small application, somewhat slow encodes, limited number of features.
Highest quality mp4 video output anywhere.
Compared to other encoders, xvid reigns supreme in quality. File sizes 30% smaller than same quality elsewhere. The denoise, scaling, auto-deinterlacing, and the YUV pipeline make for spectacular video encodes.
The ability to crop and scale the viewing frame is the best implementation available. Encodes best with a quantizer setting, letting the encoder adjust bitrate to maintain quality. Doesn't effectively leverage multiple CPU's, so I sometimes run 2 copies simultaneously. Doesn't remember preferences. Doesn't preview encode of video or audio.
Could use more audio preview, video encode preview, audio leveling controls, brightness/contrast prefilters, chronological cropping, and time marked bitrate changes. But these can also be done elsewhere. This quality of video encode I have not been able to replicate elsewhere.
