Best practices for combining videos with HeyGen
A few quick adjustments can make your merged video look smoother. Try to keep your clips close in resolution to avoid noticeable quality shifts. If your videos were shot in different orientations, use cropping or layout tools to keep the subject centred and easy to watch. Check your audio levels so transitions feel natural, and trim the moments you don’t need. Pick an aspect ratio that fits your platform, and preview your video before exporting to make sure everything flows well.
