1 – Generally regarding image quality, it doesn’t matter what tool you use to edit. DV-AVI is an editing format, but it is compressed so that export does equate to 1-generation of loss.
2- Importing into another app will not degrade the image. However, exporting into a compressed format will equate to an additional generation of loss. Exporting as Uncompressed will not cause a loss of visual quality, but it will eat up a huge chunk of disk space. There are visually lossless codecs available that will allow for smaller files.
‘Improving’ digital footage is a very objective process. It depends on what you mean.
3- The ‘Best’ export settings are also subjective. Ideally you should export into the format that you will be using for delivery or archive.
Generally you’ll want to export with 2-Pass VBR with bitrate settings that are the highest that you or your medium are willing to accept.
It’s a good practice to do some compression/export tests with a small 1-minute clip before encoding a large project, using different bitrate settings.
I haven’t used a very recent version of Premiere yet, so maybe something has changed, but your project settings should equal the desired encoding format. So if you need two versions, you would have two projects. You would import your ‘final’ project (not he export, but the actual Premiere project file) into this second project.
Do all of your encodes/exports now, while the project is on your drive, before dumping or archiving your source files, so you don’t have to reload your source files at some later time.
Just some ideas.
