Frequently asked questions about Authoring

Supported media formats

The below media types and formats are supported.

Media Type



.mp3 only (limited to 10MB)


.svg, .jpeg, .png


.mp4 only (limited to 30MB)

Could Not Upload

If you are trying to upload an audio file (.mp3) and get an error message "Could Not Upload", it is possible that your file is labelled .mp3 but is not a true .mp3 file.

Files with an incorrect mime type (file extension) can pose a security risk and hence we have a strict protocol to return an error if it is not a true mp3.

When uploading audio files, please ensure that the correct media type is applied to the file. Where .mp3 file extensions are returning the error encountered, we recommend making use of free online conversion tools to quickly assign the correct media type.

"Story Completed" message showing although story not complete

If the "Story Completed" message is showing before the end of a story, you may have added a split page (linked pages) on the last page of a story.

To avoid this issue, remove the split page if it is the last page of a chapter.

Video not playing audio

All videos need to be saved in .mp4 format.

The codec must be set to ACC - not .mp3 (2.0 Channel).

If you don't have video editing software and need to change your video's codec, please download and make use of Handbrake.

Background colours

When you choose to edit a template background colour, you are presented with a colour palette called "FALKOR COLOURS". These colours work well on retina screens and are designed to look good across devices.

When using a template that allows you to upload an image, Falkor will show "RECOMMENDED COLOURS" colours that go well with your image.

Can I create a custom template?

In order to simplify authoring, we have done all of the design and layout work for you.

This means you have an ever-growing template library to work with, but you might not be able to place things exactly where you want them. Using Falkor's tried and tested templates ensures that your content will always look good on multiple devices and screen sizes.

How do I order stories?

The best way to order stories is by creating custom categories. You can then publish stories to different categories that will be visible on the app.

You can also order your stories and decide in which order they should be displayed.

How do I delete a Falkor story?

Because stories may have been previously published by users, they can not be deleted.

If you are no longer using a story slot or want to re-use a story slot, you can delete all of the content (simply delete whole chapters) and create a new story.

An edited story will overwrite the previous version of the story.

Video not loading or loading slowly

If your user audience is likely to be using lower-end devices or non-premium smartphones, it is suggested to use low-quality videos. Consider limiting your stories to 25MB - 50MB. For more information on what could be causing slow video or story load times, have a look here.

Recommended Story Size

It is recommended to limit each chapter to 50 pages.

Falkor imposes a limit of 100MB per story. This is to minimise loading times & capacity requirements for the end-user.

Consider your audience. If bandwidth and connectivity are an issue, always attempt to minimise your story size.

How can I unpublish a Falkor story?

If you have published a Falkor story and want to remove it from your app, you can use the story options and select "Remove Listing".

Remove a story listing

What is the Settings / Manifest?

Story Settings / Manifest allows you to set the story type, story details,. scoring options, story theme and main colour.

Where is the Settings / Manifest?

When you create a new story, the Settings / Manifest window will open.

To access it again later, open a story and select Story from the menu, then select Settings / Manifest from the dropdown.

How can I delete a Story?

It is not possible to delete a story, but you can re-use the story slot. If you are not using a story slot, we recommend deleting all the chapters and pages, removing the story listing & asset details and renaming the story to, e.g. "Empty Story". This will allow you to "clean up" any stories that are not in use and easily identify them.
