Video file changes after it loads into a timeline... what is the deal

hey there... I am having some very weird issues when trying to add certain videos into a timeline...

for the fact that they will either...

1. change in length... or

2. the sound will not play

I can NOT understand what could be causing it.... I will record a video from my Moto Z phone in an mp4 format... and it will be at the length of, say, 49 minutes and 32 seconds... I transfer it to my Win 10 Home v.1803 HP Pavillion Desktop PC-570, i7-7700 CPU @ 3.60 GHz, 64-bit computer as I normally would thru usb... and will then test play the video in Windows Media Player and it plays as normal... so far so good... but then when I load it into MEP 17 into a timeline... it now suddenly appears as a 45 minute and 20 second video... it has subsequently chopped off the last 3 minutes... and it will not extend past the 45 minute mark... how frustrating... the file properties show it still at a 49 min. video... huh?????? I am at a loss....

another time I had loaded a different video... mp4 format... into a timeline and the audio would just not play... even though it plays in numerous other media programs... windows media player, VLC, iTunes, RealPlayer, etc... but just not in MEP 17... in fact the ONLY way I could get any work done was to use another program to "lift" the audio from the video as a whole separate file.... and then load it separately... to then have to take the time to line it up properly... etc... what an extra amount of work to do... again at a loss... so what is the deal here... I never remember having these issues with earlier versions of MEP.... can someone please share an answer on how to address these issues... I would be very much obliged... humbly... God Bless, Melo D

Hi,

Do you really mean MEP 17? Or is it MEP 2017? Use Help > About and tell us the exact product and version.

Meanwhile, one immediate thought: what messages, if any, did you get when you imported the video(s) under discussion?

And one other: can you reproduce this with a small video clip? If so, upload that to a host like Dropbox so that we can try it.

@Melo-D

. . . . I will record a video from my Moto Z phone in an mp4 format. . . .

In addition to Terry's comment, the most likely cause of the issue is that the mp4 video is variable framerate which will cause the shortening you are seeing.

Please use MediaInfo to analyze the video clip from the phone and copy the results from the Text view in MediaInfo and post them here.

If it is variable framerate then the video will need converting to constant framerate.

The audio issue may also be due to an non standard sampling rate - the MediaInfo analysis will also show this.
