Re: Invalid files DPX -> TIF

What is the % doing?
It's a wildcard. because the folder is full of numbered DPX files, that's accounting for that number, which is variable. The convert command, in this shell script, lives within a loop that iterates through all the files in the target folder.

Re: Invalid files DPX -> TIF

Well, like I said - the resulting file is no good, so it's entirely possible that it didn't work and is just ignoring that flag.

Re: Invalid files DPX -> TIF

That code was written by the author of the software we're using, and it works (the percent sign). To be honest, it's been years since I did any real shell scripting, so I'm going with what he did. That said, I did a little more research into the miff format, and I was able to get the script to run w...

Re: Invalid files DPX -> TIF

I've tried running this directly through LibTIFF's tiff2bw tool from a 16 bit TIFF file fresh off the scanner, but I get an error that it only handles 8 bit files. I'm able to get it to work with an 8bit scan, but of course it only outputs 8 bit files, even though I need 16bit files for the target a...

Re: Invalid files DPX -> TIF

Thanks, I'll give the '-depth 16' flag a try when I sit down to work on this after lunch. The drive space really isn't an issue - this is all happening on a machine with 21TB of fast storage. But it's the processing time I'm worried about. As it is, once scanned it will take quite a bit of time to c...

Re: Invalid files DPX -> TIF

Thanks for the suggestions. I'll give the DPX->PNG->TIFF path a try today, though I'm not nuts about having to create another set of images. There will be well over 20,000 of them in the final film, once we're done with the tests, so that's a lot of extra 2k data to generate and a lot more processin...

Re: Invalid files DPX -> TIF

Would you mind posting the TIF file you were able to make? This film is a bit unusual - it's a scan of a home movie made using a short-lived Kodak lenticular color process, so it's not going to look super sharp. There should be lots of vertical lines, and because it's from 16mm it's pretty grainy. I...

Invalid files DPX -> TIF

We need to convert some 2k film scans (DPX, Linear) to TIF, for processing in another command line tool that only accepts TIF. This tool came with a shell script that batch processes all the DPX files in a folder, using ImageMagick, and outputs the grayscale TIF files it wants. However, the resultin...
