Guides and tests on dubbing, subtitles, lip sync and avatar videos in four languages: translation quality, voices, timing, price and data handling.
Converting ASS to SRT keeps the text, timing and italics, but not fonts, positions, karaoke or drawings. Our own sample file shows what goes, and how FFmpeg, Subtitle Edit and Aegisub each decide.
A TXT transcript has no timing, so converting it to SRT means adding timecodes. Three ways to do it, a short script, and what our sample showed in four languages when checked against reading-speed limits.
Sub keeps the original voices with subtitles, dub replaces them. Why the two never say the same thing, what studies found, who needs which, and how to switch on Netflix, Prime Video, Disney+, YouTube and Crunchyroll.
YouTube's own transcript is free and often all you need. How to open, search and copy it in the three panel versions we found, fix glued timestamps, and what generator sites and AI summaries add.
How to turn YouTube subtitles on or off on a computer, phone or TV, keep them off for every video, change the language and the caption style, and why captions keep switching on by themselves. Checked in October 2026.
A .vtt file holds captions in the WebVTT format: a WEBVTT header, timed cues and text. Our sample file line by line, VTT vs. SRT, how to open and convert it, and what made captions vanish in our Chrome test.
We pasted the same SRT file into Google Translate, DeepL and Bing, in German, French and Spanish: which kept it intact, where the free limits cut long files, and why every translation still needed editing for length and reading speed.
LRC files only say when each line starts; SRT also needs an end. How to convert with Subtitle Edit, FFmpeg or an online tool, what converters guess, and why YouTube takes LRC as it is. Shown with our own lyric file.
Turn subtitles into plain text you can read, search or summarize: with Subtitle Edit, four find-and-replace steps in any text editor, or an online converter. Tested on our own SRT file.
Dubbing replaces a video's voices with new ones, usually in another language. How it differs from voice-over and subtitles, how studios and AI tools make dubs, where audiences expect them, and what we saw in YouTube's audio track menu.
TikTok shows captions but has no transcript or export. What we found in TikTok's web player, how to turn captions and translations on, the clean route for your own videos, and what transcript generators actually do.
Translate any YouTube video's captions with Auto-translate, switch to dubbed audio where it exists, and, as a creator, add translated subtitles, titles and your own dubs. Checked in October 2026 on a real video.
Download the caption file of your own videos in YouTube Studio, copy the transcript of any video, and turn a transcript into a valid SRT file, plus what YouTube's terms say about subtitle downloader sites.
Subtitles carry the dialogue for viewers who don't understand the language; closed captions add the sounds for viewers who can't hear them. Shown with our own sample files in four languages, plus SDH, open captions, labels and the rules.
Get the original audio back on one video in three clicks, stop most dubs and translated titles with Preferred languages, and switch automatic dubbing off as a creator. Steps checked in October 2026, with what we saw on a dubbed video.
An SRT file is a plain-text subtitle file: numbered blocks with a start time, an end time and a line of text. We built one in English, German, French and Spanish to show what a wrong encoding does, and how to create, translate and upload one that works.
