Question

Thumbnail preview is lagging in bitmovn player. is there any way to improve its performance. When i am hovering the mouse on seek bar its taking few seconds to load updated images. I am using below configuration. We need prompt reply as its production issue. Thanks in advance for helping. The average runtime of my asset is 3 hours.

private Task CreateThumbnailImage(Bitmovin.Api.Sdk.Models.Encoding encoding, Stream stream, Output output, string outputPath)
{

        var sprite = new Sprite()
        {
            AspectMode = ThumbnailAspectMode.STRETCH,
            Name = "Thumbnail images",
            Unit = SpriteUnit.SECONDS,
            Outputs = new List<EncodingOutput>() { BuildEncodingOutput(output, "thumbnail") },
            Width = 100,
            Height = 100,
            ImagesPerFile = 50,
            CreationMode = SpriteCreationMode.INTERVAL_START,
            Distance = 10,
            SpriteName  = "thumb.png",
            Filename = "thubnail.vtt",
            VttName = "thumbnail.vtt",
            Description = "This method will create a vtt file"

        };

        return _bitmovinApi.Encoding.Encodings.Streams.Sprites.CreateAsync(encoding.Id, stream.Id, sprite);

    }

@Kishore @Neil I need a proper solution to the above issues. It has been a week now since I posted about the above issues.

Hi,
Did you try to reduce the amount of ImagesPerFile ?
50 images of 100x100 should create a sprite image of 5000 pixels, which I imagine might be heavy to download and to handle for the browser. Maybe you can check whether reducing it to 10 improves.
