    常見錯誤

    • Uploading a video file too large for the browser (keep it under 2 GB).
    • Closing the tab before processing finishes: the conversion stops.
    • Using an exotic input format (prefer MP4, WebM, MOV, AVI).
    • Picking a bitrate so low that quality drops noticeably.

    專業技巧

    • Pick H.264 (MP4) for the widest compatibility.
    • For the web, use WebM (VP9/AV1): smaller file at the same quality.
    • Keep the original: processing is local but the download is final.
    • On mobile, plug in the charger for long videos.

    常見問題

    是的,您可以為文字選擇多種字體、顏色、大小和位置。

    Yes, full palette: ~30 fonts (classic, modern, handwritten, decorative), free point size, free color (color picker + hex code), black/white outline for readability on varied backgrounds, drop shadow for depth effect, adjustable opacity for semi-transparent text.

    Yes, each text has a start and end timecode on the timeline. You can add multiple texts at different moments (title at start, subtitles during, credit at end) and animate their appearance/disappearance (fade, slide) for a professional look without dedicated software.

    Yes, free drag-and-drop on the preview, or preset positions (top/center/bottom × left/center/right). Exact coordinates are shown in pixels and you can fine-tune via keyboard for pixel-perfect placement.

    The text is integrated ("burned-in") directly into the video pixels, so it stays visible no matter the re-compression or re-upload on Instagram, TikTok, YouTube. This is more robust than external subtitles (SRT) which can be ignored by players.
