@Aaron Carlisle (Blendify) ffmpeg gets the length right because the duration (in frames) has doubled as well as the tbr. If you let Blender change the scene rate to whatever ffmpeg tells it, the length in elapsed time is correct.

I've done some digging, and the loading of multilayer EXR files seems a bit indirect. load_image_single() loads the image with its metadata, then calls IMB_freeImBuf(ibuf); to immediately free the image buffer. A later call to BKE_image_acquire_ibuf() fetches the image buffer from some cache using image_get_cached_ibuf(), which then returns an ImBuf without metadata.

If there were an issue, it would be a regression since 01fa4fb6 but I suspect the duplicated timebase is correct for paff-encoded video, see also tickets #3339 and #5378. In any case, there is most likely a bug in blender as FFmpeg always detects the correct length of the clip, no matter the timebase

It seems that @ronan ducluzeau (zeauro) clarified the issue, and that there is no bug here after all. Closing.

I appreciate your in depth response. I wasn't able to use an Image Sequence by baking paint but was able to use the Weight to bake something for an Animated Weight Group. I never knew that was possible and I'll keep experimenting and learning.

Particles emission does not support animated weight groups, animated textures or image sequence textures.
It is a known limitation of current particle systems.

@ Jens verwiebe; would you mind describing the solution a little bit more in detail?
I'm trying to get DNG support within Blender VSE; but either blender shows a blank frame or crashes.

I can confirm @Sergey Sharybin (sergey) I think this one is for you?
Nov 12 2016
Fixed in the "a" version

I can have a closer look later if you like?
That would be great :)
Don't think it's that strange, every change anywhere in the code that somehow influences context can cause such issues. Typical bContext crap… Couldn't check code yet, but from backtrace it even looks a bit like something that only worked by accident before.

That's so strange. The problem is because CTX_wm_space_image returns null (or rather, CTX_wm_area does it). I can't see what changed in 2.8 to justify that.

I also want to note that color management is messed up in 2.8.

It is the "Open GL render active viewport" result

Ok, tried to reproduce the issue but so far it seems to work fine.
Oct 16 2016
Will have a look tomorrow.
Oct 14 2016
Sorry about that.
What is an exact Blender version you use and what's your OS?
Uuu… actually not OSX-spacific, looks more like some ffmpeg issue then, @Sergey Sharybin (sergey)?
Jul 27 2016
You did it absolutely right. Fix is coming to Git now..

You are simply missing enough particles - starting from 10000 you'll start to get more or less OK results (the area of emission is very small, and afaik particles are first distributed over the whole mesh before textures being taken into account…

Sorry I tought that I uploaded the file but I didn't here it goes.
