Importing a video
Video Reference keeps a video file synchronized to the audio for confirmation monitoring. This is useful when your show includes video playback and you want to see what the audience sees on screen while LTCast runs timecode.
Importing a file
Load a song first: the import needs audio to align against, so File → Import Video is greyed out until a song is loaded. Then choose it, or click the import button in the Video Audio row under the waveform. When the song has no video yet, that row is a dashed strip with an Import Video button in it. A file picker opens; it lists .mp4, .mov, .mkv, .avi, .webm, .mxf and .ts files.
The video appears in the Video Reference panel straight away. In the background LTCast reads the video's audio (Extracting audio...) and shows it as a green Video Audio lane under the music waveform. It compares that audio with the loaded song to work out how the two line up.
Auto-alignment
After import, LTCast aligns the video to the audio by matching the two waveforms. In most cases no further adjustment is needed; fine-tuning is available with the frame nudge buttons (see Frame nudge) or by dragging the lane (see Aligning video to audio).
Per-song memory
The video file is remembered per-song. When you switch to a different song in the setlist, LTCast automatically loads the video assigned to that song and clears the preview if the new song has no assignment. See Per-song video memory for details.
Sound and output
The preview is silent by default and only follows the playhead: it never drives the clock, and nothing it does reaches LTC, MTC or any other output. In the Video Audio row three buttons choose what you hear:
- Mute — the default; the video is silent.
- Both — the video's own sound plays in the preview alongside the music, so you can compare the two. A volume slider appears.
- Solo — only the video's sound is heard: the music output is silenced until you leave Solo. LTC and the other timecode outputs are not affected.
The mode goes back to Mute every time you switch songs, so Solo cannot carry its silenced music over into the next song. The video's sound comes from the preview in the main window, so you hear it only while that preview is shown (see Hide / show preview); the pop-out window is always silent.
