The GoPro Hero HD has 2.5mm jacks for outputs.

I want to use my small wireless SD video sender. The supplied 3 way RCA cable is too much of a bundle to use well.

So I need a 2.5mm jack to a single RCA or BNC on a short cable using the video segment of the TRS.

I could also use a 2.5mm to 3.5mm adapter as long as it connects the video portion of the TRS as well.

I can't find anything on the net. Lots of Red/White/Yellow 6' cables which I already have and don't want.

Lots of audio connectors for cell phones which I'm not sure will pick off the video portion of a TRS connector.

Ideas?

I also had the same issue and also wanted 90 degree 2.5mm without using and adapter. I had to cut some from other leads and join them into a short (300mm) cable and cover with heat shrink.

2.5mm AV 4 segment 90 degree ---> 3.5mm AV 4 segment 90 degree
