Tips for youtubers
Import by URL
Paste your YouTube video URL and ViralWiz fetches and transcribes it automatically. No manual download required.
Pick the best 60 seconds
Use the clip trimmer to select the most engaging minute from your long-form video. Hooks, revelations, and emotional moments perform best.
Use uppercase animated captions
The most viral short-form content uses large, uppercase, word-by-word subtitles with a dark stroke. This style is built into ViralWiz's default presets.
