What should I record, and how long can it be?
Short answer: Record your screen while you talk through it, the way you would show a colleague. Audio quality barely matters, because the narration is replaced. MP4, MOV, MKV and WebM all work.
What makes a good recording
- Talk while you click. VideoPolisher writes the new script from what you say and what is on screen, so say what you are doing, even roughly.
- Do not worry about ums, pauses, restarts or background noise. Your voice is replaced and dead time is trimmed.
- Record at the resolution you work in. The video is brought to 1080p for you.
- Show things in the order you want them explained. The narration follows the order of what happens on screen.
Files
Video: MP4, MOV, MKV or WebM. For a podcast you can also upload audio (MP3, WAV, M4A), paste text, or give a link to an article.
Length
On the Free plan a recording can be up to 3 minutes. Paid plans have no fixed limit; the price follows the length, and the estimate is shown before every run.
