Hello I am having a problem loading some .MOV files (but not all), through enabling Quicktime plug-in I can view some .MOV files but not others.., i've tried some codec packs including installing Apple Quicktime with depreciating features ticked but no luck., is there any codecs I can use to sort this..? Previously all .MOV files would play but now not files I purchased at Shutterstock.., these files now show in Vegas as blue thumbnails with a clapperboard in the middle.., I can not use these in the timeline. I don't want to change the files to MP4 files because I think some detail and clarity in the file is lost through compression., do they have to be compressed..? Thanks in advance, any help is greatly appreciated.
