How short or long should my WebM be for a good WebP?
+
Animated WebP is best for clips under 10 seconds. Longer than that and the file balloons (GIF is essentially uncompressed-per-frame); for longer animations target WebP = WebP or APNG, both of which compress similarly to modern video codecs and stay reasonably sized.
For animated GIF: 2-8 MB at 480p depending on motion complexity. For animated WebP: 200 KB to 1 MB at the same resolution and quality — animated WebP is 5-10× more efficient than GIF for the same visual result.
Ńtí WebP ní àwọn ìpele fèrèsé tí wọ́n jẹ́ bí WebM?
Yes — the loop-count option controls whether the WebP loops infinitely (default), plays N times, or plays once and stops. Loop info is stored in the WebP container metadata and respected by every modern viewer (browsers, Discord, Slack, Twitter).

Two common causes: frame-rate downsampling (15 fps WebP GIF from a 30 fps WebM source — fix with the frame-rate option) and palette quantization on GIF (only 256 colours, so smooth gradients band — switch the WebP target to WebP or APNG for full colour fidelity).
Can I crop or resize the WebM before making the WebP?

Animated WebP encoding is CPU-bound and slower than a typical video re-encode — expect about 1× source duration for GIF (palette generation is the bottleneck) and 0.5× for animated WebP. A 10-second clip finishes in about 10-15 seconds.
Does the WebP preserve transparency from the WebM?
+
Animated GIF supports single-colour transparency only (a binary mask, one transparent index per frame). Animated WebP and APNG support full 8-bit alpha. WebM sources that have no alpha channel — most camera footage and most screen captures — produce fully-opaque WebP regardless of which target format you pick.
