Change the shutter speed on the 7D?

Hi, I have a Canon 7D and am going on my first semi-professional video shoot on Sunday. I don't have the know how yet to shoot in manual mode so I thought that shooting in tV mode would be best so that I could control the shutter to 1/50 (shooting 24fps). So I switch the camera to tV - hit the "Q" button and dial in the shutter to 1/50...but then when I switch to movie mode, hitting Q no longer lets me change the shutter etc. Is it impossible to do within movie mode and I have to keep switching back to photo mode if I want to change it for an effect etc?

Any other suggestions?

Thanks!
 
You shouldnʻt ever have to press the q button to adjust the shutter, iso, or aperture.

The scroll wheel on the top right of the camera controls the shutter and the iso when you press the iso button. The circular scroller to the right of the screen controls the aperture.
 
Yes, I've noticed that but it doesn't seem to always work - sometimes it updates the LCD with the new shutter in whichever way I scroll...and sometimes nothing happens...and I have no idea why. I prefer using the Q so I know that it takes the new setting.
 
I'm sure its just the camera settings, It took a little bit for me to learn how to operate the camera in manual mode but it is necessary. If you really do believe it is the hardware malfunctioning contact Canon.

In video mode, every shooting mode is automatic except M.

Really?! This I did not know! So there is no way to run the camera automatically and simply select for shutter speed (tV mode)?

I guess in manual mode I could set the shutter to 1/50th and the iso to automatic...that should pretty much work to take the worry out of it until I get the hang of this stuff right?
 
If you're shooting 24p, 1/50 is a good shutter speed if you live in PAL land. NTSC folks should stick to 1/60, in general.

Read up on exposure. Practice with stills. Check histograms. Experiment. There's little point in shooting video with a DSLR without manual control.
 
Just curious why 1/60th - I've read conflicting reports before but decided to go with bloom's advice on his training DVD to always set it to double the frame rate. I'm shooting 24p and since I don't have 1/448 I shoot at 1/50...no?
 
You're correct about the 180 degree shutter; however, flickering is a possibility when using 1/50 in NTSC or 1/60 in PAL areas.
 
When you say flickering do you mean because of florescent lights etc. that run at 50hz? -- If I'm using tungsten studio lights etc. this shouldn't be a problem, no?
 
I don't know which lights do not cause problems. That's why I said, in general, it's a good practice. I've heard that street lamps can cause flickering or banding and that's an example of a situation which may not be so obvious on the LCD.
