When you play a HD video recorded in compact cameras like mine -SD780-, you see a "jump" or so called "judder" every X frames.
I was wondering: Is this an issue of slow writing of frames to the memory? Could be solved by using a faster than 45mb/s SDHC, for example the latest Sandisk Extreme IV? Or there´s nothing we can do to fix it ? Thanks in advance for your help, Regards! |

Usually it is your computer lacking the necessary resources, if you are using a Class 6 card and you see the "judder." Sarah Joyce |

Fastest videos produce Canon 5DMII, 7D, SX10, 550D ... all with 43 Mbps, these are 5.4 MBps !
EVERY class6 card is fast enough! If you want to make dealers or Sandisk rich, buy their overkilling cards - perhaps they send a greeting-holiday-card from Honolulu or Fidji-island. My cheap Transcend class6 cards (8gb, 16gb) write with ~ 10 to 12 MBps. Just for fun I bought a Transcend class10 card (nearly same price like class6), writing with 14.5 - 16 MBps ... total unnecessary. READ speed differs for class4/6/10 only few ... ~ 16 - 18 MBps. WRITE speed of class6 is guarranted to be > 6 MBps. Last edited by DonalDuc; Mar 19, 2010 at 12:22 PM. |

If it does then there might be a problem with the camera or memory card. If the video playback is ok, then it's your computer that is causing it. |
