用Jython/Python创建电影

Question

我正在尝试制作一部电影，同时通过一个循环创建帧。这是节省，但只有第一帧（它作为电影播放-短片！）我试过各种各样的东西，却不知道自己做错了什么。谢谢

def synthesiseFrame(folder):
  folder =r"D:\FOLDER"
  m=0.5
  for x in range(1,121):
    pic=makeEmptyPicture(960,540)
    for x in range (0,960):
      for y in range (0,540):
        r=#some code
        g=#some code
        b=#some code
        color =makeColor (r,g,b)
        px= getPixel (pic, x, y)
        setColor(px, color)
    numStr=str(x)

    m=m+0.0125
    if x<10:
      writePictureTo(pic, folder+"\pic00"+numStr+".png")
    if x >=10 and x<100:
      writePictureTo(pic, folder+"\pic0"+numStr+".png")
    if x>=100:
      writePictureTo(pic,folder+"\pic"+numStr+".png")

  return movie

movie=synthesiseFrame(folder)
folder =r"D:\FOLDER"
file=r"D:\FOLDER\pic00.png"
movie=makeMovieFromInitialFile(file)
writeQuicktime(movie,"D:\FOLDER\movie.mov", 30)
playMovie(movie)

Answer 1

我改变了你的密码。在

• 使用了“%03d”%x而不是if*3。在
• 将“pic00.png”更改为“pic001.png”，因为synthesiseFrame中的循环从1开始。在
• '\'->；os.path.join操作系统（..）；如果没有，请放入import os

def synthesiseFrame(folder):
  m = 0.5
  for frameNumber in range(1,121):
    pic=makeEmptyPicture(960,540)
    for x in range (0,960):
      for y in range (0,540):
        r = #some code
        g = #some code
        b = #some code
        color =makeColor (r,g,b)
        px= getPixel (pic, x, y)
        setColor(px, color)
    m += 0.0125
    writePictureTo(pic, os.path.join(folder, 'pic%03d.png' % frameNumber)) # 3 if -> no if
  return movie

movie = synthesiseFrame(folder)
folder = r"D:\FOLDER"
file = r"D:\FOLDER\pic001.png" # 00 -> 001
movie=makeMovieFromInitialFile(file)
writeQuicktime(movie,"D:\FOLDER\movie.mov", 30)
playMovie(movie)

编辑

• x（在外循环中）->；frameNumber

我在JES video functions和您的代码中的第一眼就告诉我类似（完全有效的示例）：

import os
import random

def synthesizeFrameAndCreateMovie(folder):

  # Create an empty movie to receive the frames
  movie = makeMovie()

  # Compute & save the frames
  w = 40
  h = 25
  nb_frames = 60       # Will give 60 frames at 30 fps => movie duration : 2 sec.
  for z in range(0, nb_frames):
    pic=makeEmptyPicture(w, h)
    for x in range (0, w):
      for y in range (0, h):
        #makeColor() takes red, green, and blue (in that order) between 0 and 255
        r = random.randint(0, 255)
        g = random.randint(0, 255)
        b = random.randint(0, 255)
        color = makeColor(r,g,b)
        px = getPixel(pic, x, y)
        setColor(px, color)

    # Create one frame and inject in the movie object
    filename = os.path.join(folder, 'pic%03d.png' % z)
    writePictureTo(pic, filename)
    addFrameToMovie(filename, movie)

  # return the movie
  return movie

movie = synthesizeFrameAndCreateMovie("D:\\FOLDER")
print movie
#writeQuicktime(movie,"D:\\FOLDER\\movie.mov", 30)
playMovie(movie)
