Motion, Sound and Music

Motion first: what a keyframe stores, why easing fixes most bad animation, and how timing, anticipation and overshoot give a logo weight. Then lower-thirds, Lottie handover, green-screen keying and exporting video that is not 40MB. Then sound: recording a voice in an untreated room, compression explained properly, EQ in three moves, music licensing and Content ID, and the consent rules for a cloned voice.

1. 1Nothing in the world starts at full speed9 minEase-out for anything arriving or responding, ease-in for anything leaving, and linear only for motion that never starts or stops.
2. 2Motion blur will not fix a floaty logo9 minWeight is uneven distance-per-frame plus a small anticipation and settle; effects added afterwards cannot supply it.
3. 3Why your lower-third looks like a template10 minAnimation time is not reading time — budget two and a half to three seconds of still text first, then add the entrance and exit on top.
4. 4Send the developer a file, not a video9 minIf a developer cannot recolour it, pause it, or place it on a dark background, you exported the wrong format.
5. 5A green screen is fixed on set, not in the edit10 minA keyer builds a matte out of colour information, so anything that degrades colour on set — uneven light, spill, subsampling — cannot be recovered afterwards.
6. 6Your hero video is why the page feels slow10 minFile size follows how much changes between frames, not how many pixels are in one — so bitrate and content, not resolution, are the levers.
7. 7People forgive a soft picture and leave over bad sound10 minDistance and soft furnishings set the ratio of voice to room; the microphone's price is not on that list.
8. 8Compression does not make anything louder11 minA compressor only turns loud parts down; the make-up gain afterwards is what raises everything, including whatever noise sits in the gaps.
9. 9Three boring sounds beat any filter10 minRoom tone plus one or two ordinary foley layers raises perceived quality more than any effect, and a Content ID claim is a match, not a verdict.
10. 10A cloned voice needs a yes you can point to11 minConsent for a voice is scoped — to a project, a set of uses, a period, and whether the model itself is kept — and disclosure to the audience is a separate duty on top of it.
