Change Video Speed — maswali yanayoulizwa mara kwa mara

Does the audio pitch change?+

Not by default — 'Keep audio pitch' is on, so a voice stays natural at 1.5× or 0.5×. Untick it for the pitch-shift effect, or tick 'Mute the audio' to drop the sound entirely.

Is my video uploaded?+

No. It's re-recorded from a canvas in your browser.

How fast/slow can it go?+

0.25× (quarter speed) to 4× (four times). The processing time scales with the output length.

What format do I get?+

MP4 or WebM depending on your browser.

Je, mnapakia faili zangu kwenye seva?+

Hapana — kila zana hapa inachakata faili zako kikamilifu kwenye kifaa chako, na hakuna kinachopakiwa kwenye seva. Tofauti pekee ni zana za AI, ambazo hutuma maandishi yaliyotolewa (si faili) kwa Claude ili kufanya kazi yake.

Je, kuna kikomo cha ukubwa wa faili?+

Hatuweki kikomo cha bandia, lakini kwa kuwa uchakataji hufanyika kwenye kivinjari chako, faili kubwa sana (zaidi ya 500MB au kurasa 1,000+) hupunguzwa na kumbukumbu ya kifaa chako, si sisi.
