How to make 100% avi in Pinnacle Studio

[gumpec]

Is there possible to cut one part of avi file, captured from DVcam with Pinnacle Studio. I want only to copy this part - so that I can keep 100% quality and size! If I want to make avi file with Pinnacle Studio, it made it with rendering, not copying!

Try VirtualDub with video compression set to Direct Stream.

Thank's for your answer, I'll try. But is such a possibility also in Pinnacle Studio?

I fired up Pinnacle Studio 8, imported a DV-AVI file, cut it in the editor then output this way

Make Movie
AVI - under settings, make sure "include video" is checked, and also DV Video Encoder is selected.
Create AVI file

Now you have your DV-AVI file at 720x480 normal size.

Yes, thats true. But there is a problem. If you selected DV Video Encoder (always if you choose "same as project") Studio needs some rendering. That means the size is corect (no compression) and the size is allways the same. But the content is always different ! I made the same project from the same avi file but the content was always different (I use compare with CD check - bit to bit comparision. So it goes for new file, not just copy the old one!

[edDV]

Well, losses will be minimal. No other way to do it with Studio 8 that I can see.

[gumpec]

If I understand corectly - there is no way to make new avi file in Studio 8 (or 9?) without any loss of qualitiy. And the best solution will be Virtual Dub - Direct stream - (direct copy)?!

[mats.hogberg]

I'm sure there are many ways, but for simple, free, lossless cutting of AVI files, not many that beats VirtualDub.

OK, so it was different (meaning rerendered) but did that make it any worse or unusable? Any video file after editing has to be rerendered to some degree to rebuild the header and scan/rebuild the internal structure. This is not a zip file... it has its own very specific identity.
Don't know what is what you are looking for so please make it more clear...

[gumpec]

Yes, thanks Proxy99. I want only to cut one part original avi file, captured from my camera - so that will fit on 4.7 DVD. I want to preserve it so much like original on tape as possible. I need it for back up and to eidt such files later (it's easyer to put DVD on computer than connect camera... ). So copy without rendering will be better.

[proxyx99]

OK, Studio 8/9 DV rendering is nondestructive (copied) but the whole file has to be reencoded. The only truly rerendered parts are the ones with transitions. Any editor (like Vegas) will rerender the whole DV file after editing and that is normal. You can use VirtualDub if you are still suspicious and compare the output (should be exactly the same quality as the original in both apps). Takes several renders to make it visible depending on the codec (2-3 renders are usually very safe with zero impact on quality). Otherwise, capture only the parts you want to keep (using software camera controls) and save the files (even in separate chunks) on a DATA DVD for future edits.

[gumpec]

O.K. but why the structure of file, made with the same program (PS8) from the same original file, was different? There war no transitions, no editing at all!

[proxyx99]

That I can't comment on, but whatever was said earlier should address your problem adequately I think. If your concern was quality loss, all I can say is get over it; miniDV is very robust (due to low compression level as compared with typical MPEG2) and you'd need a lot more then 1 edit you plan to do to affect the quality.

[edDV]

If you are that concerned, go back and transfer the DV material in 20min chunks ~ 4.35 GB or 3x DVD to a 1 hr DV tape.

I find I can edit out 20-35% as junk for a typical camera tape. I only archive the good stuff. I also use DV tape for tmp archive rather than DVD. That way I can semi-automate the backup process.

Later I will transfer these tapes to Blu-Ray DVD for long term archive.

I'm not sure just what it is you are saying. Are you saying that after you load any AVI you captured from a camera and cut out a piece or whatever, you then save back to AVI which creates a new copy of it, it is them diferent ? How are you determining that it is indeed diferent. Does it look diferent? Can you see a drop in quality? I'm trying to be critical. I am one of the few who has been able to use Studio successfully without any of the problems widely reported by many. Maybe I'm lucky.
So please elighten me as what it is you need to achieve. Is it s bit for bit copy? I don't think you can do that with studio.

[gumpec]

Yes! I want to do bit to bit copy! Simply that! If I use Virtual Dub, Direct Stream Copy, how can I do it. I try, but the result was different (original and new file).
