Aperture priority for shooting video, Lazy or smart ?

[ Edited ]

Disclaimer = Noob. 

 

Shooting video in aperture priority mode. Is this a good place to start ? 

 

I'm thinking with my shutter speed already determined by the frame rate of the video (double the frame rate for cinematic motion blur) that as long as i establish if i want a sharp or blurry background / foreground it narrows down the other elements that i need to take into account to get a well exposed video. So with shutter and aperture pretty much set all i need to focus on is ISO.

 

I'm learning the ropes to shoot music video's for my record label so i'm pretty much stuck on using 25fps (UK PAL)

 

Thoughts on this ? 

 

I won't list my camera i'd rather leave this a a general rule for any camera with aperture priority mode. 

 

Please don't be the guy who tells me to go and read the manual, Or use manual mode or nothing, That's what i usually get in this forum. I'm a beginner and looking for ideas on how to grow at my own pace with the HELP of more experianced users.

Lazy or smart?  Lazy.  I do not need to be the one to tell you to read the manual. 

 

Did you know why using a shutter speed that is double the frame rate does not give you "cinematic motion," whatever that might meant to you?  Have you ever heard of "shutter angle" before?  It is a way of describing shutter speed in a video camera.

 

For example, using a shutter speed that is "double the frame rate" corresponds to a shutter angle of 180 degrees.  Have you ever seen the beach landing scene in the opening of "Saving Private Ryan"?  It has a different type of "cinematic motion" to it, doesn't it?

 

The beach landing scenes to "Saving Private Ryan" were not filmed at "double the frame rate."  The camera director used a much higher shutter speed than the frame rate, one which was so fast that it capture no motion blur.  

 

You have much to learn, my friend.  You need to first become a good photographer before you can become a good videographer or cinematographer.  

 

Lazy or smart?  Lazy.

I have heard of it, call it 180 degrees if you like, I'll keep it simple and if i know i'm shooting at 25 fps then my shutter speed needs to be 50 (double).

I did not know that so thanks for the heads up. i might check it out

I do have much to learn i agree. That's why i'm here !

 

Feel free to suggest any tips on how i can fine tune this aperture priority shooting for video.

 

Lazy is fine with me if it's a more efficiant way of getting the results i need.

Lighting and shooting condition can vary widely.  YOU need to gain the experience to figure it out for yourself.  No one can teach you experience, my friend.  You have to work for it.  You have already shown that you do know even know the difference between the [Shutter] button and the {Video Start / Stop] button.

To get back to the original question at hand...  which was if aperture priority is a good place to start.

 

First, I'm not a professional videographer and have only ever shot family events.  The vast majority of such footage over the years was just with the cam on full auto.   But after I really got into photography, I started to pick apart my old footage to really understand what settings were being used.   One very common occurance I found was that any outdoor shot typically led to very fast shutter speeds which removed almost all motion blur.  But for my personal taste, I didn't like that particular look.

 

Fast forward many years and I now capture video still on consumer-grade cams, but I strive to use manual.  Here, I fix the shutter to what I want.  If I plan to use the entire zoom range, I'll pick the widest common aperture (cam has variable aperture of f/1.8 to f/2.8).   Or, If I know I'll stick with wide to medium shots, I may be able to keep the aperture at f/2.   Finally, will adjust gain for the proper exposure.

 

Having said all that, in faster run-and-gun, constantly fiddling with gain (ISO) is not fun, so I may go into more of a program mode.  i.e. I will control shutter and aperture, but then let the unit dial in its own gain.

 

Of course even that isn't perfect since the cam's choice of ISO may be bad (e.g. you're filming a scene involving a field of snow).

 

Hope that helps a bit.   In summary, I think maybe start in Program (P) mode and try that out.

HAHA - NO - If you think that then you clarly did not understand my situation !

Do not this forum to belittle new users to give yourself the feeling of being superior.

Nobody cares how good you thuink you are ! 

 

What i asked was when i assign the shutter button to record video how can i take a snap for custom white balance when in the same mode with all my settings in that mode. 

 

It's a simple question that you clearly do not have the answer to so maybe you don't know as much as you think you do my friend. 

 

Please feel free to have your say in the reply then kindly don't both to "help" me anymore.

 

Thanks

The camera does not do that, and I told you to simply press the Shutter.  No one is trying to belittle or insult you.  I simply stated an abundantly clear fact.  Thanks, for proving my point.  Good Luck.

You do need to tell us which camera you have because some of Canon's DSLR's work differently when used in Video mode and aperture priority does not work. (it reverts to an Auto mode)

Fair point Mike. 

 

 

I have the canon m50 - 50mm lens with speed booster

 

The reason i chose not to mention the model was i knew i'd be getting replies telling me it's no good for video etc etc. I know it's got great at video but with my budget it seems like a pretty good beginners camera. that's another story anyway :-)

I think the M50 is one of the many Canon cameras that will not do Aperture Priority in Video mode.  I believe it only does Auto mode or manual mode when shooting Video.
