Error: Failed to build a preview graph

[broadie]

I have installed Video Studio 9 and all went well. Hooked up to my Panasonic DV recorder NV GS150, got control of the camera to capture video but then an error message came up "unable to switch to capture mode" "failed to build a preview graph". The tape seems to be running and caputring but there is no picture and when I save it, there is no picture and it wont allow play back.

Broadie,

I have exactly the same problem. Don't have an answer for you but if I find one I'll let you know.

Hope you'll reciprocate if you're successful.

Use the Search function of this Board (see link in my signature) and set 'preview AND graph' as the key words, and Video Studio as the Forum. That will provide a number of possible answers to your problem since you otherwise don't provide us much information about your system or capture device and source that we can work on.

Thanks for the help guys. I got a reply from Ulead and it does not look good for anyone wanting to capture via USB using Video studio 9. Seems a backward thing for ulead to do. Not sure if I will return the product yet, use another program to capture or get a firewire card.



REPLY FROM ULEAD

I'm sorry VideoStudio only supports capturing from a DV camcorder by attaching it into computer's DV-IEEE1394 (firewire) port and not by USB. But we will improve that in the future versions. We understand that some camcorders supports both USB and firewire port in transfering video in the computer in full digital quality. However, firewire was designed for video and like VideoStudio, most software supports firewire. Also, you will not be able to send your video from the computer back to the camcorder except over firewire. So, that is why I and most video makers continues to recommend the use of firewire instead of USB.

Or, you can use your other capture program to capture the video from your camcorder using USB port then import it into VideoStudio to edit.

Broadie -- in reality, Ulead's reply to you is generally correct. I know your camera has a USB 2.0 port and that this should have the speed to transfer high quality DV. But the camera also has a Firewire/i-Link port and if you look at the specifications this is designated as being for 'DV in/out'. Apart from a handful of cameras, USB 2.0 ports are still mainly limited to transfer of web-cam quality video (and still photos). The problem is that no camera manufacturer of which I am aware includes a Firewire cable with the camera. But if the camera has a USB port, you always get a USB cable and this naturally gives rise to the false impression that this is what is used for transfer of DV...

Thanks for that - I totally agree. No firewire cable with the panasonic camera. Managed to get a firewire card and cable from Ebay and look forward to DVD movie making soon. Thanks for all the help.
