Let me say I'm in the exploring and reading phase to clarify the possibilities that do exist and the practical consequences surrounded ;) Here are a somewhat related information I read in "V1 and FX7 handbook" (S.Mullen, DVC), and my assuming this valid for FX7 as well: "When camera is operating, the EIP generates uncompressed 1440x1080i with a 4:2:2 color space. Digital 4:2:2 data are output via the HDMI port, while 4:2:2 analog is output via component out. Therefore you can record 4.2:2 live HD cideo from the camera without MPEG-2 compression. If you are playing a 1080i HDV tape, the 4:2:0 MPEG-2 is decoded and chroma up-scaled to a 4:2:2. The HDMI chip downscales 1440 to 1280 while it up-scales 540 to 720. The result is 720p which is output via HDMI." ----------- What really looks interesting, except the cost yet, is an external, portable disk like the Sony HVR-DR60 HDV Hard Disk Recorder. I looked through the menues on FX7, but I wasn't able to discover anything related to optional hard disk recording, though I guess it will work as well as for V1. The CityDisk (the second link in my inital post above) is also claimed to be able to record in DV format at the same time as HDV is recorded on tape. Although neither Sony V1 nor FX7 is found among supported camcorders (yet) for the Focus FS-4/Pro HD Portable DTE Recorder, I wonder if the claimed support for native QuickTime HDV 1080i, is a built-in conversion it can do from the received .m2t ? Can Cinelerra possibly utilize this QT format? http://www.focusinfo.com/solutions/catalog.asp?id=3 _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
