slider phone man booo i hate it..
Yep... me too...
Love or hate me...  Nokia 5120 -> Nokia 6120 -> SE T200 -> Motorola V800 -> SE W800 (stay with my wife) - > SE K800 (stay with my mom) -> Nokia N82 Silver -> Nokia N82 Black Edition - Firmware v30.0.019 -> What is the next??. |

I'm yet to see a phone that has decent VGA recording for more than just holding the camera steady and filming. As soon as you introduce a lot of movement, it drops frames or 'shears' like crazy. There's simply not enough processing power, so at best you maintain the 30fps but have horrid artefacts and other nasty side effects.
I'm beginning to wonder what the good of VGA recording is if it goes all patchy as soon as there is any movement.
Honestly, I would rather have crisp clear QVGA rather than stuttery VGA. If they are going to add VGA recording then lets hope its nice and crisp otherwise QVGA would be better IMO.

It must have a VGA @ 30 fps!
Anything less than that is a sin for a 8 mp cameraphone.
dont be happy yet until we see the final product.
some K850's prototypes also had VGA recording ,but the final is QVGA |

t650 protos had vga too......
the main problem for both phones though was................................... battery life!
vga sucked the battery very quickly in them...... maybe why they opted not to use it? though, a bigger battery could have been developed.

I just think we will see later high resolution video recording with new brand , Handy someone ?  ( just a pure guess ) |

anything less than vga recording,would be failure for c905 no matter how good will perform in picture quality... |

@darknoob
I feel that depends heavily on the C905's reception - if there are strong sales (which there should be) - then Sony may be willing enough to give the HandyCam brand to Sony Ericsson...
I feel that Mr Komiyama is taking Sony Ericsson in the right direction, and with his past Sony Corp presence, and experience - it will be him to bring together Sony Ericsson's Global portfolio and identity.
As it stands, I feel we have a very interesting handset in the C905, and I for one am looking forward o upgrading my Orange contract upon it's arrival (here's to hoping though, that Orange get it Generic and FAST - if that means a non retentions deal - and a deal instore, then so be it!!!)
The C905 is already a winner with it's slick design - I hope it's a winner in the performance side of things...

Hiron says:
Drops frames or crazy artifacts is usually because of poor video compression algorithm, not the phone lags. The compression usually works by merging the same images information in the several frames, and of course it works best if there are no movement (steady images, little information has changed.)
A movement of the video could lead to many image information captured (the images changes rapidly.)
If you shrink this huge amount of information into the constant bitrate (usually low bitrate,) the compression will make the video looks awkwardly, simply because there is not enough space to store the information.
The makes it easy. Took any Hi-Quality MPEG Video. Convert it to:
1. 96kbps CBR, 30fps 3GP
2. 512kbps CBR, 30fps 3GP
Voila! You've got the same effects (drops frames or crazy artifacts especially when there are some movements) on the 96-kbps 3GP.
Although there are some quality loss on the 512kbps 3GP (compared to MPEG), you would realize that a drops frames or crazy artifacts problems is gone when there is some rapid movement.
I think that's not because a phone lag. If Yes, even without movement you will get the same drops frames or crazy artifacts.
But the problems persist when there are some movements, right? So that's because a video bitrate itself. Increasing the bitrates (of course increasing a file size) would resolve this problem.
And if you want to see the original .MP4 video produced by C905 (VGA@30fps) just download it (9 MB): http://blip.tv/file/get/Technogadget-VideoTestC905Shino245.mp4
I see that eltoffer has posted the .flv links. But since the .flv has been ripped from .mp4 itself (and it means quality loss,) I recommend to try the .MP4. Fresh from the oven 
Strange information I get from this .MP4 (assuming this is genuine recording by C905):
3000kbps video bitrate, recorded @25FPS??? It's not 30fps.
3000kbps is a normal video bitrate for VGA .MP4
The video compression algorithm is conventional MPEG, and I would recommend .H264 algorithm for better results.
The sound is AAC 96kbps 48kHz, stereo. SE added a dual microphone in C902 and C905 to give a stereo effect in video recording. Just see the whitepapers.
I wish we could customize a video resolution and bitrate in C905 menu. . . You have see it, 9 MB++ in only 27 seconds video. QVGA would makes only 2 MB++
And like the others said, this is just one of C905 prototype that has VGA recording, I hope they implement this in final version.
But at least right now, the whitepapers says it: QVGA@30fps.
Just to remind you about an interview in June announcement:
Interviewers: "When will SE break the ice, and will release a phone that will record in VGA?"
SonyEricsson: "SE is not developing one, and will not develop one in the near future, because the Cyber-Shot range is dedicated for still photos, not videos"
Makes me almost spill my milk to the keyboard when I saw this funny statement. I think all of you know that Bravia-LCD, CyberShot, and VGA@30fps already merged in one handset like SO905iCS. What's the point of saying such this fools answers? "Not developing one?"
And I have heard something like HandyCam-Branded Handset??? That's not a smart steps. SE already had Walkman and Cybershot, and they seems can't handle it very much. You can't promise extreme video capabilities into a little-dimension gadget.
More Branding expansion means spreaded developing concentration, higher costs and of course customers confusion. . . Not efficient and fools management decision I think. . .
As the same camera-wise, I thought Image and Video Recording capabilities is better added in same handsets. That would increase the sell points, instead of dividing it into two handsets that could lead to costumer confusion and insatisfaction. . .
Why not just make something like all-in-one handsets??? They've done it a little in K850i by adding Walkman 3.0 and MegaBass.
Wonder if SE could add Crystalizer, Freeverb and 12-Band Equalizer, or 24-bit 192kHz hardware output in their Walkman Lines 
And although if they still released HandyCam-branded, they still can makes a huge different from CyberShot, something like this:
1. CyberShot: 640x480 (VGA) @ 30fps, MP4
2. HandyCam: 720x480 @ 60fps, H264 yuv Encoding, or maybe 1920x1080 @ 100fps FULL HD RAW Video, or DivX
See the point? No reason they don't put VGA on C905. . . If they can make a huge difference of video recording capability like I mentioned, I would agree with their decision of releasing HandyCam handsets.
But if the HandyCam handsets doesn't have breathtaking and breakthrough capabilities, the HandyCam branding would be a crap branding. I didn't think Sony will give their HandyCam brands to SonyEricsson easily.
Just see at the PSP branding, Sony simply doesn't give it in because SE doesn't has a decent hardware platform with dedicated 3D chipsets. All they can do until now is using ARM9 Outdated Architecture. . .
But I still doesn't agree of their decision by putting QVGA to C905.
Thanks for your attention,
Hiron

@Hiron Tx for bothering to tippe such a long post  I am into video rec/edit.Have you checked a N95 (latest firmware) video,resampled to 25 fps and soothed + slightly sharpened (all done with virtualdub)? Now,it may not be dvd quality,but is not far behind either Do you think the C905 will record anywhere close to that? What we NEED now in a cellphone is AUTOFOCUS while video recording ! It will help a lot with closeups !

A100 has Autofocus and macro in video recording, but it's disappear in A200.. |

Honestly speaking..i really don't care if this phone only does QVGA. I mean..really, how frequent you use a phone as a camcorder? the focus is in still photos. and i'm not surprise that even SE people has that kind of thinking. |

to go further....
the focusing mechanism must work even DURING the recording.... auto adjusting the focus when the subject distance is changed... |
