only two
handsets at this point in time manage to capture TV quality video. 
these are w900 (sakura) and k850 (sophia). does sophia's QVGA video the same with, or better than sakura's?

Sakura has a nVidia GoForce 4800 graphics accelerator as part of its hardware. I'm not sure the K850i has this but the W900i was great at playing back recorded video.

if sophia doesn't have the nVidia graphics accelerator, then sakura's QVGA video is better than sophia?

graphics accelerator in phone is only useful in watching video or video playback..it does not affect video recording
Posted by crossmatched
i haven't compared a sakura and sophia recorded video side by side, but basing on sophia's mp4 format, i guess it has a better video recording capture.
(sakura captures at 3gp format)

i had both phones, k850 is a little better !

W910 captures in QVGA, too, and so does the P990 & P1. W960 will do, too (all are doing it at 15 fps, though).

By TV quality, do you mean VideoCD quality or DVD quality?
Posted by Rifqi_Aziz
Can someone compare these and decide which is better?

although the K850 is stated to record at 30fps... some of them on the market will drop the frame rate to 15 after some seconds of recording.
don't know if this is fixed on the new release.
and K850 video quality is better than W900 (i know that the resolusion is the same) because of the MP4 encoding....and higher bitrate
EDIT:
@rifqi aziz
as i said the K850 is good in the first 10-15 secs then it drops to 15fps.
saw this bug in most of the K850 recordings i seen.
(some of them was virtually 30fps meaning that each two frames was the same..... so what you get? a choppy 15fps!!! but the player still says that it is 30fps)

really? k850 drops the frame rate to 15fps after some time? then sakura is better than sophia in that case. i have tried counting the frames of a sakura recorded video and it is really 30 frames per second.

in what terms is sophia better than sakura? i know in sound recording (of the video) sophia is better because of the mp4 format. but in terms of the "fluidity" or smoothness of the captured video, how does the w900 and k850 fare? what can you say about it?

since when is QVGA video TV quality? Are you planning on watching it on a 10 inch TV?

All JP-8 phones have similar hardwares, and the JP-8 only supports 15FPS QVGA videos, but K850 exceed the limtations, as i always thought, K850 probably had that graphics accelerator inbuilt but SE keeps keeping that a secret
Nvidia GoForce 5100 i think, since the W900's Nvidia 4800 doesn't support up to 5mp resolution of images(only 3mp actually )

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.

AFAIK the standard resolution of TV is 460x480
Posted by crossmatched
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.
Posted by shyam335
DVD resolution is 720×480 or 720×576 (NTSC/PAL,24/30).
Posted by crossmatched
DVD resolution is 720 or 704 or 640 x 480/60 in NTSC and 768 or 720 x 576/50 for PAL or SECAM resolution.

@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?

its not tv quality, whichever you put it. I cant even imagine watching a 320x240 res video on TV.
Posted by LCARS-Expert
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.

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)

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?

120 FPS for QVGA and 30 FPS for VGA
Posted by crossmatched
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,
check out http://en.wikipedia.org/wiki/Video#Video_resolution
Posted by chombos1
@(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)
Posted by crossmatched
how come k850 does frame droppping? w900 which is 2 years senior of k850 doesn't drop frames. isn't k850 supposed to be more technologically advanced than w900?
Posted by chombos1
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.
Posted by kumarracing
Check out my videos on you tube... the one that is taken using W900 is stated on the TAG
The first 3 is taken using W900i while the others are taken using K750i
