    Jamie, We are no longer in the film era and I don’t think digital projectors use motors except for cooling fans.

    why don’t more camcorders shoot at a true 60 fps instead of 59.97 since most displays refresh at 60 Hz or multiple thereof? This mismatch just results in added or dropped frames when rendering?

    this is chromatic aberration. it's like when a prism separates light into colors. you can't easily correct for it. you can minimize it by keeping the subject of interest close to the center. when a lens is designed for a camera it is corrected in the design of the lens and using software. this is a common problem in teleconverter lenses.

    Gary, I suggest you go to the time point in the merged clip and see if you see a small glitch.

    My response was not as clear as it could have been. Here is a clarification.

     

    This is how to merge video clips.

     

    Go to the folder where you have the clips.

     

    Use SHIFT right click to open the command window.

     

    At the prompt > enter copy /b clip1 + clip2 targetfilename

     

    To enter the clips click and drag them into the command window

     

    Hit enter.

     

    Your target file should appear in your folder

     

    For AVCHD files the extension to use for your target filename is .MTS

    In your editing program extract the audeo from the clip of interest. Then you can shift and stretch or contract it as nececessary to match the video

    In Cyberlink PowerDirector you right click on the clip in the Media Library and chose Extract Audio. Ckeck the User Manual for your editing program for something similar

    Think of auto as another manual setting. Sometimes it is the most appropriate one to use, for example when conditions are changing rapidly in an unpredictable way. A parade would be an example. Don’t use as a substitute for thinking.

    When I finish a project I produce it as a MPEG4 file and set the frame rate to the full 60fps (not 59.94). This is the format I upload to YouTube. To show it on my flat screen TV I connect my computer to a HDMI port on the TV using the display port on my laptop and a display port to HDMI converter and double click on the file.

    Thank you for your addition. As for 24p and the “cine effect” I think if your TV is 120Hz or higher it will display OK because 24 is a divisor of 120.

    Dear Jennifer, If VM does an article on using a stabilizer I hope it includes video examples of what to expect by an experienced user over some standard course that includes walking back and forth on level ground, panning left and right and up and down and walking up and down stairs. Past reviews that I have seen have not included this.

    I have used CyberlinkPower Director ever since I had so much trouble with Adobe Premier Elements 7 shutting down causing me to have to restore my computer. First 8 Ultra, now I use 9 Ultra. It is 64 bit and I find it to be fast, stable and easy to use. Everything so far has worked like the user manual says it should, (not true with Adobe.) It has no problem with the 1080/60p files from my Panasonic HDC-HS700.

    I have a Panasonic HDC HS700 and shoot in 1080/60P. I edit with Cyberlink PowerDirector 9 Ultra and produce in MPEG4 at 60 fps with no problem. The result plays on my laptop and TV with extraordinary results. Rendering times are very reasonable.

    Rob,

    Some further comments. The product should be in sync with your display. For example my laptop has a screen refresh rate of 60Hz and my TV is 120Hz.

    Incidentally regarding the significance of the recent availability of 60p camcorders and display devices , Douglas Trumbull, a pioneer of fast-frame-rate techniques, describing his earlier experiments said;

    “When we shot test films at 24, 36, 48, 60, 66, and 72 frames per second we didn’t have words in English that described the phenomenon. We immediately saw a profoundly different kind of experience happening up around 60 frames: The surface of the screen became like a window into reality.”

    Mr. Trumbull will receive a lifetime achievement Oscar this month. (Source: San Francisco Chronicle, February 5-11, 2012, Sunday Datebook p. 23)
