FCP X and AVC intra
Whats the scoop on avc intra? Does it work natively in X or transcode? I’m on location so can’t really test with my system.

Rewraps to .mov just like FCP7.

Ever had the footage look super grainy, or artifacty? Looks like it in the import archive window as well as viewer and external monitor. Looked fantastic during the shoot. But that was SDI out of the camera to monitor. The image looks like a dithered GIF animation if you’re familiar with gif dithering. Kinda posterized/dithered to look as if there’s more colors than there are.
I’ve found a few posts of other people having this issue with intra 100 24p. They normally use the camera to shoot DVCProHD, but as this was a green screen shoot at 24p we opted for 10 bit intra 100.
The footage keys just fine BTW. But the noise and artifacts are actually in the motion. It’s nasty. Think AVR 70.

No, haven’t had that problem.
I have seen issues way before FCPX if Panasonic cameras aren’t black balanced.
I really like AVC-I and it sounds like something went wrong with the setup. What camera was it?

Have you tried bringing footage into Premiere or Avid to see how the native files look out to a monitor?
Maybe you could transcode in another program to Prores if FCPX is having an issue. I used Adobe Media Encoder recently to transcode some AVCHD that was giving me guff in FCPX. It transcoded to Prores quite fast. Not sure if there will be any issues keeping it 10 bit and getting the best key, etc… So YMMV.

Everyone says they love it. But I found a scant number of threads over the last few years that apparently went unresolved. One thread suggested a detail setting. Another suggested a camera issue. This problem is definitely compression related as the green screen is artifact/banding/issue free. Any grain/artifacting is increased with areas of motion. As if the bit rate was just way too low. Perhaps just the wrong green or something makes it lose it’s mind.
See attached for camera model and example. Example is at full quality, 100%, etc. Looks same on FSI monitor or in FCP 7, or converted to ProRes, or in QT X or QT 7 or quickview. It’s definitely recorded to the card this way.

Thanks. I’ve had the same result in 7 and X. Wrapped or ProRes. Even in the load archive or L&T window. It’s there. I’ll give CS6 a try for fun.

I see.
It’s a 1/3″ chip. Avc-I is great, but there’s only so much a 1/3″ 3MOS will do.
My guesses are that drs was on and shouldn’t have been, or gain was set unexpectedly.
In some cameras, Panasonic gives tremendous control of imaging, but you can mess it up if the wrong switch is flipped. Always good to have a base scene file to load in those situations: https://www.panasonic.com/business/provideo/scene-files-new.asp?model=HPX370

Unfortunately none of this could be seen on the 9″ monitor we had in the studio. They were unable to get the camera to shoot 24p DVCProHD, but said they could shoot 24p AVC-I. I looked it up and it being 10 bit and full raster, sounds like a winner, right?
They’re going to check the camera tomorrow, but it’s one of these situations where you basically had less than an hour with someone doing you a favor just to be in the video. Luckily, I guess, the talent isn’t supposed to be on camera very much. But he was so wonderfully animated that we were going to use him more. It still may be ok. It keys fine and in motion it isn’t so bad. Most of it is going back to DVD or company intranet so it’ll be scaled down. But they do play it a bit on HD tvs in the building for a bit.

In 1080 DVCProHD, 24p is only available with pulldown (normal or advanced).
Avc-I is the right call, it just looks like something wasn’t setup quite right. A 17+” monitor should be used. A 9″ monitor is probably extended SD res at best and you should use 1:1 mode if possible.
Black balance, always.
Also, make sure it’s avc-I 100 vs 50.

It is 100. Although panasonic claims that i 50 is still better than DVCProHD, just 420 instead of 422.
Alas we were at the mercy of the setup we walked into. Monitors included. It was a gracious favor. Ya git what ya git.
