This footage has some questionable history as it was shot with a JVC HDV camera in 720 30P (I think). The videographer converted it to 16X9 DV (720X480)before he gave it to me. I imported it to Media 100 HDx using the DVCPro 50 codec at 720X486 (I think…this was last week before I experienced the problem, so I wasn’t paying as much attention as I should have been!). I subsequenty “conformed” the clip to 4X3 with the “cropping” option.
I tried both DVCPro 50 and Media 100 HD codecs for the After Effects render, but the “banding” occurred in either case. I guess the “damage” to the file had already been done.
Media 100 playback is “smooth” and does not exhibit obvious field reversal. I also tried the old AE trick of shifting the frame up/down by 1 pixel to reverse the fields and when it’s wrong…it’s very noticeable.
The comments above about the Quicktime “High Quality” could be true. I have not done any more testing as I was able to get around this problem by minimizing the length of the AE rendered clip and haven’t had a chance to look at this a little more “scientifically.” 🙂

March 25, 2007 at 3:07 pm in reply to: There is a problem with Media 100 & After Effects. A real problem! BEWARE!I am seeing the same thing. I am running Media 100 HDX Ver 11.5.1 with the latest OSX and QT. The problem is bands in the final AE rendered files that are very visible when diagonal lines are panned. During the pan, these bands are offset from one another and the edges of these bands are quite obvious. There may be 6 or 8 horizontal bands in the frame.
I have seen the problem with both the DVCPRO 50 and Media100 HD (8-bit) codecs.
My hypothesis is that it may be due to conversions between DV and D1 formats, e.g. 480 vs 486 lines, but my attempts to be consistent between Media 100 and AE have not eliminated the problem.

Yep, it is a problem. I don’t use it unless I am mastering to tape. My decks are all fed from a “house sync” and digitizing doesn’t rely on it. So the only time I worry about it (or use it) is when I “master to tape.”

You can use this deck as a source deck and the RS422 control will work OK

Hi,
I usually Export by Reference from Media 100 HD. Then I either use BitVice or Apple’s Compressor. I prefer BitVice, but I recently had a highly saturated logo that didn’t compress well, and found that Compressor did a good job. BitVice has a “Studio RGB” setting that expands the 16-235 range of Media 100’s codec to 0-255.

Oops, I forgot one important step in using the “Square Marquee” Tool. You need to select “Crop” under the Image Menu.

Another approach is to use square pixels until the end, then change the image size to accomodate your editing requirements. For example:
1. Make sure the pixel ratio is set to “square” under the image menu.
2. Open your photograph in Photoshop CS2. The photograph should be opened with
square pixels.
3. Set the crop tool to 720 px X 540 px at 72 pixels per inch.
4. Drag the cropping tool to create the image you want. Double click to select.
5. Open “Image size” in the Image menu and change the height to either
486 for D1 or 480 for DV. Make sure the “constrain proportions” is unchecked.Another way to crop is to use the “Square Marquee” Tool. You can select “Fixed Aspect Ratio”
in the Options Bar and set 4X3 in the Width and Height boxes.Then follow steps 4 and 5 from above. In this case you will probably need to select both the width
and height in step 5 (unless your photography just happened to be 720 pixels wide). Make
sure the “constrain proportions” is unchecked.HTH

Under the Tools Menu there is:
Snap to other clips with a keyboard shortcut of Uppercase-Command-1.
For removing gaps there are three possibilities under the Program Menu:
Remove All Gaps – Command-K
Remove Gaps to End – Command-J
Remove Gaps in Range – Command-RHTH

I just did a quick experiment and everything seems OK. There were 40 clips in the bin for my test and “Print Bin to PDF” produced three pages for a “Medium Poster” size. The PDF has all the thumbnail images that were in the Bin. HTH
