JVC 720p50 + Kona LHe
I posted previously on this topic but I thought I would start a new thread as I have discovered that this is a bigger problem than I thought.
I am running:
Quad G5, Final cut 5.0.4, Kona LHe+KL-Box (drivers 1.2.2), JVC GY-HD101E (camera), JVC BR-HD50 (deck), JVC DT-V1710CG (monitor), JVC IF-Co1COMG (component card for monitor)
I am in Australia which is a PAL country.The problem I am having is getting the Kona Control panel to recognise the 720p50 analog component signal coming out of both the deck or camera. I have checked all the settings in the control panel and it is set to analog component in and the format is set to 720p50. I am not using audio at this stage. I have verified that the signal IS 720p50 because the monitor has no problem seeing it and states that it is getting that type of signal. This is before final cut is even being used, just the Kona control panel. The signal from the deck goes in to the Kona card fine when I upconvert it to 1080i (which the JVC deck does internally) but nothing at 720p50 (It states simply: ‘No Video’). I am at the stage that I am thinking that the Kona card must be faulty because everywhere I have read about the signals it accepts states that this should not be a problem. Could it be a driver issue? An issue with JVC’s signal? A problem that only exists in PAL countries? Has anyone else encountered this? Any advice would be greatly appreciated.

Hi!
I have the same problem that you have. I have tryed the same input in 720p50 with the output program of an Editol V-440HD, this is a HD video mixer that can output in 720p50. With JVC HD-101 or JVC HD-50, always the same “No video”.
But, I have tryed the VTRXchange app from AJA, and what’s my surprise, If I check the 720p50 input option and send a signal from JVC HD101 in 60P mode, I can see the image in the little window overlay. It seems to not switch betwen Hz properly for the input.
If I try to output a signal from FCP in 720p50 via AJA, I can. In monitor show a correct 720p50 signal.
This is maybe a driver issue.
To Kona Support: Maybe if you can check two AJAs KonaLHe, The one that generate Bars in 720p50 sending this to the input of the second AJA Kona LH you can check If in control panel apears as “No Video”.

Finally, an answer form AJA.
It is Final Cut Pro that does not support 720p50. When FCP does, so will Kona.
This is extremely frustrating news. When will apple realise that all of europe and half the rest of the world also produce content professionally. Support is desperately needed ASAP.

Hello, was wondering if you successfully captured 720/25p JVC HDV footage into FCP or not via KONA LHe.
I’m going to attempt to capture with BR HD50E deck next week using component I/O.
Any suggestions will be greatly appreciated. I’m an Aussie user as well. -
negative on the capture using the deck and component at 720p25. The problem here is Final Cut pro, not AJA. It will capture if you set the deck to upconvert to 1080 but the results are less than desirable. The best way I have devised so far is capturing using LumiereHD and upconverting this to 1080p in Final cut pro (actually a 1080i sequence with the field dominance set to none) which will play out of the AJA card properly to a broadcast HD monitor. Very nice results indeed.

Thanks for the tip mykul! So you mean if you convert m2t to DVCPROHD 1080/50i but set field dominance on FCP sequence to none, it becomes 1080/25p?
Or do you set it to none in the conversion process. I’m glad it’s working for you and looking good. Thanks again. -
“So you mean if you convert m2t to DVCPROHD 1080/50i but set field dominance on FCP sequence to none, it becomes 1080/25p?”
No, that will look awful. Simply demultiplex the m2t to a m2v and an aif file using LumiereHD (current beta 1.6b6). (These will be identical to the camera original) Import these two files into final cut. The m2v file will be 720p25. Drop these files into a 1080i50 sequence with the field dominance set to none. Change the aspect ratio in the distort part of the motion tab of the m2v file to -33.3 to correct the pixel aspect (720p is square pixels and 1080i is not!!!) and scale it up to 150%. Now render out to the codec of your choice (uncompressed recomended if you have the hard drive speed and size otherwise DVCPROHD will do). You have now successfully upconverted your 720p25 to 1080p25.
Let me know how you go.

1. KonaLHe doesn’t support 720p50 (only Kona3) – see Aja tech.spec.
2. LumiereHD can’t demultiplex the m2t if source record has time-code breaks – You can use MPEGstreamclip v.1.7 (www.alfanet.it/squared5) for fix Timecode breaks, demultiplex and convert m2t files captured by LumiereHD v.1.6b6 -
Here you can read how to force FCP to edit 720p50:
