saving clips lose generation?

[djblackburn]

Hello:

(1) I'm on first project, may be doing this wrong...
I have been taking video clip from library to preview, then cutting it to proper frames, then "save video clip."
I'm worried that I am losing a generation on these clips when I insert them to timeline. Is this so? If so, can I render my show in final form skipping those clips already rendered once?

(2) I'm cutting 48-minute show in 12-minute parts. Now, in Part Four, the program freezes on a segment. I have checked the clip segment separate from the timeline (in preview) and it is fine. But even changing the clip in the timeline does not work. Any ideas?

Thanks, Dan Blackburn

Dan,
You are doing it the hard way by using Save Trimmed Video control, which renders out a new video file each time you use it.

Instead, use the scissors control (or multi-Trim Video) to make cuts in your video while it sits in the timeline. These cuts are virtual - they simply leave pointers in the project file that define the regions of the original capture file that will appear in your final project video file.

You can treat the virtually cut regions just the same as if they were real files - for example, you can delete, add fileters, change audio level, etc. No physical changes are made to your source files. When you create your final video file of the entire project, all the virtual edits are rendered into a new real video file.

If you have a corrupt section of video, try to isolate it into a small region and delete it from the project. Sometimes you might have to "repair" a corrupt file by physically rendering a new copy with smart-render disabled.

I'm still not sure if I lose a generation when I use "save video clip". Can I render a final show and skip re-rendering those clips that have already been rendered?

Sure you can, but you need to not think of this non linear editing tool in analogue terms. The term 'lose a generation' relates back to the reel to reel video tape editing days.

Video studio is a digital editing tool. Think of it this way; If you take a word document and open it and then you cut sections out of it and save your new document under a new name; is your new document of a lesser quality than your original?

That's what you're doing with Video Studio. As long as your 'Save Video' properties are identical to your original file or files, in other words you're saving using the 'same as project properties' setting, you aren't losing any quality. If you inserted the same clip into the timeline 10 times and selected different in and out points and then rendered it as one file, the end result would the same quality as your original clip.

Thanks. I am so impressed by the REALLY helpful info provided by this forum, and by your particular comments -- clear and comprehensible. I have a lot to learn but now am more confident that I can do what I need to do. Dan

I don't want to contradict you, but your answer is not entirely correct. Whilst DV-AVI is only slightly compressed, lossless at that, every time you render this into a new DV-AVI file, this slight compression is applied again. If you do it often enough, your clip will deteriorate. It is best to work like you suggest, not rendering new interim clips.

The OP also asked if he/she can leave out these pre rendered clips from the final render. That is impractical unless the OP intends to render other sections of the video separately also and finally combine all these pre-rendered clips into a complete video. Certainly doing it the hard way if that was true.
