Hello,

you can use RenderDocument() to render single frames or a whole frame sequence of a given document. You can save the images or videos in the formats supported by your system. See this list of available formats.

  
  # get render data  
  doc = documents.GetActiveDocument()  
  rd = doc.GetActiveRenderData().GetData()  
    
  # prepare bitmap  
  xres = int(rd[c4d.RDATA_XRES])  
  yres = int(rd[c4d.RDATA_YRES])  
    
  bmp = bitmaps.BaseBitmap()  
  bmp.Init(x=xres, y=yres, depth=24)  
    
  # set render data  
  rd[c4d.RDATA_MULTIPASS_ENABLE] = False  
  rd[c4d.RDATA_PROJECTFILE] = False  
    
  # sava as...  
  rd[c4d.RDATA_GLOBALSAVE] = True  
  rd[c4d.RDATA_SAVEIMAGE] = True  
  rd[c4d.RDATA_FORMAT] = c4d.FILTER_MOVIE # save as Quicktime movie  
    
  # preview range  
  rd[c4d.RDATA_FRAMESEQUENCE] = c4d.RDATA_FRAMESEQUENCE_MANUAL  
  rd[c4d.RDATA_FRAMEFROM] = c4d.BaseTime(0)  
  rd[c4d.RDATA_FRAMETO] = c4d.BaseTime(1)  
    
  # get target path  
  path = c4d.storage.SaveDialog(title="Save preview")  
  rd.SetFilename(c4d.RDATA_PATH,path)  
    
  # render  
  res = documents.RenderDocument(doc, rd, bmp, c4d.RENDERFLAGS_EXTERNAL | c4d.RENDERFLAGS_NODOCUMENTCLONE)

Hi Sebastian,

I was trying the above code but the result is always a 0 byte file. I am looking into it.

Thanks

Hello,

be aware that you must have Quicktime installed on your system to save Quicktime movies.

Hi,

I am able to generate preview in .avi format using above code but the size of the file being generated after rendering process is very large.
We can compromise the quality of the preview. Is there any way to decrease the time of rendering and more importantly the size of the final preview.

Thanks

Nishant

Hello,

the size of the file depends on the used codec and other file settings. In case of AVI you must set the
corresponding AVI parameters. You find some example how to get these parameters in this thread.

The video settings must be saved in the RenderData's RDATA_SAVEOPTIONS subcontainer.

Best wishes,
Sebastian
