It depends on your goal and audience.
- Short videos (under 5–10 mins) work well for attention-grabbing, mobile viewers, and building quick engagement. Great for starting out or summarizing big topics.
- Long videos (10–30+ mins) are better for deep storytelling, watch time, and monetization. YouTube rewards longer retention.
Tip: Start with short documentaries to build interest, then mix in longer, detailed ones as your channel grows.
Consistency + quality = success. Choose what you can produce best!
