Aspect Ratio Explained

• Aspect ratio is the relationship between the width and height of a video or image

• It is written as two numbers, such as 16:9 or 4:3

• Example: 16:9 means 16 units wide for every 9 units high

• This is the standard format for most videos on YouTube and social media

• If the aspect ratio is incorrect, you may see black spaces or parts of the image cut off

How to Check Image Size

• Right-click the image file

• Select Properties

• Click on the Details tab

• Look for dimensions (example: 1920 × 1080)

• Use these dimensions to match your video settings

Setting Custom Aspect Ratio in Shotcut

• Go to Settings

• Click Video Mode

• Select Custom

• Enter your resolution (example: 1920 × 1080)

• Shotcut will automatically apply the correct aspect ratio

Understanding the Black Area

• Black space appears when the image does not match the video frame

• This space represents the set aspect ratio of your video

• It shows that the image and frame are not aligned

Adjusting the Fit

• Adjust the resolution slightly up or down

• Resize the image within the frame if needed

• Aim to reduce or eliminate black space

• Keep the image clear and properly proportioned

Frame Rate Tip

• Keep frame rate at 30 frames per second or lower

• Helps ensure smooth playback

• Creates smaller file sizes

• Improves compatibility across platforms

Key Takeaway

• Proper aspect ratio and frame rate make your videos look clean, professional, and ready to share
