Frequently Asked Questions
What is SUP Format?
The SUP format is a generic container for image-based subtitles, most commonly associated with DVD and Blu-ray discs. On DVDs, these are called VobSub (.sub/.idx), and on Blu-rays, they are PGS (.sup). In both cases, the subtitles are stored as a stream of images, not as text. This ensures consistent visual appearance across all players but makes them large and impossible to edit as text.
What's the difference between PGS and SUP?
PGS is a specific type of SUP stream used for Blu-ray discs. 'SUP' is often used more generically to refer to any image-based subtitle stream, including those from DVDs (which are technically VobSubs). Our converter correctly identifies and handles these different image-based formats.
How do I convert a SUP file to SRT?
Converting an image-based format like SUP to a text-based format like SRT requires Optical Character Recognition (OCR). This process involves software scanning the images of the subtitles and attempting to recognize the characters to convert them back into text. The accuracy can vary depending on the quality and font of the subtitles.
How accurate is the AI transcription?
Our AI transcription service provides highly accurate results, with precise timing and synchronization for SUP files. The system is trained on millions of hours of content to ensure professional-quality output.
Can I edit the subtitles after generation?
Yes, you can easily edit the generated SUP files using any compatible subtitle editor. The files are provided in standard format for maximum flexibility.
