Hi,

We're updating our video editing app to support HDR playback/export and ran into a snag. AVPlayer (with HDR color properties) maintains the integrity of the color of text and other layers (e.g. stickers), however, AVVideoCompositionCoreAnimationTool does not. When the composition is exported, the colors of layers are being converted to HDR as well (deeper colors), which shouldn't be the case. We're using videoCompositionCoreAnimationToolWithPostProcessingAsVideoLayer.

Any help would be much appreciated!

Thanks,

Ed

Sure, I'll file a bug report.

P.S. iMovie and Clips appear to work around this issue. We suspect they're using AVAssetWriter instead of AVExportSession.
