Great problem on interlaced footage

Hi all,

I've just started to shoot 1080/50i footage (AVCHD) with a compact camera (Sony HX20V).

My final target is bluray.

I've transcoded with Compressor the original .MTS to Apple ProRes 422 LT.

Edited (in FCP 7.0.3) with some basic cuts and cross dissolve a bunch of test clips transcoded as above.

Produced the bluray with the "share" function.

The result, seen on a 42" plasma TV is awful: a lot of terrible combing and artifacts on any moving object/subject.

My "fixing" strategy will be:

- "sanitize" the system, erasing Perian and the Panasonic AVCHD importer

- verify the Compressor settings for ProRes 422 LT: here i need for your help !!!

- give a try to ClipWrap to transcode .mts->Prores

Any other idea?

Thanks a lot in advance

Ah , sorry. He uses the same FCS version and he make the conversion to ProRes with Compressor (same version i use).

EDIT

I've forgot to say that i've got a try to ClipWrap and i ended with the same identical clip defect.

Ok this is a longshot but, does he have the Panasonic AVCCAM importer?

If he doesn't I would try uninstalling the plug in. It is a Quicktime plug in which enables you to view MTS files in Quicktime player , but I'm not sure if it is reliable for anything else.

Go to your root drive/ library/ Quicktime and remove the Panasonic AVCCAMImporter.component plug in. restart your computer and try log and transfer again.

As I said it's just a thought but it may a conflict in Compressor and log and transfer.

By the way did you log and transfer to Pro Res LT ?

Jun 28, 2012 3:12 AM in response to David Mclaine

Yes he has Panasonic AVCCAM importer installed.

Mee too i had it installed and i've uninstalled it.

I've also uninstalled Perian. Reboot.

Then i did the try with Log & Transfer: problem still there 😟

Also with ClipWrap no better results.

I fear that the end of this story will be a clean re-install of the s.o.+ FCS 😟

Wierd, what does the clip look like before conversion ?

Before you do anything try deleting FCP's preferences here's how:

You will have to re-assign your scratch drive. Make sure you do not lose your scratch files. Transfer them to another location first and them put them back in the right final cut pro folder.

@ hyphen

thanks, i will try it with the procedure you recommend for the scratch files

@ David

If you refer to MTS files they are quite good: not crystal crisp due to the interlacing, but without

the terrible artifacts introduced after the conversion.

Deleting preferences did no results.

Before reinstall EVERYTHING 😠 from scratch i will try to update OS to 10.6.8...

Try one more thing,

Create a new user and start from the beginning, see if that works.

Jun 29, 2012 12:07 PM in response to David Mclaine

David, what do you mean for "start from the beginning" ? reinstalling FCS or starting a new FCP project from that new user?

Jun 29, 2012 12:11 PM in response to leoluca lolli

No, just create a new user and launch FCP and log and transfer your footage into a new project and go through the same process, see if you get different results.

Jul 3, 2012 9:21 AM in response to David Mclaine

No difference, the defect is still there.

Before to erase all and restart from scratch reinstalling OS and FCS i will try to update the OS and i hope and see...

Jul 4, 2012 9:39 AM in response to leoluca lolli

Problem SOLVED !!!! 🙂🙂🙂 just updating the OS to 10.6.8.

Thanks a lot to all for your patience and support.

Have a nice day 🙂

Just to complete the "solution".

Once i've tried to have a Bluray from FCP with the "share" function i've ended up with a Bluray

with the same interlacing problem.

Then i've made another try and i have choosen "send to compressor" and within compressor i've applied a Deinterlacing (even) effect.

After that no more intelacing problem 🙂

Great problem on interlaced footage
