What resolutions are supported?
2160p 4K, 1440p 2K, 1080p FHD, 720p HD, 480p, 360p, or keep original resolution. Each preset applies the recommended YouTube bitrate.
What video formats can I upload?
MP4, AVI, MOV, MKV, WebM, FLV, and WMV files are all supported as input.
How long does optimization take?
Processing time depends on the video length and the encoding speed preset you choose. Faster presets complete quickly but may produce slightly larger files.
