There is no Vegas Pro Platinum. Are you using Vegas Movie Studio Platinum 14? If so a moderator can move this post to that forum, or you can delete this one and repost there. This isn't a problem that I have heard of in either Vegas Pro or Vegas Movie Studio.

Yes you're right, it's Movie Studio Platinum. Hopefully a mod can move it, I'll post the screen for Cornico so maybe they can look at it and tell me what's up.

I'm curious at the screenshot and special the part of the audio track where your stretch has been started.

Not sure what you mean about the special part where the stretch started, the entire track was squished a little and therefore sped up slightly to match the length of the video.

Convert the MP3 to a WAV file first then bring on timeline as WAV file and see if that helps. Some MP3s do not get treated right.

Thanks for the screenshot.
I thought maybe you "forgot" 😉 pushing CTRL and that should be visible.
I see nothing strange, sorry but here stops my help.
Maybe to save the project with another name, re-open again and render again?

Thanks for the suggestions. I converted it to a WAV through Audacity. Then in Movie Studio I trim off the end with basically no sound by dragging without hitting control, then I drag with control to sync it up to the video length. Once again it matches up right in the "editor" but when I render it, the music ends about 9 seconds too early. I would give another screenshot but it looks the same to me. Maybe the audio time stretch method needs to be changed?

Here is the video in question:

Something strange somewhere. Try exporting the audio tracks only to a wav file to see what length this has. If it is correct use it on the timeline instead of your original audio tracks.

Something else strange. On the timeline your video is 4954.60 frames long? At 60 fps this is 1min 22.58 secs yet YouTube says its length is 1.43. I did enjoy the video.

Couple of weird things, I'll give the screenshot... So my video says it's 6182 frames in the preview panel, but in the bottom panel it shows under 5000 frames. When I export the video, muting the video audio, as a WAV file, and reinsert it into the audio layer, it comes out as the video length of 1:43, but as you can see in the audio layer, it ends too soon.

Yes very strange. Perhaps you've stumbled across an obscure bug.

You could try trimming off the end silence of the wav file and stretching it out to the required length. Then exporting it with the video again.

I tried that, and I emailed tech support and they told me to just import and trim without stretching. None of this is working :( There must be something I'm missing? I feel like this shouldn't be so complicated.

This sounds very much like a sample rate mismatch. What sample rate is your original audio recorded at? Most recording equipment will default at 44.1Khz while most video is rendered at 48KHz. Not sure if MS resamples or not.

Hmm so the audio render settings as well as the project settings were at 48KHz. The original audio is 44.1KHz like you said. I changed the video and render settings for the audio to be 44.1KHz and there's still the mismatch. Unless there's another setting I'm missing? Why is this so difficult for me?? lol

Just to be sure: you want to set the project ("Project/Properties") so that the audio sample rate is 44.1Khz. Then you render it - with a template modified to output audio at 44.1. If that works, then you try and render with a standard template (which outputs at 48Khz) to see if MS can resample properly (it should).

Of course it's a long shot and it may well be that it's nothing to do with that :( Still - at least in audio, I'm less knowledgeable with video - uncorrected sample rate mismatches tend to cause that kind of drift so it's suspicious..

Another option is to do the audio stretching in an audio-dedicated program, for example you can download Reaper. MS being focused on video, its audio-related functionalities may simply not up to it.. audio stretching is an awesome functionality and pretty complex.

If you stretch your audio in a DAW to the right length and then bounce it as a WAV file, it will solve your problem very quickly.

Thanks for the reply Cris. So I tried it with Audacity and it still didn't match up. So I tried leaving the audio overhanging in MS and although it appears the audio is too long, the music ends at the right time. However there is now about 12 seconds of black screen at the end of the video, no music or anything.

Your video is a different length than your original screenshot. Are you sure the audio is the problem and not the video?
