CHANGELOG 8.0

•  Completely re-designed left bar with more options to select: 
  • "upscaled image/video frame extension" (.png / .jpg)  .png is the best choise for quality, but is slower and upscaled files could be much bigger   .jpg is 10% faster and upscaled files can be lighter but images and videos could have some artifacts

• Support for transparent png images 
•  Rewritten video-frame extraction using multi-thread approach, now much faster 
•  Rewritten video frame resize using multi-thread approach , now much faster
