HDMI signal from the air to the ground

Anyone knows of a device that can send an HDMI signal to the ground. Most up to date DSLR cameras now have a HDMI output and not an AV output anymore. One can use a converter to change the HDMI to AV but that adds another 220 grams of weight and the AV signal is not very good.

Hi Haidar

There is a lot of guys throwing in their penny's worth but it is expected in a forum. So far I have found it a most interesting discussion, I think everyone can learn from it, even the novices like myself but you are absolutely right, no one has really come up with a solid answer. Maybe the future is not yet upon us......

some things are possible and some are not....your client(or director) will have to be satisfyed with not so good picture in live transmission and after you land(that will be max 15min flight anway) you will show him something better...HDMI is not a must ,go pro with sunex will be ok for preview as second camera....or something like this guy did... http://www.rcgroups.com/forums/showthread.php?t=1519474&page=15

Let me explain, you will be very lucky to get more than 4 to 6 minutes in the air with what we are talking about (Octocopter with Red Scarlet or Sony FS100). When one edits a film a 4 to 20 second shot is more than enough. But that is besides the point, the point is to see a very clear picture on the ground while the aircraft is in the air. Because the flight time is so short you need to take a good shot.

This is a steep learning curve for all of us.

May I make a suggestion so it helps everyone. If you are a novice on the specific subject give yourself a rating of 1 out of 10. If ten (10) you think you know a lot about the subject and if one (1) you know very little. Nothing to be shy about.

Then if you have found a product that works for you and you think it is the best on the market give it another rating out of ten (ten the highest and one the lowest), slowly but surely as a forum with a common interest we shall find the best solution for all of us.

This is what a forum is all about to help each other and find the less expensive way.

Thanks for the links, the Q4 really looks awesome!

Yes it is the Red camera and the Droidworx Sjyjib 8 as according to your links, however if you buy it from Droidworx you will pay much less than the Euro price quote by Kopterworks. In the film industry you will not buy the Red raher rent it, if its required by client.

The Teradek seems to be the top end answer, however in my country with the very very expensive cost of streaming video through a cellular network it will not be a viable way to go. What a pity! Maybe when we gat a faster bandwidth and cheaper rates it will be the way to go.

Anyone out there with a rating for Infrontech products???

@Gerry, Droidworx don't sell to the public.  They are wholesale only, and their price excludes, tax, shipping and customs duty.  The recommended retail price for Droidworx retailers is the price listed on the Droidworx site plus 8%.  That being said the Droidworx price is 1875 Euros = $2 334 AUD.  

This is about $200 AUD more than the RRP set by Droidworx.

If you want a Skyjib frame, send me a message.  I can get you one cheaper.

Thanks for the You Tube video of the Teradeck it explains everything, which is difficult explain in words. So, we don't have to explain how it works.

I use the Sony Alpha 77a camera.
