6 frames silence while video plays
then 6 frames silence at the end of copyworth pointing out that although these 6 frames front and back are required 'silence' (depending on where they are intending to play it out) you should still be submitting a 30second audio file for a 30second ad
whereas this:
hold frame for 10 secs.
You may require 7 seconds of clock and 3 seconds of black at the front as wellWould not be submitted as part of the audio delivery for ads. In my experience anyway!
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.
