    Workflow for Editing JVC Everio HD-7 Video

    Encouraged by a contribution which I read some time ago, I tested import of footage shot with JVC GZ-HD7 in 1920x1080/50i mode. I first tried Square 5's MPEG Streamclip. I batch loaded the *.TOD files into Streamclip, set the export to Quicktime DNxHD-120 with colorspace 709, and transcoded the files. All went smothly. The transcoded file were imported into Media Composer 3.1.1 with import setting color space to 709. In principle it worked fine, however, I found the colors too flat (or washed out).

    I have then recorded a color bars file on the GZ-HD7 (can be set in manual mode under the camcorder's "function-key"). and run the same procedure with this clip as described above. I varied color space coding RGB and 709 for transcode, and similarly for import into MC I tried both settings (RGB and 709). The results witnessed my impression that colors are washed out. Instead of color values RGB 191 for the bars, I got RGB-values of 180 for the bars. I sent a message to Squared 5, but did not receive an answer until now.

    I repeated the color bar test with "TMPG 4.0 Express". The transcode setting was "Quicktime Movie" with DNxHD-120 codec and colorspace 709. The transcoded file was imported into MC with import color space setting of 709. The result was excellent. All color bars had the correct color values.

    From this test My recommendation for a workflow to import JVC GZ-HD7 material is as follows:

    1.    Import *.TOD clips into TMPG

    2.    Format Quicktime DNxHD-120 Colorspace 709

    3.    Transcode clips

    4.    Import of transcoded clips into Media Composer (Import-Setting of color space 601/709)

    Any comments are welcomed.

    As I remember from Liquid, changing the extension to m2t or mpeg made the files import fine.

    I am not sure if this can be done with MC too.

    No, it does not work with full HD. It may work (not tested) if the camcorder is set to 1440CBR and define a HDV-project with MC. But as I work full HD, I need to convert the MPEG-2 files into Quicktime files.

    Joachim,

    Noted your post from last year about importing TODs from your JVC Everio HD-7. I have the same camera, and am a recent convert from Liquid to MC5.  My experience in converting to Quicktime (using either MPEG Streamclip or TMPG 4 Express)  is that it creates files that are 5x or more larger than the original. Wow.  Even with cheap storage that is quite a hit.  Plus, it takes considerably longer converting to QT than to an m2t file.  Any new insights about your experiences? Anyone else?  Am I doing something wrong? It certainly was easier in Liquid, but since it is at its end of life, MC appears to be the future.

    Joachim,

    You are a right clever fellow.  I'm not that smart, but I did think that the export from Sorenson had lightened the contrast of the media.  I thought the export from TMPG4 Express had increased the contrast slightly.  I thought my AVI exports from Liquid were the most accurate (and the most time consuming.)  Nothing technical on my part, just two eyeballs....  I'm not planning on resolving this conversion thing until I have completed my first (This is not a test.) project.

    Peter,

    You are correct about the size of these things...My current project has about 5 1/2 hours of source material and it's consuming approx 650 GB.  But, since I'm new to MC, I'm not deleting anything, so that includes the original TOD files, the intermediate .AVI and .MOV files and then all of MC folder (=330 GB.)  Some phrase like  "ya gotta have big tools to play in the big leagues" would be the sound bite that fits with what I'm seeing.  I can hardly wait until I drop some BlueRay sized files on top of this heap.  I will address the sizes thingie when I finish this project, as well.  Hmmm, maybe a new AVCHD camera....uhhh, the wife might kill me.

    Regards,

    John

    Re: Workflow for Editing JVC Everio HD-7 Video

    Peter,

    I still use the same workflow for the first part, i.e., I convert all .TOD files into Quicktime files (DNxHD 120) with RGB color space using TMPGEnc 4.0 Xpress. With Media Composer 5, I cann now use AMA to have immediate access to the converted Quicktime files. This saves a lot of time and a lot of disk space. If you import the Quicktime files into MC, you can delete the Quicktime files thereafter, and so saving some disk space. With AMA the disk space is determined by the Quicktime files (which you shall not delete).
