If you're attempting to encode Photo-pans or other extremely slow moving footage in MegaPEG Pro, we have discovered a bug in the product. The workaround is to use "Fast & Good" on the Speed vs. Quality slider. This setting is also performing very well for 1920x1080 frame sizes. I am getting about 11:1 encoding time for 1080p 24fps using this setting and the results look identical to the source material. As always, for specific encoding questions, please contact us.
