Serious Multibridge pro problem
Ok, I am using windows 64bit premiere pro 2.0 with a multibridge.
x2 dual core opterons
tyan thunder k8we motherboard
pny quadro 4500fx graphics card
2 gigs ramI have been having problems with the multibridge. I cannot capture 720 30fps footage from a jvc prohdv br-hd50 deck through the compoment inputs. The footage is pixilated even though i am using the blackmagic uncompressed hd codec. I confirmed this by importing into aftereffects. Image looks bad.
I try hdv capture via firewire using the jvc prohdv settings i downloaded from the adobe site. most of the captures will crash at the end of any kind of capture; batch, in to out, on the fly. The files are not recoverable, etc. I unplug the multibridge. It captures fine for the most part.
Playback. If the multibridge is plugged in, the footage will stutter and flicker. Restarting the program sometimes fixes this. Other times a reboot does the trick.
I call tech support. This is what the guy tells me.
multibridge pro cannot capture component uncompressed 720 24fps, or 30fps for that matter. He gives me a lot of nonsense about how it’s difficult, hard to deal with the time code, then gets into how its not practical to output 24p to monitors cause 24p monitors are so expensive.I say well isn’t it possible to work in 24p and have the hardware downconvert and add pulldown to output to a regular monitor? He says sure. I ask can the multibridge do it? He says no.
Did this guy miss the point completely? Sometimes people bring in 24p stuff and you just need to work on it. If your hardware is bad, its bad.
Is the multibridge that bad?! Am I doing something wrong? Is the tech support guy right about all this? What kind of pro capture device does not support uncompressed 720hd 30p or 24p?
Disturbing.

Hello
Sounds very frustrating but the tech support sounds right. Multibridge does not support these frame rates. This has been a requested feature for some time

Hi,
There are some framerates we do not support but we do look into that as demand grows for it.
Could you tell me how you’re capturing 720p24 from the BR-HD50 via component analog? The deck applies pull down to 720p24 and 720p30 HDV clips on tape on the analog component outputs so you’re getting 720p60 video. 720p24 (or 30) currently exists only in the digital domain which is why you’ll need to use firewire to bring it in.

This can be worked around. I have the same deck as you but work on a Mac. I usually capture 720P30 either converting on the fly via the Multibridge to DVCproHD from the deck’s component analog outputs or import the HDV directly via firewire. The key to conversion reliability seems to be using the RS422 deck control. Either way I can play back a 720p30 timeline using Blackmagic’s 720p59.94 display setting. I have made custom presets to make it easier. I have also had success with 24p but do not use it regularly.

How did you manage the 24p setup?

I have the BRHD50 as well on my mac setup.
right now my workflow for 24p (for 16mm HD aerial telecine I do now and then)
is to capture the 24p from the jvc over firewire with a program called DVHSCAP.I don’t run final cut 5.1.4 so this is the only way I can get 24p hdv.
I batch convert the captured files with mpeg streamclip, to 720 DVCPro-HD files.
