Poorly written, delusional pricing, deceitful marketing — a halfassed port of old Windows rubbish. Seriously, this is pure junk.
Don’t believe a single consonant uttered by this “developer” (a laughable term in this context). Even if you ignore his −4 rating, he’s a bloviating scammer chock full of marketing-speak who has never actually addressed (let alone fixed) anyone’s problems.
There are literally dozens of FREE converters/transcoders available that are vastly superior to this lump, including some that actually work. For instance, HandBrake, MPEG Streamclip, Hybrid, Burn, ffmpegX, Adapter, MakeMKV, VisualHub, Media Converter, remux, even VLC is more capable than this POS. Then there are the many $8-$30 FFmpeg front-end apps, like iFFmpeg (my favorite), VidConvert, etc. Anything (including nothing) is better than SproutConverter.
Shame on MacUpdate.com for posting such dreck.
