How to batch apply vfb color corrections to a sequence?

[PIXELBOX_SRO]

Hello,
getting ready to render a large animation project. Rougly 50 different cameras, everything will be saved to vrimg. We would really love to use the extensive tonemapping/grading features vfb now has but also tu retain freedom of changing it if we find it necessary for some cameras.
So my question of the day is, is it possible to apply the vfb corrrections to already rendered VRIMG sequence???
Struggling to find clues on the forum…
thanks for any help!

Hello,

Unfortunately there is no easy way to do it for now. Currently you could use MAXScript to load images, apply presets and then save results back to file..

As for some future solution - how do you image it would work ? For example would a standalone application work - You provide a folder with many vrimgs, a vfbl preset and some output folder - and that standalone application opens each vrimg in the input folder, applies the preset and then saves it ?

Best regards,
Yavor

I was using the following script to apply lens effects to a sequence, assuming that V-Ray is the current renderer:

fn vfbSequence fileWildCard = (
  local files=getFiles fileWildCard
  for f in files do (
    local filePath=getFilenamePath f
    local fileName=getFilenameFile f
    local fileExt=getFilenameType f

    local outFile=(filePath+"vfb_"+fileName+".exr")
    if not (doesFileExist outFile) then (
      vfbControl #loadimage f
      vfbControl #bloom on -- replace with other commands if needed
      vfbControl #savemultiimage outFile
    )
  )
)

An alternative to Yavor's suggestion for a standalone tool would be a menu item in the VFB itself, f.e. File > Batch process images... but of course it would require you to open 3ds Max (or another V-Ray application). Which one would you prefer?

Hi guys,
thanks for reply!
I imagine both solutions Yavor and Vlado suggested could find their users, both seem valid to pick up the task.
I have absolutely no clue about scripting in MAX. I asume its similar workflow as recording a batch in PS??
Sorry for a stupid question ))

I'm missing the same feature. I would like VFB to work like Adobe Camera Raw, where you can import and edit a sequence of images and also export them. It should also include the denoiser tool.

Vlado, out of curiosity…why was developement of PDPlayed abandoned? Its seems like a perfecr platform for such things..?? If it had similar features as vfb, it could be a great platform for such vatch processing. Or am i mistaken??

Is it possible to add an option to open only VFB2 in vray.exe?
Then we can use VFB2 standalone.

Ideally, double-clicking vray.exe will open VFB2 and File >> Render .vrscene and batch processing etc.
In other words, VFB2 becomes the GUI of VRay Standalone.
