All 7D settings for shooting video
I've been trying to find a sticky or blog that really outlines all the settings or steps needed to achieve great video results. Not as a rule, but a starting point. I'm curious to see your thoughts on where I have arrived below and what you are doing different (if anything).
Normal Video Shooting: Frame rate: 30p; shutter speed: 1/60 Frame rate: 24p; shutter speed: 1/50 (unless HMIs, then 1/60) Frame rate: 60p, shutter speed: 1/125 or keep 1/50 or 1/60?) Highlight Tone Priority: Off I see more vertical banding with HTP on. ISO: Whole number: 100, 200, 400, 800, 1000, 1600, 2000, etc or: 160, 320, 640, 1250, 3200 (all taken from: Canon 7D ISO versus noise test images Marvelsfilm’s Blog) Color Profile I've been using Superflat and Cine Style. A great video demo can be found here: Click the link to the Vimeo page to download the scene files. Noise Reduction I've left this at Standard and haven't done any tests here to change it. White Balance I always try to set a temp instead of Auto. I've heard that Auto might introduce other noise or artifacts. Focus I always have the lens set to manual focusing for video and time lapse. |
David, do you have link to Cine Style. I have been using super flat.

Luka has all the downloads on his Vimeo page (in the description).
This is the direct link for the Cine Style from Martin's blog: Canon 7D Picture Style with Cine-gamma (S) Curve – free download Marvelsfilm’s Blog |
I don't know where that picture style1 come from but I have never seen bad video like that, I think he must put some kind of a dirty filter on it to exagerated the difference. (-:
All of the shutter speed is for normal, but hey if you are doing event with available light, do what you must to get the right exposure, go down to 30th if you have to, go up to 4000/sec if you outdoor and got no neutral density filter or don't have time to put it on, I like to use the K settings and change the white balance until it looks right, but if you are indoor and under extreme warm light, use the manual white balance because it will go down all the way to 2000K, the K settings only goes down to 2500K, shutter speed should be 160, 200, 320, 400, 640, 800, 1250, above that doesn't matter, the lower the better, I also use Marvel's preset but turn down contrast more all the way cuz I think it is still too black, everyone has different taste I guess. |
The super high shutter speed would only be set to maintain the shallow DOF, but you lose the 180° shutter to have any motion blur. I might be temped to adjust the aperture before the shutter speed (after I already set ISO to 100) unless I was going for that time-freezing feel.
I'm getting some ND filters so I can keep a "normal" shutter speed and wide aperture, but sometimes you have to do what you have to in order to get the shot. |
Am I missing something ?
I am in Manual exposure mode.
I can only change the shutter from 1/30 to 1/45 to 1/60 with the dial. Canon advertises that I can use ANY shutter speed. What am I missing ? |
I can go from 30 to 4,000 in mine set to 1080 30p. I haven't tried it in other settings, but I pretty sure it will in all of them.

CF1 - Exposure
I had to set Exposure to 1/3 stop. It was set on 1/2 stop for some reason.
Then I can change, but only in increments of 10, 1/30 1/40 1/50 |

Very cool, thanks.
So maybe I missed something. Is there a place to download your preset picture styles? If the software is no good then are there certain settings or something? |

I actually have been using the Super Flat, but will start doing some tests with the Cine Style too to see which will work best for me and post grading. |
I found the cine style from Marvel to produce strangely pumpkin-colored skin tones. Superflat seems better. I haven't fully explored why and I think some of Marvel's bloggers complained of the orangey tone and Marvel had some suggestions.

I'm interested to see if we have come to conclusions about the ISO and HTP settings.
Looking through the forum, some say HTP should be on, but not for low contrast picture styles. Others say on, but not above ISO 600-800. There are others that say HTP should always be on at high ISOs. Other blogs say to keep it off entirely. Also, ISO 320, 640 and 1250 were said to clip highlights, effectively the opposite of HTP. From reading, those ISOs should not be used with a low contrast picture style either. My question now is (which may require me to do testing later today): If we are capturing an image intended for post processing, do we use HTP, low-noise ISOs, both or none? Is there a rule for when to use some settings (indoor/outdoor/particular lighting scenarios)? I am using a low contrast picture style for grading, but it seems that HTP and the odd ISOs should not be used in that case. I don't want to clip highlights if that's what the ISOs are doing, but I don't want to introduce more noise in the clip. But, raising the low-end by a stop before compression would be better than raising in post (after compression) which is what HTP does. |
From Daniel Browning on other forums:
When you select "ISO 320", what the camera actually does behind the scenes is set the analog ISO to 400, then reduce brightness digitally with a -1/3 stop pull. That makes it look as if you had used ISO 320, except that 1/3 stop of highlights are clipped. The upside is that noise is less. It's like the opposite of HTP (highlight tone priority). HTP sets the analog ISO to one stop below whatever you pick, giving 1 extra stop of highlights, then increases the brightness digitally with nonlinear EC (to preserve highlights), which increases the visibility of noise. So HTP trades shadows for highlights. The other tweener ISO settings (125, 250, 500, 1000) should be avoided, because they do a 1/3-stop push, but don't bother to preserve the highlights, so they increase noise for no benefit. ---- • 100, 200, 400, 800, 1600: normal amount of highlight headroom. • There is little difference from ISO 100 to 200, because most viewers can't tell the difference in photon shot noise, and the read noise drops by almost a full stop in ISO 200. • 125, 250, 500, 1000: considered harmful. 1/3 stop less highlight headroom and 1/3 stop more shadow noise. • 160, 320, 640, 1250: fine, as long as you are aware of the decreased highlight headroom. (Clips 1/3 highlights to get 1/3 more shadows.) • HTP should *always* be enabled when the ISO is higher than 1600. • There is a careful balance between increasing shadow detail through ISO (which clips highlights) or through HTP, the picture profile (e.g. contrast, tone curve), or Auto Lighting Optimizer. Generally, the higher you go in ISO, the more beneficial it is to use non-ISO methods to increase shadow detail. For example, ISO 3200+HTP (actually ISO 1600) is better than the real ISO 3200. ISO 800+HTP may be better than the real ISO 800, but it depends on how much highlight headroom you need. |
Just a quick update regarding 60p settings:
1. When shooting 60p to use in a 24p(23.976) timeline for 2.5x slower motion than realtime: Shutter speed: 1/120 2. When shooting 60p to convert to 24p for realtime playback in a 24p timeline: Shutter speed: 1/60 (closest to 180° shutter speed of 1/48 in 60p mode) At least this is what I am testing now... |

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'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? |

Sweet guys. I have a few scenes setup to go through some filmmaking 101 too (although I am explaining lighting scenarios in all the scenes). There are a few surprise characters involved, but I really want to focus on creating that "cinematic" shot.
I'm planning on showing some tips with footage in Final Cut Pro as well as After Effects if that doesn't seem to far away from the filmmaking side of things (going back and forth from live action to screen capture on the computer). |
RAW, L, S etc..?????
I've seen tons of posts about messing with the picture settings (sharpening, contrast) .. My question is does it matter which quality setting you use in movie mode? Will RAW produce a better image then the L setting or is there a default value set by the camera in movie mode?
|
Original RAW image data is never changed by using Picture Styles or other controls in the camera. These styles and/or settings in camera only affect JPEG or h.264 files because the camera is converting those images on the fly to a compressed file. The RAW image file includes data detailing your camera settings, but can be removed or changes with RAW image editing software (Bridge, Photoshop, Aperture, Lightroom, etc). For JPEG and movie files, you don't have wiggle room to change later. That's why it's best to have the camera create an image with as wide of a gamut as possible so you have room to compress later.
Try this: Neutral (picture mode) Sharpness (all the way down—left) Contrast (all the way down—left) Saturation (down 2 notches—left) You may want to do some tests to see what works best for you—especially if you don't want to do post color correction on your videos. All of this "flattening" is to give you the best possible image to grade later, but doesn't look good if you don't color correct later. PS: When shooting RAW, your white balance doesn't matter. You do need to pay attention to this with JPG and movie files. AWB should never be used for video. |

OK.. Im sure is was a newbie question but I just upgraded from a T1i and full manual control is a whole new world .. i got so use to trying to manipulate to exposure by pointing the camera at a dark or light spot on set.. but maybe its me but the T1i seems a lil' sharper.. Am i smoking crack or what? im still playing around with it, ill be running test all weekend.. i'll post results later
|
Gerald, are you asking about Picture Profiles or image quality (Raw, sRaw, Jpeg, etc)?
You can only shoot quicktime in movie mode (h.264), but you can shoot anything else in photo mode. Brian, what do you mean you can't record Raw? Raw stills! ;-) About the picture profiles: It doesn't matter what your picture profile is when shooting RAW. It does matter what your end goal is when shooting video or Jpeg (do you want to post color correct or not). As far as the sharpness, I really believe there is some enhanced sharpening by default with the T1i or at least that the scale is different from low to high. To get images that don't seem as soft on the 7D, try upping the Sharpness in the picture profiles (pick one) a few notches. Maybe you should take a photo at every picture profile and at each sharpening adjustment to see the difference. My take? Canon made the T1i sharpen more digitally in camera for consumers and the 7D more "normal" as the pro Photoshop photographers always unsharp mask anyways. Update: Try setting the 7D's sharpness to 2 to match the 50D and 3 to match the T1i. Other people have noted that the anti-alias filter is a little stronger relative to the individual pixels on this sensor (compared to the T1i or 50D). |
oh believe when i say im not comparing the T to the D .. there's much more detail in the imagery .. I'm doing some scene tests this weekend. i'll be sure to post my results when done.. So far, im not mad at the 7d..

It's been a month - hows that training video coming along Dave ?
|
Hey Andy,
It's actually coming along really well. I should have a site up soon with a "preview" of the video. I'll keep you guys posted on here. |
David,
You mention using whole number ISOs instead of 160/320/640/1250, which show the lowest amount of noise with the cap on. What is the reason for this? Thanks. |
