Why does a panoramic video (in an evening or inside a building, shot by Sony HC5E camcorder) look like the frame rate is about 10 fps? My 11-year old JVC VHS-C camcorder never had this problem. Hi Dima, If you are looking at it on a PC, are you sure that the problem isn't that the PC is on the slow side? HDV is quite demanding. If you don't see this effect in normal daylight, or are not using a PC, forget what I said. Cheers, -- Rob Thanks Rob for replying! I don't see this effect in normal daylight and am not using a PC. |

Does the CCD integrate the light over a longer period to compensate, rather than raising the gain. Is it something that is only the case with more recent cameras and the OP's 11-year-old camera which I imagine will also be using a CCD rather than a tube. Is it a switchable setting: low noise at the expense of low frame rate versus normal frame rate at the expense of more noise due to winding up the gain? |

I think most people would prefer noisy pictures than a reduced frame rate. I seems odd that it happens even at normal interior lighting levels inside a house. I can imagine it happening when it's really low light (eg outside at dusk or by moonlight) but not in conditions which will be routinely encountered. |

Don't you just love the level of "customer support" that companies try to get away with these days. Sounds absurd that you can't talk to the technician when the front-line person doesn't have all the answers himself. |

Yes, it sounds absurd that I can't talk to the technician. The front- line personnel does not pass to technicians all the information about the problem which I said to them. The Sony repair shop is located away from the front-line offices. The problem is worsened by automatic switching shutter speed below and above 25 fps during shooting! The switching is noticeable and disturbing! |
