Custom Thumbnails
Upload custom thumbnails for platforms that support them or select a frame from your video as the thumbnail.
How It Works
When uploading a video, you can upload custom thumbnails for platforms that support them. Simply click on the thumbnail upload area for the platform you want to customize and choose your image. For some platforms that, you can select a frame from your video as the thumbnail.
For platforms that don't support custom thumbnails, the first frame of your video will be used automatically.
