Hi and welcome to the user to user forums.

I'm going to guess this is screen capture of video game play. In which case it will be what we would call a variable frame rate file that the program can't be reliably replayed within a video editor as the sound is captured at a constant frame rate while the video part adds or reduces frames that match the speed of the action happening on screen.

So first the file must be converted to a constant frame rate using a file conversion tool such as Handbrake. That file can then be imported into the video editor and both the sound and video portions should be the same length ready for editing.

Ray.

24.0.1.199 (UDP3) is the version. This is a killer as many of our educational videos go past 1 hour in length.

As for the comment from @CUBEACE, this was not a screen capture. This was a video export from a Powerpoint presentation. Again, the source video plays properly in windows media player.

Also this is a much newer version that V17 that I was using. It always had the audio track displaying on this timeline. This does not display and I can't find any way to display. This is helpful for checking issues like this! Thank you

But, per @CubeAce I will try handbrake. I has a similar program years ago called MPEGSTREAM. I think it is gone now but it fixed lots of formats. Bottom line is you would expect Movie Studio...the 25th version...to do it properly? Thanks.

Hi.

Variable frame rate files often exceed or run under the normal video file frame rates of 24, 25, 48 and 50 frames per second or their NTSC counterparts.

Video editing programs are primarily aimed at videographers and export video at constant frame rates similar to those shot from dedicated video cameras.

The files made from other sources that can also include smart phone and action camera footage often have headers or code that cannot be read to recreate missing frames when the export may be of a higher frame rate, nor would such a program know where to take away frames that exceed the chosen export frame rate and keep it in sync with the sound track or make possible moving images move as expected without sudden jumps in the action.

Some systems with greater processing power in their GPUs cope much better at handling such files with their inboard processing so something like an nvidia 4090ti would tackle the task with more success than someone such as myself with an nvidia 3060. How successful really depends on how often, sudden and how large a frame rate difference occurs within the timeline.

For the majority of us mortals without such processing power we have to rely on such tools as Handbrake to convert variable frame rate files to constant frame rate files, but there are other conversion programs I'm sure @AAProds can inform you of that may be better suited.

Ray.

Thanks Ray. It is converting right now...on an old 4790K running intel 4600 graphics on the mother board. (Yes, you can cringe now!)

Funny, I now remember we ran into this issue back years ago and it was MPGStream that fixed the problem.

Hi,

Also this is a much newer version that V17 that I was using. It always had the audio track displaying on this timeline. This does not display and I can't find any way to display. 

If you don't have audio and video on separate tracks, go into the Program Settings, Video/Audio tab, and uncheck "Video/Audio on one track."

For anything already on the timeline, Ctrl+H will put Video and Audio on separate tracks.

Hi Richard.

No cringing at this end as I have often been reminded on these forums that just because a machine is older doesn't mean a project can't be completed. It just takes longer if you are stuck at the software level rather than benefiting from the latest hardware GPU AI cores or multi-core CPU performance. Even then it is not a given that any one file can be easily used.

Good luck.

Ray.

Also this is a much newer version that V17 that I was using.

@Richard-DeVito V17 ?, I'm guessing that is Movie Studio 17 which is Vegas Movie Studio 17.

Vegas Movie Studio & Magix Movie Studio are completely different programs, one is not a newer version of the other so you can't compare one against the other.

Well, lets see... We started with

Movie Studio HD 11.0

Movie Studio 13.0 Platinum

VEGAS Movie Studio 14 Platinum

VEGAS Movie Studio 17 Suite

and now Movie Studio 2025 Platinum

They push an upgrade promo email and who knows what cross version you are getting..seems like they have a product indentity crisis. WHICH programs should we be using to make editing educational medical videos easy?

Thanks!

@Richard-DeVito Vegas Movie Studio & Magix Movie Studio are completely different programs, there was no upgrade from one to the other, there was never any relation between the two whatsoever. Vegas Pro & Vegas Studio were bought by Magix, Vegas Movie Studio 17 was the last of that series, a short while after Magix renamed Magix Movie Edit to Magix Movie Studio & now offers that as the upgrade from Vegas Movie Studio (incorrectly). Vegas Pro continues to this day. The closest or correct upgrade from Vegas Movie Studio is to the current Vegas Pro.

Vegas                                               Magix

Movie Studio HD 11.0                                   Movie Edit 

Movie Studio 13.0 Platinum                                  I

VEGAS Movie Studio 14 Platinum                        I

VEGAS Movie Studio 17 Suite (Last one)             I

                                                                  Movie Studio 2025 Platinum

Vegas Movie Studio.

Vegas Pro 22 Looks almost the same as Vegas Movie Studio

Magix Movie Studio, like i say completely different program.

WHICH programs should we be using to make editing educational medical videos easy?

I'm just trying to point out that you can't compare one from the other, which one you choose to use is up to you, why your video won't work properly is another matter.

Thanks. Obviously they are cross selling and confusing the market. It also explains why the interface is so different.

Back to the audio issue. I imported ANOTHER video and this time no audio after 10 seconds. I then ran it through HandBrake and SAME issue. @CubeAce I am at a loss as to how to solve this. Thanks for any additional details!

@Richard-DeVito

Hi,

Have you gotten Video/Audio on separate tracks yet as I indicated?

John CB

Yes, Thanks. I did get that to work. It is possible that somethine is stopping the program from importing audio? I vegas, I remember you could stop rendering audio to a visual display, but that did not stop audio importing.

@Richard-DeVito

Hi,

Could you please post a screen shot of the interface? Optimize the timeline first so that we can see the full duration.

John CB

@Richard-DeVito

Can you also post any program setting images please similar to these two?

What are your audio playback preference settings for instance?

You should be using the wave driver rather than direct sound. Look at what sections I have ticked.

Are you missing sound or is it just not in sync? Can you see a waveform across the whole duration of the clip?

Screenshots as @browj2 suggests may help.

Ray.

@Richard-DeVito I'm not sure why nobody has asked for the MediaInfo of the video..

The App is called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish. https://mediaarea.net/en/MediaInfo.
After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, drag the edges of the window that pops up so it shows all the information & screen capture that page, post that image on here using the arrow button next to the smiley at the top of a new comment 👍

Or Copy & paste the information in a new comment like this

@Richard-DeVito

If it's not too big, I'd suggest you put the file up on Google Drive (or other file-sharing site) for us to analyse. It's often the quickest way to either verify there's either a problem with the file or Magix, or whether it is just a setup issue which we can guide you with.

@Richard-DeVito

Hi

. . . . This was a video export from a Powerpoint presentation. . . .

Can you clariy this please - Powerpoint has 2 methods of creating video files using:

1. File, Save (as) to create directly create a mp4 video file - this produces a Constant Frame Rate (CFR) video file which is the standard frame rate mode with no audio.
    
2. Record option to run through the presentation adding notes, highlights, audio recording etc

As you have commented:

. . . . no audio in preview after 1 hour. The original clip is fine. . . . .

This would suggest option 2 has been used, in which case you may have a problem.

The recording option is, as @CubeAce asked, 'in effect' a screen capture and produces Variable Frame Rate (VFR) video. VFR video is known to cause issues, usually audio sync, with many video editors.

Try converting the video file to CFR using a video converter such as Handbrake.

Thanks John. These folks are using newer versions of Powerpoint. They use Export > Create a Video > default options which are detailed here: Turn your presentation into a video - Microsoft Support https://support.microsoft.com/en-us/office/turn-your-presentation-into-a-video-c140551f-cb37-4818-b5d4-3e30815c3e83?ns=powerpnt&version=90&syslcid=1033&uilcid=1033&appver=zpp900&helpid=81683&ui=en-us&rs=en-us&ad=us

The only solution that worked was to use handbrake. BUT, I did find something interesting. IF I used Ctrl H and created the separate audio track and then displayed the wave form, it seemed to fix the issue. The problem was compounded as I would swap out videos and the new video would not load completely and we had to drag it open..very strange, but it looks like the program is storing the previous track length when it is removed and replaced. This is different than Vegas Movie 17.

@Richard-DeVito

Hi

. . . . The only solution that worked was to use handbrake. . . .

The Microsoft article you linked to cleary states in the very first line 'When you make a recording of a presentation' is what I suspected was being used, ie method 2 in my previous comment above which, in my experience, creates VFR video files.

If you are not familiar with PowerPoint, this a 2 step process, the first step is the creation of the slide show itself which has no narration, timing or animations, the second step being the recording of the 'slideshow presntation', where the narration, timing and pointer interactions are also recorded and to create a 'as presented' video for export as a video.

. . . . IF I used Ctrl H and created the separate audio track and then displayed the wave form, it seemed to fix the issue. . . . . but it looks like the program is storing the previous track length when it is removed and replaced

That is interesting and may require more investigation/testing.

Check in the program settings, Video/audio tab, that you have the 'Automatically create waveform during import' option checked (on) and the Video/Audio on one track option unchecked (off).
