Crucial motion workflow features missing

Hi all,

Figma motion is incredible and is becoming my go-to motion tool. Only a few things are holding it back:

• High-quality export: bitrate control, 4K, .mov with transparency, and correct colour tagging. The current exports are fine for social, but too low quality for more serious uses. 
• Visibility control: let me show or hide a layer at a set time on the timeline, instead of faking it with opacity keyframes.
• Speed graph: Just a really good way of interacting with easings, would be good to have alongside cubic bezier and springs.
• Better resizing: scaling an animated frame or instance should scale its keyframes too. At the moment elements drift out of place, which makes it hard to reuse one animation component across different uses.
• Variant export: export every value of a component property (e.g. 16 headlines × 3 sizes) in one job, without first building an instance for each combination. And bring the API/MCP video export up to the same level as the UI’s multi-layer export. This feature would be really useful for static frames as well.

Thanks, and keep up the great work!
