| 12:51 | Sasha_C | Hi everyone. The meeting will be starting in 10 minutes right?
|
| 12:58 | Sasha_C | oops, I see that it's scheduled on 11th November, not the 5th...

|
| 13:29 | Sasha_C | very nice :)
|
| 13:30 | PhilippeJ | ah, was just reading it :-)
|
| 13:45 | se6astian | I am off to the fab lab
|
| 13:45 | se6astian | cnc milling and laser cutting for the enclosure
|
| 13:45 | se6astian | see you

| 20:47 | troy_s | FergusL: If you see se6astian, let him know that the link I gave you in chat (GPU debayer) does exactly what he says - multiple approaches.
|
| 20:47 | troy_s | VNG I believe delivers some of the better results currently.
|
| 20:48 | FergusL | there is still some talk concerning it vs AHD I think, saw this on astrophoto boards
|
| 20:48 | troy_s | And regarding file formats, there are only _two_ required: DPX and EXR. The rest is rubbish.
|
| 20:48 | FergusL | my VNG implem is getting bigger
|
| 20:48 | FergusL | it's almost ridiculous haha
|
| 20:48 | FergusL | but almost done
|
| 20:49 | troy_s | FergusL: Why would you not want to store the Bayered image in EXR? It is perhaps the most ideal for it as the image data is already linear.
|
| 20:49 | troy_s | And a conversion to float is great if done correctly.
|
| 20:49 | FergusL | I thought about that too
|
| 20:50 | FergusL | but then, what are the solutions for debayering ? what software would want to eat that ?
|
| 20:51 | troy_s | FergusL: Custom in-house chains
|
| 20:51 | FergusL | of course
|
| 20:51 | troy_s | FergusL: But EXR makes good sense. Even DPX with a 1.0 TRC gamma flagged is solid as it can store a truly raw data stream as it supports the integer formats as well.
|
| 20:52 | troy_s | (AND buries timecode, AND is universal / canonical, AND etc...)
|
| 20:52 | FergusL | that would certainly ease some of the process, actually : I still have to deal with file addresses, seeking a large file etc...
|
| 20:52 | FergusL | EXR bayered would leave thinghs much more open, and easier, with oiio as an example
|
| 21:00 | FergusL | know somehting about Cinema DNG ?
|
| 21:01 | troy_s | FergusL: The only difference between DPX and EXR is that EXR is much more restrained with format.
|
| 21:01 | FergusL | yes, float only iirc
|
| 21:01 | troy_s | A) Float (half or full) and MUST be linear.
|
| 21:02 | troy_s | DPX is a powerful format, but it is so powerful that it does almost too much, and leaves more room for operator error.
|
| 21:02 | troy_s | But... and this is a big but...
|
| 21:03 | troy_s | DPX is used generally for transfer between houses because it is the only format of the two that allows for a TRC to be specified and burned into the data.
|
| 21:03 | troy_s | So an EXR is generally the entire chain within a post house, but intra-house or house to printer etc, would be DPX. A final "baked" image.
|
| 21:04 | troy_s | (In-house minus say, matte paintings which will be coming from artist-paint tools and likely TIFF)
|
| 21:04 | FergusL | why TIFFs ? that's what the artist tools provide ?
|
| 21:05 | troy_s | FergusL: Because TIFF is the most robust format out of those applications.
|
| 21:05 | FergusL | ok
|
| 21:05 | troy_s | FergusL: If they were more capable of EXR or such, they would likely be used.
|
| 21:06 | FergusL | what about the source -> editorial material step ?
|
| 21:06 | troy_s | (most paint apps are display referred, and as a result don't handle EXR terribly super. Also, Photoshop has a really goofy legacy botchjob with alpha)
|
| 21:06 | FergusL | what would be your ideal proposition ?
|
| 21:06 | troy_s | Never happens
|
| 21:06 | troy_s | Editorial is generated during logging or after a one-light.
|
| 21:07 | troy_s | and once finished, ingested via whatever a pipe uses for grading. Resolve has the various EDL ingestions or even reconstruction from image, Filmlight is EDL methinks, etc.
|
| 21:09 | FergusL | yes I see
