If you're encoding, this is the command line in staxrip that apparently gave the best results. The A380 cards are now reasonably inexpensive - low enough to justify an experiment - but if anybody has this hardware combo and has previously experimented with hevc/hyper-encode/handbrake - please let me know the results ! So the next question is on the hardware to do the h264>h265 conversions - I'll be using the qsv_hevc encoder on my 12700K, but I'm also interested in pairing it with an A380 using intels 'deeplink' technology, allowing parallel encodes (dgpu + igpu) - reporting a 65% reduction in encoding seem to recall you having an A380 - did you ever explore 'hyper-encode' in Handbrake for hevc encoding ? I'd rather convert to a well supported but older codec than opt for a potentially risky codec that may be beaten by h266. So I've been stalling the decision on what codec to use to replace all my h264 - I've come to the decision to just use hevc/h265, rather than AV1, as it seems to be a much slower takeup than I thought it would be and hardware decode support is still lacking.
