Questions

Why does TikTok make my video blurry?

TikTok recompresses every upload. A clean high-bitrate H.264 file in a standard MP4 container survives that step with fewer artifacts.

Is my video uploaded anywhere?

No. Processing happens inside your browser, so the file stays on your device.

Why is 4K slow on my phone?

The video is processed by your own device. For long 4K clips use a computer, or pick 1080p.
