Re: 10 bits file as master

Is there a way you could make a short clip of your original and send it to me for testing? It only needs to be a few frames.

Re: Creating my first DKDM for Distribution

If you make the DKDM right you just need to send them the DCP (like you would send to the theater) and the DKDM. They can use whatever tool they want to create more KDMs.

Re: Encode server on Android device

You'd have to build it yourself, I'm afraid, which (at a guess) would not be especially easy.

Re: Validation Error on Frame size

The DCP data limit is "bits per second" not "bytes per second". All the bitrate calculators I can find calculate that my frame size is 240 Megabits per second. Your math above appears to be use my frame size in bytes to calculate bits per second. Your frame size is 1,310,832 byt...

Re: Validation Error on Frame size

I'm not an expert but when I check every online calculator 1310832 Bytes = 10486656 Bits.
I don't follow what you mean here, I'm afraid!
We have a lot of reports for classic Doremi (Dolphin boards) servers failing well below the official specs.
DoM also issues a warning at 230Mbit/s.

Re: Validation Error on Frame size

DoM is using the SMPTE Bv2.1 recommended values (or should be!) For a frame rate of 24FPS, a 2K distribution shall have a maximum of 1,302,083 bytes per frame (aggregate of all three color components including headers) This corresponds to 1302083 x 8 x 24 = 249999936 bits which seems to make sense a...

Re: Validation Error on Frame size

Hi, are those 1281KB files 1281000 bytes long, or 1311744 bytes long? I.e. on your system is a KB 1000 bytes or 1024?

Re: Add some new keyboard shortcuts for moving around on the timeline

I added a basic shortcut section to the manual for 2.15.x (which will become 2.16.0 just as soon as possible...!)

Re: Speed of exporting to MP4

Passing custom settings to ffmpeg isn't so simple because DCP-o-matic does not call the ffmpeg binary but instead it uses the libavcodec/libavformat C API.
