嗨

🔸先到函式庫下載

🔹接著打開範例

🔸點選loop

🔹就會開始撥放影片

🔸接著我們把檔案拉進程式後，用程式碼開啟試試看

import processing.video.*; Movie movie; void setup() { size(640,480); movie =new Movie(this,"launch2.mp4"); movie.loop(); } void draw(){ image(movie,0,0); } void movieEvent(Movie m) { m.read(); }

🔹接著我們用process開啟攝影機試試看

import processing.video.*; Capture cam; void setup() { size(640,480); cam = new Capture(this, 640,480); cam.start(); } void draw() { if(cam.available()) { cam.read(); } image(cam,0,0); }

🔸加了saveFrame();可以存照片在data裡面

import processing.video.*; Capture cam; void setup() { size(640,480); cam = new Capture(this, 640,480); cam.start(); } void draw() { if(cam.available()) { cam.read(); } image(cam,0,0); saveFrame(); }

🔹把圖片轉成影片

🔸選擇資料夾

🔹將data資料夾內的影片丟到第一個程式碼，就可以播放剛剛錄製的影片

import processing.video.*; Movie movie; void setup() { size(640,480); movie =new Movie(this,"video.mov"); movie.loop(); } void draw(){ image(movie,0,0); } void movieEvent(Movie m) { m.read(); }

🔸這樣就可以播放影片了

🔹接著換這個

void setup(){ size(640,480); background(255,0,0); } void draw(){ println(frameCount); } void mousePressed() { loadPixels(); for(int i=0; i<640*480/2; i++){ pixels[i]=color(0,255,0); } updatePixels(); saveFrame(); }

🔸點一下會變這樣

🔹接著讓滑鼠點擊，更多顏色輪流換

color[]c={#BC3F3F,#BC953F,#46BC3F,#3FBCBB,#813FBC}; int now=0; void setup(){ size(640,380); background(#BC3F3F); } void draw(){ } void mousePressed(){ background(c[now]); now=(now+1)%5; }

🔹接著我們先撥放影片，遇到喜歡的地方按下暫停，就可以配上特效的顏色

import processing.video.*; Movie movie; //#EEEEEE #FFEE4A #FFC501 #FE9600 #03001C color [] c={#EEEEEE,#FFEE4A,#FFC501,#FE9600,#03001C}; int now=0; void setup(){ size(640,480); background(#EEEEEE); movie=new Movie(this, "video.mov"); movie.play(); } void draw(){ if(movie.available()){ movie.read(); image(movie,0,0); } } void mousePressed(){ movie.pause(); loadPixels(); for(int i=0;i<640*480;i++){ float bright=brightness(pixels[i]); int now=4-int(bright/67); pixels[i]=c[now]; } updatePixels(); }
