Yes, from original videos I've downloaded, K-3 video bitrate is the same as K-30 (21Mbps). But... does K-30 allow you to autofocus again while shooting? If not, K-3 is an advance (even if it's slow to re-autofocus).
Yes, K-30 allow you to re-autofocus while shooting. But you have to know, it's as slow as K-3 while shooting. K-30 is also good in M-Mode like K-3: with Auto-ISO exposure will be fit self-controled, with fixed ISO exposure will be fixed while shooting :-). You can adjust ISO and shutter speed while shooting. Aperture is fixed during shooting in each mode (P, Av, M).

Listen, K-3 has more capabilities in audio and other adjustments.

SO , video quality of K5 (mjpeg with lot of bitrate) is better ok K3 "mov" 21 Mbsec ?!... we must think well before buy a new dlsr and have video more poor of the k5 (that also is not so good)...
I (of course) had the Pana Lumix GH3 in my mind - one year old - that goes up to 72 Mbit
This is very positive because more information prevents compression artefacts ("dirt")
Broadcasters btw. only accept a minimum of 50 Mbit ...

MJPEG may have more of whatever - but it's just a codec with lots of aliasing bad informations.
When I first tried my K-7 I fell of my seat watching the incredible phantasy of green, red, purple
fillings in all contrast-boarders on the sunny buildings and even the landscape, not talking of the
intense coloured noise in most of the darker parts of the picture. This was a complete No-Go-Codec

so..you can think k3 is better for quality (mov at 21mb/s max) about the k7/5 mjpeg ?
I like change body...but I'm afraid...I must put near many money (for me) and IF the quality of the clips are bad of the k7/5..for the codec and crop what hete talking...is a disaster!!! I need more info about, for be sure...

and what when you saw the K5? did it have the same issues to you?

sorry, I can't :-) But i saw some movies made with it. thought it had a nice film render over it. despite the lack of manual controls, because they are getting cheap i still might get one.

The GH3 actually does higher actual res video than the 5DmkIII and D800 because it uses all the sensor's pixel's and downsizes it to 1080p. Other sensors sample every N lines.

21 Mbit/sec wouldn't be that bad if it were IBP frames, but I doubt the K-3 is doing that

my pentax was, k100 , k20, k7, k5 I was very angry about k7 because only 30p and NO MANUAL SETTING---I was belive , K5 was tons better... nothing..THESAME quality of K7 , ok..this time with 25p , BUT...1920 non so incisive, bad dettail like a normal 720P... a big mountani of MOIRE' and agin ..grrrrrrrrr!!!!! NO MANUAL SETTING....little 3 years LATER , her the k3....!!!
ofcourse every body are afraid.... HOW good are the videos quality MORE of the k7/5 (same quality).... ?!? because, is normal to have MORE quality...and this is the BIG question , because..the risiko is , buy and only later undrstand , the quality video of k3 , are thesame or more bad of the k7/5 !!!

I do share most of your anger - but Pentax has been trying hard to make a turn,
but one could doubt they could ever catch up with the other big brands, after all
this time ... while the others have moved further on ...

+ They did understand the importance of good sound on board very well though.
-- They forgot what they can do better in terms of SR
-- Up to now they have not been shure about a "movable monitor" which is a must
on every videocamera. They again didn't catch up with the train leaving the station.

A new firmware might help, or a hack ... but that russian guy never ever cared for
Pentax and Falk Lumo (Forum Member) who had a good tool to soften the negative
results of the mjpg-codec on the K-7 gave up as well ... and I doubt Pentax will give
energy to their few customers who want their K-3 fixed later on - they never did that
intensely before with firmware ...
It's a sad story if you still pray to our fallen god Pentax. RICOH might take over the
power of some sleepers in Pentax burocracy if they could only regain hot numbers,
sales, hopes, and other good news to make sense and fire for further recovery.

I saw some videos the K-3 did now - not bad - but not in any way great or worth
mentioning - they just arrived at the usual middleground - not reaching a GH2 yet.
So I guess you are right - let's wait for a K-1 ... but this would mean that customers
now could be proud of their K-3 to support the energy for RICOH improvements ...

I feel I have to shut up now, just care about something different, to make helpful
believes and positive energy grow higher so they may progress in the future.
Weeping for Pentax won't help much ...

thks, this is helpful. kinda like what i see.
only nbr 6 on your list of initial impressions causes some concern. it is something i noticed on the K01 as well. too much detail can cause the image to breakdown...
I didn't see any disturbing jello. or maybe i missed it..

I'm not a video expert but it appears to me that you are judging the K-7's sensor (noise in the shadows) and its subsampling approach (colour artefacts) rather than the codec.

Apparently the K-5 uses 63.12MBit/s for 1080/25p so maybe it is even the quality of the codec that allowed you to see all those sensor and subsampling artefacts?

Isn't their FluCard solution even better than an articulated monitor?

If streaming to an external monitor (e.g., smartphone or tablet) works well then I'd say that beats an articulated monitor easily.

I think articulated monitors and wifi are solutions to two different (and perhaps overlapping) problems. Articulated monitors are great for the operator, especially when the camera is placed in a difficult space, e.g. against the wall or on the floor. The wi-fi monitor approach is good for other people who want to see the image, but perhaps not as useful for the operator. Unless he uses a wifi device for operating, which sounds like a really bad idea, unless the wifi works perfectly. I wouldn't trust it while operating, though.

Oh, I figured it out. That's my godson...
