Serious jag goes with c100 footage
Hi
I’m filming some architecture shots and when I bring my c100 native footage into PP cc 2014 and create a new sequence by dragging footage onto create a new sequence icon to auto conform the sequence settings , I jet very jagged lines in all the lines of the building.
I checked my sequence settings and they say;
Editing mode: AVC-Intra 100 1080i
Time base: 29.97 fps
Pixel Aspect Ratio: square (1.0)
Display Format: 30fps
I’m confused as I am shooting my c100 in the 24pf mode.
Any help is greatly appreciated

Joseph,
Have you found any solution to this? I’m just now reading that the c100 and premiere don’t necessarily output the pristine image it shot. Typically, I have it adjust the settings as they should be automatically, but I have found odd behaviors (lines or jaggedness as you mention I think). When rendered, AVC-Intra 100 1080i (Upper Field First) appears the best…but not with dissolving solids behind titles and such. Not sure about fast action. If I use AVCHD settings, it is not pristine after rendering.
Side note…you’re not talking about moire though are you?

Thomas,
I’m afraid I’ve not found the solution.
I called Adobe and Canon – each claim it is the others problem!
Definitely not talking about moire – this is jagged interlacing artifacts.
Every post I’ve read since says to interpret footage as progressive, but that does not work either.
Anyone else have any ideas?

Well, combining advice between several threads on the web, I’ve found the fix for my noticeable problem. My problem occurred after rendering. The footage would definitely be interlaced when everything about the C100 and my Premiere Pro would suggest progressive. Here is my process.
1. Bring your footage into your working folder.
2. Import them into PP.
3. Select only your MTS files (in case you import any other footage shot on a different camera). Right click and select Modify -> Interpret Footage.
4. Under “Field Order” it probably has “Use Field Order from File: Upper Field First” checked. Select “Conform to: No Fields (Progressive Scan).
5. Drop a clip into the Timeline. If it asks you about changing settings or whatever, just choose yes. The key is to then go to “Sequence” at the top and select “Sequence Settings.” Make sure the editing mode says or change the editing mode to “AVCHD 1080p square pixel.” Now render out some footage.If this doesn’t fix the problem, you’ve actually fixed a problem you didn’t know you had. Trust me. And if you already do this…disregard.
You can fix past videos too. Just open old projects and select all of your MTS files. Do the same steps. Then make sure to change your Sequence Settings as well.
Let me know. I’m curious.

I’m seeing this issue (jaggy lines on renders that is not there prior) with AVCIntra footage.
This is material shot from Sony F5 at 25P and Panasonic P2 footage at 50i and After Effects generated name captions rendered ProRes 4444
With an AVCIntra sequence, rendering to ProResHQ with upper field first, it seems to have problems splitting progressive sources to 2 interlaced fields – resulting in jaggies and what appears to be single field renders. This is particularly pronounced on the name captions. Although weirdly they sometimes render OK.
I’ve left it rendering overnight with Max bit depth and Max quality ticked to see if that will cure the problem.
