Exploring settings for night use with Ghost HD

[janx101]

Nothing too startling in the vids ... More done so anyone wondering what the other camera modes will do ...

Hope its useful for someone

Nice comparison. I've had my mic level up too high recently and getting some saturation. Haven't tried changing video levels for night riding yet.

Since you have the Ghost, can you upload a very small raw video (less than 10 secs) on a hosting site?
I need the original video from the camera, I want to find out what chipset the camera uses.

The crappy ass JVC camera I have uses Ambarella (opened the camera)
The drift 1080 uses a Zoran Coach 12 (opened the camera)
My samsung camera uses a Zoran Coach 8 (opened the camera)
The LIQ Ego uses Ambarella (found a tag on the video metadata)

The IC that gives the best night quality is the Zoran and is heavily dependent on the firmware.

Thanks Lads! ... Now ... Errr ... Yeah I should be able to organise that ... Being new to this I have seen the RAW footage term ...but ... To check ... Footage that just comes from the camera before running it through or loading it into an editor? ..

I'm using Windows live movie maker (not so high tech) to edit and when I load the vids it takes a short while to 'optimise' the footage during loading ...

Already have a short clip .. But it's been through WMM ... So best just to do any short new clip ... And plug camera in ... Then send it directly to photobucket or similar? ... Then post that link? ... Yeah?

It's not in the meta data, but email drift they will tell you. Very good at answering questions etc.


BTW.

Mic 1
Video 1080 (always)
Exposure -1 for daylight 1 for dusk and night.

That's what I use

Thanks Thunder ..

yeah i plan on doing most stuff in 1080 .. but wanted to test out the various modes and frame rates etc .. mainly so i know what the difference is.... and possibly gain knowledge!! ... it hurted my head a lot!! :lol: ..

also for the general populace to see .. and wonder no more what the low end of the resolution but high frame rates will look like..

all grist for the mill!! :geek:

I don't know about the ghost but on the drift 1080, the higher framerate you can get while keeping a fair image quality is 60 fps @1280x720. 90fps reduces resolution to QVGA (320x240) and the camera interpolates to VGA (or wvga). The resulting footage is blocky and unwatchable.
The drift HD 1080 has a big "resolution lying" problem.
Even after a few bad things, the night recording quality on the 1080 is actually good. Only the gopro hero 2 can compare.

Personally i dont find any footage I take at night usable.

You can get away with some late evening footage.

But the blacks are not black they get that blue distortion in them which really bugs me

I can't believe that the top-of-the-line camera from drift has such a bad quality at night.
Some bits I pasted into a long video for comparison. The camera is a Drift HD 1080.
The source video was not post-processed.

You can see the benefits of riding a bike in the city, not waiting at the back of a long line of cars.
