+# 🚨 Fix "Access Blocked" Error
+
+## The Error You're Seeing:
+```
+Access blocked: video-trim has not completed the Google verification process
+Error 403: access_denied
+```
+
+## ✅ Quick Fix (2 minutes):
+
+### Step 1: Configure OAuth Consent Screen
+1. Go to **Google Cloud Console**: https://console.cloud.google.com/
+2. Select your project
+3. Go to **"APIs & Services"** → **"OAuth consent screen"**
+
+### Step 2: Set Up Testing Mode
+4. **User Type:** Choose **"External"** (if not already selected)
+5. Fill in required fields:
+   - **App name:** Video Trimmer
+   - **User support email:** nipunbatra0@gmail.com
+   - **Developer contact:** nipunbatra0@gmail.com
+6. Click **"SAVE AND CONTINUE"**
+
+### Step 3: Skip Scopes
+7. **Scopes page:** Just click **"SAVE AND CONTINUE"** (don't add anything)
+
+### Step 4: Add Yourself as Test User
+8. **Test users page:** Click **"+ ADD USERS"**
+9. Add: **nipunbatra0@gmail.com**
+10. Click **"SAVE AND CONTINUE"**
+
+### Step 5: Finish
+11. **Summary page:** Click **"BACK TO DASHBOARD"**
+
+---
+
+## 🎯 What This Does:
+
+- **Puts your app in "testing" mode** - bypasses Google verification
+- **Adds you as a test user** - allows you to use the app
+- **Works immediately** - no waiting for Google approval
+
+---
+
+## 🔄 Now Try Again:
+
+1. **Run your video trimmer app**
+2. **Sign in process should work** - no more access blocked error
+3. **You'll see a warning** saying "This app isn't verified" - click **"Advanced"** → **"Go to Video Trimmer (unsafe)"**
+4. **Grant permissions** and you're done!
+
+---
+
+## 🛡️ Security Note:
+
+- The "unsafe" warning is just because Google hasn't verified the app
+- **It's perfectly safe** since you created the app yourself
+- This is normal for personal/development apps
+- All your data stays private and secure
+
+**This fix works for personal use and testing. For public apps, you'd need Google verification, but that's not needed here!**

+- **Video Upload**: Drag & drop MP4/MOV/AVI files or load from Google Drive
+- **Google Drive Integration**: Browse your entire Google Drive to pick videos
 - **Visual Trimming**: Scrub sliders to find exact start/end points
 - **Live Preview**: Video seeks to slider position for precise editing
 - **Audio Playback**: Built-in player for extracted audio
 - **Download**: Get both trimmed video and AAC audio files
+- **Google Drive Upload**: Upload trimmed files back to any folder in your Google Drive
 
 The web interface automatically converts times and calls the command-line script for processing.
 
+### Google Drive Setup (Optional)
+
+To enable Google Drive integration:
+
+1. **Create OAuth credentials**: Follow instructions in `SIMPLE_GOOGLE_SETUP.md`
+2. **Download `oauth_credentials.json`** and place in this directory
+3. **Run the app** - it will open your browser for one-time authentication
+4. **Done!** Browse your entire Google Drive and upload results back
+
+**Note**: Google Drive integration is completely optional - the app works perfectly without it.

+# 🚀 Super Simple Google Drive Setup (3 Steps)
+
+## Overview
+This is the easiest way to integrate Google Drive - just like signing into any Google app!
+
+---
+
+## Step 1: Create OAuth App (5 minutes, one-time)
+
+### 1.1 Go to Google Cloud Console
+- Open: **https://console.cloud.google.com/**
+- Sign in with your Google account
+
+### 1.2 Create/Select Project
+- Click **"Select a project"** → **"NEW PROJECT"**
+- Name: `video-trimmer` → Click **"CREATE"**
+
+### 1.3 Enable Google Drive API
+- Go to **"APIs & Services"** → **"Library"**
+- Search: **"Google Drive API"** → Click it → **"ENABLE"**
+
+### 1.4 Configure OAuth Consent Screen (Important!)
+- Go to **"APIs & Services"** → **"OAuth consent screen"**
+- **User Type:** Choose **"External"** → Click **"CREATE"**
+- **App name:** Video Trimmer
+- **User support email:** Your email (nipunbatra0@gmail.com)
+- **Developer contact information:** Your email
+- Click **"SAVE AND CONTINUE"**
+- **Scopes:** Click **"SAVE AND CONTINUE"** (don't add any)
+- **Test users:** Click **"+ ADD USERS"** → Add **nipunbatra0@gmail.com** → **"SAVE AND CONTINUE"**
+- **Summary:** Click **"BACK TO DASHBOARD"**
+
+### 1.5 Create OAuth Credentials  
+- Go to **"APIs & Services"** → **"Credentials"**
+- Click **"+ CREATE CREDENTIALS"** → **"OAuth 2.0 Client IDs"**
+- **Application type:** Desktop application
+- **Name:** Video Trimmer (or any name)
+- Click **"CREATE"**
+
+### 1.6 Download Credentials
+- Click **"DOWNLOAD JSON"** button
+- **Rename the file to:** `oauth_credentials.json`
+- **Move it to this directory** (where video_trimmer_demo.py is)
+
+---
+
+## Step 2: Run the App
+```bash
+python video_trimmer_demo.py
+```
+
+---
+
+## Step 3: Sign In (first time only)
+- App will **open your browser automatically**
+- **Sign in with your Google account**
+- **Click "Allow"** to grant Drive access
+- **Done!** Browser will close and app is ready
+
+---
+
+## 🎉 How It Works
+
+### **Loading Videos:**
+1. Click **"🔄 Load Videos from Google Drive"**
+2. **Browse ALL your Google Drive videos**
+3. **Select any video** → Click **"📥 Download & Load Video"**
+4. **Video appears automatically** in the player
+
+### **Uploading Results:**
+1. **Check "📤 Upload trimmed files to Google Drive"**
+2. **Optionally choose a folder** (or use root Drive folder)
+3. **Trim your video as normal**
+4. **Files automatically upload** to your Google Drive
+
+---
+
+## ✅ Benefits
+
+- **🔐 Use your own Google account** - no complex setup
+- **📁 Access ALL your files** - entire Google Drive available
+- **📤 Upload anywhere** - choose any folder
+- **🔄 Works like Google apps** - familiar OAuth login
+- **🛡️ Secure** - standard Google authentication
+
+---
+
+## 🔧 Troubleshooting
+
+### "oauth_credentials.json not found"
+- Make sure you downloaded and renamed the file correctly
+- Place it in the same folder as `video_trimmer_demo.py`
+
+### Browser doesn't open for login
+- Copy the URL from terminal and paste in browser manually
+- Make sure you're on the computer where the app is running
+
+### "No videos found"
+- Make sure you have video files in your Google Drive
+- Check file formats: MP4, MOV, AVI, MKV
+
+---
+
+## 🔒 Security
+
+- **Your credentials stay on your computer**
+- **You control what the app can access**
+- **Revoke access anytime** in Google Account settings
+- **No sharing required** - works with private files
+
+**Total setup time: 5 minutes once, then just sign in and go!**

+- ✅ **No complex browsing code** - just paste links
+- ✅ **Works with any file** - private or shared
+- ✅ **Simple setup** - same OAuth as before
+
+### How It Works:
+
+#### 📥 **Loading Videos:**
+1. Click **"Open Google Drive Video Picker"**
+2. **Google Drive opens** in your browser (filtered for videos)
+3. **Select your video** → Right-click → **"Get link"**
+4. **Copy the link** and paste it in the app
+5. **Download & load** - video appears in trimmer
+
+#### 📤 **Uploading Results:**
+1. Click **"Choose Upload Folder"** (optional)
+2. **Google Drive opens** → Navigate to desired folder
+3. **Copy folder link** and paste it
+4. **Trim your video** with upload enabled
+5. **Files automatically upload** to chosen folder
+
+### Benefits:
+- **No custom file browser** - uses Google's proven interface
+- **Works everywhere** - any device with a browser
+- **Familiar UI** - everyone knows how to use Google Drive
+- **Always up-to-date** - uses Google's latest interface
