A presentation and a question...

Hi all!

My name is Andrea and I am from Rome (Italy). I am a new VS X2 Ultimate, so I probably will ask a lot of things about this software...

The first thing I would like to ask you is about audio file I can import into X2 project as a new soundtrack.

Are the 48 KHz 24 bit or 88.2 KHz 24 bit wave formats supported?

Thank you in advance for your help!

Best regards,

andrea riderelli

Hello and Welcome

I'm not sure about the 88.2Khz wav audio file as I have never used a sound file that high but with your other questions the answer is yes!

The best thing to do is try it and report back with the results.

Hi Clevo,

Thank you very much for your reply.

I have tried and it seems to work. The problem I have is with the second audio track (that with 48/24 format) displaying wrong on VSX2 compared to the audio track embedded into video track.

I mean, I have a video file (with audio from camera microphone) with a concert of mine + another hi-fi 48/24 audio track of the same concert.

What I would like to do is to change the original audio track from video with the good one. One of the problems is that I need to syncronize the to audio tracks and then to mute the original one.

The first thing to do is to visually align the two tracks but the screen rendering of the audio tracks, in this case, is absolutely different. (I will try to post a screenshot).

Another problem is that I can't figure out how to get rid of unuseful tracks (Overlay Track, Voice Track) to maximize the visual area of the only two track I need: the Video Track and the new Audio Track.

I know there is the Track Manager, but it seems to be impossible to uncheck those tracks.

Thank you again for your help.

Regards,

andrea

You are on the right track and I know what you mean....you are trying to look at the patterns of the wave graphic to match the patterns.

I've tried doing it that way before and I have always gone back to my aging but trustworthy ears.

If there is a distinct musical passage you could use that to sync both audio tracks. But for me I find that the easiest way is to sinc the very last note...with the idea being that everything before that should be the same.

It's a trial and error thing and it's moments like this one wishes there was a clapper board...if only it were a movie!

Keep nudging and testing till you get it right

Thank you Clevo!

Now I know I am not alone!...

As a matter of fact, I was used to change the soundtrack using Adobe Audition, importing the original video file, changing the audio track, then exporting to a new video file.

All was working very well until something very strange happened. Now, while searching to resolve that issue, I was trying to do the same thing using VS X2.

Ok, I'll give up until I'll resolve the Adobe issue.

Thank you for your help.

Cheers,

andrea

This big challenge you'll have is "aligning" the audio - often referred to as "lip sync"

The smallest unit of time in VS appears to be the duration of a frame - typically either 1/25th or 1/30th of a second. This is seldom fine enough resolution to get good lip sync or to mix one audio track into another (or itself) without a small "blip"

Other users have asked for finer granluarity also.

(oh, and I tend to use Cakewalk for audio/mixing... VS 11.5 did not handle my 96Khz 24 bit audio, I've yet to try it in X2, but I don't have high hopes!)

If 1/25th of a second is not fine enough, what is?

..now there's a question!

I guess that, given that VS is a VIDEO editting app, there would always be some compromise.... I tend to have some form of music rattling through my little films - either as a key part of the composition (on stuff that's just done for fun) or as an underscore on my more public presentations.

Now, say you have a piece running at 80BPM, that needs to be folded on itself. 25 into 80 don't go! But there might also be a piece at 60BPM, and at 73.... and at...

I tend to pull stuff into Cakewalk, mess with it there, and slot it back into VS, but it's a bit of a pain to have to do this.

..OK so having thought abut this and read my last post, it doesn't quite make sense does it

You would have thought that the granularity would be close enough, even if it's not perfect...

Yet if I fold a music track in Cakewalk, I have no issues with timing "blips", and yet in VS I always find I'm just the tiniest bit out...
(Yes, I do magnify the timeline to get the finest granularity I can)

Perhaps I have sensitive ears

If you want to edit audio, it is best done in an audio editor, how good is Cakewalk/Audacity/Soundforge/Audtition's dvd authoring

VS can offer this as well as rudimentary audio editing, but again, if you want full control of authoring, you'd use a dedicated authoring app.

Like a carpenter doesn't just have a 1" chisel in his tool bag, he'll have a range of sizes and several saws, hammers etc
