Selecting the Thumbnail and Preview Image from the Media While you CAN select an animated gif as your custom uploaded image, we do not support animation in the thumbnail we will use the first still image from the gif.If you upload a larger/smaller image, we will scale the image up or down to meet either the width or height (whichever is closest), then allow you to crop or rotate the image yourself. For custom uploaded images, we maintain a 16:9 ratio and 1280x720 dimensions.If you want to have a custom thumbnail for your interactive media, you MUST set that image on the video FIRST, then add polls to the video. As stated in the note at the top of the page, interactive media cannot be edited through the Echo360 video editor.Safari is fine for all other Echo360 media editor functionality. You CAN upload a custom image to use, but you cannot select an image from the media.
There is a long-standing issue with WebKit (the browser engine used by Safari) where users cannot select an image from URL-served content (as Echo360 media is). If you are using Safari, you should stop and use a different browser to set your thumbnail.There are a few items we want you to be aware of before you use the Set Thumbnail feature for your Video/Audio media: You can also revert to the original image at any time. The thumbnail customization feature allows you to peruse the entire media for just the right still-moment, then select an image from the video (or from either track for dual track media), OR upload your own custom image. In addition, the thumbnail is also the preview image that users see for media posted or embedded outside of Echo360, prior to playback. The thumbnail is what users see on the media tile in the Library or in a Group, and what administrators see in the Captures page. For dual-track media the thumbnail is always pulled from Channel 1 (labeled as Video 1 in the editor). By default, the Echo360 media processor uses a still frame from near the beginning of the recording. The ability to customize the thumbnail image shown for video or audio media is done through the Echo360 video editor. You cannot currently edit the video portion of interactive media you can only add, remove, or edit the embedded polls, and as such the Edit Media command for interactive media is disabled. It does not apply to interactive media (videos with polls embedded in them). However, the information and procedures also apply to any audio-only files you may have. A Note on Terminology: Since the editor is primarily designed for video editing, this article uses the term "video" for the media being edited.
