Dial timing fast, then check the look. Preview with Solid shading at 50% to set speeds, then switch to Material for a look check.
Always ease. A few frames of ease-in and ease-out make a ramp feel filmed rather than switched. A chunk shorter than its ease-in plus ease-out never reaches full speed, and TimeShift warns you.
Turn on Motion Blur. Scale Motion Blur Shutter is on by default, so the shutter follows the local speed: blur shrinks as time slows, the way a real high-speed camera behaves, and grows back as speed returns. Without it, slowed frames carry normal-speed blur and smear.
Read the estimate before you render. Output length grows with slowdown: 20 scene frames at 0.1 become 200 rendered frames, and render time grows with them.
One output folder per shot. TimeShift never deletes files, so a shorter re-render into the same folder leaves the old extra frames behind. Clear the folder or use a new one.
Export the frame map for sound and editing. It records which scene time every output frame shows, so you can sync audio or match the retimed sequence back to the original.
Bake once, then iterate freely. Speeds, eases and chunks can change without rebaking; only a changed simulation needs a new bake.
