The FILE source broadcasts a local video file or still image as if it were a live camera. Pick a file on a source row and it plays straight into your SRT output. A dedicated File Player window adds full transport control — play/pause/stop, scrubbing, frame-stepping, in/out points, speed and looping — with a live preview.

[!IMPORTANT]

Turn on FILE sources first: click the gear icon in the footer, open Beta Features, tick FILE Source Type, and close settings. "File" is now a source type on any row.

Broadcast a video file

1. Set a row's source type to File.
2. Click the row's source control — the file picker opens. Pick a video (mp4, mov, mkv, avi, mts, mxf, m4v, mpg, mpeg, wmv, flv, webm). It starts playing immediately.
3. Set the row's SRT destination and bitrate as usual (video allows up to 50 Mbps).
4. Tick the row, then click Broadcast Selected Rows to go live.
5. (Optional) Click the orange File Player icon at the right of the row for scrub/loop/speed control — see The File Player window.

Broadcast a still image

A still image is sent as a continuous video stream.

1. Set a row to File and pick an image (jpg, jpeg, png, tiff, tif, bmp, webp, heif, heic).
2. Choose a Frame Rate — use the lowest available for static signage to save bandwidth and CPU.
3. Choose a Resolution Mode: Force 1080p, Force 2160p (4K), Native (keep original size), or Crop to 16:9.
4. If you chose Crop to 16:9, pick Fit (letterbox — whole image visible) or Fill (fill the frame, crop the overflow).
5. Set the SRT destination (image rows cap at 5 Mbps), tick the row, and click Broadcast Selected Rows.

[!NOTE]

A higher image frame rate raises CPU and bandwidth even though the picture is static. For unchanging signage, pick the lowest rate.
