Which one should you pick?
Pick Aegisub if
You’re building around post-production subtitle work with precise timing and ass karaoke styling. Aegisub is the canonical open-source subtitle editor and still the right tool for ASS work — karaoke timing, fansub-grade styling, frame-accurate adjustments. The official repo woke up again in 2026 after years of slow activity, with portable 3.
Pick Submagic if
You’re building around short-form social clips. Submagic does one thing — make a long video look good as a vertical caption-heavy clip — and does it fast. Captions are punchy, templates feel current, and it's catching attention from podcasters tired of paying Opus for similar output.
