I think you'll find that Mode functions are listed as features, not as a specification.

I'm certainly not a videographer but my daughter is a broadcast TV News Producer. This certainly isn't a perfect example, but she claims her shooters manual focus because they have better control that way.

Just sayin'.

Yup, when you have the luxury of sending out a cameraman, a reporter, and an assistant out to a shot, then it makes sense to manual focus.

I'm more often than not a one man crew, setting up the camera, lights, audio, and then conducting the interview. In those situations I'll take all the electronic aids that I can get.

It's funny, after shooting some video myself, I totally appreciate the long list of credits at the end of a movie now!

I've been reading some good things about video from the D7100, the K-3's natural competitor, including good dynamic range and uncompressed video output from the HDMI port, some even rating it as good as the Canon 5D3. Lets hope the K-3 is as good; uncompressed HDMI would be sweet.

I have downloaded it with maximum quality several hours ago. The video was deleted! Does it mean final firmware will give significantly better video and Ricoh forced to remove the video?

Probably was fake.

You would be surprised how often even a broadcast Network Evening News segment is done with local talent and one universal camera/audio/light technician - and the "Producer" is the assistant.

I don't really get this video. Does not show anything for me...thechnical wise. Maybe, maybe DR? Have to wait proper ones.

Danas_Anis · 10-14-2013, 10:52 AM

so is there anyone with the pre-production or whatever version of the K-3 and could tell us what is the video bit rate? This mystery is just killing, does the Professional H.264 video mean that Pentax Ricoh gave it better technical specification? Higher bit rate, better compression method, improved the DR?

Hopefully one day it will be a regular practice for manufacturers to mention video bit rates in specifications as they do for still images.

I am so curious about the more in detail video specifications of k-3.

I think the lack of this information is indicative of where Pentax is targeting the K-3. If they were really targeting the serious pro-am market, I'd imagine that they'd have this information readily available. That's, for example, what Panasonic does with the GH cameras.

So until someone gets their hands on one and starts putting it through its paces, I'm assuming that the video features will be a step forward for Pentax but likely fall short of leaders like the 5D3, GH3, etc...

I'd be happy to be wrong on this one.

Basing on numbers given in specs (1GB=4.04min of 1080p30) it should be around 33Mbps, right?

Where did you see those figures in the K-3 specs (1GB=4.04min)? I can't find it anywhere.

K-3 video seems at first sight to be an updated version of K-30 video, i.e. with a few extra modes added. Imaging-resource provided downloadable originals of their test videos and from them, mediainfo tells me the following:

K-30 1080p video @ 30fps is 22Mbps VBR and h.264 @ high profile * CABAC, which isn't at all bad.
K-30 audio (mono track) is 512kbps PCM but only at 32kHz sampling rate.

I suspect that K-3 will roughly match the K-30 video average bitrate but I hope the audio will be sampled at 48kHz. I'll be pleasantly surprised if it goes as high as 33Mbps but I don't expect that because it would limit the length of videos to about 17 minutes. At 22Mbps, K-3 videos would have a maximum length of 25 minutes (because of the Fat32 4GB filesize limit) - which happens to be the specified maximum video length of K-3 (coincidentally or otherwise).

So 22Mbps is my prediction for K-3 video @ 1080p/30

Just scroll down to "Storage capacity/<Movie>"...
The 16 min 14s video is about 4GB, as you can see, but of course there is a sound recorded as well...

EDIT:
I just double checked the specs for the K-30/K-50 and they say 4GB is 16:21 (1080p30), so you're right it should be roughly the same.
