Previously I always use Mainconcept MP4 to render my timeline to internet format, but after I replace my video card, the Mainconcept MP4 rendering is no longer GPU-supported and took very long time (1:4) - So I decide to change to SonyAVC, where I can achieve faster rendering 1:1.5.
However, everytime I upload the video to youtube, always notified below
"The video you uploaded may have audio/video sync issues. Please refer to this article for advice on how to correct this issue should it arise."
Although so far I check, no sync issues arise..., but anyone here ever had this problem?
