Importing Preset not working correctly for exporting clips from timeline as separate files

yeah, all the posts here are correct, but feel free to use the project manager to "consolidate" to a separate drive and then unmount your original media drive and test the integrity of the "consolidate."  This way, if material is offline, you can manually copy that material over...  Yeah it would be wonderful if this feature would work flawlessly, but no reason why you can't work around it's limitations.

If you have some troubles with the Project Manager, you can give PlumePack a try ! It's a third party Project Management plugin for Premiere Pro. 

The "Collect & Copy" feature of PlumePack is FREE. So no "unknown error", copied footages are organized following the PrPro structure, nested sequences are well taken into account when selecting a main sequence to consolidate, and you have a real detailed analysis/report of what the consolidation will/did to your project and media. So it is definitively a good and hanful tool for PrPro users ! 

If you choose to pay for the Premium License, you unlocks the "Lossless Trim" (without re-encoding) feature. So you saves some space by removing unused frames, but your files keep their exact same quality (no encoding), same codec and metadata !

Until Adobe has made a serious effort to really revamp the Project Manager, I stay miles away from using it. In the past, I have gotten badly burnt relying upon it.

The main problem is that it works only skin-deep. By this I mean that although it does copy over any dynamically AEP files in the archive, it ommits to include any of the assets that were used inside these AEP files. The result may easily translate into you opening an archived project (years later, when the contents of your local drives have changed ten times over), only to find out that the company AI/EPS logo is missing from the AEP file!

As to using the Project Manager to transcode source footage in separate clips, I would simply advise against doing this. Instead, for each project you create, create a separate folder on your hard drive and rigourously copy over all assets used (no exceptions!) in the project. If there is an asset you wish to use in the project, copy it to the project folder before importing it inside the project.

Upon archiving time, simply make two copies of that folder to separate external drives. It may cost you more space, but the cost of hard drives is going down faster than your hourly rate of having to source missing items from an archived project created using the Project Manager.

Hope this helps.
