Acrok Video Converter Ultimate is a utility created to help you rip DVDs and Blu-rays, convert videos between various formats, and extract soundtracks from your favorite movies. The application comes with a user-friendly interface, works with many media formats, supports batch conversion, and offers you quality results in no time.
You can import multiple files at the same time, preview them by using the integrated video player, and choose between a wide variety of output profiles. The program also features various video editing options which come in handy if you need to change the resolution of the input movie or extract segments from the imported videos.
Unfortunately, the application comes with several flaws. For starters, it doesn't let you choose individual output formats when batch converting videos. Also, it doesn't offer you support for the SUB format (a popular subtitle format).
Another thing that bothered me was its price. It's a bit too expensive for what it can offer you. You can find plenty of other video converters for Windows PCs that provide you with more useful features and are cheaper than this program.
Hence, I think you should try a different video converter on your Windows PC.
