FlashBoards imports common image, video and audio files into a board. A file can sit on the board and still not fit a model's input, so when a model card shows stricter rules, follow those.

[Video: Images, video and audio all drop straight onto the board](https://media.yaroflasher.com/docs/media/supported-formats-drop-files.h264.cf7af995.mp4)

## Import formats

Drag files onto the board, paste them, or use **Import Media** in the Media Browser. See [Import media](https://flashboards.yaroflasher.com/docs/media/import-media.md).

| Type          | Formats                                                                                      |
| ------------- | -------------------------------------------------------------------------------------------- |
| Image         | PNG, JPG/JPEG, WebP, GIF, SVG, BMP, TIFF (only in browsers that can open it, such as Safari) |
| Video         | MP4, MOV, AVI, WebM, M4V                                                                     |
| Audio         | WAV, MP3, M4A, AAC, FLAC, OGG, AIF, AIFF                                                     |
| Board archive | `.refboard`, compatible `.zip` (use **Import Board**)                                        |

HEIC, AVIF and MKV aren't accepted. Some MOV files (often from iPhones) won't play in the browser; convert them to MP4 (H.264) and import again. There's no size limit at import.

## Model inputs

Each input slot takes one kind of media: image slots take images, video slots take video, audio slots take audio. Multi-reference slots take several images, and video or audio where the model allows it.

Inputs can be up to about 100 MB. Common reasons a model rejects a file are too many pixels, the wrong aspect ratio or frame rate, a video that's too long, or no clear subject. Recompress or trim with [Media tools](https://flashboards.yaroflasher.com/docs/media/media-tools.md) when needed.

Video models that need reference clips at a constant 24 fps accept ordinary constant-24-fps exports. Variable frame rate clips are rejected; convert them with **Convert** → **24 FPS** in [Media tools](https://flashboards.yaroflasher.com/docs/media/media-tools.md).

## AI action limits in the app

These apply when you use the actions from a board. The API has its own limits; see [Public API](https://flashboards.yaroflasher.com/docs/integrations/api.md).

| Action                     | Formats                    | Limit                                           |
| -------------------------- | -------------------------- | ----------------------------------------------- |
| **Describe** image         | JPG, PNG, WebP             | Resized automatically                           |
| **Describe** video         | MP4, MOV, WebM             | Short clips; trim long videos first             |
| **Transcript**             | Audio, or video with sound | Up to 3 minutes and 32 MB. Not on shared boards |
| Image safe transform       | JPG, PNG, WebP             | About 15 MB                                     |
| Video safe transform       | MP4, MOV, WebM             | About 100 MB                                    |
| Shared board preview image | JPG, PNG, WebP, GIF        | Common web image sizes                          |
