Summary | 0001227: Export to Prores broken when image is placed into a container at an odd pixel offset | ||||
Description | Prores (going to YUV422P10); colours completely wrong for RGB24 or YUV420P input. | ||||

Except ffmpeg_encoder_basic_test_mov is fine; YUV420P source. All other tests bad. |
|
Not encoding audio doesn't help so it looks like it's not related to the mux. |
|
Oops. Since when? I recently did a few test with ProRes, both from MP4/MOV sources (Bunny/Sintel) and J2K/DCP, and they worked fine - except for that Space Station Flythrough when downscaling to 2k !?
|
|
Not sure; I'm testing with git head and the colours are totally screwed; a nearly monochrome test image comes out green both on Linux and Mac. mp4 export seems fine. It's a really odd one. I may have to go back and see if I introduced it recently... |
|
On my machine it's broken since at least 2.11.30. |
|
Can I reproduce this with Bunny or Sintel? I have everything back to 2.11.17 or so.
|
|
I just noticed it only happens with 25fps projects... |
|
Now that's funny... Prores strictly SMPTE...
|
|
@carl it's not even that simple. Forcing all export projects to 24fps (both content and project) does not change the result. |
|
Tried it with the Bunny Benchmark - looks exactly like what I reported about the ISS Flythrough - greenish, false color, blocking, etc. I know that I tried a couple of exports in different configurations, and did not experience this, but I also tried dcp->Prores... Quick check: trailer_480p.mov (25) to 25fps Prores - false colours 'to 24/25fps' means 'DCP frame rate' set to 24/25 fps NOW - that ISS flythrough creates the same false color appearance when exported - but it is 29,97. sigh...
|
|
Thanks. I think I've got it now: it was caused by pillarboxing into containers at an odd pixel offset. Should be OK in 2.11.69. Thanks for the testing. |
|
Just tried with 2.11.17 OS X - same result. It may have been there right from the start?! But it only happens from some non-DCP/j2k content to Prores. No problem to create a Prores from a 25fps BunnyDCP. Edit: No wonder since DCPs show no odd pixel offsets...
|
|
Who was that ignorant jerk again who said that export is as simple as grabbing the images that are already in the J2K processing pipeline?
