We use studio quality encoders for each format (DVD, Blu-ray, online). Studio encoders offer infinitely more controls to fine-tune the encoding which we have dialed in with precision to achieve maximum quality for the bitrate and type of content. Another major factor impacting quality for the DVD is the downscaling algorithm used, which we have spent extensive time optimizing using the most advanced AVIsynth plugins with spline scaling and FFT3D denoise filtering. Basically it will never look better than it does after we process it. Because of this, our DVD processing takes a little longer than it would with Apple Compressor or Adobe Media Encoder.
