Enligt några hackers har man tydligen "lyckas"

Philip bloom skriver på sin blogg om detta

 

http://philipbloom.net/2010/12/30/shoot-2k-3k-and-4k-on-the-canon-550d-t2i-coming-in-2-weeks/

 

 

Dessa funktioner ska tydligen fungera enligt hackerna själva och ja, uppdateringen släpps den 1e januari 2011!

 

will be released on January 1st 2011 11:11pm EST

will be free

4K resolution will be 4096×2304

60p in 1080p mode possible

Moire and aliasing “fixed”

5D Mark II support will be released on January 11, 2011

Recording time in 4K is only 6 seconds. Maybe 10 seconds in future release

Writing 6 Seconds of 4K footage to card takes about 30 seconds.

25p is NOT going to happen. Probably never.

Heating was a problem until 6 days ago. But not anymore.

Has built in limiter so you won’t brick your camera

Battery will be sucked up pretty fast.

Will NOT record in 16:9 (coming in future release)

Will be frist released for T2i (550D) and will later come to 7D, 5D Mark II. No Word on 60D yet.

Monthly updated planned on each months 1st

First 2 releases will be free. Later releases won’t. Will be around 50 USD

“Rolling Shutter isn’t much of an issue”

No drop frames

Youtube User Dod3032 will get the firmare one day early and will put up videos on youtube on 2011-01-01

Sourcecode will also be released

LiveView won’t work while recording

HDMI Out will still work

1080p with 175Mb/s Bitrate looks georgeus

Works only with fast Class10 cards

Working cards are: Sandisk Extreme III class 10 8gb and above. Transcend class 10 16gb and above and Lexar Pro class 10 32gb.

Color-Space 4:2:2

No playback in-camera

7D Security is a pain in butt because of firmware counter. So no support yet.

Not T1i (they don’t have one)

Development took about 2 months in total

Special Website will be up soon

There was talk of it future version costing $50, that simply can’t happen as the firmware is Canon copyright and if it is distributed modified for financial gain there will be a fair bit of trouble!!

Men som sagt, vi får ju se ifall det är en hoax eller inte, få vet om detta är genuint eller ej och om det inte är det, gissa vem som kommer köpa en 550D. ;)

Man kanske borde blivit fundersam på 175Mb/s, vilket skulle kräva en skrivhastighet på 21MB/s. Standard videoströmmen är på runt 4-5MB/s.

Om det skulle ta 30s att spara 6s 4k skulle det innebära att bufferten skulle vara minst 24s [30-6s]x21MB/s=504MB. Vet inte riktigt hur stor den är, men skulle gissa på max128MB (6-7 rawbilder har jag för mig den klarar).
