Currently, Premiere uses the Lanczos method for intrinsic scale and rotation. Lanczos is an exceptionally high-quality interpolation method which generally yields better results than bicubic, bilinear or nearest neighbor. From reading the forum post, it seems that up-scaling is the real issue here. I suggest looking at the Detail-Preserving Upscale effect in After Effects. It does a really good job and gives you some parameters to tweak to fit your specific content.
Thanks for all the feedback. It’s pretty clear that we’ve got to look into the workflow using this format more closely, there are enough reports about gaps at this point to reopen this item. I’ll post more info about next steps shortly. In the meantime, a couple of questions are easy to answer:
- The plugin is designed for Premiere Pro. It currently doesn’t provide support for After Effects.
- It does work with AME, so if you want to use it for batch processing, that’s very doable
- If you’ve started a project with Autokroma, there’s no easy way to transfer it to be running with the new plugin.
We do monitor User Voice; we share your disappointment that we don’t have a reproducible case, for this issue.
If you can reliably reproduce the ‘low level exception’ problem, on your system, please contact Support and provide them with any files and source media required for that repro case, as well as (important!) step-by-step instructions on how you can reproduce the issue.
We’re eager to pursue the issue further.
