adobe premier 1.5 capabilities trim/extract

[Dave176]

Wow i am having a hard timewith this program. When I extract and delete a section at the end of of a video, the size of the file doesnt change. Is it not possible to make another copy of the captured video at a smaller size so i can fit it onto a burned dvd? Or can adobe premier pro 1.5 not acutally alter the original capture? This program is so challenging i spend hours and acheive nothing.

Non-Linear Editors are non-destructive. They take you original footage, and record all the changes you want to make to it (edits, transitions etc.) and save this information in a project file. When you are done making your changes, you output a new video, which is the changed version. Your original remains untouched. This is how they are supposed to work, and thankfully how they do work.

What you need to do is slow down, do some reading, find some tutorials, and learn how it works. Premiere (and Vegas, and even more-so, Avid) are complex applications. Coming in to them new and trying to feel your way around blindly is a sure way to waste a lot of time and get really frustrated.

To solve your immediate problem, look in the help files for either Render or Export (Can't remember which term Premiere uses). They are under the File menu. This is where you create your new, edited video.

You need to get a good book or DVD instruction disc like the Total Training series. There are some tutorials online but they only focus on narrow aspects of the program.

There are fundamental concepts to understand. There is the "project format" that you set as a first step. This might be DV or uncompressed YCbCr or uncompressed RGB. Then there are the import formats (many) like say MPeg2. You can preview and trim an MPeg2 file and pull it to the timeline. It will then need to be "rendered" as in "Render the Workspace" under the "Timeline" menu before it can be played from the timeline. Area to render is set by the yellow workspace bar. Unrendered areas are indicated by the orange bars.

Assume a DV project format with a trimmed MPeg2 import file. When you include the the trimmed clip in a render, a DV version of the clip is rendered as a temp file. When the render is complete, the file can be previewed from the timeline along with the other DV or rendered clips.

When all clips have been rendered and previewed to satisfaction, a realtime 1x playback could be made to DV tape (aka "print to tape") or a non-realtime encode could be done to DVD MPeg2 or other formats.

Virtualdub does much the same thing except it works with only one file at a time and it decompresses the file to RGB as the first step.

The basic assumption of Premiere is it will be rendering only a small percentage of the imported clips in the bin. Trims are done as a first step in the imported files native format in order to limit render time and temp file size. Premiere also assumes multiple stacked layers of clips on the timeline. When a render is performed, it is done on all the clips in the vertical stack. Change any clip in the layers and a new render workspace will be required.

The way to speed Premiere up is to work only with project format files like DV or uncompressed YCbCr (e.g. SDI). In those cases workspace renders only are required for transitions, overlays and filters.

So to take your example in a DV format project space, the Mpeg2 file would be imported and trimmed. All that has happened is the trim points are saved. The imported file remains unchanged.

Next you pull the trimmed clip to the timeline and render the workspace. A new DV format tmp file is created for the trimmed clip. Next you export to a DVD MPeg2 file. The temp file is then encoded to a new MPeg2 file. At this point the original file, the temp file and the encoded MPeg2 file all exist on the hard drive.
