Sure custom presets, but what I’m talking about is bitrate.

And I can’t get those bitrates even with the settings maxed out…

[Andrei Popa]

Hey Walter,

Noise seems to work…

Thanks!

I love these things (technical quirks that you would never think about and are the exact opposite of what you’d expect)

[Andrei Popa]

It seems I haven’t read Charlie’s post correctly, he said I should add a blur and I understood I should remove it…

I tried it, and it doesn’t seem to do much, but it is a good idea…

Where can I find the one pass CBR setting in Compressor? I know it exists inside Adobe Media Encoder, but can’t find it in Compressor for .mov containers…

“the projection of your project would be slightly less sharp than your computer screen”

I guess a higher bitrate will make it sharper on the big screen…

[Andrei Popa]

Hi guys,

Thanks for the replies.

Robin

I think you did not read properly my initial post nor my reply. I said that the master file shows the artefacts.

Bret

If you look at it carefully there are artefacts, Charlie described it best as “kind of moving graininess” it’s more like lines / waves or waves of lines as opposed to the traditional square artefact.

These artefacts appear in the center about midway between the writing and the bottom of the screen.

It’s not so bad, but it shouldn’t be there, and if projected on a big screen it may look worse…

Charlie

That background is a generator that comes with Final Cut X. It does not have any blur function/control on it.

I find it very odd, because there shouldn’t be any problem at all, especially since it’s a built in generator, it’s not third party plug-in or a video file.

So my only explanation is FCPX is messing up…

Of course I’d prefer to fix it but I’m not sure it’s possible…

P.S. I watched it carefully inside FCPX after I wrote the above, and the artefacts are there as well, I don’t have any other effects plugins on this generator, so I guess it’s a FCPX mess-up…

Last but not least:

1. Is there any way to specify a fixed bitrate in FCPX or Compressor (fixed bitrate, not maximum bitrate limit)

2. This clip is about 7mbps at 720P

Is 12mbps at 720P make any difference on a big screen?

Theoretically it should, but if it’s crisp at 7mbps on your computer screen isn’t it going to be the same in the cinema?

The cinema screen will be way bigger, but the projector will still be putting out 720P…

[Andrei Popa]

The youtube is just an example, so people can see the artefacts.

The error is in the original file I rendered on my computer as well, it comes out like that when FCPX renders it.

[Andrei Popa]

Definitely.

This was just a test, so I can see how it works, and how should I shoot it.

🙂

[Andrei Popa]

Yes, rotoscoping in kind of hardcore.

Probably shooting them separately with greenscreens, (or at least the girl, because I already have the person in the suit keyed), is the best option.

I heard there is this plug-in called Slice X, that is kind of like an auto-rotoscope, but I’m not sure how well it would track moving people.

[Andrei Popa]

True, only that I was saying:

By shooting them separately I meant to rotosocope.

If I shoot them together and key the person in the suit it works fine.

Nevertheless, your option of greenscreening both is even better.

[Andrei Popa]

“It helps to figure out what (and how) you want to do something before you start shooting.”

That’s exactly what I’m doing now, this is a test.

I wanted to see if there are any benefits of shooting the characters separately.

It works pretty well together (both characters shot at the same time).

Looks like shooting them separately in this case is an unnecessary pain.

[Andrei Popa]

Yup, both methods work, Andy’s and Dave’s, I was using the normal invert, and I think Dave was talking about Alpha Invert.

I also realized why I can’t get them on top of another the way I want.

The keyed person is alpha, but the girl is with the background.

So I would actually need 3 layers, background, girl alpha, keyed person alpha.

I’m only new to compositing so…
