  1. Just to share a personal experience : did a project recently where I received all footage with AAC audio embedded (despite the named document which I provided as guideline). Besides one strange artifact during programming / rehearsal, all footage worked perfect with AAC audio.

    Display system AND production system we're completely configured as per WO guidelines with no additional codec pack or any media software installed. Somehow, AAC is supported by a standard win7 install I guess (well, it must be). Perhaps wmp supports this? Or qt?

     

    I will keep holding on to the specs as described in the 'codec' document, but can't help but wondering ....

  2. Blackmagic does a pretty good job with their mini converter, as does Aja. (Up/down/cross).

    I know their faster as for instance an image pro. Will be doing some detailed testing on this in near future, also curious about BM dvi extender for instance. While I'm at it, I want to test several optical fiber units we have in stock. It's a bitch that manufacturers keep so silent about latency's. if known, it's hard to find.

  3. Hey,

    Specs seem ok, but note : amount of ram isn't as important as the ram configuration (dual / triple channel) and CAS latency. Also, for playing several hd streams, you really want to use 2 x ssd in a striped raid config! Also the good remark from geogen about the capture cards, you really want to go hi end on this. It's all about using the right components for optimal (and stable) results.

    Compare costs of a well tuned high end WO system (at least 4 to 5K with class A components and 2 high end capturecards) to a decent 3chips projector. In that perspective, you don't wanna cut your budget here, do you? (Even compared to the inferior budget projectors like clm hd6). Once customed to all watchout's great features and capabilities, you'll want to go all the way with the system!! Last thing you want is being held back by the weakest link in your hardware config.

     

    You're welcome to have a look at our systems in Amsterdam, perhaps you could match systems and we can crossrent to expand setups with similar systems ;-)

     

     

  4. Hi Jonas,

     

    thanks for answer. i probably have to go the hardware way like http://www.tvlogicusa.com/product/product.php?model=TDM-243W

     

    cheers

    Nice monitor!! But i'm sure you'll be able to find cheaper solutions. There are devices (hard to find though) that will convert the left and right signal into a combined active signal (either l/r, top/bottom or stacked frames). If i find the right hardware (cheaper than the obvious Miranda solutions) i'll let you know, please do the same for me!! (Sick of testing with to polarized beamers). ;-)

  5. Question @ jfk

    You mention "If anything, it adds to it ever so slightly, as the captured signal is 'shaken' to match reference."

    But given the fact that the camera's CCU is using the same reference, am I right that though this addition of delay would not occur, it won't contribute to a lesser delay either? (No so theoretical effect at all?). What relation is there between the clock of the capturecard and that of the graphicscard? Any? Does either influence the other?

  6. Not sure what Jonas will recommend, but for my personal experience: used a i5 laptop last major show (yesterday in London) and had no issues at all. Of course system was tweened according to guidelines, performed great, even with numerous hd streams previewing in the stage area at hq. (hp probook 4740s, so not even an high-end system). Normally i always use one of the display systems to have the live video and data preview, but had to use all of my systems as displaysystem (needed almost all of the outputs).

  7. Uhm, guys, not sure if you're talking about live video content (probably not since signal is coming from an AW Opus), but if so, i would avoid using interlaced signals because of delay caused by deinterlacing. 720p usually looks great, specially on video. Graphics could of course always be 1080p, but tben i suppose you'll use dvi / datapath anyway (BM is more video from my pov).

  8. Hmmm, no, that wouldn't work either. You basically want the video flown in with a still first frame and start to play once in place? Then, yes, just stick to exporting the first frame as still for this. How easy can it be, right? (you could use pre roll as long as the needed animation, do the position tweening on this and copy these tween points to the still cue (so you don't have to fiddle around with position, it's exactly as is)

     

    Or am I missing something here, guys?

  9. Pause cue might work, but it has risks. Also depending on codec used. For instance, recently I did a 3D presentation where content was supplied as png sequence. (22 slides with 40 moving animations (and 40 stops). They had only 8 sequential stills or less per stop. Soon found out that using mpeg2, no matter which GOP structure, was a pain in the ass getting the pause cue's right, leaving the correct still displayed. Finally turned to h264, with full keyframe on each frame. Bit more processor intensive, but did a perfect job.

    But using first (few) frame(s) of video to start of with you might risk the fact that WO won't load video. I guess if you made sure that video is edited with at least 3 seconds of still picture embedded, you should be safe. Preloading video by using preactivated aux timeline is an easy tool.

     

    Using an exported still of first frame is always the safest way to go. Simply assuming you can use just a pause cue is not enough...

    But why haven't you just tested this yet? I always extensively test ALL chosen solutions before even starting to designing and programming the show, so I always have enough time to solve any upcoming issues. Hate to solve these issues with a client breathing in my neck. I strongly feel that my client deserves a calm and worry-free (pre)show.

  10. Hi Fabios: did you ever manage to use more than one input at a time in another program than WO with this card? I have those cards in both my Mac pro editing station as well in my WO systems and you are supposed to select 1 type of input in the BM configuration panel. (doesn't auto-sense like H264 recorder from BM) So it's just the design of the card that puts the limit on it. If card was able to select and recognize / process multiple inputs at a time, WO would be able to use all of them too. (i.e. with the SDI DUO or so).

  11. Geogen, how is the LCD technology working for you using Christie? In my personal experience I found any LCD projector inferior (even 3-chip versions) in terms of the lack of blacklevel and thus low contrast ratio's. Our company only uses 3-chip dlp for anything over 6K A.L. Not only because every shoot-out points in that direction but most of our clients request for it in their RFP's.

     

    I'm curious about your experience in this.

  12. Thanks Tobi,

     

    I'll give it a try when back in office. Noticed a .jar files : for which platform is this?

    But if not manually (since then I'm sure it's correct and I'll have a better grasp of the setup, as oppose to automised) I tend to use one of the smartphone apps Projectionist or WScreenPro. The last one provides media server settings with offset in the watchout colors. Perhaps coincidental or not..?? ;-)

     

    Have you tried those yourself?

  13. Don't buy the 101V!!!!

    Not because it's not okay, but because you should then buy the 101D : this one works on both digital and analog signals. Simply use two dvi-i to VGA adapters and you've got an analog solution. More value for money I'd say.

     

    Btw: the lightware EDID manager is almost same price and covers more resolution (but you'd probably won't need them)

  14. May I suggest a simple test : change your display addresses, in order to switch the working pc (1) with the not-working pc (2). If the problem still occurs on the same pc (2) with different media / config running on it, it's almost certain caused by your hardware. If the problem moved to pc (1), then it's more likely to be a bug in the WO show.

     

    Just make sure you clear all caches and shows from the pc's after switching addresses.

  15. Alex,

     

    Yes, you are right, EDID managers / emulators, do just that. But you're monitors are capable of this res / framerate, but it's not their recommended EDID. I've experienced numerous times in numerous configurations, when outputting normal resolution, like 1080, the graphic cards software utility doesn't allow you to set the required resolutions even if the monitors / projector allow it without dedicated EDID's.

    Using hardware EDID's is a simple, very effective and cost-efficient tool!

    And even if you just want to know for sure if your card is capable of outputting multiple outputs at 50hz, using the EDID's to test this is THE way to

    go. And they are cheap enough, in my PoV extreme value for money (you couldn't care less where your signal is going)

     

     

     

  16. Is your source showing in the BMD software? (media express). If not, sort this out first. (use of a HDFury might do the trick) If so, any more live feeds installed? Perhaps correct the input number. Also, set the correct format in the live video settings.

    Just to be sure : you're talking about a feed into the display machine right? (so will not appear on production software if signal not inserted into that machine.)
