Yes, if you are using a video camera to take photos, it would be on topic. The reason for this is because conceptually, there is a fundamental difference between the needs of photography and video. They are related, but still different enough to merit separation.
Put another way that is a little more everydayThat said, when you are taking a photo with a smartphonewe have very few "pure" devices these days, isso it a phone or a camera? It is ahard to define the type of device that is a hybrid. It can be moreby anything other than one thingit's use case. It can be a phone that you talk to people on A smartphone, it can be a PDA and it canfor example, could be considered photographic equipment since, in many cases, they have a camera. The simple fact that it is a smartphone doesn't mean that it is purely a phone or even that shooting photos with it has anything to do with it being a phonerivals the quality and capability of many point and shoots.
Conversely This however, the fact that a smartphone can be used to take photos does not then mean thatmake it on topic to ask how to setupcheck your e-mail on your phone is on-topic, even though a smartphone could be considered photographic equipment.
Similarly, modern Modern cameras often have video functionality in addition to still. The device is a hybrid, both point and simply the fact that it is called a still camera (if it is in-fact called a still camerashoot and not just a camera) doesn't mean that it is operatingDSLR, are similarly hybrid devices capable of use as a still camera when shootingeither video or still cameras.
If AVP didn't exist, then I would be more inclined to agree that video related questions for still cameras should be allowed here, but since there is a site dedicated to audio/visual production, it is a much better fit there as it really is not photography related.
It's also worth noting that even professional video often uses DSLRs now, so your question is very likely to get answers on AVP and at least one or two of us on Photography also are contributors over on AVP.
As for the clarification, I'm not 100% convinced that it is a necessary change. I think that withing the field at least, the distinction between a camera being used for photographic purposes and a camera being used for video purposes are distinct use cases. I don't know any videographer that shoots on DSLR that would say they think what they are doing is related to photography and they would consider their rig a video rig, even though the camera is still perfectly capable of being used as a photography rig with a different (or maybe even the same) configuration.
