For healthy watch time (less viewer abandonment) you should:
- Cut the most uninteresting and/or slow parts out.
- Keep the high energy, entertaining, and/or important parts to the point of the video in.
For building your brand and engaging viewers to turn them into fans:
- Develop your own unique way of doing things and get comfortable with it.
- If you make high energy videos, keep up that pace in other videos.
- If you add effects when you make cuts, make it entertaining and do it consistently.
For generally making content that's good for viewing:
- Don't ignore your audio, take time to fine tune volume adjustments and eliminate distracting background noises when possible.
- Try to at least produce 1080p quality content whenever possible. Higher quality videos typically show up higher in search results.
- Have fun, enjoy what you're doing, and allow viewers to get to know you!
