Videos

The easiest way to add local videos to your presentation is to drag and drop them into the Editor. The Visual Tab of the Inspector provides as well a YouTube integration tool.

Note that in the article below, we will call container the available space to place your videos. Depending on the layout, it can be the full slide, a column, or just a cell, in the case of a grid.

Supported Formats

Format	Extension
M4V	.m4v
Moving Picture Expert Group 4	.mp4
Quicktime	.mov

Syntax

The traditional Markdown syntax for images and videos ![](video.mov) is supported but we recommend the simplest Content Blocks Syntax.

You can then simply use the path of the video to display in Presenter. Presenter uses two special “virtual” folders:

• assets for graphics added to the presentation, e.g. /assets/video.mov
• Theme to reference graphics bundled with a theme, e.g. /Theme/video.mov

When using the YouTube integration tool, simply copy/paste the URL from YouTube in the dialog box of Presenter.

The Visuals Tab

The Visuals Tab, available on the right side of the Inspector allows you to:

• See all your graphics (images & videos)
• Drag and drop them into the Editor
• Delete unused ones
• Rename them (don’t forget the extension at the end, e.g, .png)
• Add videos from YouTube

Controlling Local Videos

Local video size and position can be controlled when using the Content Blocks Syntax, using meta-data. You can set them using the dropdown arrow ⬇️ at the end of the video’s path.

Sizes

1. Cover

The video is resized to entirely cover the available space while preserving its aspect ratio. If it does not match the aspect ratio of its container, the video will be clipped.

2. Contain

The video should fill the available space while preserving its aspect ratio, so it will be “letterboxed” if its aspect ratio does not match the aspect ratio of the container.

Positions

It is important to know that vertical or horizontal positions are only available depending on the aspect ratio of the video and its container.

You have the choice between:

• Center (default), Left and Right for Horizontal Alignment
• Center (default), Top and Bottom for Vertical Alignment

Filter and Opacity

You can add filters (Lighten, Darken, Grayscale, Sepia, Blur) to your videos or opacity. Note that those options are more often useful when working with images instead of videos.

Note that the above options are not available for videos from YouTube. We recommend adding those to an empty slide to have them displayed on full-scale on the slide.
