locking audio track to ruler for music video in Vegas pro 15 edit

Hello, I'm hoping someone can help me figure out how to get a full song .wav to be locked to the grid in Vegas Pro 15. I am a musician and would like to use Vegas Pro 15 to make music videos to my songs. I write my music in Abelton Live and export my files as .wav. I am running Windows 10 64 bit. I have tried to enter the track tempo (120 bpm) into the project settings, and have changed the ruler to measures and beats. Unfortunately the song isn't locked to the ruler and the beats drift making it difficult to synch certain parts. I came across one suggestion of "Acidizing the file" so Vegas can lock onto it. Is this correct? and if so any recommendations of software to "Acidize" my tracks.

Thank you.

Does the project sample rate match your audio sample rate (48k or 44.1)?

Hi, thank you.

You were right. My audio was at 44.1 and the Vegas project was set to 48. Changing the sample rate in Vegas seemed to help a lot. Still doesn't lock to the audio but this helps. Thank you.

Not sure what you mean when you say it doesn't lock. Can you expand on that?

Thank you for taking the time and your advice. I am pretty new to Vegas so I have been trying to learn how to do stuff with youtube videos and forum posts. A lot of these are posts when it was under Sony, but it seems Magix has kept the program the same. Looking for solutions I came across some posts in other forums that said if I "Acidized" the track (I guess in Acid pro or Soundforge) that Vegas would then use the "beatmapped" information of the Audio track to set up the grid points to be "locked" to the beats of the song. My issue is that I am trying to get pulses to happen on the drum hits, I can get a few to line up, but still some beats are slightly off making the process tedious. When I zoom in to try and nudge the video over to the drum hit, I am restricted by the grid, which is slightly off.

I guess in theory, if you have your song at a specific BPM and your video timeline is set for a specific BPM, then they should line up. But in video you are also restricted to frames. Your video edits have to be on frame borders so if your BPM does not hit on a frame border, then you have to make a tradeoff. Is this what is happening?

Thank you david-tu. I think you have figured out my problem.

Doing a quick google search for BPM to Frame Rate conversion brings up some resources. And it looks like certain bpms are better for an equal frame rates.

Thanks again for your help.
