    Can metafuze handle 10-bit 4:4:4 dpx files?

    I've got some Super 16mm film which is waiting to b processed and telecine'd. I have a few questions:

    1. Can metafuze crop the image from 2k to hd or do I have to have find some other app to do this?

    2. Does it matter if the dpx files are 10-bit 4:4:4 or does it have to be 10-bit 4:2:2 or 8-bit? There is no cost difference getting 4:4:4, so I would prefer this along as metafuze can read them.

    Thanks

    MetaFuze can take in DPX of any color depth and create MXF wrapped DNxHD files. You have a choice to letterbox, pillarbox, etc, depending on aspect ratio. You can apply a 1D LUT as needed during the transcode process. See www.avid.com/metafuze

    Re: Can metafuze handle 10-bit 4:4:4 dpx files?

    Thanks for the info.

    So, it doesn't matter if it's 8-bit/10-bit or 4:2:2/4:4:4? But does it ouput in 10-bit as I thought that a future version will work with 10-bit?

    I've tried the software and took in a single 2k frame. With anamorphic it squeezed it horizontally but with letterbox, it put bars top/bottom.

    I was hoping to crop the picture to hd rather then put bars top/bottom. I presume I would have to do that with some external tool.

    Can't you just crop and resize in Media Composer? Also all DNxHD formats that end in "x" are ten bit.

    Currently MetaFuze does not crop, it only scales to a 16:9 frame since its only output is HD. Cropping will eventually lead to the need to target a 16:9 section, which then leads to arbitrary control on a per shot basis. Something we can consider for a future versions. A fast implementation may be a fit width, fit height approach which would crop on either the X or the Y as needed.

    Re: Can metafuze handle 10-bit 4:4:4 dpx files?

    Thanks for that. I wanted to avoid any processing inside Avid (I have Pro not MC). I have found software than can do all sorts of things to the DPX files including cropping.

    I was talking to a lab and they suggested getting the film telecine'd onto HDCAM SR which is 10-bit 4:4:4 but put on a hard drive. Now, I only know this as a tape format. I don't know how you go about reading this from a hard drive into Avid XPress Pro. Can this be done?

    Thanks

    Re: Can metafuze handle 10-bit 4:4:4 dpx files?

    Well if you have enough drives.. you can take your DPX manipulation software to create 16:9 crops from the original into new DPX files that you run through MetaFuze. One question, is the 16mm super 16? That aspect ratio is awfully damn close to 16:9 so all you would have is a slight letterbox anyway.

    If going the tape route - if they have any Avid product in house, they can just capture the tape to hard drive for you in a DNxHD resolution of your choice.

    Re: Can metafuze handle 10-bit 4:4:4 dpx files?

    Thanks Michael. Yes, it is Super 16mm. You're right it's very close to 16:9. I presume (if they don't have Avid), they can convert the HDCAM SR tape output to DPX?

    Thanks

    If they have a Bluefish type card, they can create DPX - but having an Avid hardware capturewill do all that in real time... DPX transcoding is not.

    Re: Can metafuze handle 10-bit 4:4:4 dpx files?

    I talked to the lab that will do the transfer and they said they will re-capture from the HDCAM SR tape into FCP. They were asking what format I want the output to be in. Obviously, it won't be DPX.

    I've no idea what FCP can output, so what would be the next best output from DPX that I could ask them for which would also be compatible with Metafuze/Avid XPress Pro 5.8?

    Thanks

    They don't have an Avid anywhere on that whole lab/facility to capture with?

    You will want them to do the 4:4:4 to 4:2:2 while capturing. They will most likely go to ProRes. Make sure your system has the ProRes codecs installed. Import QT files into Xpress Pro - select the highest DNxHD your app will support.
