One thought:
If it works in SD, but not in HD, it might be that the chosen slot on the motherboard, is not running in x4 mode, instead in x1.
Try swap slots to see if that makes a difference.

DirectShow API: no, there is nothing to check.
Hardware config: I would not run WATCHOUT 5 on this. Too low spec.
What kind of graphics card is used?
Which driver for HDExtreme?
Are we talking about Preview in the Stage Window of Production OR capture in a Display computer?

Thanks! ;-)
Yes, it's possible, at least HDMI, maybe analog component,
I doubt it work well with analog composite, if at all.

Hi Leonard,
With almost no info on hardware/software/version, it's impossible to tell.
Looks like a Windows driver or service not turned off properly, though.
Please file a support question at support@dataton.com with the relevant info attached.

Hi Neil,
Out of Osprey 230 and Intensity Pro, Intensity Pro is the better choice.
It's faster than the Osprey, but still slower than a progressive, digital capture card.
Most settings in the driver, can be left alone, WATCHOUT do not use them,
instead capture is done through the DirectShow API.
The main thing to use the cards own capture software for, is to see if the signal is
present at the cards input, before capture test in WATCHOUT.
"Because I have to capture a PAL source would I be better to run WO at 50fps?"
It might be, but setting WATCHOUT to 50Hz, without using an EDID on the output at 50 Hz,
will not help much.
Capturing interlaced, analog LIVE signals, will never be as good as a progressive, digital signal, HDMI or HDSDI.
1280x720p, HDMI or HDSDI is a good choice here, cards are not so expensive, not cameras either,
at least not HDMI-based ones. There are HDSDI-cameras from 4-5000 USD, an example is Canon XF-105.
1920x1080p (3G HDSDI) is still a bit out of reach for mere mortals, otherwise it's the best solution.
Even 1920x1080i, interlaced, digital (HDMI or HDSDI) is better than standard analog video, composite or component.
Interlacing artifacts & tearing can of course still be visible, especially in fast movements.
"anything I could do to improve the delay time?"
Not in the settings in WATCHOUT, no.
The delay in WATCHOUT from input of capture card to the output of the graphics card,
on a properly configured system, is approx. 2.2 frames, assuming a digital, progressive signal.
Osprey and Intensity with analog, interlaced signal, is slower.
I don't know by how much, though.
Using progressive, digital will of course help.
Any devices inserted in the chain between camera and capture card, will affect the delay,
for example a vision mixer.
Hope this helps,

Hi Michel,
Although we do not recommend using MacMini:s or any motherboard/integrated based graphics solution,
it could and have been made to work, for some basic needs.
Have our guidelines for Windows 7 setup been applied here? (enclosed)

WATCHOUT, Add Live Video
Input device 3, Component, :1
Size: 640:480
Video Standard: should be NTSC M
other is ONLY used for RGB Computer source input
Deinterlace: should be Best Quality

What is the source signal, in Media Express?
What settings chosen in WATCHOUT Live input settings?

Hi Roger,
Isn't this a question to ask Barco?

And this card has 2 "legacy" outputs, DVI and/or HDMI, and 2 MDP outputs?
Then I think I was correct earlier, that if three outputs is connected,
and two of those are MiniDP, they will both have to be ACTIVE.
OR, one have to use the 2 "legacy" outputs first, before using MDP outputs.
This is more a Windows setup issue, than a WATCHOUT one, I think.
WATCHOUT does not run in the same graphics mode that the Windows desktop do.
"when I connect the Watchout App from the ipod (the way this installtion is operated) the third output (now the HDMI one) drops its sync signal monetarily, causing the projector to drop out. This only happens when the ios app connects, and then it returns back again"
This I've never heard of before.
As always, if you require more detailed research, please compile as
small show file and send it to us, at support@dataton.com

If the adapters are truly ACTIVE, then there is no limitation that I'm aware of.
The only thing that seems a bit hard to find, is the ACTIVE MDP -> VGA adapters themselves...

Some questions:
- why three outputs connected to the card, if you only use two?
- which AMD Radeon HD6950 card specifically? They are not all the same...
- 1 x Mini DP to DVI, this is the ACTIVE adapter?
I would guess that if three outputs is connected, and two of those are MiniDP, they will both have to be ACTIVE.

Just to state the obvious, ALL projectors throw light when showing a black image.
LCD technology is inherently worse than DLP in this area, especially high-brightness ones. (that was you I meant, Sanyo... ;-) )
Color/brightness uniformity over the image area and using wide-angle lenses also affect this.
Using projectors with built-in edge blending capability, could be better,
if there is Black Level Compensation for the areas surrounding the blend.
One thing though, there will be a hard-edge issue between these areas, that has to be dealt with, too.
Only way to get a "real" black is, as suggested above, to use projectors with real shutters or external ones.
Nicest is to use a dowser/dimmer type like in Barco HD8, this gives you dimming instead of a straight cut.
Both ways will of course give you total blackout.
Good thing with WATCHOUT is, that these can be controlled from within a timeline, if needed.

Hi Lloyd,
Since black is "a little light" no matter with which technology you project with, it will always be a
"black level build up" in the blend area, there's no easy way around that fact. DLP technology is still
the preferred platform in this regard, I think. LCD technology:s black level is better these days,
but not on par with DLP.
There are of course ways to counter this issue, some more expensive than others:
- using special processors, that can raise the black level of the areas surrounding the blend.
Used in simulators and similar areas, often combined with warping tools etc.
One example can be Projectiondesign:s MIPS-boxes. This kind of solution is not cheap.
http://www.projectiondesign.com/products/multi-image-processor
- old school way, it's optical blending by placing masks, mechanical or optical, in the optical path of the projector/s.
This is a simple, in-flexible solution to the problem, but it will give you a complete "black" level.
Could be cheap, but not so easy or practical to implement/use.
An example : http://www.barco.com/en/simulation_virtualreality/product/1451
Hope this helps,

Some thoughts on this subject:
- Always use audio for video files, separated from the video file for better stability/reliability.
Preferably .wav-files
- .mp4 with embedded AAC-audio or AAC-audio is not supported within WATCHOUT:s codec.
- QuickTime is not involved in the playback here, hence if it plays in QT Player does not tell you anything.
If the file plays in Production but NOT in a Display computer, there must be a difference in what codecs
that are installed.
Recommended is to ONLY install WATCHOUT and latest QuickTime and turn off Windows
Media Center Features. All other installed codec-packs, DVD or Media-players will potentially affect
stable WATCHOUT playback.

Hi Daniel,
I would recommend you to NOT use Adobe Encoder.
Instead use a separate encoding program as it gives you many more options
and yields a better result for WATCHOUT use.
Some suggestions:
- Telestream Episode 6 (MacOSX/Windows)
http://www.telestream.net/episode/overview.htm
- Grass Valley Procoder 3 (Windows only), a bit old now, but generate good results still
http://www.grassvalley.com/products/procoder_3
- TMPEnc (Windows only), freeware/commercial versions available
http://tmpgenc.pegasys-inc.com/en/index.html
http://www.tmpgenc.net/en/index.html
Please also see the enclosed document for some guidelines on settings and codec choices.0 -
What is your capture source input actually?
What is it you want to achieve with 50i/25p/50p, that can't be done on 60p?
Internally WATCHOUT works at 60 fps.

You'll need a sound card with drivers that works with multi-channel, under Windows 7, with DirectX/Direct Sound.
There is a major difference between WindowsXP and Windows 7 in this respect, and manufacturers has not kept up.

"I had converted the video from animation to h264 becouse the card are gts 270..."
The choice of codec has NOTHING to do with the choice of graphics card, it's not decoded there.
"if it's correct i need an adaptators from 1 minidp to 2 dvi?"
NO, you'll need one ACTIVE adapter from DisplayPort/MiniDisplayPort PER output.

This is true ONLY for outputs OVER 2 , as described here:
http://dataton.com/forum/topic/93-wo5-multi-output/
"The card has 2 DVI, 2 minidisplay and one hdmi"
Please note that out of these 3, legacy outputs, ONLY two can be used at the same time.

it doesn't say it active, like here:
http://www.cableclub.com/mini-displayport-adapter-c-667.html
So they are NOT active.

Preview (in WATCHOUT) is only possible on the Production computer, with a identical capture card present. On Display there is only capture, hence my question.
If this does not work, please file à report at support@dataton.com instead.
