A few questions about rendering

Hello, I was wondering about a couple of things. I shot a film with a Canon GL1 in movie mode, meaning it's encoded progressive. Does that mean that it's progressive on the miniDV tape ? When I capture all my clips are progressive (which is cool anyways). I am then wondering, can I print it back to tape as progressive ? So basically my question is, can miniDV tapes record in both interlace and progressive ?

My other question, if I print from the timeline, I will loose less quality then if I render the whole movie as an AVI file ? (I assume that printing from the timeline only renders the transitions so the rest isn't decompressed/compressed/decompressed) Am I right ?

Thanks a bunch,

Nat

Yes, DV can be either. And so can the Vegas project settings. If you haven't, you'll want to set your project for your final output type.
What isn't rendered in a print from timeline session is only a file transfer when rendering a compete AVI DV file.

yes. you can freely change modes and continue recording on the same tape. but if you switch modes in the middle of a clip, Vegas will interpret the clip using the first mode you were in. but that's no problem because you can control how Vegas interprets your clip by right clicking on it and going to properties. there you can change the field order to "progressive" or "lower first".

if your source material is progressive, you should pretty much always render to progressive and whatever playback device will be able to interpret it however it needs to.

can someone fill us in on 60p? is that compatible with DV? where would the extra bandwidth come from?

make sure your source properties match your destination properties and VV3 will not recompress your DV data. if you render interlaced DV as progressive DV, then VV3 will have to recompress. but the SF DV codec is really good about multiple recompressions. according to the tests I saw, it will take perhaps a dozen or more re-renders for you to notice a difference in quality, which is only noticeable by using special filters to compare the original to the recompressed frames.

Thanks for the answer, another question.
How come the progressive information on the miniDV tape plays back well on a TV system which should only read interlaced material ?

Thanks
