Lt uses the widely popular H.264 format to display videos, ensuring compatibility across the web. Preparing videos in this format is straightforward, but key encoding parameters can affect streaming quality for your students. This guide outlines the essentials for correctly preparing your videos for Lt. Additionally, Lt supports embedding YouTube videos, offering another flexible option for video content.
If you're exporting videos using editors like Adobe Premiere Pro, Apple Final Cut Pro, or Sony Vegas, this guide is for you. If these tools sound unfamiliar or "encoding parameters" seem daunting, head straight to our Handbrake guide for an easier solution!
Quick Check: File Extensions
Verify your videos are suitable for Lt by checking their file extensions. H.264-formatted videos should have either:
- .mp4
- .m4v
Video Upload Size Limit
Video uploads are limited to 2GB per file. This limit supports several hours of video content in most standard formats and resolutions.
If you do need to reduce the file size, we recommend using our Handbrake guide.
Embedding YouTube Videos
In addition to uploading H.264-formatted videos, Lt allows you to embed YouTube videos directly into your lessons. This option is particularly useful for leveraging pre-existing content or videos hosted on YouTube. To embed a YouTube video:
- Copy the YouTube video URL.
- Paste the URL into the video panel in Lt.
- Ensure the video settings on YouTube allow embedding.
Embedded YouTube videos are streamed directly from YouTube, ensuring fast playback without additional encoding requirements.
Enabling Video Streaming
To ensure your videos stream effectively, they must be configured for "streaming". This allows students to start watching a video immediately, even before it has fully downloaded. When exporting your videos, enable the following options in your video production software:
- "Web optimization"
- "Progressive download"
- "Fast start"
These settings allow the video to load seamlessly in Lt. Without streaming optimization, viewers must wait for the entire video to download before playback begins.
Handling Non-Optimized Videos
Lt prevents non-streamable H.264 videos from being added to video panels. If your video isn’t optimized for streaming, Lt will alert you during upload. Don’t worry—such files can easily be fixed using Handbrake, a free utility that converts videos into Lt-friendly, streamable H.264 files.
