Video clip length incorrect

gav-r wrote on 9/27/2016, 4:13 PM

Hi all.  Can you help.  I just started using Sony Movie Studio 12 Platinum.  I have some video clips that I recorded with my Garmin virb and when i add them to the timeline the video track length is wrong.  Hopefully you can see the image I attached - the highlighted file is 00:00:06;13 seconds long.  In the summary below the selection window it shows the audio track length correctly but it shows the video track length as 00:03:31;11.  When I add the clip to the timeline the audio track is fine but the video track is way longer than it should be.  See the second image.  Some of the video clips are correct, others are wrong.  How can I fix it?

Thanks

Is this the only file with this error? Is there video after the 6:13 mark?

No, lots of the files have the same error

...and no there is no video after the 6:13 mark.  The clip plays ok, video and audio in sync just that the video track looks longer in the timeline.

I would guess that your camera is not putting correct metadata for Movie Studio to interpret. You might go to the Garmin site and see if others are complaining of similar issues.

I just did a test.  The Garmin Virb XE has 4 different fps settings... 50, 48, 25, 24.  I shot a test video in each setting.  The clips at 48 and 24 fps show the correct video length in MS12.  The clips at 50 and 25 fps show the wrong video length in MS12.  So now I know.  Trouble is, I have about 5 hours of video clips from a holiday that all show the wrong video length.  Is there any way to edit the metadata?

I found a workaround.  If I load the clip into Garmin Virb Edit then export it, MS12 then sees both the video and audio track as the correct length.  It will be a pain to do all the clips but at least it will work - unless anybody can find a better way.

Hope this helps someone else.

I can't see your images (I think the forum's image-server is slow, but it might be my connection), but this sounds like this bug: https://www.vegascreativesoftware.info/us/forum/gh4-footage-import-problems--97413/

This is fixed in VEGAS Pro 14.0 (Build 161) so presumably it will get fixed in a future version of Movie Studio, but you should submit a support request anyway at https://support2.magix.com/customer/en/vegas/form to make sure it gets into their database. Unfortunately the "fix" using Warper's script described in that thread will not work in Movie Studio because it doesn't support scripting.

Quote from the VP14 b161 release notes: "Fixed a bug that could cause inconsistent audio and video stream lengths when working with some MP4 clips."

[EDIT] Nick's response is probably the correct one.]

 

Probably it is vfr and is being misreported by Vegas.

One thing you can try is Media Properties set to the proper frame rate, not 100fps or something equally ridiculous.

Maybe the best thing is to convert it using a vfr friendly encoder.
