# Video Subtitle Embed Embed subtitle files as soft subtitles in videos (switchable subtitle tracks, not burned into video) > Canonical page: https://elysiatools.com/en/tools/video-subtitle-embed - **Category:** Media - **Keywords:** video, subtitle, embed, soft, track, srt, ass, vtt, caption, add ## Overview The Video Subtitle Embed tool allows you to seamlessly integrate external subtitle files—such as SRT, ASS, SSA, or VTT—directly into your video files as soft, switchable subtitle tracks. Unlike hardcoding or burning subtitles into the video frame, this tool preserves the original video quality and gives viewers the flexibility to toggle subtitle tracks on or off, select languages, and keep existing subtitle tracks intact across formats like MKV, MP4, WebM, AVI, and MOV. ## Inputs - **Video File** (file): Select the video file to embed subtitles into - **Subtitle File** (file): Select subtitle file to embed (SRT, ASS, SSA, or VTT) - **Keep Original Subtitles** (checkbox): Preserve existing subtitle tracks in the video - **Subtitle Language Code** (text): ISO 639-2/B language code for the embedded subtitle - **Output Format** (select) ## When to use - When you want to add multiple language subtitle tracks to a video without permanently burning them into the video image. - When you need to package SRT, ASS, SSA, or VTT subtitle files directly into a single video container for easier sharing and playback. - When you want to preserve existing subtitle tracks in a video while adding a new, switchable translation track. ## How it works - Upload your source video file and select the corresponding subtitle file in SRT, ASS, SSA, or VTT format. - Configure your preferences, such as setting the ISO 639-2/B language code, choosing whether to keep original subtitle tracks, and selecting your preferred output container format. - Process the files to merge the subtitle track into the video container as a soft, switchable stream without re-encoding the video. ## Use cases - Adding localized subtitle tracks (e.g., English, Spanish, French) to a movie file for multi-language distribution. - Packaging timed captions (VTT or SRT) into lecture or training videos for accessibility compliance. - Consolidating raw ASS styling subtitles into anime or fan-subbed videos while retaining advanced typesetting. ## Frequently asked questions ### What is the difference between soft subtitles and burned-in subtitles? Soft subtitles are embedded as a separate, switchable text track inside the video file, allowing viewers to turn them on or off. Burned-in (hard) subtitles are permanently merged into the video frames and cannot be disabled. ### Which subtitle formats does this tool support? The tool supports SRT, ASS, SSA, and VTT subtitle formats. ### Will embedding soft subtitles degrade my video quality? No, embedding soft subtitles does not re-encode the video stream, meaning your original video quality remains completely untouched. ### Can I keep the existing subtitle tracks already present in my video? Yes, by enabling the 'Keep Original Subtitles' option, the tool will preserve all pre-existing subtitle tracks alongside the new one. ### What output formats can I choose for my video? You can export your video in MKV, MP4, WebM, AVI, or MOV formats, with MKV being highly recommended for optimal subtitle compatibility. ## Related tools - [Batch Video Watermark](https://elysiatools.com/en/tools/video-batch-watermark): Add text watermark to multiple video files with customizable position, font size, color, opacity, and timing - [Video Subtitle Add](https://elysiatools.com/en/tools/video-subtitle-add): Add hardcoded subtitles to videos using SRT, ASS, or VTT subtitle files with customizable font styling - [ASS to SRT Converter](https://elysiatools.com/en/tools/video-subtitle-ass-to-srt): Convert ASS/SSA subtitle files to SRT format - [SRT to ASS Converter](https://elysiatools.com/en/tools/video-subtitle-srt-to-ass): Convert SRT subtitle files to ASS/SSA format with customizable font styling - [Video Watermark Text](https://elysiatools.com/en/tools/video-watermark-text): Add text watermark to videos with customizable position, font size, color, opacity, and timing - [Audio to Text Transcriber (AI)](https://elysiatools.com/en/tools/audio-to-text-transcriber): Transcribe speech from audio (wav/mp3/m4a/flac/ogg/webm/aac) to text, SRT, VTT or JSON using the grok-stt AI model.
