General improvements ⊡ Bug fixes, code cleaning, and overall performance improvements ⊡ Updated dependencies to enhance stability and compatibility

▼ NEW

Keep frames widget ⊡ Added new widget to choose whether to save upscaled video frames ⊡ Selecting “Enabled”, upscaled frames will not be deleted ⊡ This allows you to re-encode upscaled video with different extension without upscaling again

AI models update ⊡ Updated AI models using updated tools ⊡ Improved upscale quality ⊡ Improved GPU compatibility and upscaling performance

GPU Auto selection ⊡ Added new "Auto" option in GPU Widget ⊡ Selecting “Auto,” the app automatically choose the most powerful GPU in the PC ⊡ This solves a problem with GPU processing on notebooks with 2 GPUs

▼ BUGFIX / IMPROVEMENTS

FFMPEG audio passthrough ⊡ This feature allows audio to be processed without any alterations (lossless quality) ⊡ Supports multiple audio streams (when a video contains multiple audio tracks) ⊡ This function fix an issue where audio could not be applied to upscaled videos

Video upscale improvements ⊡ Improved video upscale stability and memory usage ⊡ Updated FFMPEG to version 7.1 (video encoding bugfix and performance improvements) ⊡ Now the app automatically removes the temp folder when the video upscale is finished

Video encoding improvements ⊡ Updated MoviePy to version 2.0 ⊡ A long list of bugfixes and optimizations for video encoding

General improvements ⊡ Bug fixes, code cleaning, performance improvements ⊡ Updated dependencies

▼ NOTE Nvidia GPUs optimizations ⊡ Is essential to enable Windows Hardware Accelerated GPU scheduling option ⊡ This option can dramatically improve upscale performance ⊡ Enable it in Windows 10 / Windows 11 settings > Graphic Settings menu
