Name of comparison | Type of comparison | Date(s) of publication | List of compared codecs | Comments |
---|---|---|---|---|
Series of Doom9 codec comparisons | Series of subjective comparison of popular codecs |
|
|
Subjective comparison with convenient visualization |
Series of MSU annual H.264 codecs comparisons | Series of objective H.264 codecs comparisons with MPEG-4 ASP reference |
|
|
Detailed objective comparisons |
Series of Lossless Video Codecs Comparison | Two size and time comparisons of lossless codecs (with lossless checking) |
|
|
in 2007 — more detailed report with new codecs including first standard H.264 (x264) |
MSU MPEG-4 codecs comparison | Objective comparison of MPEG-4 codecs |
|
DivX 5.2.1, DivX 4.12, DivX 3.22, MS MPEG-4 3688 v3, XviD 1.0.3, 3ivx D4 4.5.1, OpenDivX 0.3 | Different versions of DivX was also compared. The Xvid results may be erroneous, as deblocking was disabled for it while used for DivX. |
Subjective Comparison of Modern Video Codecs | Scientifically accurate subjective comparison using 50 experts and SAMVIQ methodology |
|
DivX 6.0, Xvid 1.1.0, x264, WMV 9.0 (2 bitrates for every codec) | PSNR via VQM via SSIM comparison was also done |
MPEG-2 Video Decoders Comparison | Objective MPEG-2 Decoders comparison |
|
bitcontrol MPEG-2 Video Decoder, DScaler MPEG2 Video Decoder, Elecard MPEG-2 Video Decoder, ffdshow MPEG-4 Video Decoder (libavcodec), InterVideo Video Decoder, Ligos MPEG Video Decoder, MainConcept MPEG Video Decoder, Pinnacle MPEG-2 Decoder | Objectly tested (100 times per stream) decoders "crash test" (test on damaged stream — like scratched DVD or satellite samples) |
Codecs comparison | Personal subjective opinion |
|
3ivx, Avid AVI 2.02, Cinepak, DivX 3.11, DivX 4.12, DivX 5.0.2, DV, Huffyuv, Indeo 3.2, Indeo 4.4, Indeo 5.10, Microsoft MPEG-4 v1, Microsoft MPEG-4 v2, Microsoft RLE, Microsoft Video 1, XviD, 3ivx, Animation, Blackmagic 10-bit, Blackmagic 8-bit, Cinepak, DV, H.261, H.263, Motion-JPEG, MPEG-4 Video, PNG, Sorenson Video, Sorenson Video 3 | Sometimes comparison is short (up to one text line per codec) |
Evaluation of Dirac and Theora | Scientific paper |
|
Dirac, Dirac Pro, Theora I, H.264, Motion JPEG2000 (the tested codecs are from Q2-2008) | Quite detailed comparison of software available in Q2-2008; However, a buggy version of ffmpeg2Theora was used |
VP8 versus x264 | Objective and subjective quality comparison of VP8 and x264 |
|
VP8, x264 | VQM, SSIM and PSNR for 19 CIF video clips with bit-rates of 100, 200, 500 and 1000 kbit/s |

Famous quotes containing the words freely and/or comparisons:
“The proclamation and repetition of first principles is a constant feature of life in our democracy. Active adherence to these principles, however, has always been considered un-American. We recipients of the boon of liberty have always been ready, when faced with discomfort, to discard any and all first principles of liberty, and, further, to indict those who do not freely join with us in happily arrogating those principles.”
—David Mamet (b. 1947)
“The surest route to breeding jealousy is to compare. Since jealousy comes from feeling less than another, comparisons only fan the fires.”
—Dorothy Corkville Briggs (20th century)
