I need any kind of special hardware?< You can transfer DAT files in the digital domain with any digital audio card. Usually the card/deck will use a S/PDIF connection, but you have to check they both use the same type since there are optical and electrical (RCA) versions. You would need some basic audio capture utility that supports the card and which would create WAV, AIFF or QuickTime audio files.(all these can be imported to EditDV) This only transfers the audio (2 channels) and the timecode would need to be transferred separately on an analog interface. You would need suitable hardware/software for this. However, I don't know of any utility that could integrate this timecode with your audio file. If I HAD to do this task, I would transfer the DAT files to a DVCAM tape via an AES/EBU connection and timecode (this would require broadcast style DAT and DVCAM decks). You could then capture the audio from the DVCAM tapes as normal. Perry (give my regards to Halandri) Mitchell Perry Mitchell Video Consultant http://www.perrybits.co.uk OT cantor's diag. arg (was DV software codecs) - "Perry" I'm not a mathematician or much of a theorist, but Kevin Mark's arguments seemed logical but somehow counter normal experience. I think that the answer lies in the fact that pictures that will save losslessly with a higher data size than without the 'compression' will tend to resemble noise, which of course mathematically has the highest information content (Information can be defined as unpredictable content). Fortunately pictures we want are usually rather 'smoother' and ultimately with computer animation can have large tracts of screen space sitting on the same pixel value. These pictures are ideal for run time (lossless) encoding. In general, the whole art of practical compression 'science' is to design codecs where the best compression results happen to coincide with the typical wanted pictures. It is also the reason why there will tend to be a choice of algorithms for different types of material.
