Hi, I just bought a new Canon HF R40 camcorder and I am finding a few problems.  I've tried editing in iMovie 09 (iLife09) not sure if that's  and the program doesn't recognize the camera at all.  With the old iMovie program, I would just turn on the video camera and vio recognzied it no problem.  This has left me with transferring movie clips directly from the SD card which seems painfully slow.  Now I was able to put together a short video with iMovie 09 but was unable to use any titles because the program would crash once I pressed the icon for Titles.  BTW I was taping in MP4 formate for the purpose of getting it on youtube. 


So my questions are:

1.  Is editing from digital video vs DV tape slower in general?  At this rate I ask why anyone would find any pleasure in editing with digital video.

2.  Is this because I'm transferring from an SD card vs directly from the camera?

3.  Is iMovie 11 better at handling digital video?

4.  Does anyone know why the program is crashing when using trying to use titles?


I really appreciate any advice with this problem.  I figured it was time to upgrade into a new camcorder but it sure seems that DV Tapes are much easier to work with and I'm on the verge of just returning the camera.

    #1) no; import from SDcard is usually blazing fast, tape is 'real time' only

    but import in iMovie-b is a two step process: shuffling data into Mac, auto-convert into edit-codec = this could be the time-consuming process, but usually is faster-than-realtime either


    #2) no, should be no difference


    #3) iM08 is 5y old; it was - imho! - a public beta, lacking major features for 'serious' editing; not useful; but importing, simple tasks as cut/dissolve shouldn't be no problem; actual iM11 is much 'better', in terms of convenience & features (slow-mo, pic-in-pic, pic-adjustments, green-screen, themes, L-cuts, ...)


    #4) no I remember iM08, as any iMovie version, past or future, rock-solid.

    could have many causes, usually by 'mixed upped' system ....

    you could add the crash report here, maybe it indicates the culprit (such as historic divx-extension etc)


    for DV, SDef, NTSC/PAL, there's no better edit-app than antique iMovieHD6, 'cause it handles the data 'natively'. The new app iM-b (vers08/09/11) does not. It has the endless-discussed drop-field issue (=auto-deinterlacing), which drops quality for SDef/interlaced bottomless. But iMHD6 is of no use for AVCHD …-


    old camera = old software, new camera = new software
