Thank you Zora from IPEVO. Problem fixed!

I’ve written about the problems when using the IPEVO P2V camera and Screenflow version 4.5 (20888).

The nice people from IPEVO got in touch and sent us out a new camera in super wuick time. Great customer service!

Recording video with P2V camera and Screenflow

As can be seen below, when we record the videofeed from the P2V camera and the desktop of the computer, with Screenflow it now works. Thanks Zora.

What changed? What was the problem?

(This is personal opinion. It might not help you.)

In order to find out what has changed between the old camera and the new replacement, I used the USB Probe utility in the OS X Developer Tools.

USB Probe allows you to investigate the technical details of whatever USB devices are connected to the computer.

There are a lot of differences between our old camera, and the replacement we were sent. In my opinion the information below are the main differences that will allow you indentify if you have the same problem.

I can confirm using Screenflow 4.5 (2088), OS X 10.9 (currently up to 10.9.3) and an IPEVO P2V (Device Version Number: 0x1128) you can record the camera feed, and the screen of the computer.

So, thanks to the great people in IPEVO. You’ve really helped. Now we can do usability tests again with our mobile testing kit.

If you’re looking for a great external camera at a great price for usability testing, I highly recommend the IPEVO P2V.
