alright, followed the guide and it works.
I took an entire episode which I had a script for already encoded it w/picvideo mjpeg.
made a project with proper settings
imported the low-quality avi
saved and made a duplicate of the project.
moved the avi and opened premiere, re-linked
after that worked I exported a section of the timeline (using the .avs)
I then re-linked the low-quality avi and cut it into random size chunks and randomly placed them on the timeline.
unlinked then re-linked the avs again
all my clips remained the same.
exported and did a quick comparison to make sure.
to un-link/re-link in premiere pro you right click the video file in the bin
about halfway through your options you see "link media" and "unlink media"
one of the two should be greyed out
when you click unlink media, an option window pops up asking if the media should remain on the disk or be deleted, I chose that the media remained on the disk.
then the clip(s) that were made with that file go to "media offline"
right click the same video file in the bin and choose link media, and link it to the avs script.
video comes back
I didn't test it with the premiere plugin in the amvapp beta (didn't get the amvapp beta, in the middle of a project)
I'm using
this plugin for premiere pro
cpu: Athlon 64 3200 (2.0ghz, up to SSE2 instruction set)
footage was IVTC-ed using TFM and TDecimate (720x480, PAR 0.9, 24.00fps)
I did not change the colorspace to rgb24 or rgb32 (left it in yv12)
