I am using the Hauppauge USB-Live2 capture device for presentation recording. The OS is Win7 64-bit. Because Vidcap and Amcap are not compatible with the OS, I'm using NCH Debut for basic camera tests and monitoring, and Panopto for presentation recording (http://panopto.com). The video signal is PAL-B.
With Debut, the camera images are beautiful. However for whatever reason, the images are not good in Panopto. There is an artifact that I would call horizontal 'banding' whenever something is moving in the frame (or when the camera moves). This banding is present both in the preview and the recorded images. And I have documented the same problem on two different PCs with different PAL camera sources and different USB Live2 capture devices.
Here is a document with screenshots (http://itr8.com/hosted/ftp_guest/nafa/panopto_troubleshooting_screencaps_rev2.pdf) and a short video clip (http://itr8.com/hosted/ftp_guest/nafa/banding_error.wmv) both of which illustrate the problem.
I know this is a bit off-topic for Debut forums, but please help with suggestions if you have had any similar experiences. Thanks!
