The best thing about handbreak is that it can be used with almost all formats which makes this software very versatile compared to other similar softwares like VLC player or FFmpeg etc.. It has many functions including but not limited too video conversion (to avi/wmv), audio processing(converting mp3 files into wav file)and screen recording features are its top end options but I think these could have been better in comparison to some free alternatives. So far no complaints as everything just works smoothly without giving me issues so there's nothing much negative here. If you're looking out one such solution where you do not need an expert user then i would suggest using hand brake because they've got most important things right when developing their products. There were times when i wanted to convert my videos at various resolutions but was unable due to different reasons like lack of space storage for large sized media files etc., now.
