I’m running 4.0.2 on Win XP Pro. Even tried with the new 5.4 DL drivers and QTime 7. Same problem. I’m trying to get a post through to Autodesk about the issue; it might be more on their side, since the problem only shows up in Combustion.

No, sorry I wasn’t clear: The bars that BM provides on their site (as an AVI/QTime file) are 100% saturated, as opposed to NTSC/SMPTE 75% saturated bars.

And please note also: the bars supplied by Decklink are not SMPTE bars.

FYI: Premiere Pro 2.0 is supposed to support 10-bit fully.
We’ll see.

Another one is called MacOpener. Works well for me, exchanging HFS formatted FW drives with Mac systems.

Mac- I understood. Thanks for mentioning the issue. Maybe someone from BM will confirm this behavior on one of their PAL setups.
I have not noticed this on NTSC, but it may be there. My layback is typically with a black or still frame at the start, so I might not have noticed it on my system. I’ll try and confirm for NTSC.

Try installing the same driver on top of the existing one; you’ll probably get a choice to “repair”. Do that, and you may be able to uninstall next. I think something like that worked for me a few months back.
best of luck,

” Do not use 4:4:4 RGB codec as the camera outputs only 4:2:2 so it would be just uneeded waste of bandwith and money you would need something to convert YUV to RGB”
Yes! what was I thinking? I forgot 4:4:4 was an RGB, not YUV codec.
sorry

Hi Matthew,
I can’t say with any degree of confidence what the difference would be, but it seems that Varicams typically record to DVCProHD ? So the Wikipedia entry that follows might put it in perspective. Direct capture to 4:4:4 would be best if you have the bandwith & storage to manage it.from Wikipedia:
DVCPRO HD, also known as DVCPRO100, uses four parallel codecs and a coded video bitrate of 100 Mbit/s. Despite HD in its name, DVCPROHD downsamples native 720p/1080i signals to a lower resolution. 720p is downsampled from 1280×720 to 960×720, and 1080i is downsampled from 1920×1080 to 1280×1080 for 59.94i and 1440×1080 for 50i. Compression ratio is approximately 7:1. To maintain compatibility with HDSDI, DVCPRO100 equipment internally downsamples video during recording, and subsequently upsamples video during playback. A camcorder using as special variable-framerate (from 4 to 60 frame/s) variant of DVCPRO HD called VariCam is also available. All these variants are backward compatible but not forward compatible.
DVCPRO cassettes are always labeled with a pair of run times, the smaller of the two being the capacity for DVCPRO50. A “M” tape can hold up to 66/33 minutes of video. The color of the lid indicates the format: DVCPRO tapes have a yellow lid, longer “L” tapes made specially for DVCPRO50 have a blue lid and DVCPRO HD tapes have a red lid.
Happy shooting,

If you have a DeckLink card, why not just rent a deck for a day? Probably cheaper than paying hourly rates for that big a file transfer/layback.
