Can a user link Audacity with a video application or player (e.g., Quicktime/Windows Media Player) and synchronise the time between them? Has anyone done this with Audacity?
No.
If you want to edit an audio/video file, that’s usually done with a video editor* which can cut/splice/transition the audio & video together at the same time. Most video editors can also do some audio processing/effects/filtering, etc., so you may not need Audacity.
If you have an audio/video file and you want to do some audio editing/processing that can’t be done with you video editor you can open the audio in Audacity** but you have to be careful not to do any editing that changes the timing (no cutting/splicing, etc.). Then after exporting the edited file you import the new audio file into your video editor. (It’s best to export as WAV because your video editor is probably going to re-compress anyway.)
In any case, you’ll need a video editor if you want to end-up with an audio/video file.
…Some compressed video formats are prone to “lip sync” problems when you split-out and then re-multiplex the audio, so experiment before spending lots of time with this.

- I’ve used Corel VideoStudio and CyberLink PowerDirector (I’m a Windows guy). I’m not super-impressed with either one, but they get the job done, along with several other (mostly-free) audio/video “tools” that I have… There are some [u]free video editors[/u] but I have not tried them.
** For most audio/video formats, you’ll need to install [u]FFmpeg[/u] (if you haven’t done so already). When you open an A/V file in Audacity, you get the audio-only.)
