Syncing Audio from One Video to Another, Possible?

[maveric]

I had an original video that using some frames from I created an animation. I sequenced all the frames in photoshop and now have a video of the animation with no sound.

It is exactly the same video/length just animated. However, the rendering could not add the audio automatically.

How would I sync the audio from the original video with the new animation? Can it be done?

They are both at 30 FPS.

I have DaVinci resolve 18-free version.

No clue with DaVinci resolve, but you can use clever FFmpeg-GUI, small, portable, no installation, for this:
Because both have the same length and FPS, this is quite simple.
Load your new video without sound, click main, click multiplex, drag and drop the video with sound, the first video and the audio should be checked automatically, set the desired container (mp4/mkv) and click multiplex. Done.

You'll find your new video with sound in the target folder.

ffmpeg -i "original.ext" -i "newvideo.ext" -codec copy -map 1:v -map 0:a output.ext

Replace "ext" with the extension of the A/V files (mp4, mkv, wav, whatever).
