Even though I love both, and would wish for more non pov content, I see some difficulties here.
- Keeping it non-pov, the directors prefer to keep the cam moving which is great tbh but is limiting with the cameras and equipment they could choose. That's why a lot of lower quality 5k and 6k content is produced.
- Those using toys might not prefer the non pov view. Have noticed this quite often in comments.
- Moving cam needs perfect stability. A few studios do it right but quite often they do mess up. And it's another piece of equipment that eats up their budget. Most have this jitter or sudden movement, that would throw off a lot of users.
- Lens focus/sharpness is a big issue even for fixed pov scenes. Heck SLRO had its fair share of issues.
For fixed non-pov, the models keep moving a lot with positions, etc. It gets tricky for the director to keep everyone in focus i guess.
Gets worse with focus issues if it's a moving cam non-pov scene.
Studios are picking the low hanging fruit here, so understandable seeing so much of pov content.
Give it time, it'll grow as the vr space grows.
