Listing video length and format: where the seconds come from

Most advice about listing-video length is somebody's preference dressed up as a rule. This is the other thing: the arithmetic. If you understand where the seconds come from, you can decide the length yourself and you will know when a tool is promising you something it cannot deliver.

Start with the three files, not the one video

A listing video is not one asset. It is the same footage cut three ways, because the three places it goes crop differently:

Cut	Ratio	Pixels	Where it goes
Reel	9:16	1080 × 1920	Instagram Reels, TikTok, YouTube Shorts, Facebook Reels
Feed	1:1	1080 × 1080	The Instagram and Facebook grid, and most email clients
Listing page	16:9	1920 × 1080	The MLS media slot, YouTube, your website, an embed

All three are 1080p at 24 frames per second. The reason to render all three from one set of footage rather than shoot three times is not effort, it is consistency: crop a 16:9 frame down to 9:16 in an app afterwards and you will lose whichever third of the room the app decides to lose, usually the ceiling you were trying to show.

If you only ever export one, export the 9:16. It is the only ratio that fills a phone screen, and a listing video is watched on a phone.

Where the seconds come from

Here is the constraint nobody advertises. Image-to-video models return a fixed, short piece of footage per generation. In our pipeline one generation returns 5 seconds, and that is a ceiling, not a setting — you cannot ask for a longer one, you can only ask for more of them.

So a listing video's length is:

segments × seconds per segment − crossfades × (segments − 1)

At our cap of 6 segments, with the default 0.5-second crossfade, that is 27.5 seconds. Drop to hard cuts and you recover the crossfade time, giving an absolute ceiling of 30 seconds. Below 3 segments a video stops reading as a tour and starts reading as a slideshow of three pictures, so that is the floor.

This is why our format list offers a 15-second reel and a 30-second reel and why the 60-second tour reports itself unavailable rather than shipping short. A format with a duration in its name has to hit that duration exactly or it is not that format; the planner solves for per-segment length, spends its crossfade budget last, and refuses before it ships a 30-second file labelled "60-second tour".

How long should yours be?

Two honest answers, and one thing we will not tell you.

The thing we will not tell you is an optimal length in seconds backed by a percentage. We have not measured watch-through on listing videos, nobody has given us a dataset we can audit, and a number pulled from a marketing blog is not evidence just because it has a decimal point in it. If you see a specific figure quoted with no primary source, treat it the way you would treat a comp with no address.

The first honest answer is: match the slot. A vertical reel competes with a scrolling thumb, so front-load — the strongest exterior or the best room first, not the drive-up approach. A listing-page embed is watched by someone who has already decided to look at this house, so it can afford to be slower and more complete.

The second is: match the photo count. One segment per photo means six good photos make a better video than twelve mediocre ones, because the twelve get cut to six anyway and the algorithm that picks is you.

The six photos, in order

If you are giving a tool six slots, this order gives it the best chance:

1. Front exterior — establishes the house. Shoot it with the sun behind you.
2. The best room — not the entry. Whatever room sold you on the listing.
3. Kitchen — the room most buyers scroll to first.
4. Primary bedroom
5. The differentiator — the view, the shop, the finished basement, the thing this house has that the one down the street does not.
6. Back yard or outdoor space — ends the video outdoors, which reads as "come see it".

Skip the bathroom close-ups, the laundry, and the garage interior in a short cut. They are necessary in a photo set and they are dead air in a 30-second reel.

Frame edges: what gets eaten

Every vertical platform overlays its own furniture on the frame — captions, the profile row, the share and comment column. Anything you care about should sit inside the middle of the frame, not the top or bottom eighth. This is the practical reason not to burn text into the bottom of a reel and the reason a listing video should not depend on a price banner to make sense.

It is also why we typeset on-screen text ourselves rather than asking an image model to draw it. A model asked to render "$1,250,000" will confidently produce "$1,25O,00O". A price that is wrong by one glyph, on a graphic about a real address, is not a cosmetic bug.

General information, not legal advice. Advertising law, MLS rules and broker policy vary by market and change often. Confirm anything specific with your broker, your MLS, and — where money or rights are at stake — your own attorney.

ReeltyPro turns the listing photos you already have into a 6-segment video in 16:9, 9:16 and 1:1, and tells you segment by segment which parts are generated motion and which are a camera move over your own photograph.
