New subtitle bug

In DOM version 2.9.37, when there's a line with a mixture of words in italics and regular font, the entire line is replicated three times. As far as I can tell, it worked OK in version 2.9.30, so the bug must have crept up somewhere between those versions. For example, this source: -<dcst:Subtitle T...

Re: Most reliable way to copy DCP package to drive?

USB3 or not, I'm still of the opinion that if you can't reliably copy a file from one disc to another without some bits getting corrupted, then you've got some sort of hardware problem. Or possibly, but not very likely, a serious bug in the operating system.

Re: Most reliable way to copy DCP package to drive?

There's nothing special or "magical" about copying the DCP files. Normal copy procedures should work, no matter if you use the command line or some graphical interface. I think it's likely that there's some hardware fault in your computer. Memory error, some problem with the disc controlle...

Re: Dcp with two subtitles ??

Hi kmeh7, Do you want both languages to appear on screen at the same time like Carl suggests? Or do you want the subtitles to be selectable (one language OR the other) at projection time? If so, that would be a case of creating an OV ("Original Version") and two VFs ("Version Files&qu...

Re: Bit-rate for burnt-in subtitles

Well, DOM won't let you create OV DCP with differing bitrates. It will reencode the whole DCP with new bitrate. In the end you'll have two independent DCPs taking very much disk space. My experience is that only frames with subtitles will be re-encoded. Frames without subtitles will just be copied ...

Bit-rate for burnt-in subtitles

Let's say that I have an original DCP that's been encoded at 100 Mbps, and I want to add burnt-in subtitles. Would it be a good idea to set the encoding bit-rate to, say, 150 or 200 Mbps? The logic being that any re-encoding will cause some degrading of image quality, and a higher bit-rate should mi...

Versions of main program vs. encoding servers

Let's say that I upgrade the main station to the latest test version, do I have to upgrade all the encoding servers to the exact same version as well, or can they be different versions? Also, is there a way to read the version of DOM when only the encoding server has been installed, not the main pro...

Re: DCP verification player

I don't know if there's an official name for the subtitle format, but it's usually referred to as "SMPTE 2010". If anyone has a better answer, do tell. As for the full command line, it's exactly the same as the one you used. I only substituted some of the file names for my own. ffmpeg -i j...

Re: DCP verification player

I don't think Carl has much to do with which file formats are supported by ffmpeg. That's something you'll have to ask the ffmpeg developers.

Re: DCP verification player

I've now tested with your subtitle file in combination with a "dummy" DCP that I made out of just a still frame. And it works! I too get the size of the subtitle as "0kB". I guess that's only because the small size of the file is rounded down to 0kB. But the subtitles are still t...
