Canon 70D help on shooting movies

I am kind of struggling with understanding how to effectively shoot movies on the Canon 70D. I have the 18-135 IS STM lens.

I think what is causing me some frustration is understanding the Shutter speed in comparison to the Frame Rate (30FPS or 60FPS) when in Movie mode. How does shutter speed factor in? Isnt the frame rate taking over at this point?

I am only a hobbyist mostly shooting family life events, so I am just needing to take smooth realistic looking video...how do I achieve this?

My movie mode settings is at 1920/30/IPB

Lastly, when I do shoot photo's I try to shoot mostly in Manual but if time isnt on my side, I will change to T or A as needed.

Shoot at 1/60 for your given situation(30 fps). IT'S CALLED THE 180 DEGREE RULE.

The 'general' rule is set the shutter speed at double the frame rate. I mostly shoot at 1920 x 1080 at 24fps so I 'usually' set my shutter speed at 1/50th second which is close enough to 1/48th second. To gain a more natural looking video there needs to be a bit of motion blur with the subject.

Naturally all rules can be broken.

Thanks!

What happens if I shoot at a higher Shutter speed like 1/500 etc...will the playback be really jittery?

Yep, really choppy. The initial sequence in the movie 'Saving Private Ryan' was shot that way.

fun fact, with magic lantern it can get you 1/48 exactly you just set it to 1/50 and it will drop it down automatically a bit to get 1/48.

Not so much jittery as jagged. If you freeze frame a moving subject like a person walking by or even a moving car you'll notice the outline of the subject clearly defined, no subject motion blur. This may suit still photography but with motion photography you need a bit of motion blur for a smooth transition from frame to frame.

If a fast shutter speed is used the edges of the subject being clearly defined will look jagged as the subject moves in relation to the background (or foreground).

I hope this is clear as it's the best way I can explain this.

nice to know as i was shooting some moving cars at 1080p and 25fps and i assumed i use it like when taking photos, i was between 1/650 and 1/1250 so i will try 1/50 next time.

Fast shutter speed is ideal for, lets say, blasting effect. It's kind of an effect to see details with blasted objects or alike. Some motion pictures use high shutter speeds like saving private ryan. Notice when a mortar is blown into the ground and you can see the details of the soil going up into the air, and see the shells popping out from a machine gun. Slower shutter isvery good in making a slow motion effect as well.

Try both. One of the great things about digital is that it costs nothing to play around and experiment.
