Error reading .webm format

[Airone]

Hi all,

Today I tried to import a .webm video file into my track, but there was an error:



Then I tried to view the video with Windows 10 app and had no problems. Has anyone had the same problem and/or knows how to solve it?
Thanks.

Hello RobertOZ,

thanks for the reply, but the only 'Open' existing in the 'File' menu is for the project. I can also insert a video in the library or in the video track, but in both cases the error is the same as above.

[RobertOZ]

Not sure what is meant by 'open" Select File/Insert media to timeline, find your video and select open

[Airone]

Of course I did so, there is no other way to do it. Is it possible that there is a limitation in the size of the images? This is a 4k video.



It is strange though that Windows 10 is able to reproduce it and Videostudio fails to recognize it.

Can you provide the link to that webm video that you are having trouble with?

[Airone]

I'm sorry, but it's too big (about 1GB).
This is the information that VLC gives me:



Is it possible that the VS Ultimate 2019 fails to process a 4K video or something bigger than HD?
?

The only thing that stands out for me in those Properties is the frame rate of 23.976215. I am wondering if it should be an exact 24 fps or even 25? VS as we know does not like video which uses slightly unusual properties...

Tried importing a 4K resolution Webm video constant 24fps, VS2019 crashed with "Corel Video Studio has stopped working message"

Robert -- can you please upload a 10 or 20 second clip from your 4K video please so I can download and try it at my end. I am having difficulty finding a 24 fps 4K sample via Google...

Hi Ken,
Video link as follows

Both VS19&21 get BEX64 crash with this
Fault Module Name: uvWEBM.vio
Fault Module Version: 19 or 21.0.0.68

No sound.

Shotcut get it OK. and few others also.
VMS16 do not support webm or vp8 at all

Thanks Robert. But yes, it also causes my VS 2019 (and 2018) to crash immediately and without message. Power Director 16, Magix Movie Edit Pro Premium, Adobe Premiere Elements 14 and (Vegas) Movie Studio Platinum 16 simply don't appear to accept .webm video.

Curiously enough, the el cheapo Ashampoo Movie Studio Pro 3 both accepted and played it perfectly. Go figure.

FWIW a standard def .webm file I had refused to open in VS 2019, but gave me a File Format Mismatch error message and did not crash the program.

I have this same problem, and now I have a mkv file that does open, but without any audio.
Best solution for me is to re-encode these problem files as mp4 by running them through "Handbrake".
Handbrake seems to be able to create a rock-solid video from any flubbed up source.
