Hey all, I love my Eyesy but can’t get it to play nicely with my Panasonic WJ-MX50A video mixer. The RCA output is in vibrant color when plugged directly into a CRT, but loses the chroma signal when routed through the mixer. Other color video sources routed through the mixer work just fine. Is this a setting on the Eyesy? Do I need a converter? I have no idea why my Eyesy doesn’t come through in all its colorful glory. Any and all leads welcome!
The WJ-MX50A has many composite inputs, right? Do you get the same monochrome image from all the inputs?
Yes, the image is monochrome across all inputs. All inputs are in color with other sources, just not the Eyesy.
(Actually, I had this same problem with the ETC as well, but I had attributed that to my HDMI-to-composite converter.)
Is the mixer expecting an interlaced NTSC signal?
The composite signal is generated by the rPi and there aren’t many settings available to change - you can see what is available in the sdtv_mode section: Video options in config.txt - Raspberry Pi Documentation
Can you try running the EYESY’s composite signal into and then out of another device like a VCR? It might make enough of a difference.
Great idea, but still no dice. Routed through the VCR the Eyesy still shows in B&W.
Looking into the config.txt link you sent, maybe there’s some insight there.
Did you ever have any luck with this? I get the same issue with MX50, AVE5 and the Edirol V4. Which makes EYESY almost totally useless in my rig. I was so looking forward to getting it, but it’s not worth having if it won’t work with other gear… Anyone know what the problem is? Or rather, anyone SOLVED the problem?
I have an Edirol V4 and my EYESY works fine with it. If there’s any information I could give that would help let me know.

Hey i have the same problem with eyesy and Edirol V4. Did you find any solution?
I just had my EYESY directly going into the V4 composite input with a regular RCA cable and the V4 directly into the TV. It was working fine out the box. I didn’t have to mess with any settings in configs or anything to get the color working.

Just bought one of the newest batch, and seeing the same problem, good image from the Eyesy over composite when direct into a TV, monochrome and glitchy when through two different Panasonic mixers. an MX-10 and a WJ-AVE55.
Everything is PAL, no problems from the mixer with any other composite-out devices that I can find.
However Ive done some testing with two Pi3 boards, one running MP4Museum v6, the other running R_E_C_U_R, and the same thing happens. So I guess its intrinsic to the RPi composite out.
Cheap and cheerful solution that works straight away is just fire HDMI through a £6 HDMI2AV box from Amazon, though I may look into a couple of other options.
A bit annoying, though, in that I got the Panasonics because they were supposed to not lose sync with odd and/or glitchy video signals.
Forgive this post from someone who neither owns an EYESY nor understands anything about video, but… Out of curiosity I did a quick Google search on “Panasonic video mixer raspberry pi problem” and found this discussion amongst others. There are some suggested explanations and solutions there, but mainly it seems it is a problem not limited to the EYESY and shared by others.
Yes, there’s clearly something about the way a whole bunch of Panasonics mixers are handling composite video that doesnt work properly with input from certain devices. Seems likely that this relates to something not in the expected tolerances within that composite signal, possibly sync.
And it definitely seems that the Pi3 family (including the Pi3 compute Module that the Eyesy is based on, but the regular Pi3 as well) are amongst those dont deliver a composite signal that the Panasonics like. Ive now tested the Eyesy through a couple of other analog composite devices, like a Camlink VMX5000 ‘enhancer’ but they’re not cleaning up whatever it is that’s not playing well with the Panasonic.
In the longer term, I might investigate the ‘Sync-Ope’ board (Sync-ope : sync restoring circuit - next revision ideas - current projects - scanlines) but since the cheapest HDMI to composite adaptors out there work perfectly, that’s probably what I’ll stick with in the meantime. ( I just ordered some boards from the guy in Australia who does the Sync-Ope, but that wasnt one of them, sadly…)
Feels like the whole thing is kind of ironic because the Panasonics are (well, were) cheap options for Time Base Correction circuitry that works well with signals with poor sync. (see Reddit - Dive into anything for example)
