My text captions
Up to 240 characters. Line breaks allowed; up to four lines in the MP4.
SRT keeps text and timing, without position or size. UTF-8 import; simple styling is removed. Speech is not transcribed automatically.

How to use this tool
- Choose a video or try the example.
- Write captions and set their start and end with the player or time fields.
- Choose position and size, check the preview, then download the MP4 and SRT.
Is speech recognised automatically?
No. Write your text or import a UTF-8 SRT. There is no automatic transcription or translation.
How do MP4 and SRT differ?
MP4 contains text burned into its images, visible without a separate file. SRT keeps only text and timing, without position or size.
Can two captions appear together?
This first version shows one at a time. Overlapping intervals block export. Times are applied to the precision of one frame in the 30 fps output.
What happens to the sound?
The first track is kept as stereo AAC; others are omitted. Keep the original and check the sound: the MP4 is re-encoded.
