Using Wave.video Editor is the easiest way to create or customize branded or transparent elements for your video, custom overlays, low third or video frames.
After you are done with the easy part - designing, there is a tricky part - publish in the format that will be useful for your video with transparent elements.
What should you know before you make your decision of publishing video format:
1. Transparent videos are only supported in Chrome!
Other browsers don't support transparent videos - which means whoever will look at your transparent video in other browsers: IE, Firefox, Safari, Opera, etc, will see blacks parts instead of transparent parts.
2. Good news All the browsers support .gifs.
Be mindful of it when you create gifs. gifs are heavy in size and it's helpful to keep the size down for better performance in browsers.
3. When you create an overlay or low third or other graphical elements for a browser-based live streaming platform such as Streamyard, Restream or Melon keep point #1 above^^^ in mind. The listed platforms only support transparent gifs. Again those listed platforms don't support .mp4 or .mov video formats for transparent videos.
[In order to have an effect of graphic that overlays your video you need to have part of the screen transparent]* - doesn't sound clear.
4. When creating an overlay or low third or other graphical elements for desktop live streaming platforms such as: Ecamm, OBS, Streamlabs etc. keep in mind that those platforms don't depend on browsers when it comes to displaying overlays and transparent videos. Therefore you may proudly publish your transparent video.
