Eklipse Studio is an AI-powered editing tool that turns horizontal gaming clips into short-form videos for TikTok, Reels, and Shorts. Just drop in your Twitch or Kick clip URL, pick a template, and let the AI handle the layout, captions, effects, and formatting.

A vertical video editor is a tool designed to convert or rotate horizontal videos into vertical (9:16) format. One of the top tools for creating vertical videos is Eklipse. Unlike traditional editors, it automatically adjusts horizontal gameplay or footage to vertical without cutting out important elements like HUDs, killfeeds, or key actions, making your clips ready for TikTok, Instagram Reels, and YouTube Shorts.

The best aspect ratio for gaming shorts is 9:16 (vertical). This format is optimized for TikTok, Instagram Reels, and YouTube Shorts, ensuring your gameplay fills the screen on mobile devices. Using 9:16 keeps all key elements visible, including HUDs, killfeeds, and facecams, so viewers experience the action without missing important details. You can also use tools like Eklipse to automatically resize and crop your gameplay for perfect vertical viewing.

Eklipse Studio packs everything you need to turn streams into viral shorts. Use TikTok-style vertical templates, smart trimming, AI-powered captions, draggable webcam/gameplay layers, and DMCA-safe music. Seamlessly export to TikTok, YouTube Shorts, or Reels.

To add AI-generated captions and stickers in Eklipse Studio, select a clip, open it in the editor, and choose a vertical template. Toggle on auto-captions to generate styled subtitles instantly. Then drag and drop stickers, text, or overlays to customize your video. The AI aligns everything for TikTok, Reels, or Shorts.

Eklipse Studio offers vertical templates designed for TikTok, Reels, and Shorts. You can choose from split-screen layouts, webcam overlays, meme-style designs, and bold text formats. Every template is optimized for gaming highlights and quick editing that’s ready to post.
