Converted AVCHD to Prores, now I need to hand over to iMovie

i used log , transfer first time yesterday. supposed edit 1 video footage there others still edited other people, using imovie. unfortunately, didn't know clone sd card beforehand. had delete backup of sd card free space (20 gigs of avchd become 150 gigs of prores leading me frantically deleting stuff laptop!) , has since been formatted.

1. best codec me convert prores files to, other editor can them imovie without hassle (quality not of issue size given on faces when said there 150 gigs of footage)? thinking photo jpeg keep reading aic. i've never used imovie.

2. there way can batch convert them or have each file individually?

3. still have old backup of card (not clone) 30 of 43 clips on it. assuming can identify right 13 clips prores, , convert them useable (as suggested in 1), hassle novice editing friends of footage .mts files , other 13 in aic/photo jpeg/whatever, or of them in aic/photo jpeg/whatever?

 

1. apple intermediate codec (aic)
2. mpeg streamclip , batch list (cmd+b).
3. you, don't seem interested in quality, give them transcoded media.

btw, have backup of media files, in case?
