Frequently Asked Questions

Subtitles are hardcoded and burned directly into the video frames. This means they display on any player, device, or social platform without needing subtitle support.
Can I customize subtitle font, size, and position?▼
Basic customization is available. For advanced subtitle styling, edit the SRT file's timing and use a desktop editor for font customization before uploading.
