50i will be better than 60i. It's easier to convert (and hence you get better results) 50i to 25p than 60i to 24p. Also, you're therefore shooting using the full 25mbps and keeping most of it for your 25fps, rather than throwing some of it away by recording those 5 extra frames per second for the 60i, that you'd need to remove some how.

"Maker uses motion-weighted resampling methods."
What software is that? |

DVFilm Maker (http://dvfilm.com/maker)
DVFilm Atlantis (http://dvfilm.com/atlantis) also uses motion-weighted resampling to convert PAL to NTSC and NTSC to PAL. The techinique was developed about six years ago for our video to film transfer service. Both applications run on Windows and Mac and can be used with virtually any editing system. |

The FX-1's CineFrame 24 made very well be real 24p, if it's done with the camera's SD mode (as suggested by another member in a different thread). Or is it only the pro model that can shoot in SD?
UPDATE: "CineFrame24 and 30 Mode. This is an attempt by Sony to cater to those independent filmmakers seeking the "film look" with a 24 frames-per-second progressive scan shooting mode. Although the HDR-FX1 does not have a true 24P or 30P filming mode, the CineFrame24 and Cineframe30 modes replicate many of the motion artifacts and the "look" of 24P and 30P, respectively. The CineFrame 24P mode on the HDR-FX1 is enhanced over the 24P effect mode that some users will remember from Sony's DCR-PC350 because it does a 2:3:2:3 pull-down instead of a 2:3:3:2 pull down. When I tested the HDR-FX1's Cineframe24 mode, I did not see the same jerkyness that I found on the DCR-PC350. That is, although any 24P mode will have a certain jitter to it, the DCR-PC350 had an odd "beat" to its jitter that was unnatural. I wasn't able to identify any such "beat" on the HDR-FX1, and the footage looked noticeably better. I think that for the majority of users, the CineFrame24 mode will do a fine job of giving you that 24-frames progressive scan look, while still of course delivering HD resolution -- something the Panasonic AG-DVX100 and the Canon XL2 can't do!" - http://www.camcorderinfo.com/content/Sony-HDR-FX1-First-Impression-Camcorder-Review.htm |

<<<-- Originally posted by Peter Moore : 1080/24p would of course be ideal, but when you go from 60i to 24p you lose a little bit of sharpness. My thought was that that would be made up for by downrezing to 720p. -->>>
I'm curious. How would decreasing the res compensate for a lack of sharpness? |

Lack of resolution and lack of sharpness are essentially the same thing. Downrezzing will not necessarily make the picture look more sharp, but my point is that a slightly unsharpened 1080p (from inverse telecine) might be about equivalent to the sharpness of 720p, so I might as well deliver footage in that latter format since it's half the bandwidth and would look perfect on 720p fixed pixel displays and projectors (whereas virtually no one has 1080p display capability).

Okay. That makes sense.
