I am trying to import an mp4 or mpg file into Cubase 10.5 and nothing happens.
It feels like I must be doing something simple that’s wrong - can anyone help please?
Thank you for your response Martin - I have looked at the list of video formats and extensions and clearly my file is not in a supported format, though I find it hard to understand how to fix it. I have used VLC to convert the file using the H264 codecs profile, but clearly there is some change I need to make that I don’t understand. Can anyone recommend a VLC conversion profile that will work please?
Here is the spec of my file from Mediainfo. The file was produced by the Windows 10 Camera App:

Hi,
I’m sorry, myself I’m not in video at all Hopefully someone else will help.
Try changing the frame rate in VLC to 29.97
Hi,
You are totally right.
Sorry, I deleted my post to do some research, but not fast enough! Anyway, Martin confirms. 
Thank you everyone - I have converted to constant rate with Handbrake and the file loads fine…except, audio is now out of sync………
I will avoid using the Camera App in future.
Your help is much appreciated
Jim
You should check out this app, it converts videos to a format Cubase will handle, it is written by a Cubase/Nuendo user. Highly recommended.
Thank you very much Steve - I’ll try that next, looks extremely good
I have used ER toolkit for a couple of conversions, both easily and successfully, and am able to import them into Cubase.
The converted videos play just fine in VLC with sound well synchronised but not so in Cubase. Cubase happily imports them but the sound is not in synch in the video player.
I have since imported other videos (not created with variable frame rate) and they play with sound synchronised both in and out of Cubase.
I’m at a loss with this - the simplest option is for me not to use the Webcam for recording, which is a shame as it is pretty good quality on this Lenovo i7 laptop.
However… I found that if I export the video from Cubase - it plays outside in Synch! So could it simply be that the Cubase video player has trouble keeping up with the display but the editing actually functions OK?
I’m grateful to those who taken trouble and helped with this - I’m not necessarily expecting a solution but all comments welcome!
Variable frame rates are not supported, as they state on the page linked above, so you have to convert accordingly, or configure the source to conform.
Did you try the ProRes conversion in Er Media Toolkit?
We are having the same issue with importing video into Cubase Pro 10.5 on Windows 10 home.
Our videos were taken with a Pixel 2 and 3. Turns out Google just wont offer the option of a stable frame rate. Doesnt matter that all the extensions and numbers match up.
So what I need is a good suggestion for an easy converter (by someone who is using it for same purpose and knows it works)
anyone?? thanks kindly.
Are you reading the thread?
Hi - if its any help, I can vouch for that app that’s in this other thread where you posted:-
Good luck
Bob
These are the settings I use with good success
I have the same result with Pro Res. I have tried it on a second machine with the same result.
For the time being I will avoid recording with the Camera app. Shame.
I really appreciate the help.
XMedia Recode can probably do the conversion, but it’s fiddly.
Could be sample-rate mismatch…
