dropped frames capturing 1080i w/ Intensity Pro

[dvanoltri]

Hello everyone.

It is written on the blackmagic intensity tech specs that Dell stations are not supported. So, we (my collegue and I) were able to launch Intensity Pro on Dell PowerEdge T310 using windows 7 x64 instead of preinstalled Windows Server 2008, with drivers from Windows 2008 X64 Server. Driver version is 3.6.3. We have no problem when capturing 720p@60 but we have some frames dropped in record and translation (Video is going just right and then like goes faster for a part of second and then goes right again.) and audio (capturing with analog rca inputs) goes about 0.5 to 2 seconds earlier than video, depending on audio bitrate used, when translating or recording 1080i@50. Had anyone ever solve this problem? CPU resources usage is never higher then 40%.

Thank you for your help.

Try capturing to mjpeg. It has a much lower bitrate requirement. You may also want to try 3.4 drivers. Seems to be issues for some people with newer drivers.
