Although the anemometers were displaying FPM, they are capable of displaying CFM, and that was probably the basis of the narration about the duct CFM.
I believe he is using a unit like this:
He was reading FPM & calling it CFM because it would have been impossible to deliver that much CFM through that duct & diffuser.

Here is how a show (any show like this) is shot.

Often, the scene is edited later so that it appears that the host is speaking while standing near the tool, device, AC register, what have you, when actually, it was done later in an ADR studio at a mic in a sound booth.
My point is that the CFM reading was probably made BEFORE those scenes were shot, and the director just said "turn it on and talk about numbers" so that it represented the previously obtained data.
Directors and editors are NOT HVAC pros, nor do they care if FPM is being discussed by the guys on camera while saying "CFM."
There is always a schism between what is being shown and what is being said. Sometimes it is very minor. Sometimes, a guy with training like you or me might notice, "hey! That's feet per minute, not CFM, DUH!!!"
But on TV, it's not a big deal.
How do I know this?
My second major was film and TV. I did radio over a span of 19 years, and I still do a lot of voiceover work. In the past 6 months, I worked on two projects for medical stuff that had three separate re-writes to get everyone satisfied. It happens.
Here is my favorite project from 2009. I'm the voice over.
That was excellent voice over, you should be in demand.
Are you a hunter, too?
When at the college, I did TV productions including writing the script, the story board, directing & operating the board & calling camera shots at the same time for one show; however, even when using voice-overs, the content needs to be accurate.
Actually, it was the H-VAC guy that said the numbers he was looking at were CFM when those numbers were actually FPM velocity. That totally misinforms anyone watching that show. Mike Holmes wouldn't allow those gross errors in other areas of his expertise.
In the last show Sunday, 09/04/2011, they they did similar if not the same airflow checks & never said what the numbers were. It was a rerun, so did they edit the part out?
It IS possible.

In the Deer Off spot, I really enjoyed the performance of the woman. She reminded me of Jane Curtin.
I used to do a little hunting, but not much time to go out in recent years....
I watch his show anytime I get a chance. I find it entertaining but not always accurate.The sad thing is that the viewers for the most part do not know the difference.Besides the error of fpm and cfm, I loved the fact that the dryer vent was reinstalled incorrectly to code as well.His show has so many code violations that I enjoy watching it to see how many violations there are going to be in each episode. Mike is sold on spray-on insulation and solving all of these types of insulating problems.There are so many errors when it comes to vapor barriers,mold and condensation that it is rather quite amuzing. I certainly would not consider myself an expert in all phases of construction but after spending 33 years I do know enough to ask the right questions. I will continue watching his shows but the editors need to check the accuracy before releasing the episodes.
I would imagine there can be significant differences between US codes and Canadian codes and guidelines.
