Changelog

2.1.1 - February 12, 2026

Upgraded frame-rate conversion to use math-based motion interpolation instead of simple frame duplication when increasing FPS.
Added increase-only behavior for frame synthesis: FPS decreases now downsample frames without interpolation artifacts.
Applied the improved FPS logic to preset and custom frame-rate selections for consistent output behavior.

▶

Added internal FFmpeg automated test runner at /internal/ffmpeg-option-tests for one-click option + matrix coverage.
Centralized command generation so production conversions and test harnesses run from the same FFmpeg command builder.
Added fixture-manifest workflow and one-command FFmpeg test UI launcher for repeatable local validation.
Improved visual before/after verification with synced playback controls and safer preview fallback handling.
Hardened FFmpeg runtime recovery and added regression guards for known aspect-ratio failures, including 21:9 behavior.

▶

Fixed a mobile display issue where FAQ, Changelog, About, Legal, and Contact links were not visible.
Ensured the "Made By" footer is also visible on mobile devices.
Corrected outdated text on several pages that still referenced audio conversion. This was a leftover from when the site transitioned from Audio Converter Hub to The Video Converter Hub.
Removed all ad placeholder elements. These were originally added to help cover the site’s domain and development time, but have been removed for now as the site is using a free domain.

▶

Complete overhaul of the user interface.
Introduced new video conversion commands and features.
Significantly improved the site codebase to support faster and more frequent updates.
Major update to command structure: enhanced existing tools and added entirely new functionality.
