The sony trv900 Pscan is 15fps for NTSC and 12fps for PAL. It is too jerky looking.(posted 8521 days ago)If you reduce the shutter speed to 1/30 of your TRV900 while in interlaced mode, you will get a filmlooking take. Only the first field is captured. The seconf field is derived by copying the first one. The frames will be made from two identical fields. The result is more cinematic feel. A side effect when using this feature is reduction of vertical resolution/quality. Most noticable on near horizontal lines. If you like instant filmlooking takes, try it. A PAL TRV900 with shutter speed 1/25 will give better cinematic results becouse its 25 frame rate being closer to film speed and is better suited for film transfer.

If your camera is NTSC shoot interlaced. The transfer company will do the rest.
But remember: when shooting interlaced the resulting film will be with less vertical detail/resolution.
Here is a company for film transfer and tips how to use the Canon XL1 when planing transfer to film:
