How to set frame rate of a shot in maya scene
问题
基本上，我需要从Shotgun中检索镜头的帧速率值，然后将其设置给在Maya中打开的镜头，但我无法看到帧速率值的任何更改：
def query_frame_rate():
"""
镜头级别：如果存在，则返回镜头的帧速率值
层次级别：如果镜头中不存在帧速率值，它会查找相应的项目，
然后从项目中提取帧速率值
"""
sht_entity = db_query.query_context("entity")
result = sg.find_one("Shot", [["id", "is", sht_entity["id"]]], ["sg_frame_rate"])
frame_rate = result["sg_frame_rate"]
if frame_rate == None:
project = sg.find_one("Shot", [["id", "is", sht_entity["id"]]], ["project"])
project_id = project["project"]["id"]
result = sg.find_one("Project", [["id", "is", project_id]], ["sg_frame_rate"])
frame_rate = result["sg_frame_rate"]
return frame_rate
if __name__ == "__main__":
frame_per_second = query_frame_rate()
frame_per_second = 16.0
import maya.cmds as cmds
cmds.playbackOptions(minTime=cmds.playbackOptions(q=True, minTime=True),
maxTime=cmds.playbackOptions(q=True, maxTime=True),
fps=16.0)
#cmds.playbackOptions( fps=frame_per_second )
print("已完成，帧速率已设置为 {}".format(frame_per_second))
所以这是我在这里面遇到的唯一问题，任何帮助都将很有帮助。谢谢！

So basically i have to retrieve the value of frame rate of a shot from shotgun and then set it to the shot opened in Maya but I am not able to see any changes in the frame rate value:
def query_frame_rate():
"""
Shot level : return frame_rate value for shot if it's present
Hierarchy level : If frame_rate is not present in shot it goes for corresponding project
and then extract the frame_rate value from the Project
"""
sht_entity = db_query.query_context("entity")
result = sg.find_one("Shot", [["id", "is", sht_entity["id"]]], ["sg_frame_rate"])
frame_rate = result["sg_frame_rate"]
if frame_rate == None:
project = sg.find_one("Shot", [["id", "is", sht_entity["id"]]], ["project"])
project_id = project["project"]["id"]
result = sg.find_one("Project", [["id", "is", project_id]], ["sg_frame_rate"])
frame_rate = result["sg_frame_rate"]
return frame_rate
if __name__ == "__main__":
frame_per_second = query_frame_rate()
frame_per_second = 16.0
import maya.cmds as cmds
cmds.playbackOptions(minTime=cmds.playbackOptions(q=True, minTime=True),
maxTime=cmds.playbackOptions(q=True, maxTime=True),
fps=16.0)
#cmds.playbackOptions( fps=frame_per_second )
print("Done frame rate has been set to {}".format(frame_per_second))
So yes that's the only issue i am facing here, any help would be great
Thanks

playbackOptions命令可用于查询该值，为了设置该值，您可以使用currentUnit命令https://help.autodesk.com/cloudhelp/2019/ENU/Maya-Tech-Docs/Commands/currentUnit.html
但是，您必须将您的值设置为速率标准字符串名称，如pal、ntsc
例如
// 将当前时间单位更改为ntsc
currentUnit -time ntsc;
这也是github上关于这个主题的一个有用的要点 - https://gist.github.com/gansaibow/c30b93bd80dd9a0396d926c31832c4f7
英文:
playbackOptions command can be used to query the value, in order to set the value you can use currentUnit command https://help.autodesk.com/cloudhelp/2019/ENU/Maya-Tech-Docs/Commands/currentUnit.html
but you have to set your value as a rate standard string name like pal, ntsc
for example
// Change the current time unit to ntsc
currentUnit -time ntsc;
this is also an useful gist on github for the topic - https://gist.github.com/gansaibow/c30b93bd80dd9a0396d926c31832c4f7
