Video artifacts and reduced video size after export

[ilyalatugovskii]

Hi!

After exporting videos using VideoIO, I am experiencing artifacts on the video, even without applying any filters. Additionally, when using the same codecs (in my case, .hevc), the video size is reduced by half. I am looking for suggestions on how to improve the video quality

Thanks and sorry if this is an amateur beginner question.

var configuration = AssetExportSession.Configuration(
      fileType: fileType,
      videoSettings: .hevc(
        videoSize: renderSize
      ),
      audioSettings: .aac(
        channels: 2,
        sampleRate: 44100,
        bitRate: 128 * 1000
      )
    )
    configuration.videoComposition = nil
    configuration.audioMix = audioMix

    self.exportSession = try AssetExportSession(
      asset: asset,
      outputURL: outputURL,
      configuration: configuration
    )

Same problem. How can we increase the quality when importing?

Is this isolated to certain video formats? I'm using h264 and everything works just fine as far as I've noticed.
