I manage DCP delivery and QC for our theater. I've started in DOM Player verifying DCPs delivered by distributors (when they are unencrypted and not from Deluxe) to enhance my QC efforts. I get the occasional errors, SMPTE Bv2.1 errors, and warnings. Most of them I can read and understand if they're a "not best practice but acceptable" such as non-standard frame rate, too many characters in CCAP line, or lack of FFEC/FFMC markers.
Fortunately, I have not come across any yet that are clearly "this DCP is broken and needs to be returned to the distributor" (such as hash mismatches). However, there are some that I have gotten (and others that are listed in Chapter 19 of the manual) that are ambiguous to me - is this an acceptable error, or is a QC-failing error?
My immediate question is, would anybody be kind enough to give me the thumbs up or down in proceeding with the below errors/warnings (not all from the same DCP), and then also would it be possible to create some annotation to Chapter 19 with explanation/implication of errors & warnings? I'd be more than happy to help with that effort, but as I have described, I don't know enough to tackle it solo.
My error list:
Errors:
- A subtitle lasts longer than the reel it is in.
- <MainSoundConfiguration> describes incorrect number of channels (MainSoundConfiguration has 8 channels but sound assets have 16)
- Subtitle asset df155e13-5ee2-41b9-b2fd-0ad0d6dd27e4 has a non-zero <EntryPoint>.
- A 4K JPEG2000 frame has 1 guard bits instead of 2.
- The XML in the closed caption asset [asset]_sub.mxf takes up 624158 bytes which is over the 256KB limit.
- Frame [#] (timecode xx:xx:xx:xx) in asset [CPL]-video.mxf has an instantaneous bit rate that is close to the limit of 250Mbit/s.
- More frames (not listed) have an instantaneous bit rate that is close to the limit of 250Mbit/s.
(I presume this is fine since an error would be thrown if it exceeded 250, but thought I'd double check)
- The CPL [CPL] has no CPL metadata tag.
