Spent a day figuring this out… but I guess it is worth it to make freeware work for you…
When capturing from CamStudio:
Lagarith Lossless Codec (google it and install)
quality 100
playback rate at 30fps
When importing into Premiere:
import footage
right click > interpret footage > ignore alpha channel (I think this is helping…)
When exporting from Premiere:
I had the best compression/quality results using Quicktime HD presets in the Adobe Media Encoder rather than .wma, etc.
I had the best quality export by choosing file > export > movie. under video settings go back to the Lagarith Lossless Codec. this export was flawless for me and just what i needed…
Hope this saves some else’s time!
