Me and my fellows shot videos by Canon XF 100, which output video format is MXF. In order to import our videos in Sony Movie Studio Platinum video editor, those videos had to be converted. So that we can do some edits and then upload to our channel. The truth is , I had been using open source Handbrake, but it did some bad conversion. Then I did a Net search, found your Pavtube MXF Converter, tested it, then purchased a license. It worked great and imported to the video editor without any problem. The converted video itself was played smoothly. I am so happy with the result.
