Choosing Your Clip Length
One to five seconds sounds like a small range. In practice it is the difference between a film that reads as the passage of time and one that reads as a series of scenes, and it is the setting people most often get wrong on the first attempt.
One second is a rhythm
At one second nothing has time to be a scene. What you get instead is cadence: a pulse of images where the meaning comes from accumulation rather than from any individual day. Faces change, seasons turn, and no single clip carries weight.
This is the right choice for long periods: a year, a school year, a first year. It is the wrong choice for anything where individual moments need to land.
Three to five seconds is a scene
At three seconds a day becomes legible on its own: you can hear a full sentence, see a complete rep, register what someone is actually doing. The film stops being a pulse and starts being a sequence of small scenes.
The cost is runtime, and it compounds hard. Three seconds across a year is over fifteen minutes. Reserve longer clips for shorter spans: a trip, a training block, or a wedding week.
Two is the useful compromise
Two seconds keeps a year under about ten minutes while giving each day enough room that slow subjects still read. It is the length worth choosing for babies, animals, and anything else that does not perform on cue.
It is also where the free version of Dayjavu stops, which makes it a genuinely useful place to test the format before deciding.
Consistency beats the number
Whatever you pick, apply it to every day. A uniform length is what makes the result feel composed rather than assembled, and it is what lets the eye stop tracking duration and start watching the content.
Varying clip length per day sounds like added expression and reads as inconsistency.
Quick guidance
- A year or longer. One second.
- Babies, animals, slow subjects. Two seconds.
- A trip, a block, a week. Three to five seconds.
- Whatever you choose, keep it the same throughout.
FAQ
- Can I change it after building the compilation?
- Yes. It is a setting on the compilation, so you can change it and re-export from the same clips.
- Can different days have different lengths?
- No, and that is deliberate. The uniform length is what gives the format its rhythm.
- Which lengths are free?
- One and two seconds. Three, four and five unlock with the one-time purchase.
