✅ Preparing Your Assets

To ensure your Metamedia mints without issue and plays back smoothly, it's important your media assets are optimized. Please carefully read this page for best practices when preparing your media layers.

🔊 Audio

We only support MP3 audio format right now. If you're using multiple audio tracks (or a video with sound), we suggest you normalize all audio files to a maximum peak of -7 dB to prevent distortion and reduce clipping or other harsh, unwanted artifacts. You can do this with a free tool like Ocen Audio. For optimal sound quality, convert your MP3 files from their original lossless format into a constant bitrate of 320 kbps. Many media players can do this, as well as audio editors like Ocen Audio, or many Cloud Conversion tools. We also recommend placing at least short fades in and out of all audio to ensure starting and loop rollovers don't click.

🎬 Video

Currently, only MP4 is supported for video. When you're getting your MP4 ready, pick the resolution and frame rate you want and set a suitable bit rate. YouTube has a good reference for ideal MP4 settings. Again, also with video layers, we recommend placing at least short fades in and out of all audio to ensure starting and loop rollovers don't click.

🖼️ Image

For now, the only supported image format is PNG, with or without transparency. If you plan to use multiple image layers, you may want to make sure they are all set to the same viewing resolution and dimensions as your video layers, eg. 1920 x 1080, 1080 x 1080, 1280 x 720, or 4k HD.

📄 Text

To include a transparent text layer, you need to save your text as a plain text document file (TXT). Most writing apps can do this. This means text formatting is not supported. But in our HTML, you can choose either a serif or sans-serif display font, basic web colors, and a shadow effect for better contrast. We currently don’t support further text styles, but you can always export special text that requires formatting to a PNG image layer.

📁 File Preparation

To prepare your Metamedia for minting, you'll have to tweak some simple HTML text. If you’ve never coded before, don’t worry: it basically amounts to just changing a few words in a text file. To do this, you’ll need a free code editor like Visual Studio Code.

Different minting platforms will have different total file size restrictions, but for smooth participation on the widest number of devices and connections, it’s important to optimize all media files to the smallest possible size without sacrificing quality. To convert and optimize your files, try a service like Online Convert or TinyPNG depending on your content.

💡

Pro Tip: Ideally, try to make sure the total file size of all your assets doesn’t exceed 100 MB; failure to meet this threshold will cause slower loading times and may even prevent your file from being minted on certain platforms.
