Videostudio ultimate 2018 H.264 issue

[band]

I'm having issues with importing MP4-files from a friends DV cam (unknown model) into VS. Found some similar thread discussing crashes but that doesn't exactly match what I'm seeing.
When importing those files VS freeze. Task mgr says app not responding, VS consumes some 60-70% cpu and if importing vids by drag'n'drop, the explorer window freezes as well. I have waited some 5-10 mins before killing it.

The files i'm importing are identified in VLC as

H264 - MPEG-4 AVC (part 10)(avc 1)
1920x1090
FPS 50
Decoded format format: planar 4:2:0 YUV

Oddly enough, importing files from my xperia phone of the following format has no issue whatsoever (from this output, only the fps differs):

H264 - MPEG-4 AVC (part 10) (avc 1)
1920x1090
FPS 29.527928
Decoded format: planar 4:2:0 YUV

If using the "browse media files" function of VS and selecting "info" for the file, it shows up as H.264 Main profile video, upper field first but 25fps, not 50 as VLC says.

I have tested this on 4 different setups:

1. Windows 10, i7-4770, 16G, nVidia driver
2. Windows 10 laptop (pretty freshly installed), i7-8550u, onboard intel gfx
3. Windows 7, i5-3570K, 16G, newly installed for this purpose
4. Windows 7, VirtualBox, newly installed for this purpose

The three physical boxes have the exact same issue - however, running in VirtualBox works which would indicate some kind of hardware issue. I have tried to disable all the hardware acceleration settings in the preferences -> performance tab but it makes no difference.

Don't know if this could be a codec issue and I don't know what codecs VS uses (are they provided by Microsoft or by VS?)
Playing the file in e.g. Windows 10 media player works. One idea would be to convert the files somehow. Importing and sharing the files to MP4 / H.264/25fps using VS in VirtualBox produces files that can be imported into VS on the other boxes but that takes ages. I'm in a bit of stress since I have to finish a movie for a wedding the next weekend and just bought VS for this. Too bad I bought VS before obtaining the DV files from my friend... :/
I'm considering other programs but I've always used VS and have been very satisified in the past.
Happy for any advice - thanks!

1920x1090? Did you mean 1920x1080?

Do the files play in Windows Media Player?

Might have to use Format Factory or some other converter app to convert the video files until we can figure out what the problem is. It would be better to get Mediainfo list of file format details, in particular bitrate and audio properties.

It would be nice if you could place a small sample of the video in a cloud drive so forum members can try to help you.

It would also be useful to know exactly how you are importing the video into VS. Normally, such video is on a card in the camera and you don't need to use "import" at all. You simply plug the camera into your computer via a USB cable or else put the card into a card reader connected to your computer and simply transfer the video files using Windows File Explorer, the same way you would any other file. Then once transferred you simply open them in VS for editing.

(The foregoing assumes that your calling the camera they came from a "DV" camera probably means to you something like "Digital Video". In reality a DV camcorder is a particular type of camcorder which only records in the DV/AVI format onto a tape in the camcorder. The HD version of such a camcorder is called a HDV. But in both cases the properties of the video are quite different from those you give for this video.)

Thanks for your replies! Even though I finished the editing a couple of weeks back I thought I'd drop off some feedback in case someone else runs into the issue. There were some very hectic weeks to finish the editing and I got totally fed up with it, hence the delay

I don't have that many more details but the theory that it was VirtualBox that was the difference that made it work seemed to be incorrect. After applying all the patches from Windows update to the Windows instance in VirtualBox, the same issue appeared there as well - this would instead indicate that the issue might be in some codec that's bundled with Windows. Just guessing though.

I seem to have gotten the lingo wrong regarding "DV" and "importing" - I don't know what cam my friend used and how he exported the videos, I just got the mp4-files. When I said "importing", I basically just meant adding them to the timeline in VideoStudio.

To answer some of your questions:
- VLC actually reported the vid as 1920x1090 - some bug there as well
- The files played without problems in the windows media player
- I haven't tried Format Factory so I have no info about stream properties it reports

Anyway, I worked around the issue by converting the videos using the functioning installation of Videostudio in VirtualBox. I just converted them to mp4, 1920x1080, 25fps.
This is hopefully a rarely seen issue that can be worked around by converting the vids (perhaps using the suggested Format Factory.)
