@Kurtnoise13
thanks for the feedback I will retest on my next encode this week and confirm the behaviour in the bug report - unfortunately, when I saw the entry in the job files, I manually cleared-out the FilesToDelete sections before invoking the jobs this time around!! |

When the new b frames decision is implemented into the SVN and is on all the time will there be some kind of notice for us MeGUI users? I still often use bframes 16 and I imagine it would be a bad surprise to find it moving at a crawl in the morning after an entire night of encoding.

Hello sharktooth, and gang! I asked this on the staxrip thread but I have the same problem with megui that has perplexed me a little, hopefully I can get some insight.
I used megui to encode some videos that I intend to be streamed over the web using the wowza streaming server. I encoded the videos using x264 unrestricted 2pass insane quality (200 bitrate)and Im very pleased with the filesize/quality! The problem is there are large delays when seeking to parts of the video and playing it. I also used ffmpegx on osx to encode the same videos, they have an option in there to have a "constant bitrate" but even at a bitrate of 200 the filesize is much bigger. The good thing is it seeks much faster and performs better on the streaming server. The question I have is, how can I encode using megui to have the highest quality, lowest filesize and yet keep it performing great on a streaming server? I couldnt find a "constant bitrate" option in megui, is there something like this, and would it do the trick? Thanks for the amazing work you guys are doing! - Riki |

Part of the problem is that you used the craziest profile in the collection. Sure you are going to get the greatest quality, but for streaming, it is better to use weaker profiles, as they can allow faster seeking.
As to the constant bitrate option, don't worry about it. Using the 2 pass profiles will always give you better quality at a the same file size. Meaning that you can decrease the bitrate safely for a smaller filesize and still have decent quality. Try experimenting with other profiles, such as the DXVA, or standalone profiles, as they are a little more realistic in their settings with respect to the streaming setting vs the Insane profile. They may also improve seeking. If you want to decrease file size, then keep decreasing the bitrate. |

you may want a fixed gop lenght (optional), a lower min-keyint (for optimal seeking), only 1 reference frame (for streaming) , few b-frames (b-pyramid disabled...), set the VBV parameters according to the desired streaming speed and buffer (for streaming), a bitrate based encoding mode (2 pass is suggested... still required for optima streaming) and some other limitations i just cant remember right now.

Its just strange, I tried all kinds of different profiles, and also I tried adjusting all of the parameters you mention Sharktooth, but there is still an unexceptionable delay when seeking and playing the video.
Has anyone tried ffmpegx and know why it would be able to handle this so much better? In the ffmpegx settings I basically just check all the boxes seen here: (only 2 are checked here but I check em all! also 2-pass isnt greyed out for me when I do this) http://www.ffmpegx.com/options.html#x264 I also change the ME to exhaustive and the AVC level to 4.1. I leave everything else alone except of course the bitrate is set to 200. Thanks for helping me with this! Last edited by Riki; 30th August 2008 at 05:17. |

MeGUI Error for 0.3.0.2008
I just reinstalled everything on my computer and updated my version of meGUI to that mentioned in the title. Up to this point I have never had any issues with MeGUI, but now am getting some strange error messages. Any help would be greatly appreciate it.
I leave AviSynth as default, make my selection for the iPOD Level 1.3 profile and CTAAC-128Kbps for Audio. I select the container type as MP4, etc, etc. I click the Queue tab and click Start. About 5 minutes later, after noticing the DGIndex is trying to start, the log shows the following information, the the first fatal error screen, followed by the MeGUI has encountered a problem screen, then everything shuts down. Any ideas? Last edited by divin1ty; 11th January 2009 at 08:54. |
