Rarevision Plugin is a software that is in beta that converts dSLR footage at a quality that is better than using QT or Canon's plug-ins.
Features include
- Raw YUV output option for unprocessed luma channel extraction
- Output luminance matte as an alpha channel (ProRes 4444 only)
- Timecode support: extracts Exif timestamp from THM files
5DtoRGB takes a no-compromise approach to quality, ignoring any concerns about speed. 5DtoRGB bypasses QuickTime decoding altogether, works internally at 10 bits and uses double-precision floating point math for its YUV to RGB conversion. It also recognizes Canon's full range 8 bit YUV values (0-255), avoiding clipping and the resulting loss of picture information. The resulting files are the absolute highest quality you'll ever get out of the camera. In fact, you could argue that they're even better than the camera originals since they've undergone high quality chroma smoothing (which you can disable if you want, but you shouldn't).
There is a free download of the Beta on the page which is limited to 30 seconds of conversion. Just downloaded it and playing with it now...
