Frage von Merowin:
My task: I want to have many DV tapes scattered Rohaufnahmen without quality loss thematically arrange for future film-cutting.
These are the tapes in VDL 2006/2007 imported as. MVD files by topic cut and exported. These files can then be sorted harddrive.
As a DV-AVI I get just under 3.6 MB / s and the required processing time of the PC was 13 MB / s when transferring to external hard drive. Therefore I suspect that the raw data remain unchanged.
As an alternative I have in the export "uncompressed video ..." is selected. Then, the exported file (name, too. AVI) 31 MB / s and the processing time was 16 MB / s. That I do not understand. How can a RAW editing by 8 times as large? More information can not be in it than the original.
If I were the two versions (DV-AVI and Video_unkomprimiert) VDL import again, I can s.Screen no difference. ?
My questions are:
(1) If an exported DV AVI for later processing with VDL as the data equivalent of the original DV tapes?
(2) What is the alternative "" uncompressed video "good?
Thank Merowin

How can a RAW editing by 8 times as large? More information can not be in it than the original. So it seems. For an archive of the same material (simple cuts, extracted clips) makes no sense. DV DV may remain.
Otherwise it looks when you are changing only the material. You change for example, in one step the brightness of the original (eg, dark), missing the next generation gecroppte Helligkeitsinsformation. Since brightness and color describing the pixel
(the information) and the picture in pixels dissolved, there will be any change in inaccurate defined transaction, which is more verpixeltes Picture. The information is presented after the change has become no more, but
absolutely unchanged, relative to the original but significantly diminished. The weaker the compression, the more is still synonymous after several steps (Effects, Color correction, transitions, etc.), your clip "as" new. DV is a violent halt Compression.
