Hmm maybe I should just leave this little question unsolved, as itis not because it is of any real problem to me.

BTW: Could someone tell me what 'washing' the frames in editing means (as TheoSixx mentions above).?

I am talking about the well known and often discussed MOVIE technique, where you trick the Pentax K-x to maintain ISO and shutter speed in video mode, by fist choosing P mode and locking the shutter speed before dialing to video mode.

My question is: Some people talk about selecting 1/50 and 1/25. But I can only select 1/15, 1/20, 1/30, 1/45, 1/60 etc. no matter what lens I am using..?

Is there a difference between european models ann US/asian models regarding shutter speeds..?

Thanks for your opinion on that, TheoSixx. You may be right, but I am a novice and not the one to judge on that.

I do not believe in Santa Claus, but I do believe, that frames without motion blur gets me closer to a cinematic look that I am after. I have no experience with 'Washing' the frames. That sounds like an interesting technique.

But with all that said, my question is still unanswered:

Why does some people refer to selecting 1/50 and 1/25 in P mode, when I am only able to select 1/15, 1/20, 1/30, 1/45, 1/60 etc.?

Thanks, TheoSixx.

I am living in Denmark (Europe). So I guess I am from 'Abroad' and therefore I should have the PAL version, if such different versions exists..

But my video is shot at 24 fps, and I can only select 1/15, 1/20, 1/30, 1/45, 1/60 etc. as mentioned above..?

Sorry..

I am only talking about shutter speeds that you can select in P mode, before locking ISO and dialing to movie mode.

I only see is 1/15, 1/20, 1/30, 1/45, 1/60 etc.

But I often see people talking about selecting 1/50 and 1/25.?

All over this forum people write about choosing aperture speeds like 1/25th and 1/50th when shooting video on a K-x.

I own a K-x and I do not see those f-stops.

What I see is 1/15, 1/20, 1/30, 1/45, 1/60 etc.

It is not really a problem. I choose either 1/45 or 1/60 for video to get as close to 180 degree shutter. I am just wondering why everyone else seems to be able to choose eg. 1/50..?

Can someone explain it for me?

Hi there,

I need advise from more experienced video-shooters.

I have the KX with kit-lens.

Additionally, I have the following line-up of (fully manual) prime lenses:

Vivitar (Tokina) 17/3.5
Pentax 50/1.7
Ricoh 28/2.8
Ricoh 50/2
Ricoh 135/2.8

Tokina 24/2.8
Tokina 200/3.5

I also own a couple of small zooms, that are not very fast, but might come to use in som weird video-situation.


Obviously, the 50mm is perfect for low light and crisp portrait etc.

My question is more towards the 17 and 24 mm lenses.. I just love the look and feel of those manual lenses, but that is also due to pure aesthetics and me wanting to look cool! :p

They are not faster than the kit lens.. They are a challenge to focus (small viewfinder), and the image quality is not better to my eyes.

I would like to travel with a not too heavy bag, and I both want to do lots of photos, but also some small videos on a tripod with controlled ISO.

I know how to trick the ISO to stay at 100 with manual lenses. Will I be able to do the same with the Kit lens? Should I leave all but the 50mm and the kit lens at home?!!

Setting Shutter Speed for Video (A How To Guide)

Thanks for all the info everyone!

Every now and then in this thread a shutter speed of 1/48 as a possible good option for shooting video at low light with ISO 100.

But.. on my KX I have only the options 1/20, 1/45, 1/60, 1/90 etc..

How do you set the camera to 1/48 (so it fits the 24fps)???

Also: Can someone please explain to me, why I get interference from electric lights at some shutter speeds above 1/60 (I live in Denmark and the electricity is 50hz)?

And also: In broad daylight, sometimes when I shoot a Bus driving by at 1/60, it is 'jumping' instead of driving, whereas if I release the automatic gain (the asterix), it is driving normally again..

I hope you understand my broken english!! ;-)

Thanks,

Ronald


oh and by the way, my gear is:

Pentax KX, Pentax smc 50mm 1,7 M, Tokina 24mm 2,8, Tokina 300mm 3,5, Ricoh 28mm 2,8, Ricoh 135mm 2,8

I only shoot manual, until I can afford a 10-20mm (which I only know of as automatic..) ;-)
