1080P/23.978 FCP Capture problems.

Posted by Bob Bridges on March 29, 2011 at 4:40 pm

I’m having big problems trying to capture 1080P/23.978 to FCP on my 15″ MBP via an Io Express box. The same combination captures 1080i/50 with no problems at all but when I set up a project for 1080P/23.978 the capture window shows a broken image that flickers between the input and, what seems to be, the last image that I tried to capture. During this time there is no, or a very distorted, out of sync image, on the output monitors (both SDI and HDMI)

When closing the Capture window, I have to refresh the A/V devices to get the FCP image to show on the Output monitors. Playing back imported 1080P/23.978 files from FCP is just fine.

If I get out of FCP and just use the AJA Control Panel sometimes the throughput signal is fine; sometimes I get an image on the SDI out that only has part of the picture or is vertically & horizontally shifted. Again, at these times, the HDMI output has no signal. Switching backwards and forwards between “Input Passthrough” and “Test Pattern” in the Control window results in a random selection of good images on both SDI & HDMI outs; no outputs on either or broken image on SDI and nothing on HDMI. The same things happens if I play with the Genlock options.

Reset everything to 1080i/50 and everything’s fine.

I suspect that my Io Express box may be having some sync issues with the 23.978 signal – but wanted to check here first just in case someone knew of a hidden checkbox that I’ve missed!

In case it helps, here’s my system configuration:
15″ MBP 2.4GHz Intel Core 2 Duo, 2GB 667MHz DDR2 SDRAM, OS 10.6.7
Io Express with 3/4 Express Card. v8.1.2 software and latest Firmware

BTW, I’m using a Blackmagic Design Decklink Extreme 3D card in a Mac Pro as my test source for both 1080P and 1080i.

You should probably contact AJA Technical Support for assistance. Are you sure that the output from your video source is actually 1080p 23.98 and not 1080PsF 23.98? Regarding the HDMI monitor; not all HDMI monitors support 1080p 23.98. Regarding the SDI enabled monitors; some of those only accept 1080PsF 23.98, not true progressive.

Again, I would recommend contacting AJA Technical Support to review your configuration, settings, etc. They can be reached via phone or email, Monday through Friday, from 9am to 5pm, PST.

Thanks for the quick reply. I’m UK based – is there a UK Technical Support team?

In response to your comments:

I’m using a Panasonic BT-LH1700W Professional monitor that indicates the resolution and frequency of the input and that is clearly showing that the input to the Io Express is 1080P/23.978.

The HDMI monitor I am using will show the image without any problem when the SDI output is clean.

Thanks again

While there isn\’t a UK-based AJA Technical Support center, you could contact the US-based AJA Technical Support now as it is still US business hours. Your AJA reseller in the UK can also likely lend assistance.
