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.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
