FireWire hub

Martin Pauly · October 26th, 2006, 12:00 PM

I tried to get a feel for whether FireWire hubs are a good idea for video editing or not. I got very mixed results from a search, but mostly in fairly old posts, so I am hoping for some feedback from more recent experience that you guys may have made.

My equipment includes an early 20" Intel iMac with two FireWire-400 ports, a Sony HDV camera, two FireWire harddrives, and a Tascam firewire mixer. To that, I will likely add another FireWire audio device for more audio outputs in the not too distant future.

Right now, I always have the two external harddrives connected (the first one to the iMac, the second one to the other port of the first). The iMac's second port I use either for the mixer of the camera, depending on what I need at the time.

To extend this setup (or make it more convenient), I can think of either chaining devices more (such as adding the mixer to the harddrive chain), or using a FireWire hub. I don't know much about this topic, but I expect that either approach may have some difficulties or things to consider.

Any advise would be appreciated!

Devices like video capturing, sound capturing, control surfaces, etc. will play up as soon as you put a firewire hub in line. I think a lot comes down to the individual device. Some will function fine on an externally powered hub, others will not. Check the documentation of the specific devices. I currently have four Lacie Firewire 400 Hard Drives daisy chained, with no issues so far. So maybe keep your hard drives on one firewire bus/point, and your audio gear on another. You could try putting a hub AFTER any gear that is incompadible with a hub.

Same with USB. Some devices work fine via a hub - others will not. For example, my ProTools M-Box will not work properly when you put it via a HUB.

As you can't add any more Firewire ports on your iMac, I guess you'll just have to play around until you can get all your devices working...

Hope this helps...

Oh, and I ALWAYS keep my camera/deck on a SEPERATE firewire port for capturing.

Maybe a Firewire Switch (ie. so you can route specific firewire devices to you machine when you need them) is worth looking into?
