Smg-uk - If your "short list" is down to those two Bridge Zooms - the choice isn't too difficult.
If your priority need is good HD Video, with Exposure (Brightness) Control and Manual Focus, with very good Zoom Control in Video - the SX30 would be very hard to beat, but without the CHDK 'hack', it doesn't do RAW, or have a large low-compression JPEG, Superfine save mode.
Having used DSLRs, you'd know that P&S cameras aren't nearly as good for Sports and Action shots - but can compensate to some extent if they have a good Fast Continuous mode. The SX30 has a best Continuous mode at 1.3fps - the FZ100 has 11fps at full resolution. The FZ100 video - it does both Full and Std HD levels, is apparently quite adequate, but not as good as the SX30.
If you need choices of ARs (Aspect Ratios) in images - the SX30 is 4:3 AR in all image sizes, but has a separate 16:9 "Wide" mode, slightly narrower than the full resolution image. There is no "DSLR AR" option of 3:2.
The FZ100 does 4:3, 3:2, and 16:9, in all image sizes.
If you need very fast Continuous, Fuji's HS10 (I have one) - does a fastest of 13fps+ at full resolution, and has selectable 7, 5 and 3fps in JPEG, and 5 and 3fps in RAW and RAW+JPEG. It also has a very fast Twist-Zoom for still images - but this is awkward when zooming in Video. It doesn't have Exposure / MF in Video (as does the SX30), either.
The HS10 isn't at its best in Auto and Program modes (where the SX30 does well) - so best images are in the Priorities and Manual, where it's pretty good. It also handles low-light and high-ISO (up to ISO 6400) - better than most P&S Bridge Zooms.
So, for general purposes, it does probably come down to SX30 or FZ100 - and whether your priorities are excellent Video functions, but moderate image quality, minus the high-quality JPEG saving and no RAW (as standard), with very slow Continuous - or the "adequate" Video of the FZ100 - but RAW, good Fast Continuous, and 4:3, 3:2, and 16:9 ARs at all image sizes.
Both the SX30 and FZ100 are reviewed extensively and in great detail, on this Forum ('Reviews', left end of the bar above) - these are the best "pull no punches" Reviews anywhere. So - have a look at those before you decide.
