Tool for grading blurry images before compiling to animate

Hi all, I was wondering if anyone knows of a better way to analyze and grade about 450 tiff files for blurriness. I'm currently reviewing them in pixinsight Blink, and then removing about 5% of the blurred images, before pushing them to photoshop to create a video animation. 

But it's a pretty tedious process. Anyone have an idea on a way to automate that? (remove the worst 5% based on blur, or at least identify them so I can move those images to another folder)

thanks and CS!

You can use Pixinsight's SubframeSelector Process and set a low threshold for FWHM (which is a measure of the size or blurriness of the stars detected in your image). This will let you export only the files that pass the threshold. 

Edit: This only applies to fields with stellar or point source data, this will not work for extended objects like planets, the moon, etc.

I agree, this is a useful tool. I only wish it was incorporated into WBPP in a way so that you could actually limit the frames and stack all in one go. I find the necessity to perhaps export thousands of frames tedious and don't see why we have to do so, at least we should be able to delete bad files from within the process itself.
