Another issue is related with custom sequence TC In, in export there is a bug wich mismatch the correct TC IN from sequence.

-3dB sounds like the "power law" issue ... going from stereo to mono, or is it the other way around?  ... hmmm ... don't remember.

I cannot reproduce the start time offset issue, in PPro 24.6.1 (shipping).

 

  1. Create new sequence.
  2. Change start time to 00;58;30;00
  3. Export sequence

    Result: In the export dialog, start time = 00;58;30;00

    Do you see different results in 24.6.1?

Hi Bruce I hope you are well, about the Custom Start TC, I'm using the settings below in the sequence:

 

This is the custom TC IN: 00;58;30;00:

 

 

This is the export changing the tc in to 00:48:44:29:

 

About the Audio with -3dBFS

 

The sequence has 8CH, all Multichannel as you can see below:

The 1kHZ signal is at -20dBFS as you can see in the meter.

 

After the export the same 1kHZ signal is -3dBFS lower as you can see below (this happens for all tracks):

 

 

Sensitive informatation has been blurred. Worth mention that the original content is 23.976fps.

 

Thanks in advanced

Hello Diogo, 

What leads you to believe that -3dBFS is incorrect, for that sequence? 

For the second issue: What steps are you following, to generate the timecode mismatch? How can we see what you're seeing?
