Hi @Adrian thanks for sharing that.

We were able to successfully generate a thumbnail based on the documentation you provided.

Here is the code snippet in C#

```auto
        // Thumbnail
        var thumbnailOutput = new EncodingOutput
        {
            Acl = new List<AclEntry> { aclEntry },
            OutputId = output.Id,
            OutputPath = outputPath + "/thumbnail"
        };

        var thumbnail = new Thumbnail
        {
            Pattern = "thumbnail-%number%.jpg",
            Unit = ThumbnailUnit.PERCENTS,
            Positions = new List<double?> { 1 },
            Width = 640,
            Outputs = new List<EncodingOutput> { thumbnailOutput }
        };

        thumbnail = await _bitmovinApi.Encoding.Encodings.Streams.Thumbnails.CreateAsync(encoding.Id, inputVideoStream480.Id, thumbnail);

```
