YouTube tips

🎬

YouTube re-encodes everything you upload. Compress to reduce upload time, but keep quality at 80%+ so YouTube has good source material.

📐

YouTube recommends 1080p at 16:9 (1920×1080). 4K (3840×2160) is supported but takes much longer to upload and process.

⏱️

Unverified accounts can upload up to 15 minutes. Verified accounts can upload up to 12 hours. File size limit is 256 GB.

💡

H.264 (MP4) is the most efficient format for YouTube uploads. VP9 is also supported but H.264 uploads tend to process faster.
