Best Practices for Combining Videos with HeyGen
A few quick adjustments can make your merged video look smoother. Try to keep your clips at similar resolutions to avoid noticeable shifts in quality. If your videos were shot in different orientations, use cropping or layout tools to keep the subject centred and easy to view. Check the audio levels so transitions feel natural, and trim any moments you do not need. Choose an aspect ratio that suits your platform, and preview the video before exporting to ensure everything flows smoothly.
