A funny thing happened to me when I started creating videos for our YouTube Channel. The thumbnail preview was taken from my introduction slide. (1-2 minutes from the start)
I thought it was strange that it would arbitrarily pick a time to use as the thumbnail. I’m sure there’s a perfectly good reason to do this, but that’s for another time.
Many, many years ago, I bought an application called Tag&Rename that I used to re-tag my MP3 collection. Well it just so happens that it allows for re-tagging other media types, like video such as .mp4,
If you haven’t seen Tag&Rename, click on the link and download it for a test drive. After you’ve finished trying it out, you’ll gladly pay the $29.95 like I did.
How To Do Change the Thumbnail:
1. So while I’m in Windows Explorer, I right click the media file and click Open in Tag&Rename. This will launch the Tag&Rename application.
2. In the Tag&Rename application, right click on the media file and click Edit File Tag.
3. In the Tag Editor window, click the Add button.
4. In the Find art file window, navigate and select where your graphic image is located and click Open.
NOTE: only .bmp, .jpeg, .jpg, .png, and .gif image formats are accepted.
5. In the Tag Editor window, click Save and close Tag&Rename.
6. Which back to Windows Explorer and press F5 to fresh. Your custom video thumbnail is no displayed.
