Help! Multibridge Extreme Downconversion not working

[Steven Bradford]

I don’t believe you can do this yet. We’ve been promised this downconversion ability since before we purchased our Multibridge in november 04, and we’re still waiting on it.

Sometimes when you buy a product that seems too good to be true? You discover that it is.

you should use the multibridge application not control panel to setup for converter usage

multibridge application does not work. a box comes up saying to use
the control panel lol.

ok so the stand alone converter does not work yet. Nice. Its a damn good
thing we were able to just downconvert when we digitized it or I’d be in a shit storm with my client.

BlackMagic…..Please DO NOT tell people about available features if they are not available on product release. It makes YOUR customers (us) look bad which makes you look bad.

you have to disconnet the PCIe cable then turn on your mac and connet the USB
just bit tricky

oh, but read the manual – it usually is pretty descriptive 😉

still havent tested the the downconversion my self – been too busy

Hi,

We currently do not support 20p down conversion on the Multibridge Extreme in hardware mode. If you want to do down conversion of a 720p 59.94 clip to NTSC, please use the software down conversion option.

When the Multibridge Extreme is connected to the Mac via the PCIe cable, you change settings in the Blackmagic DeckLink Preferences. If the Multibridge Extreme is not connected to the PCIe card in your G5, it is operating in standalone mode. You’ll need to change the options using the Multibridge Utility and a USB connection to the Multibridge s required.

Do you mean 24P?

Whats the real difference between software and hardware mode?

I successfully captured 720P 59.94 through analog component HD from my JVC -HD100 and captured it in FCP as 10-bit uncompressed SD 16:9 anamorphic with the hardware mode option on.

I wish it would simply have the option to go to tape as well. doesn’t really make sense that it can’t. Is that a future firmware update?

[Borjis] “Whats the real difference between software and hardware mode?”

In software mode, the all outputs of the Multibridge Extreme gets down converted.

In hardware mode, the following configuration is available:

For example, when hardware down conversion is switched on:

Channel A output: HD-SDI
Channel B output: SD-SDI

Component output: HD
Composite Output: – (Composite signal does not have enough bandwidth for HD)

When hardware down conversion is switched on with the “Enable Down Conversion on Analog Output” enabled:

Channel A output: HD-SDI
Channel B output: SD-SDI

Component output: SD
Composite output: SD

At all times, the DVI-D output is in HD.
