[TEST] Rv9, Divx 51, H.264 R-D Plots

Question: Why are the PSNR values so low? At 3'000 kB/s just 34? Is it not average or overall PSNR? Or am I missing something completely? :confused: .:: Nibor ::.

As for why the PSNR values are so low, consider two things: - The source material is 720x480, pretty much using the entire area. - This sequence is known to be one of the harder sequences to compress The PSNR is the average of all the PSNR's for each frame. As for more metrics, I am not fully convinced they're worth anything yet. :) I will look into some, e.g. SSIM.

For Video I make Test with RV9 EHQ, WMV9, DivX 5.10 and XviD Devapi with PSNR, SSIM and VQM. XviD and DivX are iso-compliant but not RV9 and WMV9. The best codecs are in order: For animates RV9 EHQ crushes everyone WMV9 DivX 5.10 XviD Devapi4 For movies: RV9 EHQ is the best WMV9 DivX 5.10 Slowest 3 pass XviD Devapi4 For Audio The advanced audio codec are very similar for quality exepted MP3. but I make test with audio and for me the best codec are in order: He-AAC 64~96 Vorbis 64~96 MP3Pro 64~96 RA8 Cook 64~96 WMV9 64~96 MP3 VBR 80~128 (with musicmatch jukebox encoder) For Container The best solution for container are: 1) RV9 EHQ / RA8 Cook / MKV 2) XviD Devapi4 / AAC / MP4 Menus integrated with Language and Sub selection but necessary envivio Plugin 3) WMV9 / WMA9 / MKV 4) DivX 5.10 / MP3 VBR / AVI best hardware and software compatibility

@Gaia The mathematical crap as you said it, is not meant to replace subjective tests, but is an addendum to it. There are cases when you just can't watch everything and judge. That's where mathematical video metrics comes into play. You made the right decision to test different codecs on your TV, and pick the best for your eyes, but stop the bashing on video metrics. @Sagittaire We're all glad you told us what is best. Unfortunately, you displayed it as if it was a general truth. Unfortunately, it isn't. RV9 EHQ doesn't crush everyone or whatever. I feel offended when you think so. Some may like the look of it, i personally find it "flat". Keep this in mind when you'll affirm something is "best" in your next post.
