Hey, I am a Mac user. I have tried DumpMedia Video Converter to convert my YouTube videos. It's smooth and it gives me a great experience. In the official site of DumpMedia, you can see Video Downloader and Online Downloader as well. Video Downloader has windows version and Mac version. But for Video Converter, Mac version is available. If you are interested in this tool, go and search DumpMedia on Google.
Hi! I use Wondershare Video Converter Ultimate on MacOS. Convert video - the main, but not the only function of the program. All video conversion tasks are performed in the main program window, in general, the procedure is as follows:Add a video by dragging it to the list or using the add files button;choose the format to convert to on the right side of the program
specify the folder to save in “Output Folder” and click "Convert". Regarding the supported formats, in this video converter you can convert anything and anywhere:
MP4, DivX, AVI, WMV, MOV, 3GP, MKV, H.264 and others. Additionally, you can convert video to MP3 audio files and other formats, which is useful if you need to cut sound from video. For each format, by pressing “Settings” additional settings are available, including frame rate, bit rate, quality and others. Moreover, that additional features during conversion include the ability to combine all the converted videos into one , as well as edit the source clips by launching a simple video editor. Personally I have not any problems with the converted during its 1 year usage.
Hope I have helped you)
