To doublevr's questions, I would say yes we should keep filming the way it currently is.
I think it comes down to 2 mains issues.
1. Quality
2. Offline implementation of PT AI
First, like the majority here have stated, the quality is currently not up to par and I feel, should not be switched just because it it's getting "better" but rather should be considered once it is the "best" option.
Second, the next most common complaint I have seen on here is offline implementation of PT AI in a way it is currently working for PT content downloaded offline. I am a trucker and download all of my videos including PT to use when on the road for weeks at a time. I do not have a stable connection most of the time so almost all my PT is used offline except when I am at home.
Unless PT AI is enabled offline through DEO client side, I'm sure many would appreciate the option to still have PT filmed videos for their offline usage.
If and when PT AI is able to be implemented to a degree that is equal to or better than it is currently manually filmed AND able to be implemented client side for offline content as well then I think the switch would be almost universally accepted.
