Sony's Giga Pocket captures in mpeg2 . I was hoping Vegas did too. Thanks for your help theeigloo

just wondeirng if you capture in mpeg2, edit your footage and then render to mpeg2 for DVD. Is there going to be more of a drop in quality then if you captured in .avi, since mpeg is already compressed.

Lull, please tell me why you would want to capture, and I'm presuming, then go ahead and edit in MPEG? Apart from the file size, what's the advantage? - I've seen similar posts before and felt too silly in asking the question. Now that I've got "some" expereince under my belt with capturing and editing in AVI - oh yes massive files - what is it that MPEG can give you in the edit?

I'd also like to know if there is a detrimental/artifact effect that editing in MPEG wil give you - that AVI wont?

. . hmmm . .

Grazie

I am not sure of your question. (Exact copy of VHS) But I capture at the Mpeg2 so I can go straight to DVD architect add my chapter points and scene selection, when you click the optimized the only thing getting commpressed is the audio of the mpeg2 video

Grazie Its an exact copy of VHS. I am not editing

Lull - understood! Got it! Well . . .I wonder if I could have my ACEDVio convert to AVI and thence via some inline MPEG s/w that would produce an MPEG2. I know my simple U-Lead MovieFactory DVD authoring s/w will produce an MPEG from most stuff . . I was just wondering if this could also be employed to use a straight VHS>AV<>MPEG>DVD authoring package - that is, cut out Vegas completely? . . hmmm .. intresting . . betcha someone's got an efficient approach to this . . I'm listening . .

Lull, thanks explaning,

Grazie

I'm not really an expert, but what I have gotten from this forum is that mpg (1 or 2) isn't a good format for editing. It is compressed and in a way where a series of frames evolve from a first frame (simplistic explanation but one frame might require previous information) -- avi, though somewhat compressed as we use it, is only compressed on a single frame basis so edits better. As I understand it, if you apply effects to an mpeg it will require re-rendering and may loose significant quality.

I have tried editing mpg source and in my experience -- simple cuts only - the end result wasn't too bad but everything was slower.

So Vegas can handle it to some extent but it isn't recommended. I hear some high end systems can do a decent job. I'm sure others here can give more details, but that's the jist as I know it.

Rex . . I got from Lull that, "Grazie Its an exact copy of VHS. I am not editing" . . BUT it was only by me asking the question that Lull came back with this important piece of info . . and yes MPEG isn't the format of first choice to edit in. But, it was the only way I knew of getting waht Lull was after that I asked the question . .read the thread above . . and you'll get the gist of it - yeah? - Or have I got your response skewed too!?!?

Regards,

Grazie

Ok.

Quick read and I guess I'm still not sure of the real intention of this thread. Guess I read your question as an indication that editing mpg might be ok. It could be but not usually.

Back to the original question -- Vegas can't capture directly from VHS so that's a bit of a confusion factor. Lots of people around here seem to like the Canopus hardware for capturing analog signals to avi and I like mine pretty well.

If you don't edit an mpg, then it is fine as is. For simple cuts I wouldn't worry much either. If I was going to do much (any video effects) I think I would take the hit and convert to avi before editing just for efficiency. That's just my gut feel of the best way to go, but I would defer if others have real experience.

So, Grazie, I think we are saying the same thing now. I just threw more into this that I didn't see in my quick read above.

The reason I asked the question " Whats the Capture format in Vegas?" is becase I am making an exact copy of a VHS no editing and I was wondering if Vegas captured Mpeg2 and theigloo answered that question for me with no

I capture at the Mpeg2 so I can go straight to DVD architect add my chapter points and scene selection, when you click the optimized the only thing getting commpressed is the audio of the mpeg2 video.

Hope this helped
