Please preserve the original source timecode of 29.97 DF BWF WAV files

Hi ​@Genba3266745503dq7,

Welcome back to the Premiere forums and thank you for reporting this occurrence. We appreciate the information, screenshots, and sample files. As the team investigates this issue, we suggest to override source timecode by going to: Modify / Timecode

Best,

Jonathan

The attached BWF WAV test files were created with the following assigned
source timecodes.

23.976 fps files:

• 2398_1h00m.wav → 01:00:00:00
• 2398_1h10m.wav → 01:10:00:00
• 2398_1h20m.wav → 01:20:00:00
• 2398_1h30m.wav → 01:30:00:00

29.97 fps Non-Drop-Frame files:

• 2997NDF_1h00m.wav → 01:00:00:00
• 2997NDF_1h10m.wav → 01:10:00:00
• 2997NDF_1h20m.wav → 01:20:00:00
• 2997NDF_1h30m.wav → 01:30:00:00

After importing the files into Premiere Pro, Premiere displays the following
Media Start values for both sets:

• 1h00m files → 01;00;03;18
• 1h10m files → 01;10;04;06
• 1h20m files → 01;20;04;24
• 1h30m files → 01;30;05;12

After manually changing the Time Display Format using Modify > Timecode,
the source timecodes are displayed correctly:

• 2398 files: 23.976 fps Timecode
• 2997NDF files: 29.97 fps Non-Drop-Frame Timecode

Requested behavior:

Please display the correct source timecodes immediately when these BWF WAV
files are imported, without requiring the user to manually change the
Time Display Format after import.

The attached ZIP contains the original 1 kHz BWF WAV test files. A screenshot
is also attached showing the incorrect Media Start values immediately after
import.
