In this site we compare several different video streming services. Main focus will be in live mobile video broadcasting.

January 3, 2010

First test with 4 mobile phones and 1 HD-cam

In this test we shot 4 different concurrent video streams and reference video to the tape. We used following setup:
Network connectionWi-Fi 10M
Video QualityBest
Audio QualityBest
Tested servicesBambuser and Qik
Test devices #1 Nokia N95, Bambuser v. 1.03(6)
#2 Nokia E71, QIK v. 1.0.25
#3 iPhone 3 GS 32G, QIK for 3 GS v. 4.32
#4 iPhone 3 GS 32G, Bambuser v. 1.6.7
Video Time line 00:00:30 Introductions
00:01:00 Services used
00:01:30 Test #1: News paper
00:01:55 Test #2: Nokia monitor test
00:02:15 Test #3: Wide angle test
00:02:45 Test #4: Audio sweep from 10Hz to 200Hz
00:03:35 Test #5: Audio, Music
00:04:20 Test #6: Low light, indoor
00:04:45 Test #7: Low light, outdoor


QIK for 3GS


3 GS

Cam #4 / iPhone 3 GS, 3 mpix camera
Bandwidth used: 298 M (!)

Cam #3 / iPhone 3 GS, 3 mpix camera
Bandwidth used: 54 M


Cam #1 / Nokia N95, 5 mpix camera
Bandwidth used: 53 M

Cam #2 / Nokia E71, 3 mpix camera
Bandwidth used: 76 M

Youtube HQ
Cam #0 / Sony HD video cam + YouTube

First thing you notice is a poor focus in both Nokia videos. Both Nokia devices has a real mechanical focus but it seems that neither Bambuser or QIK can use it. That's why image of both services is far more better when using iPhone.
