Is there a way to change the "color balance" of the PDR recordings in the car? I'd also bump up the contrast a bit it that is an option. I know such things can be fixed in editors, but would be much nicer if the the out-box files could be corrected.

Where is the PDR camera? Might be able to affix a corrective filter / "gel" in front of it.

Or maybe nobody else sees the green cast....

I agree. The idea is great but the camera is awful. They clam its HD as well but doesnt appear that way. For the price we paid for it GM should replace the camera with a better one.

I was just thinking the same thing. The footage is not great quality..Very cool, but disappointing quality.

Somewhere there was a post addressing this. GM engineer stated camera is 1080 capable but because of data bus limit with all the info they are logging they can't use above 720. Don't recall where I saw this but think it was on CF.

I was told at Rd Atl that the windshield tinting is causing the green glare. Its a special coating for the hud display. Hopefully the aftermarket will kick in and over a better camera maybe even a different mounting position outside the car.

Do all PDR car have HUD? If not, that seems testable.

In either case, I'm positive that the camera hardware can adjusted for White Balance / Color cast, but perhaps they don't expose that in the user interface (understandable), but clearly a "bug" if they didn't calibrate it at the factory for a known green filter (the windshield).

Not a biggie, but just looks like someone applied a "Retro Polaroid" filter to all the video.

Not to get off topic, but we might also start a separate thread of questions to ask GM guys and gals at things like Corvette Corrals, etc., during Q and A sessions.

Back to topic, doing color correction in Microsoft video editor possible?

Im pretty sure all Zo6's have hud. But on the regular C7's most have hud and I doubt GM would have a special windshield for such a small number of cars without hud. Could though. Yea wish GM would do a software update to correct the camera. Maybe we should question tadge on that and see if we can get his response. At least put it in front of him.

Steve Snake Driver

All Z06's do have a HUD. My car is 1LZ and has one.

If it were an HUD windshield film issue wouldn't all cameras have the same problem?

-------------------------

ETA: The idea that it's not 1080 HD doesn't sound right either. Even at 480 SD there's no reason for the color to resolve that way.

The only thing I can think of (by process of elimination) is that it has to do with how the telemetry layer is superimposed on the picture, and that they've done a less than ideal job with the coding and so the telemetry layer is not fully transparent..

The video is recorded at 720p, which is fine. That's what most HDTV channels are. However, the issue is still the camera. Have a look at this post for a comparison oif what 720p can look like with a good camera:

I'm pretty sure there are 2 different windshields for the C7, based on whether or not it has HUD. I know this was the case for the C6. Also, if you look closely at the script on the HUD windshield it has
has HUD in some of the script in the bottom corner. This signals to me that there are other windshields without.

lawdogg149

I agree but now with the Zo6 all having hud and most C7's having hud would be crazy to have such a small number have a different windshield. I dont know this for a fact only using logic.

jsiddall

All Z06s have HUD.

Regardless, the camera looks through the same glass as people do, so if it doesn't look blurry and green/brown from the drivers seat there is no reason the camera has to look that way.

I have noticed a significant difference in a bright sunny day and overcast on the PDR camera. With that all said there is no comparison to any regular camera filming at 720. As stated its not a 720/1080 issue.

This doesn't make sense. Then use a separate bus for the camera, upgrade the processor, etc.

I noticed the quality wasn't good from the prototypes, low res and jerky. When a camera phone can take better video, then there is a problem.

I thought the same thing. Every video I've seen so far has a high green contrast. Is it because of the front windshield tinting. Any way to dial it out after the fact.

lawdogg149

Thats what the GM engineer told me last year at Road Atlanta.

Snorman

You would think they would eliminate the tint in the small area in front of the camera. But that might call for two different windshields to be manufactured (or three? since AFAIK their is a HUD specific one too).

You guys keep going back to the tint but it can't be that ... unless GM went out of their way to find the only camera in the world that interacts with their HUD tint this way. No other camera does this no matter how low the resolution ... I even have additional tint on my windshield and every camera I've used to take pictures or videos has normal picture.

Like I said, the only explanation that makes sense is that it's got to do the way the telemetry is layered on top of the picture, and it has to be that poorly coded layer that produces this effect. imo
