 If you want to create vertical video in Ecum Live to use on TikTok, Instagram, or YouTube Shorts, then it couldn't be easier, and I can tell you how to do it in less than a minute. All you need to do is go up to the menu bar when you've got Ecum Live open, and find the options menu, come down to the stream aspect, and then move over and change that to the tall 9x16. Now, this won't actually change the appearance of the output window itself in Ecum Live. However, there will be a column down the middle of it that you'll notice that everything will sort of snap to, and that is now the new area that you'll have for your output. You can create overlays obviously, so instead of 1920 by 1080, just make them 1080 by 1920, and you can then have those as vertical overlays, and that's all I've done to create this little overlay around me. As soon as you export it, it will be exported as a vertical video, and you'll be able to upload it to Instagram, TikTok, or YouTube Shorts. Have a great day.
