New Canon TX-1 Looks Weird

Both will likely still exist separately for a long time, but I can see a growing segment of crossover cameras. Why have two when one will do it all, I am sure, will be the marketing motto. I'm not into shooting lots of video, but I did choose to leave the camcorder at home when I traveled to and worked in Ukraine last summer. I decided that the 30fps VGA video of my little pocket camera was enough for me, since I primarily shoot stills (5D). As it turned out, I actually figure I shot MORE video with it than I would have with my camcorder, simply because I could slip the tiny SD700IS into a pocket, where the camcorder would never have come along anyway. It's not as good as "real" video, but it was very usable for my purposes. There are plenty of folks who are tired of lugging around even the smaller tape-driven video cameras. -- Images (Plus Snaps & Grabs) by MarkČ at: www.pbase.com/markuson |

The 1/1.8" CCD should be at least comparable to the 3x 1/6" CCD's in the current Sony/Pana/whatever lineup. You can always stick yet another digicam in your pocket if you want to also shoot stills. |

Yes, there is definitely going to be a merger of at least some types of still camera and video. i thought it was going inevitable 5 years ago..... hell, my mobile will do 4o minutes of 640x480 @ 30fps! kosh |

To go higher than that they'd have to either split the video across two files or go to NTFS or some other file system on the card, which would, no matter what they chose, introduce compatibility problems. |

But when I watch VGA video blown up to my 1600x1200 screen it still looks fine. You've never seen HD then. After you've seen 1920x1080 HD, SD analog video, no matter how well produced, looks like crap. Frankly I'd rather have a 3ccd hard drive hiDef video camera with the same size sensors :-) 3ccd looks sort of obsolete to me. Larger single CCD's are getting cheaper and cheaper to make, but as the CCD's get larger the prisms and alignment systems for 3ccd systems get ridiculously expensive. So you've got the semipro Sony VX2100 or its HDV successor with 3x 1/3" CCD's at around $2000 and the next model up, with 1/2" CCD's is around $5000. But three 1/3" CCD's is around the same sensor area as 1/1.8". It avoids the light losses in the Bayer sensor but it still doesn't collect anywhere near as many photons as a 4/3" sensor much less an APS-C sensor. The $17,500, 12 MP, super duper Red digital cinema camera will apparently use an APS-C sized sensor but I seriously don't see the obstacle to doing that at the VX2100 price level and HDV resolution. |

I don't see what's wrong with splitting the video or audio into multiple files. Audio recorders do it. Just start a new file every so often. |

I'm sure I could tell the difference, it's that I just don't care. I've seen 70mm film at the theater and I'm sure that looks even better than HD. But the actual experience of watching the movie isn't especially better than watching it on VHS in someone's living room. I really care a lot more about the quality of the script, the acting, whether the person in the next seat is coughing on me, etc., than I do about the pixels. The most successful documentary of all time (Fahrenheit 911) was shot mostly on SD video and I really doubt that anybody minded. |

Is there a standard for doing that or does doing so lock you into a proprietary program for playback? |
