When I check the MTS files that my Canon camcorder records in Mediainfo, I can see that in the Audio info it is written in case of every of them: "Delay relative to video: -80ms"
You can see a screenshot here about this: https://postimg.cc/pyf8VT3Y
In case I import these files to Sony Vegas, will Vegas adjust the delay automatically and place the audio and video correctly on the timeline, or after adding the video to the timeline, I should shift the audio manually with 80 ms?
Use a clapperboard and decide for yourself whether it's worth using a brain cell over. Place your video on the Vegas timeline and check if the video and audio lines up enough to suit you. In more than a decade of using Vegas Pro, I have rarely shifted the audio of the source files for any reason. I've used many different cameras and other sources.
Don't waste your fellow forum members time with redirection to commercial picture posting sites. Upload your files to this site.
Though you can buy them cheap, I have my favorite clapperboard.
That file was also an .MTS from a Sony camcorder.
.mts metadata is fully compatible with Vegas, for almost twenty years. Unless you see a sync issue in your final video, it's best to leave track alignment alone. Always try it on a variety of players and reduce the bitrate first if you suspect a problem.
All interframe video is susceptible to sync issues, AVC transport streams by far being the worst.
