How KEY Handles CAP Data
For subtitle-to-document conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both CAP Subtitle and Keynote Presentation. Cross-category conversions require additional adaptation, which Xonvert handles automatically. Document structure and formatting are preserved to the maximum extent supported by both formats. When converting from CAP Subtitle to Keynote Presentation, the conversion is lossless, meaning every bit of data is preserved exactly as in the original.
This is a cross-category conversion from Subtitle (CAP Subtitle) to Document (Keynote Presentation). While these formats serve different purposes, Xonvert extracts the compatible data from your CAP Subtitle source and maps it into the Keynote Presentation format. Subtitle files typically contain broadcast television closed captioning, while Document files are used for Apple users for presentations. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
