uCorder IRDC250 video camera camcorder example test video

EXPAND FOR MORE INFORMATION
---
This is an example test video of the uCorder IRDC250 video camera camcorder feature. In order to compare and contrast the video and audio capture qualities of this 300k pixel mobile device with others of the same price range, the video capture was taken while holding four different devices at the exact same time, namely (listed in order of quality from best to worst):

MiniDV D005
uCorder IRDC250
LG Neon TE365
INQ Chat 3G

All handy's were set to their highest quality settings for video capture. I have also posted the example test videos of the other three devices right here on YouTube, for you to hold your own comparison and review.

Overall, the MiniDV D005 gave the best video quality and resolution (720X480 @ 31 frames per second) while the INQ Chat 3G gave the worst (with a maximum resolution of 176X144 @ 4.7 FPS). The uCorder IRDC250 produced a 640X480 video file @ 25 FPS, and the LG Neon TE365 produced a 320X240 video file @ 7.6 FPS.

All four devices have included rechargeable lithium-ion batteries, but only the cellular phones (the LG Neon TE365 and the INQ Chat 3G) had LCD displays that allowed the user to view what they were filming at the time.

Sound capture was also best on the MiniDV D005 (PCM S16 LE (araw), Mono, 22050 Hz, 16 bits per sample), sounding most clear and of the highest fidelity (despite a continual knocking sound that can be heard in the background). Sound quality on both the LG Neon TE365 and the INQ Chat 3G (AMR narrow band (samr), Mono, 8000 Hz, 32 bits per sample) were both low and muffled, and on the uCorder IRDC250 (IMA WAV ADPCM Audio (ms), Mono, 8000 Hz, 16 bits per sample), the audio was extremely overmodulated.

For compression and file size sakes, in order of file size, the uCorder IRDC250 produced an AVI video file that for 5:11 of recorded video took up 141,356kb of space, the MiniDV D005 produced an AVI video file that for 1:08 of recorded video took up 60,217kb of space. The LG Neon TE365 produced a 3GP video file that for 4:57 of recorded video took up 14,158kb of space. Finally, the INQ Chat 3G produced a 3GP video file that for 5:51 of recorded video took up 4,391kb of space.
