how to embed simple timecode into .exr header

[mr furious]

I know there is the arbitrary data field in the exr options. But i'm trying to figure out how to embed simple frame equivalent timecode into the header so other programs like the Flame could read it properly.

I'm going to try a post process as the procedure has a bit of math to it and inject it into the exr data field. I'm just not sure about format and var name that other programs will see?

thoughts? any ideas?

thanks in advance.

got it.

searching the interwebs... i found this (frames_to_timecode) that i added to a post translate process. seems to work still testing

import math
import maya.cmds as cmds

framerate = 24

def frames_to_timecode(frames):
    return '{0:02d}:{1:02d}:{2:02d}:{3:02d}'.format(frames / (3600*framerate),
                                                    frames / (60*framerate) % 60,
                                                    frames / framerate % 60,
                                                    frames % framerate)

curFrame = cmds.currentTime( query=True )
curFrame = frames_to_timecode(int(curFrame))

cmds.setAttr('vraySettings.imgOpt_exr_attributes', '' ,type="string")
cmds.setAttr('vraySettings.imgOpt_exr_attributes', 'Timecode = %s' % str(curFrame) ,type="string")
