Sangwhan: travis had something on the naming - 2 properties returned - smooth and power efficient - frame rates- fractional nuumbers delivered as strings - they are reconsidering as 2 integers.

Alex: why not floats?

Sangwhan: they said floats dont cut it. but it's being reconsidered from strings.

Kenneth: comment 21 days ago that they updated the PR but we haven't followed up.

Travis: I'm skeptical of how useful this is going to be in practice. A UA might be able to tell you whether it could play smoothly or be battery efficient but there are a lot of factors...

Hadley: re battery efficiency -- could be important for older devices and developing/less wealthy countries.

Alex: this is one of those trade-offs where it's highly invested eng teams vs the common case. Big media companies would need this.

Kenneth: but it is bad for the user if you're draining their battery - bad for the web. This seems like something we need to have but is it done the right way? Could be especially useful for VR media...

Dan: is this in fact useful in other domains besides high volume video? Maybe get feedback from VR people?

Alex: there might be some but [it's a different medium]... Potential benefits might be different. we could ask them if they are paying attention to power at all.

Dan: XR folks will be requesting a review soon so..

Kenneth: what about amazon / hulu / netflix? Also BBC.

Dan: we could reach out to talk to Mark... (AC rep for netflix).

Kenneth: we could get feedback from 2nd screen working group....

Alex: And Web & TV folks

Yves to work w3c contacts.

Kenneth: let's get feedback and from that feedback we figure out what we do
