Hi Tom,
The Multibridge does not (currently) provide upconversion. We should soon be releasing the update for down conversion. I don’t think we’ve advertized upconversion but it’s something we would like to do so we’ll probably take a look at it in the New Year.

Hi Mortimer,
Given that Disk Utility did not report any problems, then it is unlikely that directory structure corruption is the cause of your problem. A corrupt directory structure could make it difficult to access files in a particular folder or group of folders but in which case I would expect Disk Utility to detect the problem.
My guess is that you have bad blocks, or some other hardware probelm, with the LaCie drive. It would definitely be worth trying to use the drive with another Mac to see if you can successfully copy the troublesome QuickTime movies to another disk. If so, then try opening them.
If this is not successful, then I recommend you salvage any important files from the drive and then consider reformatting it. If you have a utility that can run a bad block test, then try using it. Under Mac OS 9, there was a free Apple utility named Drive Setup which could perform a bad block test. There are also third party utilities for Mac OS X that run bad block tests although some are more thorough than others. There is a risk of lost data during a bad block test so only conduct it if you have already salvaged whatever data you can.
If bad blocks are found even after the reformat of the drive, then replace the drive as the problem is likely to grow worse. Bad blocks are a fairly common problem and might be covered under a drive warranty.

Hi,
This sounds like some kind of disk issue which is preventing QuickTime from recognizing valid movie content in your captured media. This could be a case of a corrupt directory structure or alternatively a hardware problem.
If you have DiskWarrior, use it to rebuild a new directory structure for your LaCie disk. Then choose to Preview the repairs before you replace the directory structure. This will not modify your disk in any way and you should be able to copy your captured media from the LaCie drive to another location, eg the internal hard disk or another disk array. If you do this and the computer still crashes, then you might be looking at a hardware problem.
If you don’t have DiskWarrior, launch Disk Utility and use it to “Verify Disk” on the LaCie disk. Does it report any errors? If so, quit and get hold of a copy of DiskWarrior 3.0.3. You could attempt to use Disk Utility to repair the damage but the problem sounds serious and once you start a repair with Disk Utility, you can’t easily reverse the process if the repair fails. DiskWarrior enables you to access the disk without modifying it which is great when a disk is on the edge of being salvagable or lost.
If Disk Utility does not report any errors, or if DiskWarrior crashes during the repair, or if DiskWarrior is successful but then the Mac crashes when copying the files, then a hardware problem is likely. We’ll worry about that if it happens but one thing you could try is plugging your LaCie disk in to another Mac and see if you have any more luck copying the file.

Hi Steve,
The PCI Express cable is 2 meters (over 6 feet) when using the Multibridge Extreme in capture mode.
You can use 100 meters (over 300 feet) of SDI cable when using the Multibridge in conjunction with a capture device, such as any DeckLink card, or a deck. This scenario works just like the existing Multibridge HD.

Hi Ed,
I’m glad you figured that out and it is an easy preference to overlook.
Video output can appear rather pink and green if you are working in 4:2:2 mode but the 4:4:4 checkbox is enabled.
Video output can also appear rather pink and green if you are working in 4:4:4 mode but the 4:4:4 checkbox is disabled.
Finally, when using a multiformat monitor with component analog video input, it is necessary to use the monitor’s menu system to switch between:

Hi Peter,
Please review the support note Broadcast monitor goes black during capture. I suspect this will be the answer to your problem and will also let you know which DeckLink output you can use for monitoring.

Hi,
It would be great to know if that makes any difference. In theory what you’ve already tried should work well. However Compressor is more powerful than a simple QuickTime export so hopefully it will help. Please let us know how you go.

Hi George,
We’re waiting on a copy of Aperture to test this problem and we should receive it any day now. In the meanwhile, can you please go in to the DeckLink PrefPane, disable the video desktop and restart your Mac. Now see if Aperture works without crashing. Please let us know as it would be very helpful to know if this works around the problem. Disabling the DeckLink desktop will still enable you to output to a broadcast monitor from Shake and other video applications. I think the crash you are seeing is an OpenGL-related problem introduced in Mac OS X 10.4.3. If my guess is correct, then disabling the DeckLink desktop will work around this issue while it continues to be investigated by Apple and Blackmagic Design.

Hi Michelle,
Further to Kristian’s suggestions, please ensure you have updated to Final Cut Pro HD 5.0.3. It would be worth reviewing the support note No video output from DeckLink in Final Cut Pro HD v5.0 which describes two scenarios which prevent video output from FCP. They are both easy to fix.

Hi Noe,
iDVD is a consumer product and requires a linear video stream. This means that you cannot drop mpeg files in to it. This contrasts to DVD Studio Pro which does allow you to add mpeg files in to a DVD Studio Pro project.
The Help for iDVD recommends exporting movies from the source program in to DV NTSC or DV PAL QuickTime movies.
I haven’t used DVD Studio Pro a lot but I was very impressed by its ability to create High Definition DVD’s using the H.264 codec. It did take a long while but the results were stunning. DVD Studio Pro is definitely capable of producing higher quality DVD’s than iDVD but I’ve also found iDVD to be surprisingly good when in a rush.
