STILL NEEDING Help! Decklink HD Pro drops signal
Luke / Matt any hope of solving this soon???
>>>>
BOTH our Premiere Decklink HD systems hiccup cutting from 8bit SD YUV to DV on an 8 bit SD timeline. The SDI out signal disappears for a couple of frames, audio and video. Even scrubbing frame by frame this happens at the cut point going to DV from 8bit. It is like the card is having to relock at the cut point.
Both our Decklink SD plus systems are fine with the identical clips and timeline.
What is going on? This happens with drivers ver 5.1.1, 5.1.2, 5.2, 5.2.1, 5.2.2, quicktime 6.52 and 7.02. This happens whether there is external sync or not.
My only workaroud is using 5.2.2b (beta) which oddly requires a render of all DV material.
Thanks for any suggestions
Can someone else with an HD Pro try this for me and confirm?
My systems are Tyan s2895 with FX6800GT video cards, 2 gigs ram, 1x300gig system drive, 1-300gig audio drive, and 3×300 gig. windows stripe set.

Hi Shane,
Matt is at InterBee Japan at the moment. This is an odd problem and I’m not aware of any other reports of it so we’ll test it here and let you know. Are you using the DeckLink HD Pro 4:2:2 or 4:4:4 card in this test?

Check the previous thread. Matt and I were back and forth on this a number of times and he said he had tracked it down.

Thanks Shane,
I don’t think Matt got a message to me before leaving for Japan so I’ll try to find out some information from the engineers and let you know.

Hi Shane,
I spoke with the engineers here and they directed me to a paragraph in the support note Premiere Pro 1.5.1 caveats with DeckLink v5.1.2 which is still applicable with the latest drivers.
—
Avoid mixed-format clips with NTSC sequences and DeckLink HD Pro 4:2:2 & 4:4:4 cards.
Due to an issue in NTSC sequences with mixed-format clips and the DeckLink HD Pro 4:2:2 & 4:4:4 cards, we recommend using either 8 bit clips or 10 bit clips exclusively in any one sequence.
—Subsequent to this support note, the problem has been partially resolved in the 4:4:4 card. You can add DV to an 8-bit timeline but any effects will still require rendering.
A full solution is in the works. I hope this explains the current problem and we should have a full solution shortly.

I’m not mixing 8 bit and 10 bit. I’m only mixing DV and 8 bit. The only caveat on DV is…
“Mixing DV and uncompressed video
When mixing DV and uncompressed video on the same timeline be sure to use the Reverse Field Dominance option on the appropriate clips so that the effect, filter or transition is rendered correctly.”What I’m seeing is the SDI out disappear at an edit point.

Hi Shane,
I’m sorry for the long delay as our test suite was extremely busy, towards the end of last year, with Multibridge Extreme. It’s still busy with the other new PCIe cards but it’s not as busy as it was.
We have tested your problem with Decklink 5.1.2, 5.2.2 & 5.3.1 drivers without encountering a problem. We were able to capture & playback both BMD DV clips & standard Microsoft DV clips & Uncompressed 8-Bit without a glitch or any need to render.
Are you still encountering this problem? I’m not aware of any similar reports.

Thanks for the response. The problem doesn’t show up in day to day editing but more in long renders in Premiere
Try this….
In Premiere open an existing BM 8bit NTSC 4×3 project with a 1/2 hour timeline of clips and try – Project/Project Manager/create trimmed project. With 8 bit NTSC sources my error is “There was a problem copying or trimming the following file….” With DV sources it will crash after 5 or 10 minutes of rendering with the famous “Sorry, a serious error has occurred that requires Adobe Premiere to shut down….”
Do you get the error? If not I’ll keep rebuilding our systems and assume it is me.
On my systems I’ve tracked this down to the “BMDimporter.prm” plug in. If I remove it the render will run, but I wouldn’t want to try editing without the plug in or something might be corrupted.
Thanks

Just to clarify…
The original “drops signal” problem you fixed with 5.3…cutting from DV to 8bit (or was it the other way around) caused a hiccough on the output of a HD Pro 422.
May current complaint is one of stability in long renders that showed up with 5.2. It makes it impossible (on my systems) to do a “trimmed project” in Premiere with any driver since 5.1.2 . Can you check this for me?
