ViralMint merges up to 10 clips into one video on your own machine — mismatched resolutions and aspect ratios are normalized automatically, with an optional crossfade between cuts.
Phone clips, screen recordings and downloads never share a resolution. ViralMint normalizes every clip to the target aspect — 9:16, 16:9, 1:1 or matched to your first clip — so the merged video plays as one piece instead of jumping between frame sizes.
The bundle option renders the same merge three times — 9:16 for TikTok and Reels, 16:9 for YouTube, 1:1 for feeds — and hands you a ZIP with all three files named per platform.
Merging runs on your own CPU with FFmpeg. Nothing uploads, there's no queue, no watermark, and a 4K merge is limited only by your disk speed.
Launch ViralMint and open Tools → Merge Clips.
Drop in files or pick from your ViralMint library — the order you add is the order they play.
Choose the output aspect (or auto-match the first clip) and hard cuts or crossfade.
FFmpeg normalizes and stitches locally; the finished mp4 (or 3-aspect ZIP) lands in your library.
Just add them — ViralMint re-encodes each clip to the target resolution and aspect ratio before stitching, using center-crop so nothing letterboxes unexpectedly. The output plays as one consistent video, not a slideshow of frame sizes.
No. The merge runs locally on your machine with FFmpeg — there's no watermark, no upload, and no subscription. It's priced as a small flat per-merge fee from a prepaid balance, not a monthly plan.
Yes — choose a crossfade and ViralMint inserts a dissolve at every cut. Hard cuts remain the default because they're what short-form pacing usually wants.
Yes. The 'all platforms' bundle runs the merge at 9:16, 16:9 and 1:1 and delivers a ZIP with the three files — one merge, every aspect your platforms need.
The Video Merger ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
