Overlays and visual events

Video Slave supports different kinds of visual overlays to aid your workflow in a variety of ways. This article tells you all about the different kinds of visual overlays and what their intended use case is.

In Video Slave, there are different kinds of visual overlays. The most basic one is the timecode or feet and frames overlay which can be turned on or off through Video Slave's view menu or by using the shortcut Cmd + T. The size, color, background color and font can be chosen through the application's preferences.

But Video Slave also offers more advanced visual events to aid you in different tasks such as composing, editing, conducting or recording. Currently, there are three different kinds of visual events: markers, streamers and flutters. These are explained in the following.



Markers are simple overlays that are supposed to help you identify different sections of the movie. They can be used to mark the start of a new cue while composing, the start or end of a section while conducting. They have a start and end timecode.



Streamer overlays are used to help you find the start of a new cue, the start of a recording take or similar. Traditionally, streamers (also often called 'wipes') are colored bars moving across the screen. They are usually followed by a flashing circle (the "punch") but this can be disabled in the preferences. In Video Slave, there are a variety of settings to customize the visual appearance e.g. the width and height of the streamer bars, the direction of the streamer or the color. Please see this article for a detailed explanation of all available settings.

In Video Slave, streamers can be either time or tempo based. Time based streamers have a selectable length of either 1, 2, 2.67, 3, 3.33 or 5 seconds. The length of tempo based streamers is set in bars. Additionally, you can set the tempo in the unit BPM.

When creating a streamer in Video Slave, you set the timecode of its "hit point". This is where the streamer ends.



Flutter events are basically only a series of punches with a short pause in between. You can set the number of punches to 1 for just a single punch but also to 3, 5 or 7. Flutters can be used as a "visual click" for example to help conductors on tempo changes.
