Hello everyone,  
i have a repeater block with several blocks together including this one.

```
{
  "type": "set",
  "label": "Video",
  "options": {
    "fields": [
      {
        "type": "text",
        "name": "width",
        "label": "Width"
      },
      {
        "type": "text",
        "name": "height",
        "label": "Height"
      },
      {
        "type": "asset",
        "name": "video_mp4",
        "label": "Video format MP4"
      },
      {
        "type": "asset",
        "name": "video_webm",
        "label": "Video format WebM"
      }
    ]
  }
},

```

I would like to limit the type of file I want for the type asset.

Example the type mp4 or type webM.

Thanks

I’m afraid that is not possible, you can only limit the type (by extension) globally and not per field
