@Peter-Resch could you provide a sample piece of media that exhibits the problem you are having?

Not sure how to do that.

Anyway, I installed Vegas Pro 20 on my ThinkPad laptop as a trial and it imports any .MTS video files no problem. It's only on my main desktop PC that this occurs.

Looking around the forum I notice that KERNELBASE.dll has been the cause of intermittent problems importing .MTS files (and rendering) at least since Vegas Pro 17.

@Peter-Resch Really important to get the developers the info they need to resolve problems in Vegas. You can use a service like Google Drive, Dropbox, Box, etc. and just share a link to any piece of media shot with the same settings.

Kernelbase is part of Windows so I don't think that narrows it down any.

Here's an .MTS file: https://drive.google.com/file/d/1Bnlbae0J9_zhRvwDRxTlpgmFPHm1le7x/view?usp=sharing, I hope it works.

KERNELBASE.dll is a Microsoft dynamic link library file and I suspect that Vegas Pro uses some of the functions and procedures in that library. If part of the file is corrupt or has been modified then when Vegas Pro tries to access some function or procedure then, as in this case, Vegas Pro crashes. Good programming should be able to handle it but I guess in this case it isn't.

Historically MS DLL's have been a major headache for programmers, particularly when there are multiple copies installed all over the place in a PC.

Anyway I can work around the problem by converting all my .MTS files to .MP4 files with Handbrake so don't worry about it. I'm sure my next Windows re-install will fix it if Magix cannot.

Thanks for the file.

FWIW it worked here on my laptop (Intel HD 630 iGPU doing decoding). It opens with compoundplug.

Could it be another situation where a GPU driver needs updating?

Could be. The AMD drivers are here. The R7 200 series looks like a line rather than a specific GPU so I couldn't link directly to a driver page.

Defiantly an issue with Peter's PC, works fine here. Nearly all Kernalbase.dll issues are driver related as Vegas is trying to implement an action and windows says no.

Standard interlaced AVCHD video.

Having an all AMD computer (sig below), no problem bringing the clip in and playing it back. I have many old MTS from my Canon camcorder and they too all play back and are editable in Vegas 20.

Your graphics card is from 2013, and not really considered "powerful", but a low end card. I think the card is a R7 240, at least guessing with the info @Peter-Resch provided. All this leads to me believe that while your CPU is adequate, your GPU isn't. This setup might be fine for Vegas Movie Studio 11 which was released in 2011, that card does not meet the requirements posted on the Vegas Pro website for Vegas Pro 20:

AMD/ATI® Radeon with 4GB and VCE 3.0 or higher

The R7 240 only has 2GB of RAM, and VCE 1.0. Looking at the R7 265x, it too has only 2GB RAM. The latest drivers can be found HERE.

@Peter-Resch

As a diagnostic technique:

Disable GPU Decode and GPU Acceleration in Options/ Preferences...

If the files load properly with the GPU turned off, go on with your work while you look for a more modern driver and/or GPU. Many people edited MTS files without a fancy-smancy GPU.

what card?
