Hi Brian,
I had a look for the Lumenera camera on the internet and it does appear to be directshow compatible so it should work fine with UFOCapture.
One thing you need to remember to do before running UFOCapture is to run the file install.bat found in the program folder. This installs the directshow filter which UFOCapture uses.
If you have already run this file and it is still not working, you could log a suppport call with Lumenera and ask them for the latest directshow compatible drivers.
Hope you get things working!
All the best, Robert.[/b]

Hi Brian
Generally, DirectX directshow interface is very complicated.
Modules of directX(driver,system,UFOCaptue) negotiate each other at the begging of execution to find an compatible interface.
Frame rate, inner media type(pixel format), frame size are the key.
When all modules agree with the parameters, then execution become possible.
"UM012" means there are no parameter set which all modules can handle.
I know very little about Lumenera Lu075 cameras, so I cannot say it is compatible or not at now.
If it supports only 60fps, then it will be supported by UFOCaptureV2 only(UFOCaptureFee or Pro does not support 60fps).
But even UFOCaptureV2, it supports only 16bit pixel format(YUV,I420,UYUV....), if Lu075 has only 12bit RGB format(36bit/pixel), there is no hope.
There is some possibility that UFOCaptureV2 can work with it. Please try UFOCaptureV2 at 60fps below (it has another 30days trial period).

(I am afraid that 60fps may double the CPU load. Please watch it.)

My Lumenera camera may not work then. The monochrome version I use is supposed to have 12bit uncompressed output rather than 8bit compressed like regular webcams, which gives you a higher quality image. I'm already trying V2.05 which isn't working. When I use the camera to image the planets, I've got a program which I bought with the camera called Streampix. http://www.norpix.com/streampix.htm
It allows me to change the bit depth between 8bit and 16bit, and the exposure from .001s to several 10s of seconds. 1-60 fps. For a $450 software package it still doesn't do what UFO Capture V2 does. Which is what I need.
I've been looking at the cameras you guys use which give you pretty good images but the cameras have an analog output. The freeze frames appear to have every other line missing, like an interlaced TV picture. I may have to find another type of USB 2 camera. Any recomendations would be appreciated. If there is a way you could make my camera work with UFO V2 that would be great. If I could provide any information that would help, let my know. I wish I was a programmer for situations like this.

Thank you for information.
Well, I recommend to use interlaced cameras like WATEC WAT-100N and analog capture boards.
I think there may be 2 ways to use Lumenera camera. (it seems very difficult though)
1)Someone write A directX driver program of Lumenera camera which use UYUV 16bit/pixel format.
2)UFOCapture support the format which Lumenera camera uses.
We use analog interlaced WAT-100N because we were thinking that it is almost the only one which we can obtain satisfactory results of night sky motion detection.(except I.I.)
Different from taking still image of the planets, the sensitivity of the moment and S/N is very important.
If the Lumenera camera is good enough to replace WAT-100N(which is used by most of us in Japan), I will think about 2).
Would someone please show me the full rate(30fps or more) movie of night sky which is obtained by Lumenera camera using wide lens(45degrees of FOV or wider)?
I know USB camera shows good performance in very narrow observation such as planets, but I have believed that they do not have enough sensitivity for wide area motion detection in night sky.

Hi Brian Howell
We do not use any compressors during capturing. Because....
1.Post processing tool UFOAnalyzer is designed for un-compressed video.
2.Compressors increase CPU load and sometime they make PC unstable.
3.Image quality and time-domain accuracy will decrease.
We re-compress the captured avi when it is needed.
All movies on this forum are re-compressed ones.
Here is another sample.
This 2.86sec video was captured in non-compressed avi format (originaly 52MB).
Re-compressed by wmv codec which is included in Windows MovieMaker2.

Oh!! I mis-understood your message completely .
I have no intention of putting your video clip to UFOCapture.
I just want to know the sensitivity of your camera.
Thanks.

Quote: | How is it that an analog, interlaced CCD camera is far more sensitive in darkness than my expensive digital CCD camera?? |
Some high sensitivity cameras such as WAT-100N has video amplifiers in it.
It has 20 to 40db gain, and amplifies the output signal of CCD.
Quote: | Also, since I may have to alter my plans to use my Lumenera for realtime video, I may still use it for high quality longer exposure imaging. I visited Watec's web site, I saw on their homepage that they have a newer camera the WAT902H2 at .0001 LUX. If I were to buy a Watec camera, is there a reason for using a WAT-100N? It appears that everyone is using a Neptune 100 even though the WAT-120N is .00002 LUX,and the new WAT902H2 is .0001 LUX. |
Yes, I recommend WAT-100N by 3 reasons.
1.WAT-100N has manual gain controller, you can tune appropriate gain and S/N.
while WAT902H has too much gain and the video becomes rather noisy.
WAT-120N is time domain stacking camera(like slow shutter camera) and is not suit for real time motion capture.
2.WAT-100N can be set as gamma off (=1.0), it enlarges the contrast of dim objects.
3.WAT-100N lens mount is physically compatible with CBC F0.8 lenses. While WAT902HS2 is not(too narrow mount inner space for the optional IR correlation lens of CBC F0.8series).
Be aware that WAT100N has unique auto iris pin assignment. It is not EIAJ standard. You should modify the iris cable when using normal auto video ires lenses.

Hi Brain
Quote: | 1:Could you provide a little more info on the correcting lens and the spacer for the correcting lens you have listed |
Well.. the correcting lens is optional lens of CBC F0.8 series, which improve the sharpness of infra red lights when using monochrome video camera. It is bundled accessory of CBC F0.8 series lens. See a picture below.
In this picture, I use WAT100N with CBC HG0808FCS-L DC iris lens and iris conversion cable HC01.
About HC01 see the page below.
http://www.watec.net/english/accessories_top.html
Quote: | could you explain a little more about the contrast improvement filter you mention? |
We do not use any filter recently. Because we found the light loss of those filters cause decrease of capture a lot, though improvement of the sharpness is a little.
Quote: | 2: I was looking at the page containing video of Sprites. I see the WAT-231S was used. On Watec's web site they have a WAT-231 and 221. The only difference I see is the CCD size 1/2 and 1/3. The Neptune 100 has a 1/2 CCD, the WAT-231S used has a 1/3 CCD. I was curious as to why a WAT-221 was not used since it has a 1/2 CCD like the Neptune 100? Is there any benefit to using a 1/3 CCD? |
No, there is no special reason. 221 will bring wider view. Sensitivity may be same.
Be aware that the sensitivity of color cameras is about 1/100 of monochrome cameras.
Quote: | I've also been looking into capture cards. Everything I do now is digital to start with so I'm not up to speed on analog to digital capture cards. You use an ELSA EX-VISION 500TV. I haven't seen this offered anywhere, I guess it's no longer made. Most of what I see is analog to DV or MPEG 1/2. Do you have any recomendation on a high quality card currently avaliable? |
I recommend software encoding PCI video capture cards.
UFOCapture uses Microsoft's DirectX Direct show video capture interface. It is same with Microsoft's Movie Maker or Media Encoder. Ask dealer whether a model is compatible with Windows Media Encoder.
There are many models which is compatible with it,some hints below.
http://sonotaco.jp/forum/viewtopic.php?t=544
ELSA EX-VISION 500TV is very old one. It becomes EX-VISION 1700TV(PCI) now.
I
ADVC300 will work with UFOCapture. Even ADVC55 may be enough. But I don't recommend these IEEE1394 capture equipments, because they have non square pixels and the CPU load may become very high.
Quote: | I would really like to see if something is available to convert the interlaced video to progressive, I hate that interlaced look of the analog video. |
I agree with you, but I think it will take at least a few years before we can use HD or progressive video captures.

Thanks again for answering my questions, you have been a big help. The picture you posted was most helpfull.
Since I'm having to start over again from scratch, I'm trying to get up to speed on hardware as fast as possible. I'm probably going to buy my equipent from here: http://www.astrovid.com/imaging.php
I'm not sure if the CBC lenses come with a correcting lens or not, I'll have to find out.
http://www.astrovid.com/products.php?cat=170&pagenum=2
You mentioned I would need to modify the cable to the lens, does the HC-01 or the AIC plug replace the manual modification needed? Or is the modification completely seperate from either of those accessories?
Thanks again,
Brian

When using DC iris lens such as HG0608FCS and HC-01 + WAT100N, there is no need of modification.
Because HC-01 is a special iris type conversion cable for old WATEC(non EIAJ) cameras.
When using video iris lens such as HG0608AFCS with WAT100N, then cable modification is needed.
You should exchange pin 2 and pin 3. You may do it by cut and reconnect the iris cable, or using new AIC plug.
I think the IR correction lens is always bundled with the F0.8 lens by manufacturer, but I am not sure....

A quick question on UFOCapture and CPUs. Before I finally get my observing station built I may buy or build a semi-dedicated computer for capturing video. Something like the following:
http://global.shuttle.com/Product/Barebone/SN27P2.asp
Is UFOCapture capable of taking advantage of dual core or 64 bit CPUs? It would be great if the capture and processing load could be distributed between the two cores in the dual core processors.

Hi
UFOCapture is 32bit application now. But It uses many threads simultaneously. So HT or dual core is very effective.
More over, we are testing dual-capture (simultaneous two channel video capture by one PC) now. Next version of UFOCaptureV2( V2.09 or later) will have ability to do it .Though the possibility depends on the combination of the capture cards or other hardware.
Therefore now I recommend latest dual core computers for a new machine, such as CoreDuo > 2.0GHz, Pentium4 HT/dual >3.2GHz which has two internal fast HDDs.
The PC you pointed may have enough power, but I am afraid that it has only one PCI slot and only one HDD.
I recommend normal desktop (middle tower type or larger) which allow 2PCI and 2HDD.

For a dual capture setup are you using the ELSA capture cards (two of them)? I've done a couple of searches and haven't yet found a reseller here in the states that sells ELSA cards, such as the EX-VISION 1700TV(PCI) you mentioned before. I'll keep searching though.
Thanks

Quote: | For a dual capture setup are you using the ELSA capture cards (two of them)? |
Yes. There are two ways.
1. Use two same cards which support simultaneous multi capture such as ELSA 1500TV or 1700TV.
2. Use two completely different cards which the drivers might not interfere each other.
(ex. one card uses Phillips 713x and the other uses Conexant 2388x)

It seems that ELSA 1500TV or 1700TV are sold only in Japan. But there are many similar products that support DIrectX Direct show interface.
Most of the recent PCI video capture/tuner boards for Windows which does not contain hardware encoder will work with UFOCapture. Search whether the product support Windows MovieMaker or Windows Media Encoder.
