Upload the MP4 file and the converter produces a HLS from it — depending on the target, that is a text transcript of the spoken audio or a contact-sheet document of sampled frames. The MP4 itself stays untouched; the HLS is generated from its contents.
Will the HLS contain a transcript of what is said in the MP4?
+
When the target is a text document, yes — speech in the MP4 is transcribed into the HLS as editable text, so you get a searchable written record of the video's spoken content.
Колико је прецизна транскрипција од MP4 до HLS?
+
Accuracy is high for clear speech with little background noise, and lower for crosstalk, heavy accents, music beds, or poor audio. A clean MP4 recording produces the most reliable HLS text.
Can I choose the spoken language of the MP4?
+
Yes — set the source language in advanced options so the recognizer loads the right model. Matching the language to the MP4 audio noticeably improves the HLS transcript quality.
What if the HLS is a frame contact sheet rather than text?
+
For image-document targets the converter samples frames across the MP4 timeline and tiles them into a HLS document — a visual index of the video you can scan, print, or share without playing the whole clip.
Is the HLS text editable and searchable?
+
Yes — a transcript HLS is real text, so you can edit, correct, search, and copy from it. That is the point of turning a MP4 video into a document rather than leaving it as a media file.
Can I convert several MP4 videos to HLS at once?
+
Yes — drop multiple MP4 files and each produces its own HLS in parallel. Useful for transcribing a batch of recordings or indexing a set of clips.
Колико дуго траје MP4 до HLS?
+
Транкрипција вага са изговореним трајањем MP4; лист контакта је бржи јер је само узорци оквира. У сваком случају, на основу сервера, ваш уређај није уско уско.
Will timestamps appear in the HLS transcript?
+
Where supported, the HLS can include timestamps so each passage maps back to its moment in the MP4 — handy for captioning, review, and citation. Enable timestamps in advanced options.
Да ли је мој MP4 видео приватно током претварања?
+
Yes — the MP4 and the generated HLS are processed in isolated workers and deleted within minutes. No human reviews the footage or the transcript. See /privacy/.
Могу ли добити субтитлове уместо обичне HLS транскрипта?
+
For caption-style output, use the dedicated subtitle tool which emits SRT / VTT timed to the video. This MP4 to HLS flow focuses on a document — a plain transcript or a frame contact sheet.
Do I need any software to convert MP4 to HLS?
+
No — transcription and document assembly run on our servers. You only need a HLS-compatible viewer or editor to open the result.
