Re: Why does Player report an "invalid frame rate" error for 30fps?
Yes. There haven't been many revisions of that document. 30fps will work on most systems (but not all). The verification in DCP-o-matic player, though, has to complain about this.

Re: Dolby stereo Encoded soundtrack
There is a simple Mid/Side Decoder in DCP-o-matic, which should work nicely with a Dolby SR encoded source. However, it will not decode to surround channels.

Re: Apple Mac Studio performance
Maybe 7fps is normal for 4K-flat on the Mac Studio. Try to perform the 'official' DCP-o-matic Benchmark (2k) on the same machine:

Re: Coding is very slow
Check CPU activity and swap size in activity monitor. Even with modern SSD discs, swapping definitely kills encoding performance. But it could also be the source file, at 900MBit/s and 4k, decoding will certainly take a significant part. You could easily check that out with different source files. S...

Re: Coding is very slow
64 threads is too much for a dual x5680. Pretty sure that this causes the swapping when encoding 4k. Swapping is also the reason why the CPU cores are seen idling.

Re: Coding is very slow
I have seen that happen when DCP-o-matic turns to swapping, which means, number of encoding threads and RAM is not balanced. And often when slower external discs (USB) are used. How many encoding threads have you set? 4k needs four times as much memory as 2k for every thread. Is this a single or dua...

Re: New verifier issues with IOP
Maybe sometimes it would be good to ask these distributors to what spec, standard or verification tool they listen to.

Re: Suddenly weird errors when verifying DCP with Player
I think I have seen it before with much older builds. Probably when using different versions for creation and verification, if I remember correctly. I do admit, it could be just a hint or warning in general, but,from the point of strict validation, it would indeed be an error. Even if it would never...

Re: Suddenly weird errors when verifying DCP with Player
Ooops, I mistook that as the FFEC/FFMC marker requirement for FTR vs. other content types. Still, 'error' or 'warning'?
What is this 'XML malformed' thing? Is it because the XML file does not comply with an XSD, or is it due to some 'low level' character issues, like LF/CR, indentation, etc.?

Re: Suddenly weird errors when verifying DCP with Player
Yeah, the malformed XML thingy pops up occasionally. Maybe Carl can tell us what it actually complains about. From other threads, I thought it was a bug that should have been ironed out already, but don't know about that between test and release versions. As far as I understood so far, you can ignor...
