Hello!!

I have to say that your programm is very super!!

I am using your trial version and i have one problem....Sad

I have 3 Watec 902DM2S in a Pentium 4, at 3 GHz with 2 GB Ram.
To connect the cameras with my PC i use the Kworld DVD maker usb2.0 which is a video to usb interface.

[I don't know a lot from computers ok!! Laughing ]

Can somebody tell me how can i use my 3 cameras together in the same computer?

i can open 2 times Ufocapture and operate 2 cameras
but when i open for third time the programm it says that

UM021 media type or resolution not matched

What can i do??

Thanks a lot,
Nikos

This message usually means that the Xi,Yi setting or device assignment is not correct.
It seems there is parameter confusion.
Parameter settings of UFOCaptureV2(include device name) are saved as "settings.ufi" file in the execution directory.
To operate multiple devices simultaneously, it is needed that the execution directory must be each for it.
At least, you should copy and make three execution directory. Have you done it?

Though UFOCatureV2 have ability of simultaneous multiple operation, it depends on many factors.
Combination of device, performance of PC, HDD performance ..... It is very delicate.
Many device drivers are designed only for single operation.
I don't know Kworld DVD maker usb2.0, but there is possibly that its driver has some limitations.

Here are some person who operate 3 cameras on one PC simultaneously, but it is not recommended for all.
I use 3 PCs to operate 6 cameras.

Thanks for your advice SonotaCo,
here is what i've done.

I have tried 3 different programm files with different save setting.ufi from each one.

Nothing....

Size at 640x480, Fps at 29 and at 25.

I could only run 3 cameras simultaneously when i used two Watec and one web camera..

Something is happening with my analog signals in my video to usb interfaces....

A lot of days the same problem,
i do not know if i must find another way to connect my cameras with my PC...

Any idea?
Or everything else, i don't have a problem.... Very Happy

Well, if the setting file problem of UFOCapture does not exist,
then it may be the problem of the device driver of Kworld DVD maker usb2.0.
It is the product of hardware manufacture and is not controllable.
I think you should give up triple operation by Kworld DVD maker usb2.0.
Most of capture device drivers are designed for only single operation.
Therefore we are seeking the combination of devices but it is not easy.
I think the combination of two Kworld DVD maker usb2.0 and one IEEE1394(such as Canopus ADVC55)
may have a little possibility, but it may require very high CPU performance.
It will require Core2Duo 2.4GHz or higher .
In my experience, dual or triple operation sometimes become unstable.
I recommend to use another PC. It is easy and reliable.

Why there are two Fps ? Do you use both PAL and NTSC cameras?

Hi SonotaCo,

I use only NTSC cameras but i adjusted Fps to see if it works in 25.

Ok untill i find something,i will use only two cameras.

I looked up for Canopus ADVC55 and it was a liitle expensive,above 300$.

Can you think something else for IEEE1394?

Sorry for my questions but i want to catch a lot of fireballs, xaxa Laughing

Hi Nikos,

If you have 3 USB capture cards (such as KWorld) then you are using 3 USB ports. These 3 ports are not necessarily using a different USB bus, they may be sharing the same USB bus. Because of this, you may be running out of power or bandwidth on the bus. Try using different ports on the computer or maybe purchase a PCI card which has more USB ports. If you have 3 PCI ports free then I recommend the Osprey 210, it is the best card I have used so far. Robert.

Thank you Robert,
i will try from next week to put on one pci card with usb port on ( does this exist?? Cool )

and then i will tell you what happened.

Sorry for my bad knowlege in computers and in my English too as i found out now... Embarassed

Tomorrow i wll see what is going on with my USB bus and i will try to connect the Kworlds in different USB buses.

See you again SonotaCo and Robert.

Greetings from Greece,
Nikos

Ah you are from Greece? Please try and contact Apostolos Christou, aac [at] arm.ac.uk . I think he is using 3 capture devices in one PC. He will give you advice, but he is very busy working on meteors, so give him some time to reply! Robert.

Hello every one.

i have changed my equipment,
and now i have 2 Pinnacle 710 studio plus usb and 1 Kworld,
and i have some problems...

Pinnacle works with 720x576 size and you work it in Pal B

So i have a problem after a black out

So lets take it from the start,i
activate the first camera with th Kworld at 640x480 NTSC,
after i activate the second one with the Pinnacle and it says that i must re install ax,
ok i do it.

But when i try to activate the third it first it didn't do anything,
and after it wrote that my settings were very old,and that i should register again.

I did all those and nothing,
when i activate detect, it dont't give me any video source there where it says :
1 Composite
2 S-video etc.
And when i try to click over the button 'Set: it stopped!

So now i should try to reinstall the Pinnacle.

any ideas??


Clear skies,
Nikos

Hi Nikos
Well, I think your trial is very challenging.
There are many possibilities that make troubles in multiple device simultaneous operation.
1. device driver is not designed for simultaneous multiple operation.
2. USB channel bandwidth limit
3. HDD seek speed limit, transfer speed limit
4. CPU limit
5. config file (ufi) confusion
I cannot say which is probable on your case.
I can say only on some points.

> and that i should register again.
Registering is not needed if you can see the main window of UFOCapture.

>it says that i must re install ax
All instances of UFOCapture in one PC must be same version.
Then, normally, re install is need only once on one PC.
After once UFOCapture works normally, re install ax is needed only when
you change the installation directory.

>it dont't give me any video source there where it says :
>1 Composite
>2 S-video etc.
If the video source of second device is not shown, it is the problem of
device driver. the device driver of the hardware does not support multiple
simultaneous operation.

Sorry for my delay Sonotaco and other people here,but I was down in bed for a week.


Its very hard to discover what causes my problems.

For example tonight i changed USB places and after i re installed ax,
and now they are working all together.

Ok, but my problem after that is going to be that when UfoCapture detect by schedule i believe that it won;t give me signal from the 2 cameras with Pinnacle.

I am very disappointed some times with my effort.

Who nows?
