[BUG] azure media services - crop issue

I believe there is a bug with the encoder in azure media services.

this is my encoding code in C#

                 var aacAudio = new AacAudio(channels: 2, samplingRate: 48000, bitrate: 128000,
                        profile: AacAudioProfile.AacLc);
 
                               rectangle = new Rectangle("656", "0", "1079", "607");

                    var hd3600Kbps = new H264Layer(bitrate: 3600000, height:"640", width:"360");

                    var h264Video = new H264Video(keyFrameInterval: TimeSpan.FromSeconds(2),
                        layers: new[] {hd3600Kbps});
                    var pngLayer = new PngLayer("50%", "50%");
                    var pngImage = new PngImage("25%", step: "25%", range: "80%", layers: new[] {pngLayer});
                    var codecs = new Codec[] {aacAudio, h264Video, pngImage};
                    var mp4Format = new Mp4Format("Video.{Basename}.{Label}.{Bitrate}{Extension}");
                    var pngFormat = new PngFormat("Thumbnail-{Basename}-{Index}{Extension}");
                    var formats = new Format[] {mp4Format, pngFormat};
                    var filters = rectangle == null ? null : new Filters {Crop = rectangle};
                    var standardEncoderPreset = new StandardEncoderPreset(codecs, formats, filters);
                    var outputs = new TransformOutput[]
                        {new(standardEncoderPreset, OnErrorType.StopProcessingJob, Priority.Normal)};


                    await client.Transforms.CreateOrUpdateAsync(_azureMediaOption.ResourceGroup,
                        _azureMediaOption.AccountName,
                        transformName,
                        outputs,
                        cancellationToken: cancellationToken);

I am cropping the video with this info:

{Left: 656, Top: 0, Height: 1079, Width: 607}

The video I have is 1920x1080 using the C# code above, the video needs to get cropped and encoded.

azure media services gives me an output but the output video is not cropped properly.

if I manually change the bit rate of the video on my computer and then encode it again this time it will work. I uploaded both videos as attachments to this issue.

this one is the problematic video, the video that dose not encode based on the code https://user-images.githubusercontent.com/14353301/127079656-667419c0-2de2-45f6-850a-da03041e8e86.mp4

here is the exact same video but with different bit rate and it gets encoded based on the job input
