    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

    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
