    So to close this long thread, and to make it helpful for users with similar problem, here is the end of the story.

    In the end we purchased a Blackmagic SDI to Analog miniconverter. The main cable is in SDI, and we convert to Analog (Component in 1080i50) just before the projector (the last 50 cm).

    This solution works perfectly and we can now run in full HD without any problem.

    Thanks again to the Blackmagic team for their precious help and all the time Luke has been investing to find the solution.

    The current setup is now:

    I hope this can be helpful to others

    Regards

    Nicolas

    Note:
    If anybody is interested in a brand new Blackmagic HD Link Pro (just used for this thread’s tests) we haven’t been able to exchange it and will be looking at selling it .

    So in summary in an attempt to close this thread, and make it useful to other users who may have similar problems:

    Firstly, a huge thank you to Luke for his support and clear explanations. Having people like him definitely makes it much easier to work.

    In the case of my video setup, I came to the following conclusion (Luke correct me if I’m wrong):

  • There is a communication issue between the Blackmagic HD Link Pro SDI and the Projector Sanyo PLV-WF10. Both devices try to set the best resolution automatically, the resulting incompatibility gives a cropped image.

    • Ideally, for my situation, it would be perfect to be able to force the resolution output from the Blackmagic HD Link Pro (in this case to 720p50 or 1080i50) as when it is set that way, on the Panasonic AW-HS50E’s DVI output, the projector is working fine over DVI.
    Maybe an idea for Blackmagic, would be to release a firmware & utility software update which would allow forcing one resolution to the output if that be technically feasible. Luke any idea if that could be a possible BM update? 😉

  • On the projector, there is a component input that allows 1080i, I probably should try the Blackmagic Mini converter SDI to Analogue which should (at least I hope this time it would be the case as it would be the 3rd Blackmagic converter to be tested) solve my problem.

    • As shown below, using the component input will allow me to force the resolution of the projector to the same sent from the Panasonic AW-HS50E. The new connection would be:

    • Mixer: SDI out 1080i50
    • BM SDI to Analogue: component out 1080i50
    • Projector: Component in 1080i50

    As recommended by Luke, I will contact the closest Blackmagic Design support office (the UK in my case) to discuss the above.

    I hope this can also help other users to find the best BM converter for their use (as they are really nicely designed converters). (and maybe give ideas to Blackmagic’s fantastic developpers for firmware/software updates)

    Luke,

    here are the results of the next tests:

    The projector seems to set the resolution automatically without the possibility to change it.

    If I connect the computer directly to the projector (or the video mixer over the DVI output), I have a the full image on the projector and everything is ok:

    Projector: D-XGA (same resolution as when I connect the HD Link Pro or the Panasonic mixer)
    Macbook: 1024×768 (available: 640×480, 800×600, 1024×768, 1344×1008, 1600×1200) no “real video” format available

    If I boot my macbook in Windows, I have other computer resolutions:
    10

    • 24×768 cropped (heighed & width) Proj D-XGA
    • 1368×769 cropped h&w, Proj D-WXGAs
    • 1400 x1050 minimum cropped in width (just a few pixels on each sides) Proj D-SXGA
    • 1600×900 fine Proj D-UXGA
    • 1600×1200 fine Proj D-UXGA
    • 1920×12

    00 fine Proj D-UXGA (a few green pixels on the screen??)

    However on the above (WindowsXP), the image doesn’t cover all of the projector image (black around)

    My problem, is that the projector is setting the resolution automatically and doesn’t seem to allow me to change anything.
    On the other side, the macbook recognizes the projector and adapts the resolution but for some reasons, the HD Link Pro doesn’t react the same way.

    Regards

    Hi Luke,

    Thanks for your advice I set it all up and did as you suggested, but it still crops the sides (less than in 1080/50i) as you can see in the images below:

    the original image is:

    and this is what I get on the projector (horizontally 1 and 10 are missing):

    In this configuration I have:

    Panasonic AW-HS50: 720p output over SDI

    HD Link Pro (through utility):

    • Override Monitor’s Preferred EDID settings: enable
    • Scale video to fill larger display: disabled
    • Standard definition video scales as :1:1

    but for all the above settings, enabling or disabling doesn’t seem to change anything. I always get the same image on the projector.

    Projector:

    • DVI input
    • almost no settings possible on format

    Do you have any further advice I really would welcome your help.

    Regards

    Nicolas

    Thanks guys for all the valuable information,

    I’ve ordered a Blackmagic HD Link Pro DVI digital and was finally able to test it today. It definitely solves the issue of signal compatibility.

    But now I have a new problem. I have the image on my projector (Sanyo PLV-WF10) but it’s croping both sides (height is fine).
    I’ve tried:

    • downloading the Blackmagic software for the HD Link Pro to see if I change this, but without success.
    • I tried changing the output of the mixer (Panasonic AW-HS50E) but also without success. The only way I have found to have uncropped image is to go down to 576/50i but then it’s too low in resolution and I get a small image in the center of the projector.

    For reference, the mixer can send the following signals (SDI OUT):

    • 1080/59.94i
    • 1080/50i
    • 1080/24PsF
    • 1080/23.98PsF
    • 720/59.94p
    • 720/50p
    • 480/59.94i
    • 576/50i

    and the projector (DVI IN) can accept the following (from the user manual):
    DVI-I Terminal (Digital/Analogue)


    Any idea on how to fix this? I’ve tried pretty much every setting without success.

    So it doesn’t look like we have the same problem. But for me, luckily enough the os x 10.6.2 update fixed the problem. Everything back in order.

    well on this computer I can’t really downgrade and the other computer is old and slow…
    So I just have to hope some has a solution or that Apple will release a fix soon. I just upgraded a few month from FCP 3 to 6 and I don’t have the budget yet to upgrade FCP7…

    What kind of sound problems? Can you be more precise.

    On my side I am also experiencing sound problems.

    Since I upgraded to Snow Leopard, every time I try to export video that are >10 minutes long the audio just export as saturated sound after a few minutes.
    It seems to be due to snow leopard as when I plug the same hard drive and export the same project from my old mac (running os x 10.5.8 and the same FCP version) it just works fine.

    The computer failing sound export’s configuration is :
    MacBookPro 2.4GHz 2GB ram
    Final Cut Pro studio 2 (FCP 6.0.6)
    Quicktime 7.6.3 (630)

    I have been trying to export using FCP’s Compressor or Export/Quicktime movie or Export/Using Quicktime Conversion and they all give the exact same results.

    an example of a failed audio in a podcast can be found at: here the problem start around 1/4 of the movie and the audio looks like this

    Is it a similar problem to yours?

    Anybody experiencing the same? Any ideas?
