How to check a Reel before posting.

1.Watch the first three seconds twice: sound off, then sound on

With the sound off, does the picture change in the first three seconds: a cut, a camera move, a zoom, something moving? With the sound on, is there a voice, a beat or a sound in the first second, at full level, not faded in? If the Reel is face-led, is the face there in the first second?

target something happens from the first second; a cut, movement or a new look within 3 s; the first face in the first second

2.Count the seconds before the first word

For a talking Reel or a voice-over, note the second the first word lands. Silence before it reads as a slow start, and most of the lead-ins creators keep (a logo sting, a breath, a walk into frame) push it past two seconds. A music-led Reel with no talking gets the same check on the music: it should start at once.

3.Look for dead air and still stretches

Dead air is a second or more that is both silent and still. A still stretch is the picture not changing for more than three seconds while something else carries on. Both are where viewers leave. Scrub the middle of the Reel and note where each happens; a cut, a punch-in or b-roll fixes a still stretch, a music bed fixes a quiet one.

target no dead air over 1 s; nothing still for more than 3 s

4.Check that something new keeps happening

Every few seconds a viewer needs a reason to stay: a cut, a new line, a sound hit, a face arriving, a change of shot. Count them in a ten-second stretch from the middle of the Reel. If a stretch has none, that is where it sags.

target 2 or more new moments per 10 s, in every part of the Reel

5.Listen for the level

Play it on the phone, not the headphones. Platforms even out loudness, so a quiet mix does not get louder on the feed, it gets quieter relative to everything around it. The opening should be as loud as the rest, with no slow fade-in.

target -26 LUFS or louder in the first 3 s

6.Watch the ending on its own

Play the last three seconds. Does it land on something: the payoff, the line, a loop back to the start? Or does it trail off into a silent tail? The ending is what people remember and what decides a replay.

target the ending as lively as the rest; no dead end

Can a tool tell me whether my Reel will go viral before I post it?

No. Views depend on the topic, the timing, the audience and the platform's own choices after you post, and none of that is in the file. What you can check before posting is the craft of the cut: whether it starts at once, when the first word lands, whether there is dead air or a long still stretch, how loud it plays, and whether it ends on something. Those are measurable, and they are the part you control.

What should I check in a Reel before posting?

Six things: the first three seconds (something happens, the picture changes, a face if there is one), the first word (under a second for a talking Reel), dead air (none over a second), still stretches (nothing still for more than three seconds), loudness (-26 LUFS or louder, no slow fade-in) and the ending (it lands on something rather than trailing off).

Does NeuroVidz predict views or where viewers will drop off?

No. NeuroVidz measures how a clip is built and marks the places viewers usually leave, at the second they happen: a slow opening, a late first word, dead air, a long still stretch, a sag with nothing new, a limp ending. It does not forecast views, reach or a retention curve. Instagram's own insights show real retention after you post.
