What are the difficulties of subtitle generation?
Many people think of subtitling as “typing a few words”, but in reality, subtitling usually involves three core components:
- Speech to text (speech recognition)
- Timeline synchronization (Timecoding)
- Subtitle format output and translation
Mistakes in any of these three steps can result in inaccurate and unsynchronized subtitles, affecting the viewing experience or even preventing import into the platform.
Creating subtitles manually is time-consuming and error-prone!
Traditional subtitling requires typing while listening and manually adjusting the start and end times of each sentence. A 10-minute video can take over an hour to complete basic subtitling. If bilingual subtitles are required, additional translation and typesetting will be required.
Free tools are plentiful, but so are the problems
Although there are some so-called “free subtitle tools” on the market, you are likely to encounter the following problems in actual use:
- Limit video length or times
- Unable to export 選擇性RT/VTT files
- Doesn’t support multi-language translation or inaccurate translation
- Complicated interface, difficult for newbies to get started
- Watermarks, castrated features, and forced to pay for upgrades.
So many people ask: “Is there any really free and good subtitle generator?”
The answer is: yes, for example, Easysub offers a free trial program to generate multilingual subtitles in one click without downloading.
Next, we’ll cover the types of free subtitle generation tools and how to choose the right subtitle solution for your video.
Do free subtitle generators really exist?
The answer is obvious: free subtitle generators do exist!
