About Add Subtitles to Video
Last updated: May 2026
OptiPix Add Subtitles는 비디오 픽셀에 직접 자막 텍스트를 태웁니다. 비디오와 SRT 파일을 업로드하거나 타임스탬프와 함께 수동으로 자막을 입력하세요. 글꼴 크기와 위치를 사용자 지정하세요. 자막은 영구적으로 포함되어 별도의 자막 파일 없이 모든 플레이어에서 표시됩니다. FFmpeg.wasm 자막 필터를 사용합니다.
How It Works
FFmpeg.wasm -vf subtitles 필터는 SRT 파일을 읽고 지정된 타임스탬프에서 비디오 프레임에 텍스트를 태웁니다.
Use Cases
- •접근성을 위한 캡션 추가
- •소셜 미디어를 위한 자막 태우기
- •비디오에 번역 추가
- •자막 튜토리얼 만들기
- •캡션이 모든 곳에서 표시되도록 보장
