Screen Recording
  • If you attach a render texture to the camera, everything the camera sees gets output to that texture. Then you can take a texture from the rendertexture, and change that to a on or jpeg.

    • There's a script for taking screenshots on the Unifycommunity Wiki: TakeScreenshot . The method used to do this is: Application.CaptureScreenshot, [EDIT: Which also has a parameter superSize for high resolution screenshots using an integer multiple of the current screen resolution].
    • It also shouldn't be too hard to post those screenshots to combine this with the example code in the WWWForm-documentation to post those screenshots to a server.
    • There's also an approach to do [-high resolution-] screenshots [EDIT: with any arbitrary resolution]. I have a script which is based on the script posted in Submitting featured content. This will take a screenshot and store it to disk when you press the key "k" (you could change the key by changing the code). You have to attach the script to a camera for it to work:
using UnityEngine;
using System.Collections;
 public class HiResScreenShots : MonoBehaviour {
     public int resWidth = 2550; 
     public int resHeight = 3300;
     private bool takeHiResShot = false;
     public static string ScreenShotName(int width, int height) {
         return string.Format("{0}/screenshots/screen_{1}x{2}_{3}.png", 
                              width, height, 
     public void TakeHiResShot() {
         takeHiResShot = true;
     void LateUpdate() {
         takeHiResShot |= Input.GetKeyDown("k");
         if (takeHiResShot) {
             RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
             camera.targetTexture = rt;
             Texture2D screenShot = new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false);
    = rt;
             screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
             camera.targetTexture = null;
    = null; // JC: added to avoid errors
             byte[] bytes = screenShot.EncodeToPNG();
             string filename = ScreenShotName(resWidth, resHeight);
             System.IO.File.WriteAllBytes(filename, bytes);
             Debug.Log(string.Format("Took screenshot to: {0}", filename));
             takeHiResShot = false;
  • If you need to record video AZScreenrecorder is free and pretty good. You can also do screen recording through ADB, but that requires you to be connected to a computer
    • adb shell screencap /sdcard/screen.png
    • adb shell screenrecord /sdcard/demo.mp4
    • screenrecord has options
  • If you need to add video recording to a Unity App “Images2Video” has a rendertexture recording script.
  • If you’re using C or Java you look into the media codec documentation for really low level stuff, if you’re feeling adventurous.
