site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com Hi Paul, Dynamic down-ressing is a feature of FCP's RT engine. There are certain features that aren't available in the RT engine, and if your plugin uses one of those features, we'll run it in another, "non-RT" codepath that doesn't do dynamic quality adjustment. If you use the FxTemporalAPI (and set the mayRemapTime flag in your poperties dict), you'll find yourself in this state. You'll also find yourself here if you have any non-empty image well parameters. - Paul On May 23, 2011, at 7:08 AM, Paul Miller wrote:

I have a CPU-based FxPlug that a customer tells me is dot down-rezzing in dynamic mode. He says his other effects are doing it when he scrubs. Unfortunately I only have a recent MacBookPro and I can't get ANY effect to down-rez, even HD clips with multiple stacked effects. This is making this quite difficult to track down.

First, is there a trick to getting a MBP machine to go into full dynamic mode when scrubbing? I've turned on all the dynamic options I can find, but it's always previewing at full size.

Second, is there a trick I need to make in the code to get it to downsample? I'm already periodically calling FxProgress userCancelled, but not very often - a couple of times during each frame's render.
