To edit a video thumbnail in Sendspark, open the thumbnail editor from the video edit page (click “Edit thumbnail”) or from the share modal (click “Customize”). From there you can add a text overlay, personalize it with dynamic variables, add the viewer’s logo, select a different preview frame, toggle static vs. animated, and change the colors, the duration badge, and the play button.

Key takeaways

  • Thumbnails show up where the video is shared as a link, in email and in LinkedIn, but not on the video page itself. Your edits carry into those previews.
  • You can launch the thumbnail editor two ways: click “Edit thumbnail” on the video edit page, or click “Customize” in the share modal.
  • You can add a text overlay (keep it to ~5 words), personalize thumbnails with dynamic variables that map to your contacts (with editable fallback text), and add the viewer’s company logo.
  • The Edit Preview tab lets you pick a different frame and toggle static vs. animated; the Edit Styles tab controls colors, the duration badge, and the play button, and these changes affect only that specific video, not your workspace’s global styles. To change the text and banner colors behind a thumbnail caption, see edit thumbnail caption colors.
Congratulations on creating your video! Now let’s make sure you make a great impression when you share it by customizing your video thumbnail!

Video Thumbnail Overview

Video thumbnails are what show up in emails. They are extremely useful to cut through the noise and capture your viewer’s attention! A Gmail compose window with a Sendspark video thumbnail embedded, captioned "Elizabeth, to answer your question..." with a 0:42 duration badge and a Watch Video link beneath **Note:**Thumbnails show up where your video is shared as a link, not on the video page itself. That means email, and also LinkedIn, where your customized thumbnail carries into the preview. So when you edit a thumbnail, you’ll see your edits in those places, but not on the video page. For LinkedIn specifically, see tips for sending videos over LinkedIn messages and LinkedIn video comments show GIF thumbnails. We highly recommend customizing video thumbnails because they provide a teaser for your video. You can let your viewer know what this video is about, and why they should click “play!”

How to Edit Video Thumbnails

Scroll through all of the possibilities below, or skip ahead to learn how to make a specific edit:

Launch the thumbnail editor

There are a couple of places you can launch the video thumbnail editor. You can use either of these options. (The video thumbnail editor will be the same no matter where you launched it from).

Option A. Shortcut

  • Click on the video edit page for the video you want to share
  • On the top right, click the icon for “Edit thumbnail”

Option B: From the share modal

You can also get to the thumbnail editor from the video share modal. Simply click on the **“Customize”**button on the top right of the video preview in the share modal to launch the thumbnail editor. The share modal on its Share tab, with a Customize control over the video preview

Add a Text Overlay

Start typing right under “text overlay” to add text to your video thumbnail. We recommend keeping this to ~5 words to make it easy for your viewer to see the note in just one glance. The Text Overlay field with sample caption text typed into it Once you start typing, you’ll see the words show up on the video thumbnail preview immediately. If you don’t like the text color or background color, no worries! You’ll be able to change that later.

Dynamically personalize thumbnails

Let’s say you are sending one video to multiple people, and you want each video thumbnail to show the viewer’s name. You can automatically personalize videos using dynamic variables. Simply select “personalize” and insert the variable that you want to use. The Edit Thumbnail modal with the Personalize button open, listing merge tags for First Name, Company Name and Job Title, each with its fallback When you send your video through your email automation platform of choice, we will map the dynamic variable placeholder in Sendspark to the contact property in your sending platform, so each viewer will see their own name. (Learn how to share dynamic videos) If we can’t get the contact variable for any reason, we will show a fallback variable. For example, “Hi #{{first name}}” would show “Hi there.” To change the fallback variable, simply click on the dynamic variable you’ve inserted, and write in new fallback text. The Insert Merge Tag dialog showing a Merged field of firstname and an editable Fallback text field Want to add your viewer’s logo to the video to make it really pop? Simply search for their company name or domain underLogo Overlay. The Logo Overlay field with "Salesforce" typed, offering matching companies with their domains Once you see their logo, click on it, and it will appear in the top left of the video thumbnail. The thumbnail preview with the chosen company logo placed in its top left corner If you don’t see the logo you’re looking for, you can try to find it on your own through a Google search, or by going to their company’s LinkedIn/Twitter/Facebook pages, and then uploading it to Sendspark via the **“upload logo”**button.

When you edit your global styles, they affect all videos in the workspace. However, when you edit your video thumbnail styles, they only affect this specific video.

Frequently asked questions

Wherever your video is shared as a link, which means email and LinkedIn. Your customized thumbnail carries into both. The edits do not display on the video page itself, since the page plays the video rather than showing a thumbnail.
There are two ways. Click the “Edit thumbnail” icon on the top right of the video edit page, or click the “Customize” button on the top right of the video preview in the share modal. The editor is the same wherever you launch it from.
Yes. Select “personalize” and insert the dynamic variable you want to use. When you send the video through your email automation platform, Sendspark maps the variable to the contact property in your sending platform so each viewer sees their own name. If a value is missing, a fallback (which you can edit) is shown instead.
Click into the Edit Preview tab of the thumbnail editor and drag the slider to the frame you want. You can also switch between an animated GIF thumbnail and a static image thumbnail under Thumbnail Type in the same tab.
No. Editing thumbnail styles affects only that specific video. This is different from editing your global styles, which apply to all videos in the workspace. Sendspark reuses the same color theme on your next video for convenience, but it never changes other existing videos.
