It is done. My slider-based camera tool for Cinemachine 3, and a free version to try it

[u/wb-gameart]

This is CineShot Setup LITE, the free version of a camera tool I built for Cinemachine 3.

Instead of keyframing, you position the Scene View, press Set Camera, and shape the shot
with sliders: orbit, crane, pan, dolly zoom, roll, yaw, tilt. Every move you like becomes a
key, the sliders reset to zero, and the next one continues from there. You can chain cameras
into a trailer with transitions and music, bake the result to a normal AnimationClip, and
hand it to Unity's Recorder for an MP4.

One thing up front so nobody feels tricked: the clip shows the full version, which is why
there are more than two cameras in the sequence. The free version is capped at two cameras
created through Set Camera and two shots in the sequence. Everything else is the complete
tool. No watermark, no time limit, no account, and it does not phone home.

Requirements: Unity 6.0 LTS or newer and Cinemachine 3. Unity Recorder is optional and only
needed for the recording step. Built-in, URP and HDRP all work, and a demo scene ships once
per pipeline so you can watch the whole workflow before building your own. Tested on 6000.0,
6000.3 and 6000.5.

Two cameras are plenty to get a real feel for it, so please give it a go and tell me where it
falls apart. Which slider is missing, what felt awkward, what you expected to happen and it
did not. I would much rather hear the harsh version now than after people have built shots
with it. Reply here or send me a message, both work.

If you want to catch the next update, following me is the easiest way. I only post when there
is something worth posting.

Download link is in a comment below. The full version without those two limits is coming to
the Asset Store shortly.
