Converting a V7 proj to VP8 - Point of no return

xberk wrote on 9/12/2007, 7:41 PM

Seems like this is easy to do .. my V7 projects open just fine in VP8 but once they are saved under VP8 you are past the point of no return. Proj can no longer be opened in V7. Is that about it ?

Any gotchas that are being discovered?

Yes, that's exactly how it has always worked. An earlier version of Vegas will not open a .VEG saved by a later version.

When you open a Vegas 7 project in Vegas 8, just save it with a new name. Then you always have the old Vegas 7 project to go back to if you need it for some reason.

... or export an EDL from VP8 and import that into V7.

A great idea for emergency recovery. Thank you.

"... or export an EDL from VP8 and import that into V7."

What is an EDL (can't find it in Help or forum search for a definition): I see that "EDL" is a Save As text file option in Vegas, but can it reconstitute as project in the above stated cases?

And since I'm at it, what is the ubiquitous "GOP" term so many use at this board?
Thanks

A "GOP" is a "Group Of Pictures."

One of the ways that encoders such as MPEG2 can compress video information so much is to store just the first frame of a series of frames in a video. Then, rather than storing the second frame as such, it looks for differences from the first frame and stores just the differences, and then does the same thing for the third frame, and so on.

A GOP is the collection of rebuilt frames that have all been used in this fashion. In the NTSC world a GOP is typically 15 frames (1/2 second of video). After that, a new master frame is chosen and succeeding frames reference that one.

This is the reason why a dropout on an HDV tape is so damaging. Lose some data on a DV tape and you get some colored blocks on your video. Lose some data on an HDV tape and your image and audio go dead for 1/2 second.

Thanks for this clear explanation of GOP. Very helpful.

Regards V7 to VP8 -- I think doing a "save as" to preserve the V7 project format is the very best way to go if maintaining a V7 file is needed. .. EDL's are another subject.
