its not about the resolution. its about HOW FAST frames can be captured. a video with 640x480 resolution is called DVD quality. but if its recorded in low 15 fps (frames per sec) then its choppy, slow and therefore not TV quality. N95 records DVD quality (sharpness), TV quality (smoothness) video.

DVD resolution is 720×480 or 720×576 (NTSC/PAL,24/30).

@cross
k850 record mp4 video but are you sure the audio codec was mp4 too. I always convert video to 3gp with aac audio codec, it quality much more better than any phone recorded video.
What i want to say, in video, it consist 2 codec, video n audio codec, n till now i never see a phone can record video with mp4/aac audio codec in it, all was amr, even my xphone2 record avi video but the audio codec still amr.
So, any prove the k850 record video mp4 codec format both in video and audio?

since when is QVGA video TV quality? Are you planning on watching it on a 10 inch TV?
its not the 320x240 resolution that makes sakura and sophia's video TV quality. it is the frame rate per seconds that their video can manage to record. 30 fps is standard TV quality.

TV quality would be 25 fps by PAL standard or 23.976/29.97 fps by NTSC standard.
Since 30 fps is higher than any standard's fps a pulldown is required which is much easier than speed-up. |

I have no clue where you are getting your data, however consider the following true data on Wikipedia ....
On 2007-11-16 9:25:00, Wikipedia DVD Article wrote:
DVD-Video is a standard for storing video content on DVD media. In the U.S., weekly DVD-Video rentals first out-numbered weekly VHS cassette rentals in June 2003, illustrating the rapid adoption rate of the technology in the marketplace.[8]
Though many resolutions and formats are supported, most consumer DVD-Video discs use either 4:3 or anamorphic 16:9 aspect ratio MPEG-2 video, stored at a resolution of 720×480 (NTSC) or 720×576 (PAL) at 24, 30, or 60 FPS. Audio is commonly stored using the Dolby Digital (AC-3) or Digital Theater System (DTS) formats, ranging from 16-bits/48kHz to 24-bits/96kHz format with monaural to 7.1 channel "Surround Sound" presentation, and/or MPEG-1 Layer 2. Although the specifications for video and audio requirements vary by global region and television system, many DVD players support all possible formats. DVD-Video also supports features like menus, selectable subtitles, multiple camera angles, and multiple audio tracks.

Resolution
The typical video resolution for an NTSC disc is 720 × 480, while a PAL disc is 720 × 576 (all measured in pixels). For comparison, VHS is roughly equivalent to 320 × 480 (NTSC) or 320 × 576 (PAL/SECAM), while Laserdisc and Super VHS are roughly equivalent to 566 × 480 (NTSC) or 566 × 576 (PAL) edge-to-edge. The specifications for video files on a DVD can be any of the following:
* Up to 9.8 Mbit/s (9800 kbit/s) MPEG-2 video
* Up to 1.856 Mbit/s (1856 kbit/s) MPEG-1 video
* PAL:
720 × 576 pixels MPEG-2 (Called full D1)
704 × 576 pixels MPEG-2
352 × 576 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
352 × 288 pixels MPEG-2
352 × 288 pixels MPEG-1 (Same as the VCD Standard)
* NTSC:
720 × 480 pixels MPEG-2 (Called full D1)
704 × 480 pixels MPEG-2
352 × 480 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
352 × 240 pixels MPEG-2
352 × 240 pixels MPEG-1 (Same as the VCD Standard)

Just putting my 2cents worth, i had a W900 and the video recording was NICE it wasn't the greatest but it was better than the average phone video camera but HONESTLY NOT something i would call "TV QUALITY" it records in 3GP QVGA 30FPS i mean come on now! If you want to talk about good quality then maybe the K850 QVGA 30FPS MPEG-4 is good. But the best has to be the Nokia N93,N93i, N95,N95-8GB, N82 which do it in VGA 30FPS MPEG-4 and probably the LG VIEWTY which does it in a mind blowing VGA 120FPS MPEG-4 now those phones are "TV QUALITY".
and why are you calling the SEs by their codenames?

thecell,
audio codec of sophia's video is AAC
QVGA,
320x240 resolution is indeed NOT TV quality. But the 30 frames per second (FPS) video of sakura and sophia IS TV quality. That is my point.
prom1,

@(K850 owners)
does the framerate dropping in video recordings has been fixed with the new firmware or not???? (recording more than 2-3 mins)
thanks.
(as you may know K850 drops the fps after some seconds of recording) |

simple:
software bug !!!
the K850 recorded video have actualy 30 frames per seconds. BUT after some seconds.. each two frame is recorded twice meaning in reality it shows only 15 frames per second.
but i saw some devices with the new firmware that doesn't have this problem.
W900 uses a hardware accelrator for video encoding so being 2 years senior than K850 is not much of a problem. |
