Have used Compressor to tried to convert to HDV 720p30, AIC, Apple ProRes. Each time: Have settings and destinantion set. Looks good in Preview window. Says: 1 job, 1 target / never submitted. Press sumbit, submit. Get message: Unable to submit to queue – please restart computer or verify your Compressor installation is correct. Have restarted several times. How does one “verify your compressor installation is correct? -reinstall? I’m afraid to ask, because I just bought four HD cameras that are giving me these MP4 video/audio files I want to edit, but is it possible that Compressor can convert to MP4, but not from MP4 to something FCP compatable?
