Frequently Asked Questions
How do I upload videos longer than 15 minutes?
Verify your account at youtube.com/verify. You'll need to provide a phone number for verification. Once verified, you can upload videos up to 12 hours (or 256 GB, whichever comes first). Verification also unlocks custom thumbnails and other features.
Why does my 4K video only show 1080p?
YouTube processes higher resolutions gradually. After upload, SD (360p/480p) appears first, then 720p, 1080p, and finally 4K. Processing time depends on video length: 4K can take 4-8 hours. Check back later - the 4K option will appear once processing completes.
What's the maximum file size I can upload?
256 GB or 12 hours, whichever comes first. This limit applies to all accounts (verified and unverified). For perspective, a 1-hour 4K video at recommended bitrate is ~16GB, so most creators never hit this limit. For very long videos, consider splitting into parts.
Should I upload in 4K if most viewers watch in 1080p?
Yes, for several reasons: 1) Future-proofs your content as 4K adoption grows. 2) YouTube's compression is better on higher-res uploads. 3) Even 1080p playback looks better from 4K source. 4) Viewers with 4K displays get better experience. Downside: Larger file sizes and longer upload/processing times.
Does YouTube support 8K video?
Yes, YouTube supports up to 8K (7680×4320) resolution. However, very few viewers have 8K displays, processing takes 12+ hours, and file sizes are massive (80-240 Mbps bitrate). For most creators, 4K is the sweet spot. Upload 8K only if you have 8K source footage and want maximum future-proofing.
