Hi guys

I've captured a video of a game emulator playing a game using windows 10 game bar capture.

The file captured by Microsoft's  own screen capture utility is in MP4 format. It is about 1 hour 15 mins long and plays fine in Microsoft media player and also VLC media player. Only problem is that Pinnacle Studio 15  doesn't play it correctly in the video editor. The video itself is too fast ( possibly three times the speed it should be ) and the sound lags the video. The sound is played at the correct speed. Due to this problem I am unable to edit the video. I've tried using slow motion ( by adding a speed effect  ) on the the video but still can't get an exact match with the audio due to sync problems.

I've also tried downloading the free trial of the latest version of studio only to encounter the same problem. Windows's 10 own Movie Maker sees the mp4 file correctly and plays it back at the correct speed. I've tried the MP4 video file on a Linux system and  VLC on Linux also plays it back correctly.

I'm guessing this problem is unique to Pinnacle Studio and there is an issue of the video/audio format  created by Microsoft Game  Bar capture. The game I captured was running on a commodore 64 emulator - the video created plays ok in Windows Media player. Anybody have any idea how I get round this?

I tried converting the MP4 file to AVi in tyhe hope that would fix the problem. I had the same issues ( Video too fast and Audio lagging ) with the AVi file as well.  

Hi and welcome to this forum.

Would you give a shot of Mediainfo to this file and post here a screenshot of its tree view ?

Thanks for the welcome Saby

 Here's a couple of screenshots of the file details extracted from windows File manager properties and VLC media data info. I'm not sure what you meant by Tree view or how to go about getting that info.

 Thr MP4 file captured is unique and I'd like to be able to edit it rather than try and re-capture the video again  using another method other than use Microsoft screen capture utility.

I'm guessing I may have to convert this MP4 file to another format. Possibly split the Video and Audio and save each separately. Hopefully, there is a work around?

Thanks for the Welcome Saby

Using the mediainfo app - Here's the tree view as requested.

I also posted a copy of the mp4 file info from VLC  media player - but it is awaiting moderator approval.

Ok, that's exactly what I was guessing : a lot of "mess" in the framerates (both video and audio) of this video.

Video framerate is variable, and its min, average and max values are very odd.

Audio framerate is very odd too and do not match the average value of video framerate.

Not surprising that a video editor is facing issues to synchronise video and audio streams.

You may try fixing this by transcoding your video to a constant framerate using an external tool like Handbrake.

Yeah - I knew this was going to be fun 

Windows own video editor loaded it ok and plays  it back ok.  I tried a couple of free Linux video editors and they could see it ok.

I did try to convert to AVi with no luck. 

I'll try handbrake as suggested - what option or video conversion do you recommend I try first?

Handbrake did the job !

It took me three goes before I got it right though 

 Thanks Saby

Thanks for reporting back.

You are very much welcome Saby.

 It worked a treat and saved me a whole lot of time. Nice one !

PS - I'm very impressed with the Trial version of Studio.

I'm working on a video showing a demo of an old C64 Computer game I wrote back in 1986-1987. The 3D effects work a treat and have brought a new dimension to the Game Demo.

It can be hard work learning a new software package but in this instance I'm willing to give it a go and upgrde from version 15 to the latest version. 

All the best Guys 

2 tips :

• if you purchase PS23 at Corel eStore, you get a 30 days money back guarantee. There is no risk to upgrade your PS15 to PS23
• select the upgrade version. It's the same as a full version but cheaper
  

Sorted !

 I'm the proud owner of PS v 23

The full version had no trouble handling that strange mp4 file that was out of sync. I'm guessing the trial version had limited capability on the input video files it could handle.

First impressions - very, very good piece of editing software for the price you pay.  It's quite a learning curve though  - not as easy to use as PS v 15  was - but far more capable.

Cheers
