max) MB” to zero. Then on each FirstLight change, just wiggle Vegas’s timeline cursor (playhead) at least couple of frames either way (moving it by just one frame is not sufficient).
- Alternatively, if “Dynamic RAM preview (max) MB” is not set to zero, then on the Preview window, try flipping between settings, like from Good/Half (my usual setting) to Good/Full. It’s no good doing an open/close of that window or indeed changing its scale – these seem to have no effect on the cache.
