1. The music you have used in your demo has a strong backbeat and you have chosen to cut on the backbeat. If I wanted to cut on the downbeat instead, would it just be a matter of altering the offset parameter?

The audio analyser detects (almost) every beat. With the parameters "Beat Interval" and "Beat Offset" you can choose which beats  'll result in Markers (in video cuts). With a Beat Interval of 4 and a Beat Offset of 0, the Markers 'll be placed for beat 1, 5, 9, 13 ..... With a Beat Interval of 4 and a Beat Offset of 3 the Markers 'll be placed for beat 4, 8, 12, 16....... Beat Offset "shifts" the sequence, so yes, you can use every (detected) beat. With the parameters "Slide around beats" and "Random Slide" you can shift the Markers "of the beat" on purpose a couple of (video) frames. This can be handy for special effects or a "non robotic perfect" cutting.

2.  How would your tool handle more fluid tempos such as a piece of classical music which is constantly speeding up or slowing down?

The music (audio) analysing and beat detection is done (in the background) by a sophisticated (complex) algorithm of Queen Mary, University of London. My tool uses in the background the command line tool "Sonic Annotator" with the "beatroot-vamp" plugin / algorithm. I expect tempo changes not to be an issue (it is real beatracking and not beat guessing). If there is no real beat in your music I expect that the algorithm 'll not detect all the beats at places you wish; but maybe this means that the music isn't "dictating" where to cut your video. Till now I have not found a better algorithm that "out of the box" produces better beat detecting, with the default values of the (4) parameter settings (which can be changed).

If you want to research and test what is possible with your kind of music, I advice to install Sonic Visualiser with the beatroot-vamp (and other) plugins.

An interesting and useful tool. I hope you publish it.

An interesting and useful tool. I hope you publish it.

I have just published "Music Video Sync V2".
See for more info the link in the first post.

In enclosed in the download a "Quick start guide" that I made.

 

I downloaded it, but cannot unzip it.

I had to split the zip in 2 parts (2 downloads).

"7-zip" (free) and some other zip / unzip programs can unzip the 2 parts.

Got it, thanks!

Hi FocusOnVegas. I would like to download Music Video Sync V2. Where can I do this? What password to use to download. Thank you very much

Doesn't the password he gave in the first post's link work?

Vkmast, I do not have this password. Do you have it or the Music Video Sync V2?

Try using the password given on the linked page. If you cannot find it yourself I think it was "I consider a small donation" without quotes.

@Alexandre

The password is "I consider a small donation" without quotes. On the developer's website he gives this information.

Thank you all for helping me. I'm starting now on Vegas pro.

I have updated Music Video Sync to version 2.1.

Music VideoSync (MVS) can analyse music files (songs) and generates Marker files with “beat positions” of the music files. The Marker files can be imported in Vegas Movie Studio or Vegas Pro. This makes it easy to edit your videos on the beat.

With version 2.1 you can select multiple input music files and process these in one sequence.  MVS ‘ll analyse each music file and ‘ll write one or more Marker files with the beat positions. Great to quickly experiment with multiple songs to discover what works with your video.
You can select a range for the beat interval value and for the beat offset value and generate multiple Marker files at once.

Great app. I cut to music and this is a big time saving.

Question: Is it possible to edit the application as a script? Without Vasst?
