Especially if you get into tuning down the RF quality a bit (by going with a higher number).īehind the scenes, the speed slider tells ffmpeg to either use or ignore certain types of compression opportunities that requires more CPU resources. I've been doing a lot of 1080p compression and I notice a major difference between veryfast and veryslow. I have studied the results vs the source files in-depth, and I cannot find any substantial difference in video quality.Īgain, I hope this post helps someone out there who is trying to accomplish a similar goal. One 4K REMUX with heavy motion only compressed from 70GB to 52GB. File size does correlate with heavy motion sequences it appears that's where the file size saving is the least. In one case, I was also able to compress a 50GB REMUX down to 11 GB. Generally the file size savings is 50% or higher. With these settings, it takes about 3 hours to fully encode a movie. My hardware is an Intel 16 core / 32 thread processor. (Assuming the source media is HDR): H265 10-bit ![]() My goal is, and always has been, to reduce the 4k REMUX file size so that is as small as possible, but yet retains the image as close to the source-quality as possible, as viewed on my 65" Sony Bravia XBR65850 TV. I have spent a monstrous amount of time on this over the past few weeks (thanks to all the similar posts that i have read, as you helped me get to where I am.) I believe I have found the "sweet spot" for H265 encoding, and I hope this post can help others obtain the same goal without having to do all the intense research I did.
