Frequently Asked Questions
Can I show different text at different times?
There is no text timeline in this tool. Use Burn Subtitles for timed text from a prepared subtitle file.
Does the text remain editable in the MP4?
No. The text is rendered into the video frames. Keep the original to make a different version later.
