What determins the quality of an HDMI cable and how good the lenght is?

I want to run a live feed from a Go Pro camera but I heard the quality diminishes the longer you run the cable. What determines how long the cable can be before the signal degrades?

Hut he issue might not be related to the cable but the output power the GoPro output which might decline over longer distances. What distances are you talking about.
There are HDMI transmitter/receivers that might be what you want.
Another option is to get a hdmi 2x1 or similar that have their own DC power to effectively extend/power the HDMI signal for a longer distance..
Presumably you are talking for distances more than the 3 or 6 feet (1 or 2 m)?

I haven't tried anything yet. Just trying to learn the best options.  Are you telling me the quality of the cable is not as important as how much power a camera puts out?
Thanks

Look at hdmi 1.4 support and the throughput/quality.
I.e can handle larger amount of data throughput.
What is the range of distances you are looking at >12 feet?

See whether the camera includes specs for hdmi port distances spec

As far as distance goes remember it's a digital signal so all you need to do is get a series of 1's and 0's safely from one end of the cable to the other.  Analogue cables suffer much more from signal loss over distances.  What sort of distance are you talking about?

There's a lot of hype over cable quality but if they meet the minimum HDMI standard they will easily carry your signal the distance - if you want to wire up the house you can also send HDMI over Cat5 or Cat 6 Ethernet cabling.  

People selling oxygen-free copper, nitrogen gas-injected, gold-plated cables are looking for a market with more money that technical sense!

I want to run between 25-50 feet.  I have seen HDMI cables advertised 100feet but I heard you couldnt run a Go Pro camera that long:

I have SDI cameras that I can run a long ways, if I can run my Go pro cameras 100 feet I would be fine

If you're stuck with that kind of distance consider HDMI over Cat 5 or 6 Ethernet cabling

try gopro with the cables you have. before getting new ones.
hdmi over cat5/6 as mentioned require hdmi/cat-rj45 adapters.
there are also hdmi transmitter/receiver from iogear.

The have 30 ft line of site/wall could add interference.
For example/reference purposes.
