If you’re shooting sports the higher the framerate, the smoother the motion will look. Most video clips on the web are either 30P(Actually 29.97), 25p or 24P(Actually 23.98). High end HD cameras can also shoot 50i, 60i, 60P and even higher for slow-motion. I’ve personally yet to see a website deliver streaming video in 60P. . . Most do 30P or less.
As far as what frame rate your FCP sequence should – you said you’ll ultimately be making an NTSC DVD so that means either 29.97 or 23.98. Since its sports I’d go with the higher frame rate 29.97.
However, you left out one important piece of information- you never said whether they shot progressive or interlaced. So that would be the first thing to find out. If its progressive then you’re all set. If it’s interlaced then you’re H.264 clip was actually shot in 60i. Which has a frame rate of 29.97 but gives you 60 interlaced frames per second through the magic of interlacing. Great if you’ll be broadcasting the video but not so great for the web. The web is a Progressive medium. Television has been and still is an interlaced medium for the most part think (Live sports and News) The other clip that’s 25fps could also either be interlaced (50i) or Progressive (25P). So find that out too.
Sascha is also correct in that the avi file will give you problems in FCP. The other MOV file might also give you problems since it was captured with iMovie.
If the shooters can’t recapture and give you files FCP is happy with (MOV) then you could always convert them both NTSC ProRes Mov’s.
The 25Fps clip is Pal so you’ll have to look up how to convert PAL to NTSC using compressor.
Frame size in FCP should be clip based on the clip with the largest size. Then when you transcode the other clips in compressor just scale them up to the proper frame size and frame rate and pro-res codec.
I always work at the highest quality that way when you output for DVD or the web it ultimately looks better. . .
