Często Zadawane Pytania
What is picture-in-picture good for?
Reaction videos (your webcam over gameplay or a match), tutorials (your face over a screen recording), and commentary clips — anywhere you want a second video in a corner.
Which video should I upload first?
Upload the main / background video first, then add the smaller overlay video (for example your webcam). The overlay sits in the corner you choose.
Whose audio is kept?
The main video keeps its audio. If you need to mix both, record commentary into one of the clips first, or combine audio in a dedicated editor.
Does anything upload to a server?
No — both clips are processed locally with FFmpeg WebAssembly. Nothing leaves your browser.
