Hi,

jepp, also same problem…for the moment is decklink
not really usably..

i have some more problems:
-when rendering the green bar over the clip dissapears..
i have to zoom in or out in the timeline to see if
the clip is rendered!
-Next problem: when i dublicate a timeline to make changes
i have to render all the clips again in the new timeline.
(in the old timeline they stay rendered!!!)
-when i edit dv and apply a effect, i have after i rendered the
clip a “line jump”!!! (Very old problem, posted many times!!!)
– When i open a project, many times premiere has to (i don´t
know how it is in englich!) “apply” the audio for all clips
again (right bottom corner in premiere)
– Also when i reopen a project Premiere has to render some effects again!!!
– The serial device Control doesn´t work!!! Some “com” Problem
I have to use Decklink Device control, and this one is long not so good as serial device Control!!!!
– When i capture in mjep the picture quality is really bad!!
– DVPro capture has drop frames!!!
– When i render clips, they change a liitle bit of croma-level!

Really really bad 7.4 driver (many of those problems i had also with 7.2 and 7.0 driver)
I tried 7.4 with Premiere Pro 4.2 in Win XP and Windows vista and Windows 7… on different Mainboards with 4 different Decklink Cards and different grafik cards…difeerent RAM and even with Sata Controlle or without Sata Controller different Hard disks!!!! In any configuartion i had the same problems!!!!

So please Decklink guys, don´t tell you never heard about
some of this problems!!!
And please don´t ask me about my configuration (it alway the
same question) i use recommanded boards…latest driver and so on.

So just work a little less with your davinci and make decklink
now work!!!!
For the moment is stepped back to PPro 2 and 6.4 drivers.
This one work okay (exept the DV Problem!)
I am really tired about testing your drivers…

Hi Guys

I am from the European support office for Blackmagic Design.

These aren’t problems that we have had reported to us so far, however I would be happy to look into them for you, and ensure that any problems that do exist are addressed.

Please feel free to contact me directly at:

support-emea@blackmagic-design.com

and we can begin looking into the problems you are experiencing, and see if we can help in any way.

I also emailed Decklink support about the MJPEG quality issue and they replied a month later that it’s a known problem and that they are investigating the issue.

I wonder how the European support knows nothing about it.

Hey Tony

We’ve actually been working through the problems mentioned in this thread and we are still running through them. I didn’t spot the MJPEG thing on first glance, that’s my bad, but we are aware of this particular problem, as are our engineering team.

As an update for you guys, the issues with laying off to tape being out of sync has since be raised to our development team, and they are looking into it right now. I know a couple of people have contacted us directly after my post, and so we will also be looking into possible work arounds in the mean time.

We are still running through Claus-peter’s issues, and some of these appear to be the way Premiere works (ie having to re-render effects on a sequence after duplication), and some of them are not the way it is supposed to function (ie when using BMD timelines, you are only supposed to use the Decklink serial control, our driver is not really designed to use the system serial ports)

Hey Guys

Today we have posted new drivers for our capture cards, Decklink 7.5. These are available from the downloads section of our website here:

https://www.blackmagic-design.com/support/software/

So far, we have not seen the audio sync problem mentioned above with these drivers, so anyone experiencing this problem should update to v7.5. If you experience any problems, or need further assistance please get back to me either here, or at our support address!

Have a very Merry Christmas guys!

The 7.5 drivers fixed my out of sync issues when exporting to tape.
