Pentax K-3 Video Discussion

AFAIK, the GH3 (or was it GH2?) is one of the very few exceptions which do not subsample. It uses the sensors full resolution to supersample video. IMHO, this is the single most decisive detail to make a still camera stand out for video.

With the D800, most people state that the quality out of cam is good enough and the uncompressed output not really worth the effort.

But the real new kid on the block below $1000 is the 10 Bit ProRes codec for video, such as offered by the Blackmagic pocket cinema camera. Another opportunity missed by Pentax.

Wasn't it that the 5DIII uses pixel binning for a video?

Yeah, that's a real interesting camera for sure. They plan to offer RAW video too. That's a lot of data to process, but they've optimized their pipeline with a Super 16 sized 1080P HD sensor so there's no need to sample or bin or otherwise deal with a 20MP datastream coming off the sensor at 30FPS.

I doubt that most Pentaxians would be happy with a 2MP camera with a 3x crop factor; we'd likely get more "Pentax is doomed" messages LOL.

I would though...

i think i can live with no "SR" thing as i always use tripod/monopod.

im very curious about k3's bitrate..if it stands out or atleast closer to a 60d up to 5dm3..then it's worthy of my money, i currently use my k-01 in video works but not really happy with its bitrate as there is a massive quality loss compared to a 60d.. i wish there would be a in depth review with its video capabilities.. or if they would give me one..i'll be very happy to test it!

I was just reading the preview on Imaging Resource and he had this quote "one thing that still seems to be absent, though, is autofocus during movie capture. That means you'll still have to pull focus manually, or set your shoot up so as to keep your subject within depth of field. It will, at least, be easier to do so with fully manual exposure control." Is this true? I thought that was one thing Pentax fixed with the K3?

I saw that too but can't confirm. That may be a deal breaker for me, unfortunately. I don't use AF with video often, but face detect AF is useful when shooting interviews.

Steve.Ledger · 10-12-2013, 02:18 PM

I don't think AF during movie recording was ever officially listed as a feature of the K-3.

bass3587 · 10-12-2013, 03:25 PM

Knowing me I probably misread it hoping that it did have AF during movie recording. I'm sure it will be an improvement over the K5 anyway.

Steve.Ledger · 10-12-2013, 04:15 PM

I've read a lot of K-3 feature reviews starting with Adam's, and none mention AF during Movie recording, so don't get your hopes up. For most of us, noisy AF lenses would ruin it anyway, besides - you will will find a lot of pro videographers will say no to AF and zoom while shooting video. Short takes are always more pro looking.

bass3587 · 10-12-2013, 04:43 PM

Thanks sledger. I rarely use video but it was something we are thinking of getting into, plus I plan on using my manual focus lenses for video anyway. Oh and if you don't mind based on the lenses I have in my signature do you think the A35-105 would be a good choice?

Steve.Ledger · 10-12-2013, 06:11 PM

I wouldn't have a clue, I've never owned that lens.
Seems like a good one for stills - but video is quite another matter.
Anything relating to lens choice with a K-3 for video mode is purely speculation right now.

The specifications for the Q10 and Q7 don't mention autofocus during movie mode but support it. So we shall see.

Steve.Ledger · 10-12-2013, 07:46 PM

Derek, the Q10 and Q7 do mention AF during movie mode both in the manual (P108) and on the RICOH product site.

(Pressing OK performs AF during movie recording)

It would seem to me that AF on a Pentax dSLR during movie mode would be right up there with the selectable AA filter as an exciting new feature. We'd be hearing a lot about it.

I wouldn't be too bothered about no AF in videos, if the Nikon D7100 test videos are anything to go by. Most of them when using its AF look amateurish, it often focuses on the wrong thing momentarily when the camera is moved or objects in the field of view move, and that would just drive me crazy. But having priority and manual control of video and audio available on K-3 video will be a big plus for me.

I see it there, but not in the specs. I have seen it in the manuals.
