@Steve: Some like the look, some may want to aim at showing it at a cinema... Or maybe they use different cameras and they generally use 24.

@Maverick: Cause Olympus doesn't care about video, and thinks anyone who does will buy a Panasonic anyway...

Yes, for the purpose of cinematic filmmaking the 24p choice is the option most people would like for their projects. I prefer this option as well.

The video on the Olympus EM1 looks great. Too bad they don't want to offer the 24 option.

ok fine, but I assume you're doing some editing to your footage, so why not just output to 24fps? Again, starting with 60fps (or 50fps from my camcorder) gives me the opportunity for nice slomo. You won't get that without dirty interpolation from a camera that starts off with 24fps.

Ok fine, but pulling down 30 to 24 fps will end up with very ugly stuttering. 60 to 24 could too. You'd need 48 or 72 fps to be able to do that, and if you want motion blur that makes it look natural and cinematic that will also be difficult when shooting at a too high frame rate. Basically a camera should support multiple frame rates, so that you can capture the right footage for what you are going to do with it.

kadajawi, you are to clever for a Pentax
See you somewhere selse with a good camera !
Those snobbish Pentaxists here are so boring and dull,
they just want to stay with themselfes only, bowing down to their Pentaxes.
This is a dying cult.

LOL

But I do want to know.
I would think any decent software can turn 50p easily to 24p or any other conversion?
48 frames, I believed, is a leftover from film days.
Personally I mostly shoot on 25p (cause my teacher tells me to) and if i want slomo, I go 50p.
If I do a small docu, I go 30p...

But I assumed that I can easily shoot 50p and convert anything from there with software.
(except that the pentax can't do 1080 50p... but that's another story)

@TomGarn: I'm also a Pentax elitist, looking down at Canon etc. Just not in terms of video...


@grispie: There is software that can convert the frame rates, but I don't know how well it works. 30 to 24/25 has always been an issue, and vice versa, due to cinema/PAL/NTSC (cinema to PAL wasn't such a big issue, they would just speed up the movie a bit). Of course today there are more possibilities, due to more sophisticated software and faster processors. Also there could be enough data in 50p to make it possible to get to 30p easily. 50 to 24... yeah, just slow down the video/audio a bit.


50i to 50p isn't that hard, there is a great deinterlacer for that, but it requires a lot of processing power.


@Steve: Too bad. I'd be curious to know if there is software that can do the conversion without any artifacts.

for this, I'd like to know which one that is? I have enough processing power, so I'll give it a shot.

In any case, regarding 50p,30p,24p,...
My personal opinion: I think the more you can set it up correctly while shooting, the better, no matter the software possibilities. So one can choose between always shooting at 50p or dial it on the desired fps while shooting.
I compare this a bit with post process coloring. the better you can put up the correct color profile and white balance while shooting, the easier it is afterwards and more importantly: it forces me to think & take decisions upfront rather then relying on post.

By the way, I shot someone elses short movie yesterday with a K3 (thus under good lighting, I think... We are still learning the craft...).
And I was really pleased with how the images came out. Very clean. I think a bit less cinematic though than what you can do with a canon or a GHx. I'm not supposed to do the editing, but I will pull the shots together anyhow just to see what it gives and do a bit of post on it. I'll show it up here where I'm done. And the K3 was a joy to use in a studio with M and A lenses (at the risk of being called a fanboy again :-). Even the canon dudes were impressed by the ergonomics of the K3.

So I intend to sell my Sony A77... Compare to the K3, the shots are softer and now I can understand why it was never really picked up as a camera for short movies. It is a pain to use in the studio, compared to a canon or the K3 for that matter. But this is why I am interested in efficiently converting 50i to 50p. The K3 can't do 1080 50p...
I'll use the money to buy some other gear instead. yes, maybe a small rig to do handheld...:-)
or a sigma 18-35 1.8...

Come on, almost any video editor or transcoder can de interlace easily using pretty much any PC now days. Try Handbrake, it's free and de interlaces without any problem.
If you want a file to try, download this 1080i .mts sample from Gordon Laing at (vimeo.com)/19504182

Yeah, but there will normally still be artifacts here and there. The IMHO best deinterlacer is QTGMC (QTGMC - Avisynth wiki), which really does an excellent job. Looks like 50p. 100%. IIRC (haven't had 1080i material in a while...) it gets me somewhere around 1 or 2 fps or so on an i5 with 4x4.5 GHz. It _is_ slow. But it is totally worth it. I've tried other deinterlacers and was never (this) happy with them.


I agree with grispie, choice won't hurt. Being able to convert around is good, but if possible it'd be nice to set the frame rate that you actually need... If I don't have much choice or don't know what I'm going to do with the footage later I'd rather shoot at higher frame rates though, that should also make conversion easier.

Not in my experience, but again - Do and use as you please - I'm only making suggestions based on that experience.
I have also used AVS Video Editor and currently Magic Movie Edit Pro. Results are 100% every time.
None of my suggested software are slow either.
