new drivers still do not fix these two major bugs
1.) Downconverting 720p HD to SD on output is broken. 720p native playback is fine, but when the “output processing” is set to SD downconversion in the Decklink Systems Preferences playback is glitched out (crazy stuttery w/ rapid scaling) and usually results in a complete freeze of FCP.
2.) Photo-Jpeg playback is buggy. The gamma changes from when the playhead is parked to when you’re actually playing down. Hit play and your image “pops” to a different gamma, hit stop and the the image “pops” back. Applying effects or transitions across photo-jpeg material will result in a gamma pop between rendered and non-rendered material.
I’ve heard that #2 is a FCP bug…. STILL, BM continues to list photo-jpeg as their offline codec of choice so it should work, and it doesn’t.
Anyword from BM on fixing these two major bugs?

I’ve seen that gamma shift for years and asked our engineer, she said it was probably the way the compressed image renders on a still frame (averages up in chroma). dont hold your breath waiting for BM to fix the bug, ive been waiting for years for BM to fix the A to D (yrb) side if thier multibridge. In NTSC they have the SMPTE and Betacam levels flipped so you CAN NOT dail a proper component signal out of it, Ironically PAL is Fine.

Haven’t seen the multibridge bug, but we never convert A2D via Decklink (we’ve got a hardware solution in our rack for that). Totally wouldn’t be surprised if there was a bug there.
STILL, the gamma shift is DEFINITELY a NEW issue. Everything w/ Photo-Jpeg worked fine in FCP 5 – 5.14. We use photo-jpeg as an archiving codec and have over 1 TB of data encoded in it. It’d be horrible for us if we had to recompress all of those movies just because FCP can no longer properly play it down….
Any word BM? I’d love a response on this, even if it’s merely “blame fcp 6” kind of a response.

I’m getting that crazy resize/flicker then freeze and crash of FCP 6.02. Don’t know if it’s this supposed “bug” in FCP or QT7.3 or a separate problem.

Tech support says 720P 24 downconversion has never been supported. I had it working a few versions ago. Now it just seems broken. So it was working. Anyone have any luck getting this to work right?
