We take the require lines and write it into the first 3 lines of the captured pixel and write them back out to VANC on output. Support for this is built in by us and not Premiere as our drivers have to reinterpret the data in the picture lines.
Is there eny way to maintain original timecode when i
convert from uncompressed to MJPG.
I capture from digibeta and get the same timecode as on tape which i
need in my work.
But it seems to mee that afrer chanching compression method i'll
loos timecode data. This is the main reason i started to ask about vanc.
