TLDRThis tutorial explains how to adjust the aspect ratio and image size for Midjourney art outputs. It covers different ratios for platforms like Twitter, Instagram, and desktop wallpapers, and provides instructions on how to input specific aspect ratios using the '--AR' option. The video also discusses the ideal image size for various uses, such as headers in Notion and prints, and suggests ways to upscale images for higher quality. It concludes with tips on using custom sizes when standard ratios don't apply.

Takeaways

  • 📐 Use the `--AR` option to specify custom aspect ratios for Midjourney outputs, like `--AR 4x5` for Instagram or `--AR 16x9` for wallpapers.
  • 📱 Be cautious with the `--` option to avoid autocorrect turning it into a single long dash; try different keyboard modes or use `- -` instead.
  • 🖼️ Use Midjourney for creating images suitable for various platforms like Twitter, Instagram, and desktop wallpapers.
  • 🎨 Notion recommends images around 1500 pixels by 600 pixels, which is a 5:2 ratio; use `--AR5x2` in Midjourney prompts.
  • 📈 Instagram and Twitter favor a 4x5 aspect ratio, which is derived from traditional photographic print sizes like 8x10 or 16x20.
  • 🖼️ For high-quality prints, Midjourney's default resolution might not be sufficient; consider upscaling using other software.
  • 🖨️ If you want to print your art, a 4x5 ratio works well, but you may need higher resolution images like 2400x3000 pixels.
  • 📐 For unconventional aspect ratios, like A1-A4 paper (1:√2), use `--W` and `--H` to specify width and height directly, e.g., `--W297 --H420`.
  • 🔍 Midjourney doesn't support ratios like 1:√2 directly, but you can work with specific dimensions to achieve the desired output.

🖼️ Custom Aspect Ratios in Mid-Journey Art

This paragraph discusses how to customize aspect ratios for Mid-Journey outputs beyond the default square shape. It explains the use of the '--AR' option to specify different aspect ratios such as 4x5 for Instagram and Twitter posts, 16x9 for desktop wallpapers, and 9x16 for phone displays. The speaker also addresses the importance of avoiding autocorrect issues with the '--' option and suggests using alternative keyboard modes or manually entering the aspect ratio command. The paragraph further illustrates how to use Mid-Journey for creating images suitable for various applications like page headers in Notion, which recommends a 5:2 ratio, and for printing purposes, where traditional photographic print sizes like 8x10 or 16x20 are commonly used. The speaker also mentions the limitations of Mid-Journey's output resolution for high-quality prints and suggests using other software to upscale the images. Lastly, the paragraph touches on the use of specific dimensions for formats like A1, A2, A3, and A4 paper sizes and provides a tip on how to input these dimensions into Mid-Journey for accurate results.

Keywords

💡Aspect Ratio

Aspect ratio refers to the proportional relationship between the width and height of an image or screen. In the context of the video, aspect ratio is crucial for creating images that fit specific display formats, such as social media posts, wallpapers, or prints. The video mentions different aspect ratios like 4x5 for Instagram and Twitter, and 16x9 for desktop wallpapers, highlighting the importance of selecting the right aspect ratio to ensure images are displayed correctly without distortion.

💡Mid-Journey

Mid-Journey is likely a reference to a specific AI art tool or platform used for generating images. The video discusses how to use this tool to create images with various aspect ratios and sizes, suggesting that it's a versatile tool for artists and designers. The term 'Mid-Journey' might be a brand or a feature within a larger software suite, but the video does not provide explicit details about its broader functionalities beyond the aspect ratio customization.

💡Image Size

Image size pertains to the dimensions of a digital image, typically measured in pixels. The video emphasizes the need to adjust image size according to the intended use, such as for social media where specific dimensions like 4x5 are preferred, or for desktop wallpapers where a 16x9 ratio might be more suitable. The video also touches on the technical aspect of image resolution, suggesting that higher pixel counts are needed for larger prints.

💡Resolution

Resolution in the context of digital images refers to the number of pixels that make up the width and height of the image. High resolution images have more pixels and thus can be printed or displayed at larger sizes without losing clarity. The video mentions that for quality prints, a resolution of 2400 by 3000 pixels is needed, indicating the importance of resolution in achieving professional-looking results.

💡Autocorrect

Autocorrect is a feature in many software applications that automatically corrects spelling and grammatical errors. The video cautions against autocorrect because it can change the '--AR' command into a single long dash, which would alter the intended aspect ratio setting in the AI art tool. This highlights a potential pitfall users might encounter when inputting commands into software.

💡Notion

Notion is a note-taking and organization app that allows users to create and manage various types of content, including text, images, and databases. In the video, the creator uses Mid-Journey images as headers for their Notion pages, emphasizing the utility of AI-generated images for enhancing digital content and the importance of image relevance and辨识度.

💡Instagram

Instagram is a popular social media platform focused on sharing photos and videos. The video mentions Instagram in relation to image aspect ratios, noting that a 4x5 ratio is suitable for posts on this platform. This underscores the need for content creators to consider the specific display requirements of different social media platforms when creating images.

💡Twitter

Similar to Instagram, Twitter is a social media platform where users share content, including images. The video points out that Twitter also accommodates a 4x5 aspect ratio for images, which is a common size for sharing visual content on this platform. This highlights the importance of tailoring image dimensions to the specifications of the platform where they will be displayed.

💡Desktop Wallpaper

A desktop wallpaper is the background image displayed on a computer's desktop. The video suggests that a 16x9 aspect ratio is often used for desktop wallpapers, which is a common widescreen format. This illustrates how aspect ratios can vary depending on the intended use of the image, with different formats being more suitable for different display environments.

💡Upscaling

Upscaling refers to the process of increasing the resolution or size of a digital image or video. The video mentions that while Mid-Journey does not output images with the high resolution needed for quality prints, there are other software tools that can upscale images to meet those requirements. This indicates that post-processing of AI-generated images can be necessary to achieve certain professional standards.

Highlights

Midjourney aspect ratio can be adjusted for non-square outputs.

Use '--AR' followed by the desired aspect ratio, like '--AR 4x5' for a 4:5 aspect ratio.

Be cautious of autocorrect changing '--' to a single dash.

For desktop wallpapers, a 16x9 aspect ratio is recommended.

Phone wallpapers are more likely to be in a 9x16 aspect ratio.

Notion recommends images of around 1500 pixels by 600 pixels for page headers.

Use '--AR52' to generate images with a 5:2 aspect ratio for Notion headers.

Instagram and Twitter posts look good with a 4x5 aspect ratio.

Traditional photographic prints are often in 8x10 or 16x20 ratios.

4x5 is a great ratio for prints, but Midjourney doesn't output high enough resolution for quality prints.

For an 8x10 print, you would need about 2400 by 3000 pixels.

There are ways to upscale images using other software for better print quality.

A Samsung Frame is a good option for displaying Midjourney artwork with a 16x9 ratio.

Shapes without a convenient ratio, like A1-A4 paper, can't use the '--AR' option.

Use '--W' for width and '--H' for height to specify dimensions in millimeters.

Midjourney will convert the specified width and height to an aspect ratio internally.

The output size may vary slightly due to computer calculations.
