Supported media & video encoding

A few tips for getting the best quality and fastest availability when adding content.

Video: avoid re-encoding

impressBox automatically recodes uploaded video files so they play reliably on devices. Recoding takes time and can slightly reduce quality. To skip recoding entirely and get the best possible quality with immediate availability, supply video that already matches these parameters:

  • Resolution: 1920×1080

  • Video codec: H.264

  • Audio codec: AC3

Video that already matches these is not recoded — it's available immediately at full quality. Don't worry if these settings mean nothing to you — they're for whoever makes the video. If you commission video from an agency (or use your own editor), just ask them to deliver in this format.

What you can upload

  • Images — static slides such as logos, posters, menus, and notices.

  • Video — motion content. For the best quality and instant availability, match the no-recode specs above (1920×1080, H.264 video, AC3 audio); other formats are recoded automatically.

  • Audio — sound-only or background audio playback.

You can also add content without uploading a file — straight from a URL, YouTube, or Canva (see Add a web page, URL or YouTube video and Importing a Canva design).

Exact accepted file formats and size limits can vary by setup — if a specific file won't upload, check with impressBox.

Reusing similar content efficiently

If you regularly produce many similar items (e.g. price lists, menus, daily notices), don't build each one from scratch:

  • Use an HTML content type / template so only the changing values are updated, or design them in a separate tool and upload as an image.

  • For recurring, data-driven layouts, a parameterized template is the most efficient option (see Templates).

Need a custom layout or an integration with your own data source? Contact your impressBox sales/solutions manager — a tailored template can be built for your exact needs.

Aspect ratio

Match your content to the screen shape (16:9 landscape or 9:16 portrait). If an image doesn't match, impressBox can reshape it with AI — see Content doesn't fit the screen? Fix it with AI outpainting.
