| How can I increase the encoding speed at RipBot 264 ??
What about < LOW priority > box ? Should I check or un-check it ??? Or there is another possibility ??? THANKS !! |

| Uncheckmark it
Newer PC, more cores, overclock (If your listed specs are correct, an i7 at stock speeds will be ~8-12x faster on most sources) Lower quality settings Fewer filters |

Pls , be more explicit , not so laconic , coz I didn't understand anything :( One of my PC's has the following configuration : 
and this is an old one : 
anyway , I use both |

| Please ask a specfic question for clarification then. What specifically didn't you understand? I can't read minds :P
The 1st comptuer will be much faster than the 2nd |

| What's your average encoding time of RipBot? What format/settings are you using?
It takes my quad core @ 3.4Ghz about 5 - 6 hours to convert a decrypted BD from my hard drive to a two pass MKV, 8150MB size. If you factor in the AnyDVD decryption time, that can also add up to an hour. It's a slow process that is dealing with huge amounts of data. It does take lots of time. :( And you are stuck with two pass if you want a certain target size. Check your Task Manager. It should be running all CPU cores at 100% during the encodes. Outside of using a faster CPU or more cores, it won't get much faster. When I used a 2.6Ghz CPU, the same operations as above took about an hour longer. I run most encodes overnight, so the time doesn't really matter to me. |

Using the slower PC my average encoding time to convert a decrypted BD of a 20 GB movie , is 10-13 hours...I'll try on the other one , quad core . I usualy set for 1280/720 and 2 GB. @poisondeathray [quote=poisondeathray]Uncheckmark it Lower quality settings Fewer filters [/quote] Regarding the above answer , pls , give me more details...I don't understand the word = Uncheckmark it and the other senses used in the phrase.... Shortly : I want to accelerate the encodind processeses - which are the necessary setting ?? If the power stops , what should I do to restart the processes , such a resume , if possible.... |

| You asked about low priority box, so I said uncheckmark the box. Low priority means less CPU gets allocated to encoding (other processes have higher priority) = slower encoding if checkmarked
Lower quality settings means less CPU usage required for analysis of frames, so faster encoding. There is far to much to discuss how each setting works or the cost/speed benefit analysis. Lower quality settings will negative impact quality but increase encoding speed. There is a trade off and it's up to you to decide what is "acceptable". You can start here http://mewiki.project357.com/wiki/X264_Settings Filters e.g. avisynth filters need CPU usage as well, so less is allocated to encoding. E.g. resize filters, color correction, denoising. Any filter will slow down the encode. So using NO filters is always the fastest. You cannot resume interrupted encodes. |

| I bought the same cpu for my mother last spring but I overclocked it immediately to 2.8 Ghz (FSB 400Mhzx7) . No need to raise voltage :) Stock fan and only 72 C during Intel Linpack x64 test! (stability test even better that Prime95MT). If I were you I would also stopped using 2-pass and used just single pass CRF@22. Bitrate will be adjusted automatically based on movie content (size variable). Encoding every movie to 2GB is very stupid because every movie is different.
If you select low priority then x264 encoder will get the idle priority otherwise priority will be set to normal. Imagine that your game/program uses 75% of your CPU. If low priority is selected then only remaining 25% will assigned for x264 encoder. This is very useful if you want decent framerate in games during conversion. However if you leave 'Low priority' unchecked then both game and encoder will get equally 50%. |

| Thanks for answers, @poisondeathray and @Atak_Snajpera
....but you've lost in details and I'm , frankly, not interested in the mechanisms of encoding ... I just want it to work faster and if possible, maintaining the quality. So: If I uncheck that box I'll have a lower speed, and if I leave the <LOW PRIORITY> box checked , it will be higher encoding speed ,am I right? Thanks !!! Hope I'll be right ;-) :D:) |

Read again what i wrote. In most cases speed will be the same. |

| To all who use software RipBot264:
If you try to encode some defective films, protected or having other disparities, DO NOT Uncheckmark the <LOW PRIORITY> box ,because that will block the process of encoding and conducting to failure. Only if <Low priority> box is checkmarked, then the software will work at full capacity and will run easily over any flaws, unlike MeGui stops in these points.. |
