OT: HDMI to Composite Convertor

Ken Brits wrote on 4/9/2014, 12:18 PM

Hi I have both a HXR-Sony NX 70 and a Sony HXR-NX 30. Both have only a "Preview Quality" Composite Video out. I video a fair amount of live shows which are projected on to TV's during the show. Up till now, I would normally use my older Sony Vx 2100 for this because the Composite-Out is high quality. Does anyone know of a high quality HDMI to Composite convertor? Many thanks

a cheap quality composite video input to HDMI output is a no brainer anywhere from $40 - $200. However it will at best only deliver the composite video (which is a compromised video signal to begin with) to an HDMI device with some added artifacting. Really not so good as keeping the distribution chain entirely at the composite video to begin with.

Thanks. Sorry, I also forgot to mention that for the on camera, because there is no LANC in on the NX 70 and NX 30, I bought a LANC Adapter. I see loads of cheap convertor units, but is there not a high quality convertor available? The quality out the camera's composite-out is fuzzy and I would like to deliver good quality using the cameras mentioned. Failing that, I have to stay with the VX2100.

as I just stated - you have a composite signal to begin with -then READ that a compromised video signal.

Thanks, I understand what you are saying, but as I said, the composite signal out the NX 30 is not good, whereas the signal out my VX2100 is. I can get a good signal from the HDMI out running through 3 seperate units which delivers a very good image / signal on screen. What I am trying to find out is whether or not there is a good quality single unit, HDMI to Composite which can acheive what I am looking for, going straight from HDMI to Composite. Thanks anyway

We've got at least one converter that'll do HD to SD however the inputs are HD SDI.
I guess you could use a HDMI to HD SDI converter such as the Orchid and feed that to the Redbyte Decimator to do the scaling in only two boxes but that combination is going to cost you over $1,000.

Just realised, it seems Redbyte no longer make the Decimator.

The problem here is HDMI is not used in the broadcast environment. You might to better if you can get a HD component signal out of the camera and feed that into a scaler.

Thanks Bob, I will start looking in that direction

Seems to be a bunch of HDMI to Composite converters available in the $20 to $60 range. I have no experience with any of them, but If I had your need I'd order two or three and see what results I'd get. You might get lucky.

Thanks. I have done a search which has show quite a few. I recently found one here in South Africa in that price range, but the quality was not good. Will keep on trying

Ken check out elec/mann again since the last time we got together they have got some newer HDMI signal converters. I added a bracket with a Velcro strap to my one screen as those HDMI inouts are delicate, i just bust another screen 2 months ago as I was filming on a windy location

Also Sony moved to Digital experience in 4 ways get the DE guys to help you the Sony guy there knows nothing about customer service.
