Take a look at how people review Acrok Blu-ray Ripper and 4K Video Converter.

My original file was an H.265 MKV file. My purpose was to work on it with DaVinci Resolve 17 in macOS Big Sur. Used Acrok Video Converter Ultimate for Mac and transcoded the file to H.264 MOV. Fast conversion speed and excellent video quality!

This 4K Video Converter runs on a pretty high amount of system resources and quickly finishes an encoding job without causing us any difficulties along the way. The image and sound are maintained at a very good quality in the output files. I highly recommend this tool to all users.

Tjoar, Oscar

Everything is easy about Acrok Blu-ray ripping software. Download was simple and installation fast and smooth. Converting 4K MXF and MP4 video files was faster than I expected and the new file very easy to find. I love this fast and easy software.
