Looping video for a sales center screen: file format, portrait or landscape TVs, USB playback and playlists

The sales gallery has a big screen by the model and a USB stick with the project film on it, and on opening day the video plays sideways, shows a control bar every time it restarts, or doesn't play at all. A film that looks right on a phone needs a few changes before it runs all day on a TV. This guide covers the file format that plays almost everywhere, resolution and rotation for portrait and landscape screens, the USB playback quirks that catch people out, loop length and silent design, and how to turn several 30-second films into one playlist.

Key takeaways

• An H.264 MP4 with AAC audio, or no audio, at the screen's native resolution is the safest file for a sales center loop; Samsung's 2025 TVs and BrightSign players both list H.264 and MP4 support.
• A consumer TV mounted in portrait still thinks it's landscape, so a vertical film has to be rotated 90 degrees into a 1920 × 1080 file before it goes on the stick.
• Format the USB stick as exFAT, plug it straight into the TV, and keep only the video files on it; Samsung's TVs read FAT, exFAT and NTFS and only mass-storage devices.
• Design the loop to work silently, since staff hear it all day; choose a film with no soundtrack or strip the audio track.
• Joining several 30-second films into one file with FFmpeg's concat demuxer gives a two- or three-minute loop with fewer restarts and no gaps.

What file works best for a looping sales center video?

Use an H.264 MP4, with AAC audio or no audio, made at the screen's native resolution and in the orientation the screen is mounted: 1080 × 1920 for a portrait signage display that rotates content itself, and a rotated 1920 × 1080 file for a consumer TV hung on its side. Design it to make sense without sound, and test it on the actual screen, from the actual USB stick, for a full day before the sales center opens.

H.264 in an MP4 container is the conservative choice because it's what nearly every device decodes. As of October 2026, Samsung's 2025 TV specifications list MP4 among the supported containers and H.264 up to 1920 × 1080 at 60 frames per second even on the basic Full HD model, with "Level 4.2 supported" for Full HD files, and AAC among the audio codecs (Samsung 2025 TV video specifications). BrightSign's documentation lists H.264 and .MP4 among the formats its players handle (BrightSign video formats and codecs). Newer codecs such as HEVC or AV1 save space, but space isn't the problem on a USB stick; compatibility is.

Resolution and orientation by screen

Most sales centers have one of four setups. Pick the row that matches yours.

Signage players handle portrait differently by model. BrightSign notes that "portrait-orientation video (1080x1920, 2160x3840, etc.) support has specific limitations by player model," so read your player's page before deciding between a native vertical file and a pre-rotated one.

For a landscape TV, you don't have to settle for black bars. Put the vertical film in the center of a 1920 × 1080 frame in an editor, and use the side panels for the project name, a QR code to the website and the artist's-impression line. That also gives you a place for any permit or registration number your market requires on audiovisual ads; the off-plan launch film guide lists those rules for several markets.

Rotating a vertical film for a portrait-mounted TV

Burn the rotation into the pixels rather than relying on a rotation flag in the file, which some players ignore. With FFmpeg:

ffmpeg -i film.mp4 -vf "transpose=1" -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a copy film-rotated.mp4

transpose=1 turns the picture 90 degrees clockwise and produces a 1920 × 1080 file. If it plays upside down on your screen, the TV was turned the other way; use transpose=2 instead.

USB playback quirks and how to avoid them

USB playback is the cheapest setup and the most fragile. Most problems come from the stick or the file, not the TV.

The stick. Samsung's TV guide says "the TV supports the FAT, exFAT, and NTFS file systems," supports "Mass Storage Class (MSC) USB devices only," which "must be connected directly to the USB port," and may not recognize some devices when several are connected (Samsung TV user guide, as of October 2026). Format the stick as exFAT, which both Macs and Windows PCs can write, plug it in without a hub, and keep only the video files on it. A Mac copying to a non-Mac drive can leave hidden files beginning with "._" next to each video; some TVs list them as files they can't play, so remove them, for example with dot_clean -m in Terminal.

The file. The same guide warns that "certain files, depending on how they are encoded, may not play on the TV," and that 2025 models don't support WMA, WMV or VC1. If a file refuses to play, re-encode it with plain settings:

ffmpeg -i film.mp4 -c:v libx264 -profile:v high -level:v 4.1 -pix_fmt yuv420p -crf 18 -c:a aac -b:a 160k -movflags +faststart film-tv.mp4

This keeps the resolution and frame rate, uses a widely supported H.264 profile and level, and writes standard AAC audio. Add -an instead of the audio options to make a silent file.

Repeat mode. TV media players differ in where they hide "repeat" and whether it repeats one file or the whole folder. Samsung's guide page doesn't describe it, so find it on your model before opening day. Some TVs also flash the file name or a control bar each time a file restarts. A longer file restarts less often, which is one reason to join short films into one.

Power. Some consumer TVs have energy-saving or auto-off timers that switch the screen off after a period with no remote input. Check the eco settings, and decide who switches the screen on each morning. For a sales center that runs for a year, a commercial display or a dedicated signage player, which boots straight into playback, is worth pricing against the cost of a dark screen.

Loop length and silent design

There's no single right loop length, but three audiences set the limits. A visitor walking past catches a few seconds, a buyer sitting with a consultant sees the screen for much longer, and the staff see it all day, every day. A single 30-second film repeated all day gets old for the people working next to it, so a playlist of three to six films, a loop of roughly 90 seconds to three minutes, usually works better.

Design for no sound. Sales consultants talk to buyers in the same room, and a soundtrack on repeat for eight hours wears on everyone. A film built only from images and motion, without voice-over or on-screen captions, reads fine muted. If your film has music, make a silent copy for the screen and keep the music version for social posts; music for architecture videos covers the social side.

Watch the loop point. If the jump from the last frame back to the first is abrupt, add a short fade to black at both ends in any editor, so each restart feels intentional.

Label it on site. A screen showing an unbuilt project should carry an "artist's impression" line, either in a side panel or on a placard beside the screen. If the film was AI-generated from renderings, that line should say so.

Several 30-second films in one playlist

A playlist lets the screen walk visitors through the project: arrival and exterior, then amenities, then interiors, then the neighborhood. Plan it as a set.

Arch2Video makes each of these from six images of the same project: a 1080 × 1920 vertical H.264 MP4 of about 30 seconds, six connected five-second scenes, with an original soundtrack or none. You can buy several videos at once for USD 15 each as a one-time payment, unused videos stay on the account and don't expire, and you can switch a finished film's soundtrack to none and re-export it without paying again. Each film includes a small cast of fictional adults in at least one scene, and AI motion is an interpretation of your images, so review every film before it goes on the screen. Generation usually takes an hour or more; there's no free trial.

You can let the TV play the folder in order, but folder playback often leaves a short gap or overlay between files. Joining the films into one file avoids that. FFmpeg's concat demuxer reads a text file that lists the files in order:

file 'film-1.mp4'
file 'film-2.mp4'
file 'film-3.mp4'
file 'film-4.mp4'

ffmpeg -f concat -safe 0 -i list.txt -c copy playlist.mp4

FFmpeg's documentation says "all files must have the same streams (same codecs, same time base, etc.)" for this to work (FFmpeg formats documentation). Films exported by the same tool with the same settings usually match, so -c copy joins them without re-encoding. If the joined file stutters at the joins, run the re-encode command above on the result. -safe 0 lets the list use full paths or file names with spaces. Then rotate the joined file if the screen is portrait-mounted.

The same films can run on the website: a website hero video covers trimming a film into a light, looping background clip.

Test before opening day

Run the real file on the real screen from the real stick, and leave it running.

1. Play the file from the stick on the actual TV, not a laptop.
2. Let it loop for a full working day and check it at the end.
3. Watch from where visitors stand; check that people, text and the plan read at that distance.
4. Watch three restarts in a row for overlays, gaps or a black flash.
5. Pull the power, switch it back on and time how long it takes staff to get the loop running again. Write the steps on a card behind the screen.
6. Check the TV's picture mode. Store or "vivid" modes can oversaturate renderings; a standard or movie mode is usually closer to what the visualizer intended.

Frequently asked questions

Why won't my video play from a USB stick on the TV?

Usually the stick or the encoding. Check that the stick is formatted FAT, exFAT or NTFS and plugged directly into the TV rather than through a hub, then re-encode the file as a plain H.264 MP4 with AAC audio using the FFmpeg command above. Remove hidden "._" files a Mac may have added. If it still won't play, check the TV model's video specifications for resolution and frame-rate limits.

Can I play a vertical video on a landscape TV?

Yes, but on its own it shows as a narrow strip with wide black bars on both sides. Either mount the TV in portrait and rotate the file, or place the vertical film in the center of a 1920 × 1080 frame with designed side panels for the project name, a QR code and the artist's-impression line.

Should a sales center video have sound?

Usually not. Staff and buyers talk in the same room, and a soundtrack on repeat all day wears on the people working there. Make a silent version for the screen, design it to read without sound, and keep the music version for social media and the website.

How long should a sales center loop be?

Long enough that it doesn't feel repetitive to staff, short enough that a passing visitor sees something complete. A playlist of three to six 30-second films, roughly 90 seconds to three minutes, works for most galleries. How long an architecture video should be covers lengths for other uses.
