Let's hear your ideas, people! Some of these might be things you expect to happen in the next few years, or maybe as far out as the next 10 years.
Personally I am super stoked for the next 5-10 years in camera video tech. We're all used to improvements on the hardware side and that will continue of course, but with more and more image processing advancements happening in software I predict we'll start seeing a lot more features coming from advanced processing techniques combined with new hardware, like the GoPro 7 hypersmooth.
Ok let's get started. I've chunked up my predictions into some major categories but feel free to add your own if they don't fit into these:
There's been a ton of innovation in AutoFocus over the last 5 years and I think we'll continue to see more, including more stills AF features making it to video, like runtime eye-AF which is now shipping on the Sony A6400 and upcoming A9 firmware update.
Face registration with priority
This is another existing stills feature that we don't have in video yet (to my knowledge)
3D Focus tracking?
Generating 3D models from multiple high resolution stills (photogrammetry) is tech that's in common use right now in a variety of fields (e.g. Google Earth)
It's reasonable to imagine that with enough processing horsepower and good software a camera could build a 3D AutoFocus model of a subject (rotate around subject to get data)
With a 3D AutoFocus model it's possible we could have highly accurate tracking even as a subject moves / rotates in space
Sensor / Resolution
I'm not super well versed in sensor tech so below are some of my layman's predictions. @androidlad, wanna chime in here?
High-res quad bayer sensor which combines short and long-exposure pixels into an HDR frame. This is a feature on recent smartphones (see EOSHD thread)
Sony's STARVIS Micro-4/3rds sensor does quad bayer HDR already for video
Full-readout 8K with 4x Clear Image zoom?
The Sony A9 can already do 2x Clear Image Zoom without any noticeable loss in quality (example)
With a full readout of an 8K sensor (33.2MP) downscaled to 4K, we could get 4x Clear Image zoom while still outputting a full-res 4K signal
Imagine being able to use, say, the 24mm 1.4 GM as a 24-96mm 1.4 zoom lens. Sounds pretty sweet to me
In-camera image-processed stabilization (a la GoPro 7 hypersmooth)
I've got a GoPro 7 and this stabilization tech truly lives up to its name. All done in-processor in realtime in 4K right now (albeit with a much smaller sensor readout). Bringing this tech to larger-sensor cams seems like a big win
Codecs / Compression
10bit 4:2:2 / higher bitrates / blah blah
Already here in the GH5, only a matter of time before it trickles down to more cams
Lossless compressed RAW (a la BlackMagic RAW)
I could see some other manufacturers making their own version of this type of codec, and maybe selling it as a paid firmware update on prosumer cams for those users that want RAW
4K 60p is already here on APS-C, 120p seems reasonable in 5+ year's time with enough processing power / heat management
Realtime encoding features
Already on smartphones and the GoPro (which works great - example)
Simulated Depth of Field
This is already a stills feature on modern smartphones and it works pretty well (Google's Pixel portrait mode explained).
Not super exciting for those of us that like real bokeh from fast lenses on large sensors but I could see some smaller action cams / vlogger cams making good use of this.
Ergonomics / Body / Usability
Smartphone touchscreen performance
It's a travesty that we still don't have this level of performance in our camera touchscreens given how long smartphones have been doing this well
Smartphone-style touchscreen interface / usability
Again a travesty that $3500 cameras are light years behind a $200 smartphone UI. Leave the legacy UI mode for people who want familiarity but give us a proper 21st century UI.
This already exists on higher end models like the Sony FS5. Obviously this is a much larger body with an APS-C sensor and I'm sure the current system wouldn't fit into an A7/A9 body, but maybe we'll see some miniaturization of this or some kind of on-sensor ND tech.
Clear Image Zoom on focus ring
Ok this is a small idea but imagine being able to swap the functionality of your focus ring (since many of us are using AutoFocus) into a Clear Image Zoom ring, so you can zoom smoothly while recording. Could even give it a power-zoom mode where you twist to zoom in/out at various speeds.
Connectivity / Net features
Realtime bluetooth video feed and camera control over for all settings over Smartphone
This already exists to a large degree on the GoPro. The live video feed and changing of camera settings works well although they can't output the video feed while recording.
What are your predictions?
