capture problems 24p, DVCpro50, and the AJSD93 deck

[Jeremy Garchow]

Was the footage shot 24pNormal or advanced? That could be your problem, trying to reverse an advanced pulldown cadence instead of the Normal (3:2) pulldown cadence.

Jeremy,

I believe it was shot “normal.” But Cinema Tools only gives me the “automated batch reverse 2:3:2:3 pulldown” option.

Would that mean that it was shot “advanced”?

thanks,

Luke

…I’ll cut you up good…

[Guidici] “Would that mean that it was shot “advanced”?”

Don’t know what that means. Kona2 has the ability to remove 3:2 pulldown on the fly, but it can be tricky. I would call aja support and have them walk you through it if you’re interested.

When you look at your footage frame by frame are there 2 judder frames or one? That should help you see if it’s advanced pulldown or normal pulldown.

I’m running into the same issue with 24P material shot with the SDX900. Looks like a bug to me. I’m still researching it, I’ll let you know what I find out, please let me know what you find.

I was able to capture via SDI with an iO and I could remove it just fine, but via FW Cinema Tools acts like it’s 24PA material.

yeah, I think it’s either a bug in Cinema Tools or a problem with how our camera’s were set up.

I could NOT get it to work through Cinema Tools. Now I’m using a Kona LH card to digitize it…it does the pulldown removal in real time and also lets me capture the footage at DV resolution.

[Guidici] “it does the pulldown removal in real time”

Did you find that you have normal pulldown or advanced pulldown? How’d you get the Kona to remove it on the fly? Do you always start on an A frame? The reason I ask is that I have wanted to test this method, but I simply have not had the time. Can I learn from you?

Jeremy,

You should be able to remove advanced pulldown via FCP.

With normal pull down, you need to have your inpoint set on an “A” frame. Depending on what your deck offset is set to, you will most likely need to log in at either the “:00” or the “:29” frame.

You’ll just have to test it to see what it is.

Okay. Three follow up questions.

Concerning avdanced pulldown:

Have you tested the advanced pulldown method? I know it’ll work when bringing it in over firewire in the dv50, but what about SDI into uncompressed?

Concerning normal pulldown:

If I log on :29 or :00, will that A Frame be consistent across the whole tape(s), or just that shot?

Someday when I get a couple days, I’ll test this all myself. I’m just curious to what you’ve learned.

I’ve tested it with Firewire…if the video was shot 24pA it works great. Have not tried it through SDI, it would be interesting to know if that works.

Concerning normal pulldown:
If I log on :29 or :00, will that A Frame be consistent across the whole tape(s), or just that shot?

It should be the same for ALL your tapes. It’s related to your deck configuration, not the recording method.

Beautious. If I have a chance to test 24pN over SDI I’ll let you know how it goes.
