Hi Mark, many thanks for your helpful tips. I did adjust the settings and the hairline is good now, but the jacket is still shimmering. Please see details in a comment further down this thread (I couldn’t see how to reply to everyone in the thread at once).

Many thanks,
Fiona.

Apologies, Dave, the DV Matte Pro reply was for Jerry above.

Re my original post, I’ve adjusted the settings and I think the hairline is good now. However, much of the dark jacket is shimmering – especially the edge of the jacket on the speaker’s right side (left hand side of the screen as you look at it). It’s most obvious if you watch it fullscreen. I have included a link below for you to watch a clip:
https://vimeo.com/56916144
Password: GreenscreenFCP

The first part is the original footage with no filters apart from colour correction to brighten it up. The second part is the clip with the following filters: colour correction, colour smoother (4-2-2), chroma keyer (edge control: thin/spread 0, softening 15, enhance 0) & and matte choker (edge thin 74, edge feather 51).

The footage was shot on a Sony Z7, 1080i, imported uncompressed. This clip was exported: H.264, 1280 x 720.

Let me know if you need any further information about the settings. I would very much appreciate your advice on how to reduce the shimmering.

Many thanks,
Fiona.

Thanks very much, Jerry. I will consider trying DV Matte Pro if I end up doing more greenscreen, however this is a once-off, so I’ll muddle through on FCP for now.

Many thanks,
Fiona.

Hi Ryan,

Thanks for responding so quickly and thoroughly.

I exported the file as a Quicktime movie (not using QT conversion). I chose Current Settings. It was shot in 1920×1080, audio 48kHz. I didn’t change the codec when exporting. The movie is 18 minutes long. At about 30% of the job, the progress bar stops moving to the right. It’s still shimmering as it it’s working, however the compression never progresses beyond this point.

The movie is not self-contained (it’s a reference file). The reason I tried it this way is because in recent years, whenever I sent a job to Compressor from FCP, it always froze (Problem A). However, I was able to get around the problem by exporting as a QT movie and then importing that file into Compressor. Now that’s stopped working as well (Problem B). I used Compressor Repair to resolve Problem B in the past, but it hasn’t worked this time.

I have read/write permissions to the disk where the QT file exists & where the file is exporting to – it’s the same external drive for both.

I will try with smaller sections as you suggest to see if that makes any difference. I will also test a self contained movie vs a reference file.

What does repairing permissions do?

Thanks a million for all of your help thus far.

Best wishes,
Fiona.
