If you use a TIFF viewer that doesn't recognize the colors are in XYZ, it will display them as RGB and they will look wrong. Anything you have to view DCPs should (hopefully!) recognize the XYZ colors and transform/display them correctly.<br /><br />- chrisChris Perryhttps://www.blogger.com/profile/14573705311410528797noreply@blogger.comtag:blogger.com,1999:blog-12985978.post-305509112382244242011-09-09T07:14:22.124-04:002011-09-09T07:14:22.124-04:00Hi chris,

How do you get the converted DCP onto the right hard drive that we can just plug into the theater system? How long does it take to convert a 1.5 hour HD video?<br /><br />We want to be able to go between our film festival TITLE on the screen then some credits then commercials then to the DCP film, then back to the title and repeat this cycle throughout the film festival.<br /><br />Any help is appreciated since I've been quoted minimum $3,000 to create a DCP feature length.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-12985978.post-49228773862548501582010-11-14T21:12:52.091-05:002010-11-14T21:12:52.091-05:00Cristian -

The thing is that converted the RGB TIFF with the code you've mentioned but the output it looks bad - not only on the computer but also on the screen.<br /><br />It looks like the color depth is very low. I made a color chart(separate gradients for primary colors) and it doesn't look good.<br />What is odd is the fact that the non-converted DCP looks perfect on screen.<br /><br />Any suggestions would be very welcomed.<br /><br />PS: I've tested the DCP on Dolby DSS200Cristian Botehttps://www.blogger.com/profile/04650481578621304167noreply@blogger.comtag:blogger.com,1999:blog-12985978.post-42254797819516685122010-11-01T05:17:33.046-04:002010-11-01T05:17:33.046-04:00It worked!

I think I've successfully made a DCP, I'm testing it tomorrow at a cinema on a Doremi server. <br /><br />I deviated somewhat from your guide to get this all to work in OS X. The only think I couldn't get to work in OS X was mkcpl. Also, opposed to using OpenCinemaTools to make the mxf files I used asdcp-test from http://www.cinecert.com/asdcplib/ as I was having diffculty compiling OpenCinemaTools at all on OS 10.6.<br /><br />My friend Chris also combined steps 2 and 3, deleting the TIF's as they are converted to J2C, which really helps with the storage problem of 1000's of Tif's. We also paralleled this step, and on an 3.8GHz i7 and 7 threads we were getting 1fps on the PNG>J2K conversion (-; The ffmpeg process to PNG can also be sped up if you split the video into multiple files (one for each thread) and then batch rename the PNG's to preserve the sequential naming.<br /><br />I'm trying the DCP tomorrow on a HFS formatted USB stick, as I couldn't find a way to format it to UDF or EXT2 on OS X or Windows 7. Any ideas? I think it will work with the server tomorrow but I would like to have more guaranteed compatibility in the future of course.<br /><br />Thanks again! Its been a tough few days but I think I've cracked it (It play well in EasyDCP Player at least)...but tomorrow will tell!<br /><br />Hope you're well,<br /><br />TobyToby Thttps://www.blogger.com/profile/11829018017168381832noreply@blogger.comtag:blogger.com,1999:blog-12985978.post-67029637108164748572010-10-01T09:10:02.573-04:002010-10-01T09:10:02.573-04:00Chris - I think that the interop vs SMPTE choice h...Chris - I think that the interop vs SMPTE choice happens at the asdcplib level.

But saying that they look good I meant they looked like what I would expect from the X'Y'Z' colour space.<br /><br />When using your code step by step, I get an error as the TIFF to J2C routine starts operating saying "LibTiff: 8 Strip Scheme Compression not implemented". And the J2Cs turn out black.<br /><br />That's why I tried using PPMs instead, it doesn't give any errors, but the image just turns out being junk.<br /><br />Would it be possible for you to send me a couple of your TIFFs (even one would do) so that I see if I get an error on that as well and compare it with mine using TiffInfo? <br /><br />MartinMartin Bonnicihttps://www.blogger.com/profile/10562696395153026487noreply@blogger.comtag:blogger.com,1999:blog-12985978.post-70265244278367214122010-07-12T21:28:45.898-04:002010-07-12T21:28:45.898-04:00Martin - In the method I posted, I used TIFFs only...Martin - In the method I posted, I used TIFFs only in step 2. Is that where you're having difficulties, too? Or are you trying to use TIFFs further upstream in the process? If the latter, what format is your source movie in and what tools are you using for step 1?<br /><br />Don't forget, the code I used to generate the j2c images relies on a very specific format of TIFF image, so if you've skipped any steps I will have a harder time helping you debug the problem. Also, your claim that the TIFFs look good in other packages has me nervous, since if they have the proper RGB->XYZ colorspace conversion, they will look incorrect (color-wise) on a tool that is expecting RGB color.<br /><br />Good luck,<br /><br />- chrisChris Perryhttps://www.blogger.com/profile/14573705311410528797noreply@blogger.comtag:blogger.com,1999:blog-12985978.post-21766042990087483362010-07-12T21:19:38.177-04:002010-07-12T21:19:38.177-04:00Hi Chris,

I'm trying to create a DCP for a project of mine, and whilst following your steps I got into some errors.<br /><br />First, when encoding using TIFFs, I get an error saying that there is a problem with the 8-strip decoding, and the resulting J2Cs are just black.<br /><br />So I switched to using PPMs, but the J2Cs turn out a mess, just a corner of the actual image is visible (although it keeps the resolution) and it's lost all colour data and full of noise. <br /><br />Had you come across these problems? Do you know what could be causing them? <br /><br />Thanks again for posting all this information and I'm appreciate it if you could help me out. <br /><br />MartinMartin Bonnicihttps://www.blogger.com/profile/10562696395153026487noreply@blogger.com
