clairemp,
I would recommend getting Noah Kadner’s DVD. You can get it at http://www.callboxlive.com. Noah does a great job of clarifying all of this stuff. Its well worth the money.

[clairemp] “Well I think I may have figured this out and would love some confirmation.
I loaded a tape (24p adv) into my deck, opened up the Log & Capture window, started playing the footage and then paused it, restarting it frame-by-frame using the arrow keys.
Four frames are “smooth” and the fifth has that “interlaced look” ~ which, um, I assume to mean that that frame is interlaced. (jagged lines, every other one off-set from the one above and below)When I put in a tape that I know was shot in standard 24p, I see three “smooth” frames and two of those jagged frames, which makes sense given the 2:3:2:3 cadence.
I think I figured it out, yes? I can look at the footage and see what I’ve got before I capture.”
That’s it. One other tip, its easier to tell the interlaced frames from progressive if there is some motion in the frame (i.e. somebody walking past, a car driving by, etc.)

[clairemp] “Is there any way to determine if your footage (miniDV) was shot in standard 24p mode or 24p advanced mode?”
Step through your footage frame by frame. 24p will be 3 progressive frames followed by two interlaced frames. 24pA will be 4 progressive frames followed by 1 interlaced frame.

I searched and destroyed all .lst files then reloaded all my fonts using font book and deleted all duplicates. All is well.
Thanks for the help. -
I think I’ll hold on to one of my M100is and maybe get an HD down the road.

I figured out how to do it with DVCproHD media. The sequence has to be set to the plain DVCproHD not the Blackmagic DVCproHD and the view settings need to be set to the corresponding (size & framerate @ 8bit) Blackmagic HD setting.
[David Roth Weiss] “Since the SD card has only HD input, but no HD output (this is what separates the SD and HD cards), and the down-converted signal is SD, you must think of the output like you would any other SD signal, and monitor it accordingly. Your SD monitor and SD tape deck are expecting just one thing, an NTSC SD signal at 29.97mhz — anything else will not work. So, the view settings should not in fact be set to HD, but rather to SD.”
This makes alot of sense but, (sorry David) it doesn’t work that way. I’m sure you’re right in that it’s not sending an HD signal to my monitor but, the View setting does need to be HD to playback.
Thanks for helping me figure it out.

[David Roth Weiss] “What confuses most people is that Easy setup requires an HD setting, while the view setting needs to be set independently to the proper SD settings and framerate.”
This is what I was doing (unsuccessfully) before I talked to tech support. When I switched the View settings to the corresponding HD settings, it worked.
[David Roth Weiss] “BTW, the BM card will in fact display DVCProHD to an SD monitor as well — I worked on an HD project that way for many months. The setups are not all labled absolutely perfectly, especially the ones that display 23.98 HD as 29.97 SD. But, with enough guesswork and testing you will get it to do exactly what you want. Keep in mind that DVCProHD is an 8-bit signal, so just cycle through every 8-bit SD setup and tinker with framerates until you find the one that works for your HD format and framerate.”
Good to hear. This is what I need.
Thanks for the advice. -
[Joe Paolo] “as I can tell the realtime downconvert feature in decklink only works for 1080i 29.97 to ntsc-sd 29.97”
I tried this combo too and still nothing.

From the Black Magic Design website in reference to their SD cards…
