Does anybody know why outside is so over exposed? im using a GoPro HD2.

I was thinking maybe theres too much black in the picture from the cabin for it. But i have know idea when it comes to filming...

Check to see if your metering on the GoPro is set to "Spot Metering," which is the small dot in the middle of a square. That way, it takes a light reading from just the centre of the image instead of the whole screen (Evaluative Metering). That might help, bet even then with a GoPro it can be hit and miss unless you have the LCD Backpak or can aim it almost spot-on out the windscreen.

It's trying to balance for the majority of the screen. Since most of your video is of the inside of the car it has gone for that. You can try repositioning it to see more out the window next time.

I don't know what settings they have, but you might also be able to make it work on the focal point, then all you need to do is get the outside of the car in the center of the screen for more magic. Either way, its 1 or the other really, if you get good outside, inside will be dark.

Looks awesome fun either way!!

+1 the orginal GoPro HD's came default average metering. I had to turn spot metering on. The down side is that the cabin will be much darker. But when shooting in a dark environment with bright outside you have to "tell" the device what you want to do. The "Dot" that Nick said is pretty much in the centre of the picture that is used to read how much light and therefore what exposure setting to use. When you aim it just be sure the centre of the frame goes out the windscreen.

If you have editing software you can usually bring down the exposure a bit as long as there's still a bit of detail (not washed out or all white). The colors and contrast won't be as good but will give a bit more detail.

Ok, cheers for the info guys. I'll gives that a try

What do you recommend for editing and uploading to youtube with Eric? I used the window's program but it came out pixelated in places and was quite a large file too I think (380m)

When editing I assume you mean just clipping - right? Streamclip (freebie) can do that and maintain the H.264 Mpeg4 codec the GoPro uses. It's only basic but will do clipping. Be sure to stay on an MPEG4 code - H.264 is best right now, or else xvid or divx. H.264 will produce the best looking video with the smallest size but may take longer to encode.

The GoPro in 50/60 frames progressive is ahead of the standards right now. There isn't really an Official standard that does that framerate in HD. Hence why I recommend streamclip if you just want to clip them down.

For full on video editing I use Corel VideoStudio Pro X. Does everything I need and more and only $120 on line.

For YouTube and Vimeo I usually create a 720P file in DivX format with a reasonable bitrate. Still a couple hundred megs for a few minutes but looks so much better now that everyone has big monitors and broadband.

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
