Default Low light video comparison: Sony Hx9v, Kodak Zi8, Sony 3D Bloggie, Samsung W200

The Samsung W200 seems to have the best resolution and color of all of the tiny video cameras. Picked as best under $250 by camcorderinfo. It's also waterproof and dustproof.

Here are frame grabs from the video:

Sony Hx9v, Kodak Zi8, then Sony 3D Bloggie, Then Samsung W200

Was this not the Model for around $100.00 today at your local bestbuy?

Yes, it is/was $100 at Bestbuy and Sears (reduced temporarily from $160).

Default takes good photos too (5.5MP)

Here's a still photo from the camera:

Default Samsung W200 video

This video puts this inexpensive, tiny video camera through a gauntlet of challenges: bright light, dim light in NYC subway station and train and GCT, dim light in store and restaurant, night shots. Amazing color, dynamic range and sharpness under very different and difficult lighting conditions.

And it's waterproof, dustproof and shockproof.

You can download the original file, and avoid Vimeo compression.

Here's another W200 HD video, which is more fun: food purveying, Christmas tree trimming, cider, leaf blowing, Ghandhi, painting, knick-knacks, yoga, music.

Very impressive footage.

Thank you so much for posting it.

PS - I ran BitRate Viewer on your two downloaded Vimeo files
it appears if the Samsung HMX-W200 is very efficient on its storage -
at approx 2.498Mb/s average.

Would you mind running BitRate Viewer please on some original/unedited footage using the same 720p/30fps?

Thanks,

Default Indoor NYC Christmas Video

Music - classical, rock, Chinese -, lights, toy trains, and Santa! All inside and underground.

Yes, the W200 is very efficient because it makes good use of variable bit rate. For this 108030p video, the average bitrate is 17.9 Mbps, but it has a peak of 34.1 Mbps and a low of 7.1 Mbps.

Thanks for that -
for 1080p/30fps those figures do not look that efficient.

The Kodak Zi8 (which you have) also uses vbr, is only 37% the bit rate/size -
Kodak Zi8 @1080p 30fps

average bit rate over a 1.775GB file (37min) = 6,676 kbps
= 6.676Mbps

Even the Kodak Zx3 - which is less efficient using CBR (Constant Bit Rate)
is 67% the bit rate/size -

Kodak Zx3 @ 1080p 30fps

over a 873MB file (10+mins) average bit rate = 12,017kps
= 12.017Mbps

Both these Kodaks at 720p 30fps

Kodak Zi8 @ 720p 30fps

over a 2.005GB file (1hr 34min) average bit rate = 2,913kbps
= 2.913Mbps

Zx3 @ 720p 30fps

over a 3.665GB file (1hr 04min) average bit rate = 7,997kps
=7.997Mbps

This is the reason I asked for BitRate Viewer reading on an original unedited footage at 720p 30fps
- because those readings from the files I downloaded from Vimeo looked very low @ ~ 2.5Mbps average......

Thanks

EDIT to ADD -
re: you latest video on Vimeo:
http://vimeo.com/33095758

Good sense of composition/framing and sequencing -
and very impressive quality for the conditions.

However I only just noticed that video as linked is only 720p/30fps
as opposed to what you said 1080p/30fps.

The average bitrate for that downloaded 720p/30fps video as displayed with MediaInfo Lite was 2.516Mbps.

Default efficient does not mean low *average* bitrate

"However I only just noticed that video as linked is only 720p/30fps
as opposed to what you said 1080p/30fps."

I think what you are saying is confusing efficiency and quality, although perhaps I do not understand what you are saying.

1. The share button on Youtube is for 720p. You go to the Youtube link and change the resolution to 1080p. Youtube converts the video. The bitrate Youtube uses is less than that used by the camcorder. And the quality is much less than the original.

2. You do not seem to understand what I am calling efficient. The vbr changes the bitrate a lot depending on the amount of information needed in the shot. Efficiency is measured by the variance (second moment), not the mean (first moment of the distribition of bitrates). The average bitrate tells us about the quality overall for an identical codec.

The W200 has an average bitrate that is much higher than the other cameras. That means it has higher quality (everything else the same). It is not "efficient" to have a lower average bitrate, *given all the cameras you are comparing use the same codec*; it's just lower quality. The codec deterimines the efficiency, and, again, that is the same on all the camcorders (AVC. h264). That the average bitrate is higher for mjpeg than for avc is becasue the avc codec is more efficient. But for the same codec, higher bitrate means higher potential quality.

I love this little program.
