One real walkthrough,
followed start to finish
An agent filmed a 1 bed, 1 bath apartment in Boston in one handheld take. Here is what CastMyListing kept, wrote, heard back and checked. Every number on this page comes from that shoot.
Every second is measured before a word is written
Each shot is scored for shake, blur and speed, and every room is labeled. Below is the 1:04 clip in the order it was filmed. Each bar is one shot: its width is how long it runs, its height is how steady and sharp it is.
The 8.1 seconds no video used
- The front door swinging open 0:00.0 to 0:00.7, blur 1.00
- Whip pans between rooms 0:40.0 to 0:44.1, shake 0.81, 0.93 and 0.64
- Turning past a door 0:46.6 to 0:47.9, shake 0.85
- A blank wall 0:58.8 to 1:00.8, blur 0.85
A script for each platform, every line heard back
Same footage, same facts, two directors. TikTok opens on a reaction and ends by asking for comments. YouTube walks room by room and ends by asking for a showing. After the voice reads a line, speech recognition listens to it; a line that comes back different is recorded again.

All 20 lines came back word for word, so none had to be recorded again. Bold words are highlighted on screen. How each platform is cut
Every file is checked against its platform
Before the agent saw either video, each file was tested for the things that get a video rejected, muted or skipped.

Then it's your turn
The agent watched both previews for free, could ask for changes in plain words ("start with the kitchen", "mention the parking"), then downloaded each video with its post text. Everything you can change
