Sisters of Death (AI Upscale - Dual Audio)

[Fernando_M]

I've done an AI Upscale of Sisters of Death to 720p, and I think the results look better, compared to RiffTrax's version, although it isn't a really dramatic improvement, because of the poor quality of the available source. The file includes the Riff audio, the original movie audio & subtitles:

I used an original DVD copy, which is linked below, in case anyone wants it, or wants to have another go at doing an upscale:

I experimented with different Topaz Enhance AI models, and I got the best results from upscaling to 720p using Proteus Fine Tune v3, with settings of: Revert Compression 81, Recover Details 10, Sharpen 18, Reduce Noise 2, Dehalo 9, Antialias/DeBlur 2, Grain Amount 1.7, Grain Size 0.4.

Before running the Enhance AI model, I removed interlacing effects using one of the AviDemux filters.

The colours of the new version look different compared to the RiffTrax version, because I specified BT.601 NTSC as the colour matrix when creating the final file. I think this is how the movie is actually supposed to look, and the RiffTrax version has an incorrect colour matrix.

Doesn't the dirt seem kind of colorful in the AI screenshot?

The colours in the RiffTrax version looked too "vibrant" to me, for example, the lead actresses' red coat in the shots in her apartment, or the purple interior of the Latino guy's pickup, but I agree that switching the colour matrix to NTSC gives the video a greenish tinting, which is a lot more apparent in outdoor scenes.

I'm happy if someone wants to modify the video or redo the Upscaling and repost a better version.

I'm pretty sure Rifftrax used the VCI DVD as their source because they have done other VCI titles like City of the Dead, The Dark Power, Kiss of the Tarantula, Mikey, and Ruby.  They seem to do a lot of titles from VCI, Multicom, and more recently Vinegar Syndrome.
