I am currently processing some MKV files with Submerge using Perian and the Turbo 264. VisualHub will process these files without proper subtitles at roughly 23fps using just ffmpeg. Submerge using Quicktime decoding with the Turbo 264 dedicated hardware encoder is getting just 5fps. (Note: 3 - 5fps is the speed without the Turbo 264 too. The system CPU just bogs down completely.) Mac Mini 1.83 GHz, 4GB ram running 10.5.5. Is there anything I can do to speed this up? Perian 1.1.1, Turbo 264 software 1.3, Submerge 1.5.5 and the latest Quicktime Pro are all installed.
