What's New in Version 1.0.1

Latest Release Update

What's New in Version 1.0.1.0
1. Massive Format Support Update: We've massively expanded our format support! You can now import 28 different video formats (including 3GP, AVI, FLV, MKV, MOV, MP4, MPEG, TS, WMV, WEBM, and many more).
2. More Export Options: Added support for exporting to 9 of the most popular video formats (MP4, HEVC/H.265, MKV, AVI, MOV, WEBM, WMV, FLV, and TS).
3. Dramatically Improved Compression: We completely rewrote our compression engine. The "Convert & Compress" mode is now much smarter and significantly more aggressive at reducing file sizes while maintaining excellent visual quality.
4. Guaranteed 2GB Output: A new smart-scaling rule guarantees that any video under 4 hours long will always stay comfortably under 2GB after compression.
5. Lightning Fast "Just Convert" Mode: If you just need to change the file format without altering the resolution, the app now uses a lightning-fast stream copy method that finishes almost instantly with zero quality loss.
6. Fixed Resolution Scaling: You can now perfectly upscale or downscale your videos (e.g., 1080p up to 4K, or 4K down to 720p). The app intelligently handles the resizing while preserving the correct aspect ratio.
7. Drag & Drop Improvements: The drag-and-drop file upload experience has been polished to be smoother and more reliable.
8. Under-the-hood stability improvements and better video codec matching (especially for WMV and AVI exports).
