3 weeks ago▼ NEW
AI multithreading ⊡ Is now possible to upscale multiple video frames simultaneously ⊡ This option can improve video upscaling performance, especially with powerful GPUs ⊡ Can select up to 4 threads (4 frame simultaneously) ⊡ As the number of threads increases, the use of CPU, GPU and RAM memory also increases
Output path ⊡ Is now possible to select upscaled files path ⊡ Default value is "Same path as input file" ⊡ For video upscaling, also temporary video frames files will be saved in the selected path
▼ USER INTERFACE
Load file widget ⊡ New design for loaded files ⊡ Bigger file icons and in line with the original file aspect-ratio ⊡ Multiline file informations
New widgets ⊡ Added "Output path" widget ⊡ Added "AI multithreading" widget
▼ BUGFIX / IMPROVEMENTS
Video upscale improvements ⊡ Updated FFMPEG version to 7.0 (prevalently bugfixes and performance improvements) ⊡ The app will report the % progress when extracting video frames
General improvements ⊡ Updated AI engine ⊡ Bug fixes, code cleaning, performance improvements ⊡ Updated dependencies
