Long HDMI cable to Intensity Pro and CS4.2 workable?
I’m building a small (10’x10′) webcast studio for a client, feeding Premiere Pro on Windows. I’m planning to use a Panasonic AG HMC40 camera, feeding HDMI over a 30 ft run to a BMD Intensity Pro card in the edit system, capture and edit as HD Motion JPeg 1280×720 on an internal drive.
Most importantly, how is the Intensity card working with CS4.2? I see in the forums that there were delays w/ drivers earlier in the year.
Also, anyone have experience w/ long runs of HDMI? I’ve got a Laird HDMI repeater in the budget–is that needed?
720 Jpeg looks to be about 18 Gigs/hour, or about half again as much as DV. Can I expect one fast internal drive to handle that? Two striped drives?
Lastly, with footage shot in the field, how is CS4 with AVCHD files? Would another camera brand/format be more reliable?Any advice or comments–especially if I’m missing something big, here. I’m cross-posting in the BMD forum. Thanks!

A catagory-2 (hi-speed) HDMI cable is usually good up to about 50′ specially made cables can go upto 100′
I have a intensity pro in one of my computers and have no problems running win7 with CS4 4.2
CS4 works ok with AVCHD but you need a computer with alot of horsepower, and or use a intermediate codec like Cineform Neoscene

How about cable runs up to 150!! With no repeaters or other possible signal corruptwers?
Please go to https://www.bluejeanscables.com and the page that opens should give you baskic info.
I didn’t believe it either, but they are awesom! I am running 75 foot Blue jeans Cable between receiver and projector in my largest home theater – NO issues. Its like the chicken soup – try it, you’ll like it!

75 feet — I’m happy for you. According to the BJC website, the Series 1 cable is certified for “45 feet for Category 1, 25 feet for Category 2” so it may work for my client’s studio. I certainly like the wide range of lengths they carry, and the Tartan series is cheap, too. Thanks.

Thanks, Brian. It looks like it’s a matter of buy some good cable and if it works, don’t buy the repeaters. It’s also good to hear that Intensity’s working well w/ CS4.2.
I like Cineform, but first I’d try transcoding to something already available.
Any cable recommendations? -
Can you use a 1394 cable to OnLocation? It’s designed as a capture application, will do HDV, and has built-in real-time test instrumentation.

I usually buy cables from Newegg, haven’t got a bad one yet, usually read the reviews to find consistenly bad stuff

Thanks for the tip, Brian.
Alan: 1394 max length is officially 15 ft, and I have a 30 ft run here. Add a repeater and the cost is the same as HDMI. Also, others with experience have warned me that long runs of firewire just aren’t that reliable.
With HDMI I should be getting the camera signal without the HDV compression, so a better image for the same price, better results for any greenscreen work, and much cheaper than HDSDI. That’s my thinking, anyway.
Hmm; wonder if OnLocation will work w/ an HDMI card… -
Have not tried OnLocation w/HDMI. I have used longer 1394 cables on occasion, but they have been very thick, heavy ones. They did seem to work, though.
As always, YMMV.

I’m going to throw out two suggestions that I have tested and used in video production: HDMI to CAT6 converter (have tested it to 50 feet of CAT6 cable between boxes) and wireless HDMI units from Gefen. Both offer continuity of the uncompressed signal (out of my Canon HV20’s HDMI port). Capture using the BM Intensity card and converted to a DI file using the Cineform Prospect HD software – all in realtime.
Note that Gefen makes two wireless HDMI models with different technologies. You want the one that offers uncompressed transmission.
Note also that there are many many HDMI to CAT6 converters. There are cheap boxes from Hong Kong, which is what I have and work great to 50 feet (not including the length of the HDMI cables at each end). There are also more expensive units that claim to be good up to hundreds of feet (such as the TVone products).
Cheers
