Why Pre-Compressing Matters
YouTube Shorts videos must be vertical (9:16 or square 1:1) and under 60 seconds (or up to 3 minutes for expanded shorts). When creators upload raw camera files, YouTube takes minutes processing the stream and can downscale quality to 720p. Pre-optimizing with VideoReduce guarantees high-priority 1080p 60fps encoding with minimal processing wait time.

Frequently Asked Questions
How do I ensure YouTube processes my Short in 1080p60?
Export with standard 1080x1920 H.264 MP4 with AAC audio. VideoReduce embeds correct aspect ratios and stream tags that YouTube recognizes immediately.
Why is YouTube taking so long to process my Short?
Bloated 4K uploads force YouTube to re-encode heavy streams. Pre-compressing to 1080p makes YouTube processing finish in seconds.
What is the maximum aspect ratio for YouTube Shorts?
Vertical 9:16 (1080x1920) is recommended, but 1:1 square is also recognized as a Short if under 60 seconds.
Can I compress multi-gigabyte video projects for Shorts?
Yes! VideoReduce handles files of any size directly in your browser's local memory.
