Cqmatic for smartphone encoding?
Kwag,
I was wondering if there was any way I could set up cqmatic to calculate the cq for certain size memory cards. Using the custom settings in calcumatic I can get the bitrates, but that is as far as I can get. I tried cqmatic for the hell of it but I get a "invalid resolution" error since I'm using 224x176. Any ideas how I can get this jewel to do the job? Thanks Magnus |
Hi magnus,
Get me the smartphone available resolutions, and I'll modify CQMatic to include them :!: Is 224x176 the only one used :?: -kwag |
Kwag,
You are the man! I have seen just a few resolutions listed: 224x176, 240x176, 176x136, & 220x176. There may be more but this is all I know of. Will I need to do anything differently in cqmatic from what I am used to with my other encodings? Thanks again for your help and thanks for all the great work you put into this site! Just think, I remember when you presented the idea of kvcd to the conversion community (vcdhelp etc.) and many said it was impossible. Hah!! Job well done! Magnus |

After a little research, I've found that the four standard resolutions used on smartphones, are: 160x120 176x220 208x240 240x320 Sadly, 176x220 can't be used with TMPEG, because 220 can't be evenly divided by 8. So TMPEG will bomb with an error if you try that resolution. So I just included the three other resolutions, except 176x20. Quote:

Let me know how the new version works. Remember, you are encoding at small resolutions, so you should use CQ_VBR instead of CQ :!: -kwag |
Kwag,
I hate to ask but could you please add 224x176. I have tried it and it works perfectly on my phone. Also, I plan on using your template you created a while back. Do you still feel it is the best settings, gop etc. for smartphone encoding? Thanks again Magnus |

http://www.kvcd.net/CQMatic-1.2.06.exe Edit: BTW Magnus, remember to set your MIN bitrate to 0 and your MAX to ~300Kbps. You shouldn't need anything higher, for such a small screen. -kwag |

What would you class as a small resolution, as I've always used CQ so far. If CQ_VBR would give better results as lower res, I'd like to give it a try :) |
So little resolutions CQ_VBR is much better than CQ . Use it with resolutions at 352x288 and all values under this.
@kwag In TMPGEnc out of standart SVCD Template I can use 240x576 as resoltion. Is this resolution also integrate? |

Excuse the dumb question :oops:
What's a Smartphone :?: |

Which usually integrates a PDA type screen and now they also have a small camera that let's you take a picture and send it over to another smartphone while you are talking. Plus many more features, depending on the manufacturer. Have you seen the Verizon commercial of: "Can you hear me now?" :?: Well, you'll soon be seeing new commercials like: "Can you SEE me now?" :lol: :hihi: -kwag |

Sorry to go off topic but, why is CQ_VBR better than CQ at low res. :? |

Perhaps some Player doesn't exept 352x576 and perhaps the Movie doesn't fit in htis resolution on a CD-R. So I have this questions if this resolution is integrate because it's also as an non-standart template in TMPGEnc. I don't mean smartphone. |

The smallest (widest) resolution that I have seen supported on standalone players is 320x, but not 240. Most players will display this as a "squeezed" video on the screen. -kwag |

Greatly appreciated! Last question, should I leave the gop and other settings the same in the old template. I'm not sure if you created this template before the new matrix and gop settings. Thanks Magnus |

But it was a try. :wink: |

You might even want to decrease the frame rate by half, and don't forget to encode your audio at 64Kbps. :idea: That will now fit just about any 2+ hour movie in a 128MB flash card :hihi: -kwag |
