Hi, I have a MAC Mini and several DV tapes that I'd like to put on the hard drive without loss of generation/quality. I don't have any special capture cards or anything, just Final Cut Express software. Is it possible to capture my DV's without loss of quality 1:1 from DV to Mac?

Which format should I use? Avi, MPEG? Which is the higher quality format?

BTW, I am capturing from Canon Elura 65.

Thanks a lot

P.S. Also, which non-linear editing softs have color correction option that I could use?

What you have should work fine.

I would simply capture as DV, that's a striaght 1:1 capture. If you import as AVI or MPEG that's when you are compressing the signal.

Thank you. But which is higher quality? MPEG or AVI?

Sorry, I think I misunderstood you. What do you mean by straight DV? What format is that as opposed to AVI or MPEG? How would I be able to edit that?

Others can answer that better than I, but I believe MPEG is a more efficinet compression technology than AVI.

Which means MPEG can reduce the over all data while maintaining a decent picture.

In FC Express in the capture drop menu you should see various video formats for image capture. You should see DV NTSC or DV PAL, choose which ever you need. That will be a straight 1:1 DV capture from a DV tape.

You actually cannot edit MPEG files because MPEG is intented for viewing and not as a video format. You want to edit DV.

You don't have to worry about MPEG or AVI until you export your edited piece. That is when you want to compress the file and make it smaller for viewing.

Let me restate that.

You don't want to edit MPEG because it is very compressed, and a pain to deal with.

You want to edit DV which is a standard video format with real frames.

I'll offer another non-expert opinion.

As far as I know, QuickTime is the native video format on a Mac. The QuickTime video format has several different codecs, some of them are "lossy" (Sorenson, for example), and some are "lossless."

You can read a nice definition of the term "codec" here:

http://en.wikipedia.org/wiki/Codec

Since your source material is MiniDV, the QuickTime DV codec (I think they call it "DV/DVCPRO 25") should capture your video without losing any quality ("lossless"). I believe that this is the default setting for capturing video via FireWire.

No there is no Quicktime DV codec. DV25 is a standard video format that Quicktime supports.

DVC-Pro is a professional DV format (seperate from miniDV) developed by Panasonic, which Quicktime also supports.

Lossless and lossy deal with compression schemes such as MPEG, Sorenson, TIFF and so on.

I stand corrected.

Thanks for clearing that up.
