Make sure there is a "VegasEffects.fio2007-config" in your VP install directory like "C:\Program Files\VEGAS\VEGAS Pro 18.0" before you launch VP.

I have it here tho

Open "VegasEffects.fio2007-config" with notepad. You will see something like:

"[FileIO Plug-Ins]
VegasEffectsFileIO=C:\Program Files\VEGAS\VEGAS Effects\VegasEffectsFileIOPlugin.dll
[VegasEffectsFileIO]
Reader={0165FD16-2597-4680-87E9-720A5CCFAC63}
{0165FD16-2597-4680-87E9-720A5CCFAC63}=1
"

You need to make sure there is a "VegasEffectsFileIOPlugin.dll" in the path above in your computer, for example mine is "C:\Program Files\VEGAS\VEGAS Effects\". If not, you should change the path above to right path of your "VegasEffectsFileIOPlugin.dll".

After that, you are supposed to import ".vegfx" correctly. Meanwhile, you will find a "VegasEffectsServer.exe" PID in task manager near "vegas180.exe". This "VegasEffectsServer.exe" means the feature importing ".vegfx" is functioning.

Mine says

[FileIO Plug-Ins]
VegasEffectsFileIO=C:\Program Files\FXHOME\VEGAS Effects\VegasEffectsFileIOPlugin.dll
[VegasEffectsFileIO]
Reader={0165FD16-2597-4680-87E9-720A5CCFAC63}
{0165FD16-2597-4680-87E9-720A5CCFAC63}=1
 

And the "VegasEffectsFileIOPlugin.dll" is located at C:\Program Files\FXHOME\VEGAS Effects\VegasEffectsFileIOPlugin.dll

All of this in correct path, yet I cant import VE file into VP, why?

I suggest you should re-install VEGAS Effects.

Been there & done that. Still the same.

But to make things more interesting, other clips/projects I can send the media to VE with no problem.

It only specifically bug on this clip. Here a download link of the video I shot couple months ago. Its the same clip where VEGAS Pro displayed VE project missing on my previous project.

Successful without trouble...

Put the C0019 clip to VP18, then right click > Edit in VEGAS Effects. No trouble at all.

That is weird. I can't have this media sitting in VE, otherwise VP wont import at all.

stupid way - try rename the media to something else...

or, render to Magix Intermediate, and see if now you can do send to VE.

Already rename the media, but Haven't tried transcoding it.

Just a guess, you video is AVC+PCM (lossless audio format). This match (AVC+PCM) is not common so your VEGAS Effects can't import it, so your vegfx file is damaged.

You need use handbrake or Xmediarecode or something other to reserve the AVC and convert PCM to AAC;

Or you can install codecs pack such as k-lite to make VEGAS Effects import AVC+PCM. (I have installed k-lite, so your file in my VEGAS Effects function normally.)

I try closing VP18, and rerun, even restart my system as well - in case the problem is in the next session... but no - no issues.

If AVC+PCM (XAVC-S/L format?) is the problem... how about other clips? is it the same codec?
