They collected data, which was identifiable down to the household, and sold this data. This data consisted of the family viewing habits, including the specific shows watched, the times watched, and so forth. They used pixel sampling matching, so that they know if you are watching a DVD, or video from your computer, and can tell what it is.

Presentation: Wally Cherwinski on iPhone videography.


Dr. Wally Cherwinski is a Videographer based in Ottawa, Canada. Originally trained as a scientist, he spent a portion of his career in research and teaching at the University of Cambridge, England while doubling as a freelance photographer and writer. Later, he joined Canada’s National Research Council and spent many years managing communications for the Canadian Space Program.

Starting with 16mm film, he has written and directed numerous documentaries and television features, including projects with Canada’s National Film Board. More recently, he has combined his passion for video with his love of travel.

Wally has been a Mac user since the original 128K in 1984 and his Apple “museum” includes over 30 Macs (not to mention Newtons, iPods, iPhones & iPads). He has delivered video workshops at several Macworlds, at Macintosh User Groups in the U.S. & Canada and on three MacMania cruises. He also writes a regular video column in the ScreenCastsOnline monthly magazine.

On holiday, most people take a lot of photos, not so much video. We are used to taking pictures, but not video. 

A few years ago, you would have to buy a dedicated video camera (expensive) and carry it with your still camera.

But now, both still and video are built into smartphones, especially the iPhone.

Video is becoming more popular. People are doing one-off clips, posting to Facebook and other social media.

iPhone Video to Go

A photo snaps an instant of time

Clip captures moments

Video captures stories.

“The best video camera is the one in your pocket” — smaller video cameras are better than big ones, when capturing spontaneous stories.


light, portable

good optical quality

shoots 4K

Slo Mo, Time Lapse

and has good accessories

But no continuous zoom

weak in low light

screen hard to see

battery life problem

In photos and camera settings, you have four choices:

720p at 30 fps

1080p HD at 30 fps

1080p HD at 60 fps

4K at 30 fps

A minute of 4K takes 378 MB.

Hold the iPhone horizontally. A round red button means you are not recording, a square red  button means you are recording. The round white button allows you to simultaneously take a photo. 

A 4K image is 3840x2160 pixels. By shooting 4K, you have the ability to crop the 4K image into three versions of the same scene at 1080p presentation.

The still photos are basically an 8 MP photo, but that is not bad. 

Apps like SnapMotion will extract still photos from a 4K video.

For editing, Wally hates iMovie, but does like the trailers feature of iMovie. Day to Day editing, he uses FCP X. 


1. iMac headphone jack mutes all audio when the headphones is plugged in. No sound at all.

something goofy happened — we do not know.

2. updated iPhone to current iOS, and found the location services icon is always there. Can I suppress the location services?

You can turn location services off in general, or app-by-app.

Look in settings -> privacy -> location services.

By the way, location services does suck up battery power.

3. I have a bug in preview that prevents me from adding or removing notes from documents. What is the best solution for annotations?



4. When I plug my iPhone into my MacBook Pro, it says “not trusted” every time. There is no prompt on the iPhone.

Just use touchID or passcode entry to get the iPhone to accept the MacBook Pro.

5. What changes is Apple making that could cause old applications from running?

The app trust certificate might expire unexpectedly, because of developer neglect.

32 bit is being deprecated, again because of developer neglect.
