* Main Concept H.264, VC-1, MPEG-2
* On2 VP6 Pro * Sorenson H.264 Pro * Sorenson MPEG-4 Pro (for Visual Simple Profiles and Visual Profile encoding) * Sorenson Spark Pro * QuickTime Encoders * Real Media Encoders Don't know what their codec is based on though. |

QT gamma shift "workaround"
Quicktime Pro 7.6.5 on Windows (7.6.6 is known to be buggy) keyframes every 250 best quality (2pass) http://www.mediafire.com/?mjyz3wqttyy Most people don't care for QT, but for anyone interested: one workaround for the dreaded "quicktime gammashift bug" is to use uncompressed avi with the fourcc "IYUV" . There is one that you use for free with "Drastic Codecs" (google it) . For some reason, some other fourcc uncompressed Y'CbCr video can elicit the shift |

Quicktime 7.5.5 Windows encode without gamma shift I made a while back, which comes closer to target file size than previous post. Used same methodology to get uncompressed into Quicktime.
http://www.mediafire.com/file/2ym5yzzugmm/QTPJ.mp4 Settings used: Keyframe: 250 frames Bitrate 14200 Multipass encoding |

Since Quicktime's gamma shift bug is still not fixed and isn't that easy to get around, shouldn't Quicktime be penalised some way in the test? E.g. by leaving the gamma shift in and making the difference clear in the screenshot comparisons. You'd want to bring more awareness of the bug, after all, since it definitely affects quality.

Day 1 noob posting some proprietary encoder results . Xennon encoders are made for live encoding for mobile streaming. They are not optimized for quality only. Since 3gp standard is pretty restrictive only h264 baseline profile is supported :
MPEG4 normal : http://www.mediafire.com/?y2ltdm0y2gw MPEG4 sharp : http://www.mediafire.com/?5vunmrdmzqc X264 : http://www.mediafire.com/?mdyzwyydjhm Thanks for making this collection of encoders. It really helped me make a decision. |

It's not the same, or does your encoder have a INSANE mode

have, but i didn't manage to use it with 2pass RC. Some options are locked for single pass/VBR mode only. Since i aim to target bitrate/size, i use max possible settings for 2pass. Anyway difference between Insane and Ultra is real placebo, and waste of time.

Do you already have a Microsoft Expression Encoder Pro 3 H.264 sample? I don't see one in this thread, so I am working on one myself.
I'm done encoding. For a two-pass encoder, it doesn't do a very good job of maintaining the desired average bitrate. http://www.mediafire.com/?ydgnetqrejo - 17,353,687 bytes Settings Output Format: MP4 Video: H.264 Main Audio: Disabled Mode: VBR Unconstrained Frame Rate: Source Key Frame Interval: 5 seconds Average Bitrate: 15000 Kbps Size Mode: Source Width: 1920 Height: 1080 Video Aspect Ratio: Source Force Square Pixels: Disabled Resize Mode: Letterbox H.264 Settings Complexity: Best (5) Number Of Reference Frames: 15 B-Frame Number: 7 Search Range: 64 Entropy Mode: CABAC ME Partition Level: 4x4 Threads Used: Auto Force 16 pixel dimensions: Disabled In-Loop Filter: Enabled RD Optimization: Enabled Last edited by EricJ2190; 16th June 2010 at 20:01. |

Unless I'm mistaken x264 cannot be held in an mov container. What about Sorenson3 codec? As old as it is, it is sadly still being used a lot of places. Last edited by Guest; 19th June 2010 at 03:49. Reason: 4 |
