Supported file types
PublishFi accepts a wide range of video, audio, and image formats so you can work with footage from any camera, phone, screen recorder, or editing tool. This article lists every supported format and explains a couple of behaviors that affect how your files arrive in your project.
Video
| Format | Extension |
|--------|-----------|
| MP4 | .mp4 |
| WebM | .webm |
| QuickTime | .mov |
MP4 is the most universally compatible format and generally the safest choice for uploading. If you are exporting from another editing tool before bringing footage into PublishFi, H.264-encoded MP4 is a reliable option.
Audio
| Format | Extension |
|--------|-----------|
| MP3 | .mp3 |
| WAV | .wav |
| OGG | .ogg |
| M4A | .m4a |
Audio files can be used as standalone source material — useful if you are turning a podcast recording into a visual clip or audiogram — or added directly to the timeline as a background track or voiceover.
Images
| Format | Extension |
|--------|-----------|
| JPEG | .jpg, .jpeg |
| PNG | .png |
| GIF | .gif |
| WebP | .webp |
Images can be added to your project and placed on the timeline as still frames or as the basis for motion graphic compositions.
Long video imports: the trim dialog
If you upload a video file longer than two minutes, PublishFi will show a trim dialog before the file is added to your project. This is intentional, not an error.
The trim dialog lets you select a specific segment of the video to import. Scrub through the footage using the preview, then set a start point and an end point. Only the selected portion is brought into the project.
This behavior keeps your project focused on the content that actually matters and ensures processing stays fast. If you later decide you need a different segment from the same source file, you can import it again and select a different range.
Tip: For best results, upload your source footage at its original resolution and quality. PublishFi handles the encoding when you export — you do not need to compress or downscale your files before uploading.
Importing instead of uploading
If your video is already hosted online, you do not need to download it and re-upload it. PublishFi can import media directly from a URL, which saves time and avoids re-encoding.
Supported sources for URL imports include YouTube, Rumble, Loom, Twitch, Apple Podcasts, direct MP3 links, and RSS feed URLs.
See Importing media from a URL for a step-by-step guide.
