How CAP Handles RST Data
reStructuredText encodes data using mathematical algorithms that preserve every data point. CAP Subtitle prioritizes exact data preservation. The conversion maps between these approaches intelligently. reStructuredText's known limitation — less intuitive syntax than Markdown for some constructs — is resolved when converting to CAP Subtitle, which offers broadcast-standard caption format for TV. The reStructuredText source uses lossless encoding. The CAP Subtitle output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient.
This is a cross-category conversion from Document (reStructuredText) to Subtitle (CAP Subtitle). While these formats serve different purposes, Xonvert extracts the compatible data from your reStructuredText source and maps it into the CAP Subtitle format. Document files typically contain Python documentation, while Subtitle files are used for broadcast television closed captioning. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.

RST to CAP Conversion: Your Questions Answered
