DCP-o-matic

OK, even with compressed TIFFs which are pretty small (flat-color animation), obviously reading separate files from disk is a bottleneck after all, regardless of file size (I knew that, but this is a bit ridiculous...) ...however, as I just found out, DPX files, be it, 8, 10 or 12 bit, saturate the ...

I tried 16-bit LZW compressed TIFFs. Performance is even less than with uncompressed TIFFs - 7.4 fps (???) with 25% CPU usage ceiling. Basically, the performance doesn't scale beyond 4 threads (it's a 16 thread CPU), no matter how many threads are specified above 4. The Bunny benchmark was 14 fps av...

Thanks...I put 32 threads - no change...I'll try Sintel to compare, and I'll try compressed TIFF to see if smaller files improve the fps (guess CPU usage will be higher due to the need to decompress)...

Hi Guddu - we have a Ryzen 1700 benchmark here - it's impressing for a single CPU machine... https://dcpomatic.com/benchmarks/input.php?id=1 - Carsten Oh, I'm so happy you mentioned Ryzen...I know it's not exactly the topic, but I am underwhelmed - I have Asus ROG with Ryzen 7 1700, total core usag...

From the top of my head I can only say that it's not the encoding problem if the same DCP played fine on 2 other systems...it's some issue with the paricular system, so others here my offer more ideas, especially if you supply the model of the server and projector in question...

I just did a quick test with 2.7.18 and it seems to work now...thank you, sir...

@andy: are you sure there are absolutley no other files in the folder except the JPGs? No thumbnails or such? no mac dot files?...I think that may be what breaks the folder import ...

I will have a tinker now.

...thanks...

Ah, yes...I have already tried this a couple of times before with no success, but gave it another go. However, forcing framerate doesn't seem to work with audio, apparently (as it probably shouldn't since audio has no framerate)...I input 24, click "set" and nothing happens, play length re...

I know there is a work around for the following problem but it is unnecessarily time-consuming so I'm asking the more proficient users here if there is an option that I'm missing... Here goes: I create a 25fps DCP but I also need to make a 24fps INTEROP version...For that I use the possibility to re...
