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
Set a row's source type to File.
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.Set the row's SRT destination and bitrate as usual (video allows up to 50 Mbps).
Tick the row, then click Broadcast Selected Rows to go live.
(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.
Set a row to File and pick an image (
jpg,jpeg,png,tiff,tif,bmp,webp,heif,heic).Choose a Frame Rate — use the lowest available for static signage to save bandwidth and CPU.
Choose a Resolution Mode: Force 1080p, Force 2160p (4K), Native (keep original size), or Crop to 16:9.
If you chose Crop to 16:9, pick Fit (letterbox — whole image visible) or Fill (fill the frame, crop the overflow).
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.
The File Player window
A transport and preview window for a file. It does not broadcast on its own — to go live you still tick the row and click Broadcast Selected Rows.
Open it: on a File row that already has a file, click the small orange screen-with-play-arrow icon at the right of the row.
Use it:
Wait for the preview to connect — "Connecting to preview..." clears once frames arrive, and a codec/resolution badge (e.g.
HEVC 1920x1080 @ 25.00fps) appears bottom-left.Use Play/Pause to start/stop, drag the timeline to scrub, and use Step Back/Forward for frame-accurate positioning.
Press [ and ] to set In and Out points; the selection is shaded, and Go to Start / Go to End snap to them. Click the X to clear them.
Toggle Loop (icon turns blue) for seamless looping, and pick a Speed (0.25x–2x) from the dropdown.
To swap media without leaving the window, click the folder icon in the titlebar and load a different file.
Tips & gotchas
A freshly picked file starts playing immediately, even before you broadcast. Use the inline Pause on the row to hold it.
The File Player window doesn't broadcast — it's for preview and transport only. Tick the row and click Broadcast Selected Rows to go live.
Bitrate caps: video rows go up to 50 Mbps, image rows up to 5 Mbps.
Files on external drives or system folders may ask for OS permission the first time you open them.
