Doom9's Forum - View Single Post - How much lower of a bit rate on h.265 will give similar quality to h.264?

I've been taking lossless avi files and encoding them in h.264 at 25 mbps for 4k videos. If I make the switch to HEVC, can I really get the same quality as h.264/25mbps at half the bit rate?

Should I do h.265 at also 25 mbps to get the same quality as the h.264 output or would I get similar/equal visual quality with h.265 at a bit rate of 12.5 - 13 mbps? I've been reading these articles saying I should get the same quality as h.264 at about half the bit rate, but is that really true from your observations?
