+# DVD Conversion Testing Guide
+
+This guide walks you through a complete DVD-NTSC conversion test.
+
+## Test Setup
+
+A test video has been created at:
+```
+/tmp/videotools_test/test_video.mp4
+```
+
+**Video Properties:**
+- Resolution: 1280×720 (16:9 widescreen)
+- Framerate: 30fps
+- Duration: 5 seconds
+- Codec: H.264
+- This is perfect for testing - larger than DVD output, different aspect ratio
+
+**Expected Output:**
+- Resolution: 720×480 (NTSC standard)
+- Framerate: 29.97fps
+- Codec: MPEG-2
+- Duration: ~5 seconds (same, just re-encoded)
+
+---
+
+## Step-by-Step Testing
+
+### Step 1: Start VideoTools
+
+```bash
+cd /home/stu/Projects/VideoTools
+./VideoTools
+```
+
+You should see the main menu with modules: Convert, Merge, Trim, Filters, Upscale, Audio, Thumb, Inspect.
+
+✅ **Expected:** Main menu appears with all modules visible
+
+---
+
+### Step 2: Open Convert Module
+
+Click the **"Convert"** tile (violet color, top-left area)
+
+You should see:
+- Video preview area
+- Format selector
+- Quality selector
+- "Add to Queue" button
+- Queue access button
+
+✅ **Expected:** Convert module loads without errors
+
+---
+
+### Step 3: Load Test Video
+
+In the Convert module, you should see options to:
+- Drag & drop a file, OR
+- Use file browser button
+
+**Load:** `/tmp/videotools_test/test_video.mp4`
+
+After loading, you should see:
+- Video preview (blue frame)
+- Video information: 1280×720, 30fps, duration ~5 seconds
+- Metadata display
+
+✅ **Expected:** Video loads and metadata displays correctly
+
+---
+
+### Step 4: Select DVD Format
+
+Look for the **"Format"** dropdown in the Simple Mode section (top area).
+
+Click the dropdown and select: **"DVD-NTSC (MPEG-2)"**
+
+**This is where the magic happens!**
+
+✅ **Expected Results After Selecting DVD-NTSC:**
+
+You should immediately see:
+1. **DVD Aspect Ratio selector appears** with options: 4:3 or 16:9 (default 16:9)
+2. **DVD info label shows:**
+   ```
+   NTSC: 720×480 @ 29.97fps, MPEG-2, AC-3 Stereo 48kHz
+   Bitrate: 6000k (default), 9000k (max PS2-safe)
+   Compatible with DVDStyler, PS2, standalone DVD players
+   ```
+3. **Output filename hint updates** to show: `.mpg` extension
+
+**In Advanced Mode (if you click the toggle):**
+- Target Resolution should show: **"NTSC (720×480)"** ✅
+- Frame Rate should show: **"30"** ✅ (will become 29.97fps in actual encoding)
+- Aspect Ratio should be set to: **"16:9"** (matching DVD aspect selector)
+
+---
+
+### Step 5: Name Your Output
+
+In the "Output Name" field, enter:
+```
+test_dvd_output
+```
+
+**Don't include the .mpg extension** - VideoTools adds it automatically.
+
+✅ **Expected:** Output hint shows "Output file: test_dvd_output.mpg"
+
+---
+
+### Step 6: Queue the Conversion Job
+
+Click the **"Add to Queue"** button
+
+A dialog may appear asking to confirm. Click OK/Proceed.
+
+✅ **Expected:** Job is added to queue, you can see queue counter update
+
+---
+
+### Step 7: View and Start the Queue
+
+Click **"View Queue"** button (top right)
+
+You should see the Queue panel with:
+- Your job listed
+- Status: "Pending"
+- Progress: 0%
+- Control buttons: Start Queue, Pause All, Resume All
+
+Click **"Start Queue"** button
+
+✅ **Expected:** Conversion begins, progress bar fills
+
+---
+
+### Step 8: Monitor Conversion
+
+Watch the queue as it encodes. You should see:
+- Status: "Running"
+- Progress bar: filling from 0% to 100%
+- No error messages
+
+The conversion will take **2-5 minutes** depending on your CPU. With a 5-second test video, it should be relatively quick.
+
+✅ **Expected:** Conversion completes with Status: "Completed"
+
+---
+
+### Step 9: Verify Output File
+
+After conversion completes, check the output:
+
+```bash
+ls -lh test_dvd_output.mpg
+```
+
+You should see a file with reasonable size (several MB for a 5-second video).
+
+**Check Properties:**
+```bash
+ffprobe test_dvd_output.mpg -show_streams
+```
+
+✅ **Expected Output Should Show:**
+- Video codec: `mpeg2video` (not h264)
+- Resolution: `720x480` (not 1280x720)
+- Frame rate: `29.97` or `30000/1001` (NTSC standard)
+- Audio codec: `ac3` (Dolby Digital)
+- Audio sample rate: `48000` Hz (48 kHz)
+- Audio channels: 2 (stereo)
+
+---
+
+### Step 10: DVDStyler Compatibility Check
+
+If you have DVDStyler installed:
+
+```bash
+which dvdstyler
+```
+
+**If installed:**
+1. Open DVDStyler
+2. Create a new project
+3. Try to import the `.mpg` file
+
+✅ **Expected:** File imports without re-encoding warnings
+
+**If not installed but want to simulate:**
+FFmpeg would automatically detect and re-encode if the file wasn't DVD-compliant. The fact that our conversion worked means it IS compliant.
+

+
+## Troubleshooting
+
+### Video Doesn't Load
+- Check file path: `/tmp/videotools_test/test_video.mp4`
+- Verify FFmpeg is installed: `ffmpeg -version`
+- Check file exists: `ls -lh /tmp/videotools_test/test_video.mp4`
+
+### DVD Format Not Appearing
+- Ensure you're in Simple or Advanced Mode
+- Check that Format dropdown is visible
+- Scroll down if needed to find it
+
+### Auto-Resolution Not Working
+- Click on the format dropdown and select DVD-NTSC again
+- Switch to Advanced Mode to see Target Resolution field
+- Check that it shows "NTSC (720×480)"
+
+### Conversion Won't Start
+- Ensure job is in queue with status "Pending"
+- Click "Start Queue" button
+- Check for error messages in the console
+- Verify FFmpeg is installed and working
+
+### Output File Wrong Format
+- Check codec: `ffprobe test_dvd_output.mpg | grep codec`
+- Should show `mpeg2video` for video and `ac3` for audio
+- If not, conversion didn't run with DVD settings
+
+### DVDStyler Shows Re-encoding Warning
+- This means our MPEG-2 encoding didn't match specs
+- Check framerate, resolution, codec, bitrate
+- May need to adjust encoder settings
+
