Edit Ready, Synched Files for Edit

Multi-Channel recording with Ki Pro Ultra 12G provides individual, discrete recordings for each input that are timecode accurate and ready to be imported directly into a multi-channel editing sequence. No additional conversion or software is required, just drag and drop the files directly from the Pak Media into your edit. The clip naming convention is yours to customise to suit your needs, but each multi-channel file is always appended with _1, _2, _3 or _4 matching the input, making it very easy to track assets in post. 

Multi-Channel independent file naming support also allows an independent additional name to be added to each recorded file for further identifying specific information for the project's needs.
