Nattress Film Effects Question
Hi Graeme if you’re reading this…
I demo’ed Film Effects 1.5 then just recently purchased 2.1. When I now drag a preset such as Gfilm Basic V2.1 to my clip, the motion blur and studdering is increadbily intense. Even if I set motion blur to “0” the motion of the clip studders too much to use. My first thought is that the video wasn’t shot at 1/60th shutter speed. Is there anyway to check that in post via FCP or AE? Another App? Also, is that the standard shutter speed that a shooter would use or would they have to manually set that on most cameras. This footage is BetaSP by the way.
I’d love to start off with that preset and tweak accordingly but the motion is too much at this point to use and I’m wondering if it’s a lost cause because of the way it was shot? I could go with the look of the presets explorer RT minus the 24 fps conversion but I’d love to have the curve controls.
Any advice is greatly appreciated! Thank you!

My best guess is that it is nothing to do with shutter speed, but that the footage is upper field and the filter defaults to lower field. I think when you change that, things will look better. Failing that, arrange to send me the footage to look at and I’ll sort it out for you.

Hi Graeme,
Thanks for the response. Sorry for the long delay in getting back to you; have been majorly side tracked by a different project.
I’ve tried the 2.1 Basic filter on a variety of footage now and the default settings produce a very blurred look. My footage is defintely lower field first. I capture and playabck in FCP HD via Blackmagic 8-bit easy setup
with no problems. Also the the 1.5 Demo basic filter worked fine on the same footage. I can render out a 12 second clip 720×486 animation codec QT movie which would be about 500MB. What’s the easist way to get that to you? Mail you a CD?Thanks again in advance!!!

Use PhotoJPEG codec 75% or even 50% should be good enough quality to show me what’s going on.

Thanks Graeme, will do. I’ll try to get it to you via yousendit.com on Monday, May 2.

Got the clip. Thanks. Nice shot! I’ll test it out today and see how I get on!

Ok – strange things going on with that footage. You editing in a BMD 8bit timeline? Can’t easily test that without a lot of reconfigureing here, but for that, you’ll have to set the field order of the filter to upper.
When I tried that on a DV timeline it didn’t work, and it didn’t work on lower either – strange. So I saved out your movie from the DV timeline to a DV codec, brought that back in, rendered set to lower (as DV is lower) and it looks beautiful. That’s a really nice crane shot, the movement is super smooth, and with one of the nice film presets it just looks like film. Lovely.

Hi Graeme,
Thank you very much for checking out the file!
I am (capturing) and editing on a FCPHD BMD 8bit timeline, lower field. I just tried the filter as “upper” and no dice.
Are you thinking that it’s a conflict with the Blackmagic codec? There’s really no way that I can use that work around and convert the entire 30 minute movie to NTSC DV to get the filter to work in Lower Field.
Your 1.5 demo filter worked fine with BM 8 bit.
What do you I advise I do?
Thanks again!

AFAIK, the BMD 8bit code is upper field, as it’s a 486 line codec, not a 480 line one. I’ll try and re-arrange my setup today so that I can play that out and see what it’s like here.
The problem is most definately field based, and as to what, exactly is happening, I’m at a loss to know right now, but it’s by far and a way the strangest I’ve had.

Thanks again Graeme!
With all due respect since YOU ARE THE GURU – I’ve learned a TON from reading your Nattress manual for the film filters…I’ve been working in Lower Field 720×486 for the past few years in both Media 100 and FCP. I always render out of AE in Lower Field.
Field order was explained to me in the past as Lower Field for rectangular pixels 720×480 and 720×486 and Upper Filed for square pixels, 640×480. When Media 100 made the switch to 720×486 from 640×480 (around 2001, not sure which version) my workflow HAD to change to lower field.
But again, I REALLY APPRECIATE ALL YOUR HELP and look forward to your next response. I just hope that info may help in some way.
Thanks again!!!

Well, I leaning towards it being a bug in Film Effects and it’s handling of upper field footage. My plan today is to take the code apart and look at it again and see which bit is not liking upper field stuff. This is really strange to me as the code is totally symmetrical when it comes to field ordering, in that it does the opposite for the other field so I can’t quite see where the error is coming in, but I’ll find it….
