Viewers watch the performer.
Three studies, of online lessons, YouTube vlogs and TED talks, each found a link between how a speaker came across and how much they were watched.
6.9Mwatching sessions
In online lessons, people kept watching for longer when the speaker talked with enthusiasm.

How it works.
Boldfizz fits between filming and posting. Here is one line, from this video to the next.

1Upload your video
They’ll stay if it’s good.
The review marks the second your voice goes quiet on the last words, and says what to try.
2Practise the line
- Try 1
…if it’s good.
Not yet - Try 2
…if it’s good.
Not yet - Try 3
…if it’s good.
It worked
Say the line again until a try works. Boldfizz tells you whether each one did, before you film anything new.
- Try 1

3Bring your next video
They’ll stay if it’s good.
Reviewed before it’s posted. No note on the ending this time.
Know exactly what to work on.
No score and no grade. A few moments from your video, each one specific enough to fix before you post.
- The exact second
- Not “work on your pacing”. The words, the second, and what your viewer gets there.
- One thing to try
- Something you can say out loud in the next minute, not a lesson to study.
- Whether it worked
- Practise the line and find out if that try landed, before you film again.
- What to keep
- When something already works, Boldfizz says so. Keep doing it.
Voice, eyes and hands.
What Boldfizz looks at in your video, while you talk to the camera. When it can’t tell, it says so.

- 25
- techniques to find them
- 11
Your voice
Pace, pauses, volume, pitch, and whether your tone fits your words. The “um”s too.
Your eyes
When you look to the side of the lens while you talk, and for how long.
Your hands
Whether you gesture while you talk, or your hands stay still, parked or low. It needs you in frame down to your hips.
Before you upload.
- Will Boldfizz get me more views?
- We can’t promise that, and nobody honestly can. The studies on this page find a link between how speakers come across and how much they’re watched, not a guarantee. Boldfizz shows you the moments where you rush, go flat or trail off, and what to try instead.
- I’m just starting out. Is it too early?
- No. You don’t need an audience or a channel, just a video of you talking to the camera. It’s easier to start with good habits than to unlearn them fifty videos in.
- Can’t I just watch my video back?
- You can tell when something feels off, but not what it is or where. Boldfizz names the second, says what happened, and gives you the line to practise before your next post.
- What does it cost?
- Nothing while Boldfizz is in beta. Your first review needs no account. For more videos, make a free account.
