Git2 poor video quality compared to Git1(original Files)

[Purun]

Hello,

i received today my Git2 cam. I am disappointed with the video and sound quality of the Git2.
In comparison with the Git1 deliver the Git2 in every aspect poorer video quality.
I believe that something is wrong with my sample.

GIT1:
1080P 30FPS
https://dl.dropboxusercontent.com/u/87188249/Git1_2016_0423_174914_003.MOV

GIT2:
Firmware V1.4, 1080P 30FPS, high Bitrate, less sharp
https://dl.dropboxusercontent.com/u/87188249/Git2_2016_0423_174429_013.MP4

GIT2:
Firmware V1.4, 1080P 30FPS, high Bitrate, normal sharp
https://dl.dropboxusercontent.com/u/87188249/Git2_2016_0423_174344_012.MP4

Now with this settings:


Disable Gyro
Normal color
1920 x 1080p
Wide FOV
Normal sharpness
Normal bitrate
Exposure metering "Center"
Use a tripod framing the same scene.

I think your Git2 is on VIVD mode, please try the same test using the same settings on both cams to make a better opinion.

Use this settings:

Disable Gyro
Normal color
1920 x 1080p
Wide FOV
Normal sharpness
Normal bitrate
Exposure metering "Center"
Use a tripod framing the same scene.

And then please post your files.

(I agree, the sound is awful on the Git2)

Saludos.

No, this was standard color mode. Not VIVID.

Yes, FOV is 160° on Git1 vs. 170° on Git2.

I will repeat test tomorrow if the sun is on other site. But, the video quality is still bad.


This both videos from post #1 are with the settings, that you rated to me. Only one difference is higher Bitrate on Git2. I don't think that higher Bitrate will make the video poor.

GIT1:
1080P 30FPS

My opinion is, that the 2MP Sensor(Git1) working better then 16MP Sensor(Git2) if 1080P for you is enough. In the Low-Light Conditions will the difference be much more visible.

 

[Purun]

In my opinion is on the Git2 the standard sharpness already a bit to oversharped. This is the reason why i set it directly after unpacking on sharpness "low". But this deliver me very soft videos without details.
Maybe is my sample just defective.

 

[jokiin]

try it set to normal, this should be without any adjustment

Samples from Today. Comparison 1080p from Git1 vs. 1440p from Git2 vs. 2160p from Git2.

all Settings on standard, no Gyro, no WDR, normal color, normal sharpness.

If you ask me: I don't see any advantage on High-Resolution Samples from the Git2. In comparison 1080P Git1 vs. 1080P Git2 is the video quality on the Git1 still much better. On the Git2 i see always a noise from downsampling. The picture is always a bit to noisy/turbulent. Always less details compare to Git1.

Maybe i like the colors and dynamic range on the Git2 a bit better. But in some situations(Human skin is to red/brown) is the color oversaturated. Here is the Git1 much nicer.

I will sell the Git2 and further use my Git1.

The main advantages of the Git2 vs Git1 when used at HD resolution are 60fps instead of 30fps, gyro image stabilisation and a high resolution sensor thus no false colours from the de-mosaic filter.

Yes, the Git1 sharpening does tend to look better, but you can put the Git2 on soft and then sharpen it on your computer which can do a much better job than either camera because it has far more processing power and as much time as it likes instead of just 1/60th second to do sharpening, gyro stabilisation, writing to memory card etc.

Part of the apparent sharpness of the Git1 is because it is running at sensor resolution and so suffers from false colours from the Bayer de-mosaic filter, but that is not real sharpness and is the reason the colours on the Git2 can look significantly better and more refined.

Also the Git2 needs good lighting to produce really good results, the Git1 will do well in almost any lighting.

They are two very different cameras despite looking identical apart from having "Git2" instead of "Git1" on the front, for some uses the Git1 will be the best and for other uses the Git2 will be best.

Thank you Nigel for your response.

That sounds like a focus issue, where close up items are sharp but things in the distance are not. Might be worth trying to refocus the lens. Thankfully it has HDMI out so you can hook up to a big TV to really get it right.

 

[Gibson99]

I understand your point but I disagree, since all action cams has fixed focus (hyper focal distance). From factory some cameras can come more focused than others but is not the case. What i mean is that when Gyro is on, the image looks like it's being recalculated and it turns a little soft and then it gets sharp again.

I think it could be due to how Gyro works. When i finish my helmet setup i will try again with Gyro OFF.

Bye.

The way the gyro works is it crops a section of the sensor so it does appear to sort of zoom in. Then it moves that crop around inside the physical edges of the image sensor to compensate for motion. Look on YouTube for techmoan's review of the git2 - he has a good visual aid to explain it.

You can have a look at this Gyro comparison video by Bob.

The Git1 is getting a narrower angle of view i don't know why (maybe Git1 FOV specs are different)...i took some screenshots of your samples and i noticed it clearly.

bye.

The FOV is not same for different sensor if using same lens.
