Feel free to DM a copy and we can take a look/compare to their 'findings'.
Generally depending who you're sending it to for TX/who's doing the send you'll need something like:
silence 10 secs
tc starts (10:00:00)
6 frames silence while video plays
then 6 frames silence at the end of copy followed by hold frame for 10 secs.
You may require 7 seconds of clock and 3 seconds of black at the front as well.Have you been given tech specs from a broadcaster? And who is "they" in terms of the people telling you it's out of sync? Send companies like IMD/Honeycomb etc won't do anything to your files unless you pay them usually so I doubt they're adding something. And to be honest they wouldn't care that the audio is out of sync unless it's misaligned with their expected timecode. I.e. a couple of frames of out of sync lips isn't going to matter to them so long as their QC machines don't flag that there's audio outside of the stipulated parameters.

I work in sound post, so maybe not the sort of help you need. can be tricky to get to the bottom of these things... so i’ll just suggest a few possible issues:
Is your finished audio file the same length as the guide audio they gave you? I mean exactly the same!
When you are working on the audio are you laying it back to the first frame of picture? Are they? Are there any frames of black?
(It sounds like you’ve touched on a possible issue with the frames of silence discrepancy).
Or is there a sync pop as reference?
Often confusion with the start point can throw a spanner in the works.
Check the length of the picture you’re working to, to the video they’re laying back to. Make sure you’re both working to the same cut.
It could help if they send you their out of sync layback, so you can compare it to what you’re working to (which is in sync?). As I’ve said.. check the edit, length and the start point of the first frame of picture. Sorry if I’ve missed the point and have not been any help at all! :)

Err ... any professional video editing type people in the house?
I'm having a problem with some audio work I'm doing for some ads. They are telling me all the audio I'm sending them is out of sync, like it's all slightly late, however they are perfectly in sync with the videos they have sent me that I am working to.
They have sent me an earlier video with audio that they are happy with and I've done a comparison to what I'm working with. It seems in their previously completed videos with sound, there is 5 frames of silence at the beginning, however with what I'm working to there needs to be 10 frames of silence with the same audio source to be in sync. Is it possible they are somehow adding 5 frames to their exports that they are giving me that shouldn't be there? They are on Premier btw, and also they are refusing to accept it could be anything their end of course.
