Easy to use, very robust and quite universal video converter. Just nothing to complain... I do use it a lot.

I assume this uses ffmpeg? If that’s so, shouldn’t it be included in its description?

Before I moved to Mac I had no way of recoding video to play better but this app is fantastic. Choose file, select format and WHAM it's done in seconds. Brilliant!

It’s only done in seconds if the job is a simple file change requiring no video format transcoding. Transcoding takes a long time.
