MICHIGANMOTHER  I must be doing something wrong, after reading all the great comments here, but the resolution I am getting when I convert a MPEG1 file from my Sony Cybershot camera to either DV or MPEG4 format is terrible! Video looks fine in Quicktime or in Streamclip viewer before conversion, but I can see individual pixels in converted version in both Quicktime and iMovie. Original file is 640x480, I am using Mac version of Streamclip 1.9.1, and am clipping a 7 minute portion of original video from the file to convert so I can import into iMovie. Using all the preset defaults. Anyone have any ideas?
