The video effects no longer work after I updated VLC this morning, I have tried closing the application and opening it again, and I have restarted my pc multiple times. Still no effect, please help.

Yep. I'm having the same problem with the 64 bit version on windows 7, & W 8.1. It's real buggy. 3.0.3 was almost unusable except when using basic default settings, even when playing quite ordinary mp4. Setting brightness, contrast, color, hue, or sharpness do all sorts of crazy useless stuff if I try to use them. No matter how I set them, they don't work properly, & videos look absolutely terrible. I had to downgrade back 2.6.0 to fix it.

Same problem here.....did not matter what I did, no picture....audio fine but no picture.
I had to go back to an older version.....very disappointed here....cannot get any help with this issue.

Disable hardware decoding in preferences.

Disable hardware decoding in preferences.

I tried doing and then the application just crashes with no effort whatsoever.

Just to clarify, Hardware Acceleration is not in VLC 303 Preferences. There used to be such a button in earlier VLC, called "Overlay", but I don't see it anymore. There is also Hardware Acceleration in PC setting that you can access through Display Properties-->Troubleshoot. My old video card has no button "Troubleshoot" in Monitor Adapter window, so this can't be changed.

I am running VLC 303 under Kodi, in Win 10, for old shows and movies on 720p TV. Don't care about 4K or 8K - don't even know what they are. Old video card was playing fine with previous versions of VLC, then suddenly a problem with VLC 303. VIdeo doesn't open - but sounds is playing - until I click on VLC tray icon at the bottom of PC screen. Have checked everything in Preferences, including "video always on top". On newer Win 10 machine - that I use for work, not for movies - VLC 303 runs fine. So... while admitting the very old age of my machine, I confirm that VLC 303 has some issues.

Hardware-accelerated Decoding is in "Input/Codecs" of simple preferences.

This fix seems to have fixed the problem for me after updating from (VLC 2.x) to (VLC 3.x)

I modified the following settings:

Preferences -> Inputs & Codecs -> Hardware-accelerated decoding to -> ( DISABLE )

Preferences -> Video -> Output to -> ( Direct3D9 Video Output )

I hope it works for you.
