Video Filters used by Movie industry

[mlong30]

I'm planning on purchasing Vegas 6, and upgrade from Ulead. I'm also planning on purchasing Procoder, and Cinema Craft for my encoders.

I'm also considering creating a render server, using my dual processor server, with AVISYNTH or VirtualDub.

Can someone tell me what type of filters if any the movie industry uses, and why, on their videos?


Thanks!

Your question is far too vague to give a sensible answer.

Can someone tell me what type of filters if any the movie industry uses, and why, on their videos?

The answer is, the movie industry uses a lrage range of filters, equipment and techniques depending on what they want to achieve and what material they are working with.

You have to remember that the film industry is working with much higher quality source than you could probably dream of and the equipment in use probably costs more than your house.

If what you want is to achieve the same kind of effects that you have seen somewhere, then say what it is you want to do and someone may be able to help. But expect a long hard road of learning and experimentation ahead of you

2 of the nastiest filters they use are the vertical filter and edge enhancement. Both should be banned. The vertical filter smoothes everything, to make it more compressible. Some studios use it as a matter of course. Other times it's used to make the video more compressible when they try and cram too much onto the DVD. One recent example is the R1 House Of Flying Daggers. Then they try and cover up by using edge enhancement to artificially sharpen it up again. There are a million examples of that, but one particularly vicious example where they ruined a major DVD release with it is the R1 Gangs Of New York.

If you are working with film, then it is physical filters while shooting, chemical treatments while processing, and even optical effects are still used.

If it's digital, or digital effects for film, it will be Inferno (US$250k/seat), Shake (US$5000/seat for Linux), Nuke (Digital Domian in-house that's now public) and in-house written proprietry code. George Lucas does not use avisynth or virtualdub.

but Speilberg is a big AMD fan boy now
and ILM is using free ATHLON RENDER FARMS as a result!

manano - these are after the fact filters used for the DVD versions, not applied to the film release prints. I agree that over sharpening is a major problem with some studios. Fox is a bastard for it. Many of their older releases have been way over-sharpened.

Hi gunsl1nger-

Well, he did say this:

I read that as wanting to know what kind of postprocessing they use, and I assume he's going to put what he creates onto DVD, so I thought it appropriate to warn him what not to do. But you're right; if he plans to show off his production, like in a movie theater, then he wouldn't use those nasty filters. But I get so pissed off when I see how perfectly good movies have been ruined unnecessarily by smoothers and edge enhancement added for DVD that I got a little carried away. Sorry.

1. ILM is lucas

ILM is using free ATHLON RENDER FARMS

hmm , not really

most of what everyone taking about here is not done post -- it's if either the film is scanned or telecined and 100% of the processing , 75% of the time is done by the davinci system right at the source ... and of course the operator of the same ..



shake is used for compositing -- not (ussually) for post dvd work (it would be really rare - but ive done it)

bad film prints would also be cleaned / fixed by using a davinci system or lustre, revival or equal type programs ..

thanks for the correction BJ..promise I know more about VIDEO than FLEM
Didn't Hector Ruiz give those LUCAS DROIDS a lotta free ATHLON GEAR for the endorsements?

I guess I read the question differently and thought it was directed more to post-production work rather than DVD preparation work.

it wasnt really a well phrased question --

btw, ILM does use virtualdub (occasionally) , ive seen it now at several studios and production houses also .. though frame serving hasnt really caught on to much .. most film work though is in 10bit on up - so the average tools need not apply ..
