Troubleshooting: No OSD and Poor Image Quality on FPV Camera
Ok so still no OSD, i did not notice first time that the image is almost analog... very low quality. Even if the set up is perfectly done... AND no OSD... AND nothing was recorded on the SD card either @*!&@*! damn it.. is this camera broken? If I follow the advice below about the red message here i should swap the camera with another one I have... grrr

you camera is obviously not broken.
you have a betaflght setting issue or incorrect waring to your VTX
the way HD digital dose the OSD is the FC talks to the VTX and then the VTX draws the OSD your FC and VTX are not talking to each other
the common wiring mistake is the TX and RX wires are crossed, to should be TX -> RX and RX->TX. if your using the plugs you still need to double check it not every FC manufacture orders the pins the same way. DJI plugs have 6 wires if your are not using a DJI controller you can exclude the SBUS and the closest ground wire to the SBUS.
in betafligh you need to configure betafligt to use digital OSD its not setup that way buy default the easiest way is to use a preset JB talks about in this video
if you dont want to use a preset or its not available yet you need to use a few lines in the CLI instruction on what to type in are in the VTX manual sec 4.6 (page 18 and 19)

Hold on — thanks, but all of this sounds plausible. Still, I'd like to know one thing first: is all of this caused by the wires to the DJI module being soldered the wrong way around? I mean the missing OSD — and again, it looks correctly configured in Betaflight; I have other drones and I can bring up the OSD however I want, but not on this one. So do I need to physically swap the wires, or can it be fixed in software? If I fix that, will the OSD show up, will the camera resolution be HD, and will it record to the SD card? Do you think all three problems are caused by the wires or I can solve it within betaflight?

If this is for the toothpick build, can you post a pic of the drone opened up and betaflight ports tab? I watched the original video again and there were some things sticking out I couldn't tell what they were for. I think seeing the wiring and how the beta flight ports are set up will tell which direction to go. I still cant tell if this is 100% soft/firmware or hardware or both.

i would first do a visual inspection of the wires, before swapping wires
look the O4 plug and the FC socket your going to have to goggle the wiring guide for your FC. look at the colors of wires and make sure they go to the correct place, most follow the DJI pin order on the 6pin plug but not all of them do. A UART (Universal Asynchronous Receiver-Transmitter) uses 2 wires for data transmission one pin/pad will be TX and this one only talks, the other RX only listen so the TX need to be wired to a RX is part is quite opposite to all the other pads on a FC. if these wires are crossed your FC can not talk to your VTX and you will not get a OSD.
i dont not know what exactly is wrong with your drone i need more info i would need it in fount of me
i do know the 2 most common cause of no OSD is incorrect wiring and betalight settings

The reason that the video quality is not so good - make sure that the player is set at 1080p or higher when you are watching. Right now the player that I'm watching is set at 360p, as soon as I set it at 1080p the picture is clear as a bell! 😁
