Horizontal Banding on HD Uncompressed File and DVDS made from it

Hi

I've got a 10 minute project that is an Uncompressed Quicktime, Codec: NONE. It's 25fps 1920x1080. The source material was 35mm.

After getting the file I ran it on FCP on my machine which is a MBPro and I noticed some strange banding going on in the FCP viewer, I assumed it was just the viewer being inaccurate. Weirdly, every file I've made from this QT has had this banding, weather it's a PRORES 422(HQ) or an H.264. I made a DVD through COMPRESSOR/DVDSP and played it on a few household TV'S and the banding is there and extremely strange.

It's very prominent on the DVDS and looks uniform.

Anyone encountered this?

Open one of the source files in Quicktime. Tell us what codec it is.

Sorry I also mistyped 'vertical' when I shouldve said 'horizontal'

the codec is 'none'.

>the codec is 'none'.

That looks like a very weird codec for film scanning. I'll check with the TC house.

Strypes, this is the finished film as a file, I'm not working with the rushes. Basically the film was onlined on a nitris and I was given the finished film in this 'none' codec uncompressed.

Here's another still, from an SD Prores I made from the original Uncompressed HD File, as mentioned before these lines are on any dvds made too



Any help would be greatly appreciated, I have to deliver dvds of the program in a few days and have no idea what to do about the lines.

I am making a guess, but it sure seems like someone didn't bother to watch the piece (i.e., QA/QC) before sending it out (to you). If it's there in the file you received, the Nitris export seems to be faulty. The "none" codec is a weird thing, as well.

I'd check with whomever created the file that you received.

I'm no telecine expert, but that almost looks like analog noise to me. Like what you'd get on a degraded VHS tape, or a bad video cable.

"None" is an eight-bit RGB format, not suitable for use in video workflows. Noise or no noise, you need to send the job back to the online house and have them output a (for instance) 10-bit uncompressed master Quicktime.

To be clear, "None" and "Uncompressed" are two different codecs. "None", as Jeff mentioned, is an 8 bit RGB codec with no data compression, and normally used for graphics. "Uncompressed" comes in 8 bit or 10 bit, depending on which codec you choose, and is 4:2:2 Y'CbCr with no data compression, and is usually used for video purposes.

Thanks for the info guys, is there anything I can do with the file in the meantime to get outputs that don't have these lines or is it useless?

If it's in the source file, you need to check with the guys that sent you the source file.
