On mt 7D, I just verified that when in movie mode, set to M, that I can go 30, 45, 60, 90, 125, etc....

Where is 1/50th?

You have your camera setup for 1/2 stop instead of 1/3 stop increments for exposure.

Menu > Custom Functions > Exposure > Exposure level increments > 1/3—stop.

If you have made settings that you are unsure of when you first started, just clear all custom settings and clear all camera settings.

Thank you David!

To avoid flicker when shooting under artificial especially fluorescent lights the shutter speed for 50Hz PAL land should be 1/50.

Nigel is absolutely right about that.

One thing to bear in mind (at least when in PAL settings/countries) is that the 720p mode on the 7D only seems to let one shoot with a slowest shutter speed of 1/60th (= no good for any indoor stuff where fluorescent lights are around due to the horrible "strobing" you get). 1/60th is of course fine in NTSC/60Hz countries to avoid this effect but no good here in the UK! I can't get it to 1/50th in 720p mode when set up in PAL (but 1/100th would work to avoid this effect...or any multiple of 50 but of course... but just gives less motion blur/can look too "steppy".... so I tend to like those type of shots at 1/50th).

Maybe I missed a setting somewhere? (only had the 7D a couple of days) so if anyone knows how to get 1/50th shutter speed (with 720p 50fps) let me know! No real worry for me as most of that stuff I'll do on my EX3 anyway but it would be nice to have the choice to do that type of indoor shot on the 7D too.

Andy, I believe you are correct. Unless the setting for shutter speed increments is 1/2 instead of 1/3 by chance, I don't think the camera will allow slower speeds than 1/60 even though you are in 720p50.

The 180° rule for 720p50 would be 1/100th anyways, right? I know that doesn't work in my theory of shooting 50p and converting to 25p for realtime and keeping the shutter 180° to 25p for real time.

Anyone tried the Genesis Panalog PS?

I'm about to start some comprehensive testing with all frame rates and picture styles to compare various workflows to grade, transcode and various methods to minimize skew.

I'll put everything on vimeo. I guess it will be more of a video explanation of all the settings and should help out others with "seeing" the difference between various settings.

David

I, for one, would be really interested in seeing that.
Look forward to it.

That would be awesome, thanks David!

That'd be great. Looking forward.

I'm working in UAE and only 1/30 and 1/100 shutter speed worked under fluorescent light.

My testing is becoming so comprehensive, I'm thinking of turning it into a training video:

"Independent Filmmaking and the 7D"

While I'm not a news journalist or documentarian, I do have a background in visual effects and video production—which should make this very interesting (green screening, motion tracking, basic and creative lighting, etc). I'm covering all of the "tech stuff" for some of the photographers coming into video but aiming to present it all visually so you really understand what looks like what and which rules to keep in mind.

What would you guys like to see covered?

Here are a few topics:
Bare necessities for 7D filmmaking (not the endorsement list!)
7D for Run N Gun
Lighting your scene for the 7D
Shooting for post color correction (grading)
Shooting for green screening
Getting that shaky cam without the jello
7D vs EX1 comparison

I didn't want to just explain camera settings, but rather show you how I shoot, edit, grade and deliver. Any thoughts?

Green screening, lighting, EX1 comparison.

I vote the following in order of preference most to least...

1. Lighting your scene for 7d
2. Bare necessities for....
3. 7D vs EX1 comparison.
4. 7D for Run & Gun
5. Getting that shaky cam...
6. Shooting for Green Screening
7. Shooting for Post Color...

Do a really good job, post it somewhere and charge people $20 ($10 for your Dvinfo pals! <wink>) and I'd pay...
