When I’m trying to a conversion with the following parameters:

mediaItem.OutputFormat.VideoProfile = new MainVC1VideoProfile()
                    {
                        Size = new System.Drawing.Size(1920, 1200),
                        Bitrate = new VariableQualityBitrate(75),
                        Complexity = VideoComplexity.Normal,
                        FrameRate = 1,
                        KeyFrameDistance = TimeSpan.FromSeconds(20)
                    };

I’m getting the following error:

The combined width, height and frame rate are too high for this
profile.

Can anyone help me and tell me what are the limitations to each profile?

    VC1’s Main profile can support a maximum resolution of up to 1920 x 1080.
    In your code, you are setting the resolution to 1920 x 1200, hence with a width greater to the maximum allowed.

    Simple profile supports up to CIF resolution (352 x 288) and Advanced profile can decode up to 2048 x 1536 (but with a bite rate = 135 MBits/s).

    It looks to me like your best bet is to resize the source to 1920 x 1080.
