Wireless video transmitter.. Glide Cam to director

Hi,

I'm looking in the world of wireless video transmitters small enough to strap on to the lower counterbalance of the glide cam.

I have found this http://www.vfmstore.com/tr100412.htm the transmitter is small 60x35x63 and runs of 12v. with a range up to 1000 feet (300 meters)

What do guys think?

Do you know something more appropriate?
 
The stuff I'v used before was the 2.4 Ghz , The 1 watt TX output is a must.
Now you will get 300m line of sight on a good day with the gods on your side but for reliable reception perhaps 30m is more accurate.
You will get the occasional glitch or spike but generally the picture is pretty reasonable for framing or to give an idea of how the shot is progressing. But forget trying to monitor colours etc using this in the transmission chain
 
If you just want to check framing, then it will work just fine and it isn't too expensive at $200.Which model Glidecam are you using?
 
Check "video range" or dpcav. You can find SD AV wireless for half the price. There are also ebay sellers for china that sell receiver transmitter pairs for $40-70 (eg. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120494291268 ) . They work OK, not perfect but should be good enough for frame monitoring. It is the same technology as the stuff in your link, so it is unlikely that there is much extra quality for the more expensive SD AV units. (just avoid the super small super cheap ebay transmiters as they are flimsy.)

Thanx,
Now I bought a 2w sender receiver for 61 usd and free shipping :)
 
Robert Benson makes great wireless framing monitor systems for remarkably little money. Certainly not an on camera monitor but great for framing. SD starts under $300, HDMI around $600. Includes everything - monitor, transmitter, receiver and batteries. I use mine when the camera is on a crane or steadicam. Amazing value for the money. No connection, just a satisfied customer.

Just as an alternative option, i use a 10 meter HDMI cable whenever I either have the camera on a jib or have somebody else on camera duties. Works a treat, although i imagine that having a cable trailing around isn't ideal for everyone. I just make sure that I manage my cables well & let everyone know to keep clear of it.

Using a Steadicam rig with a trailing cable, while a thought is not something that is actually practical or advised.The cable will cause the stabilizer to be constantly pulling, exactly the reason that wireless units are needed. On a jib, it's an entirely different situation, the same as HH cabled, not a problem.

how do you run the ebay ones off a battery?

Au contraire! I've actually done this successfully with my stabiliser rig a few times when i used to run a Firewire cable from my HVX, by taping the cable to one of the shoulder straps of the vest, so even if it does pull, it pulls on that and not the camera/gimble. I just make sure there's just the right amount of slack between where it's taped on the shoulder & where it goes into the camera.

I just used to run along with my laptop/monitor behind my camera operator, which is something i'll soon be putting into practice with my AF101 & my 7-inch LCD. But like i said, i'd understand why other wouldn't be keen on this approach, but for me i actually prefer moving along just behind the camera & getting up close, which is useful when giving direction between takes instead of shouting or using a megaphone from 30meters away.

But i also understand that monitoring the footage isn't just for the benefit of the director & that there may be others that wish to see the action toos, so a wireless solution may be better if that's the case.
 
Yeah, I've run tethered on my Steadicam a number of times. Prefer not to, of course, but you do whatchu gotta do. The trick, besides firmly attaching the cable to the back of your vest, is to run it (barrelled, into a thin cable) from there to a loop off your gimbal hand (being a righty, that's my left), making the loop about a foot or so of slack. Then it runs to the sled connection. And attached at sled level, not up high somewhere on the camera.

The loop adds a level of "disconnect" to the cable, helping the rig fly freely.
