VSX9 oddity with Duration, Total Frames and Frame rate

[WarpObscura]

When I attempted to import a video file to VSX9 (19.7.0.12 64bit Ultimate), I got as its Properties a Duration of 1.704 seconds, Frame rate of 90,000 fps and Total frames being 153,342 frames.

The strange thing is that when I hover over the file in the import dialogue box, the Length correctly displays as 1+ hour.

The file in question is a downloaded MP4.
H.264 High Profile Video
24 bits, 1920 x 1080, 16:9
Data rate: 2654 Kbps
MPEG AAC Audio
306,990,080 Samples
48,000 Hz, 16 Bit, Stereo
Bit rate: 241 Kbps

File size: 2.16 GB - Could this be the problem? Does X9 have problems working with video past a certain file size? I have successfully imported and edited ~1 GB video.

No error messages were generated.

Split by Scene scan confirmed the above: 153,342 frames, Duration of 00:00:01:63342.

Video file in question has been successfully run using Films & TV, MPC-HC 64bit, Windows Media Player without issue, playing for the correct length of time.

Hmmm. never had this experience, so I am going to give you some ideas. It seems this could be a bug, and I wonder if X10 handles this file.

An idea is to split the file in the middle and see if the properties of each piece now are stated correctly.

I agree that it sounds very odd. VS X9 (and other versions) would normally have any difficulty with a file that size or larger.

In the VS Preferences > General, have you ticked the box beside "Show message when inserting first video clip into timeline"? If so, and with a New Project, did you get the message asking if you wanted the Project Properties to match those of the clip? If so, did you OK that and are the Project Properties the same as the VS false Properties or the same as your legitimate Properties?

Have you tried to output a new clip using your correct Properties as the settings? If so what did that produce?

The only other thing I can think of for the moment would be to use a third party video conversion program such as Handbrake to produce a new mpeg-4 from you video and see if VS then gives correct Properties for the new video.

WarpObscura,

could you post the link to the file so we can download and test it?

Could you download MediaInfo and use it to check the files properties? It is much more "reliable" then VS.

It still gives the ~1 second to both, I'm afraid.

Did you mean "would not normally"?? Would you know where else I can get open source GB+ size video so I can test whether file size might be a factor?

Yes, I did tick. I got that message. When I OKed it, it gave me the false properties.

When I tried to output using the correct properties, it still gave me ~1 second Duration, but the Total frames reflected ~40 instead of the original 150k+.

Will try Handbrake and get back to you on this.

Hi

The MediaInfo shows a variable FRAME rate. This very likely the cause of the problem. Convert to fixed FRAME rate using Handbrake.

John

[Ken Berry]

Yes, I noticed the variable frame rate too. Do you know if the video was taken on a modern smartphone, as they seem to like using variable frame rates -- though the length of the video suggests it might have been a different type of camera. Video Studio has difficulty handling them, preferring fixed frame rates which conform to international video standards.

And yes, I meant to say "not", above. Many of us here regularly edit files which are larger than that.

Yup, converting to fixed frame rate let it work just fine! Thank you for the suggestion!
