This uses many of the same nodes as my image to video (I2V) workflow - and is also designed for lower VRAM GPUs (I use a 12 GB, though I know it also works on an 8 GB with the Q3 GGUF files for Wan 2.2).

General performance sits around ~4-5 minutes for 5-6 seconds of video at 480p (480 x 832). This includes the upscale (2x) to 960 x 1664. Also of note, I tend to save the "raw" 16 frames per second more often than the RIFE + 32 frames per second final save. This is because I like to merge videos - and it is easier to use non-interpolated videos for easier frame management, then add interpolation back in after the fact.

One note that I find is that, likely due to the lower quants, using lighting descriptions is touchy - it can cause pretty substantial lighting fluctuation, especially when running more than 81 (5s) or 97 (6s) frames. One day I'll have enough extra cash to upgrade my PC to support larger faster RAM (not even just VRAM) and I'll get the bigger non-quant models. A guy can dream ...
