4.1.8.0 HDR Upconverter Output Ruined

Damundai

Using the new HDR Upconverter AI in 4.1.8.0 outputs extremely low bitrate video (with SDR input) and changes all audio to AAC (not keeping original, even though that is what was selected). Also removed all subtitle tracks. Kept chapters intact. Had to revert back to 4.1.7.0 for now until the problem is fixed.

Hello,

Thank you for providing detailed feedback regarding the output issues with HDR Upconverter AI in UniFab 4.1.8.0.

According to your description, when using an SDR video as the input, the output video has an unusually low bitrate, the original audio tracks are converted to AAC despite the option to keep the original audio being selected, and all subtitle tracks are removed. However, the chapter information remains intact. We also understand that you have temporarily reverted to version 4.1.7.0.

To help our technical team investigate the issue further, please provide the relevant task logs, screenshots of your output settings, and, if possible, a short source file or sample file that can be used to reproduce the issue. If you are unable to share the source file, please let us know its video, audio, and subtitle formats, as well as the output settings you used.

Once we receive this information, we will submit the issue to our technical team for further analysis. Until the issue has been confirmed and addressed, we recommend continuing to use version 4.1.7.0, which is currently working properly for your tasks.

We sincerely apologize for the inconvenience and appreciate your understanding and cooperation.
