Hi

We need more information:

Computer specification, Windows version and program full name and version number - see this topic for specific details required.
The Export setting you used - a screenshot would help.
Do you have Calculate Effects on GPU checked in the Export dialog.
What effects have been applied to the video objects on the timeline

No effects have been applied just music. But without music the case remains the same - sound works but instead of video I see only this:

Thank you!

Hi.

You don't appear to have selected 'Export selected range only' nor ticked to use calculate video effects on GPU.

You also appear to have selected an m2ts file export.

Ray.

Also:-

The clip on your timeline says it has the HDR effect applied to it! Try removing the effect and see if this changes anything.

Exactly the same issue here. I get a green MPEG4 file if I export above HD 91920x1080), regardless of settings, when viewed in VLC Player. All files are fine viewed in Virtual Dub and VideoRedo.

What I've tried:

Main Concept and MEP Default MP4: both Green

Calculate Video Effects on GPU: results in a Zero Byte file Using the Main Concept codec, otherwise, no effect on the Green file.

1920x1080: all exports display fine in VLC Player. Any exports above eg 2720x1528 or 3840x2160 result in a green file.

HEVC codec: no problems, all files display fine in VLC Player, with Calculate ticked and without.

No effects on the video.

A sliver of real video is visible at the top of the green in VLC Player.

Note I am also on Win 10 20H2.

Example (aviation-related just for you, Terry!... if you can see it, that is):

Google is our friend. I found this:

How do I Fix Green Screen on VlC?

Open VLC media player, click on Tools from the top and choose Preferences from the drop down.

Now from the Simple Preferences window select the Input/Codec options.

Look for the Hardware- accelerated decoding option and set its status to Disable from the drop down.

That fixes it. Dratted Peewit...

Hello Ray,

Thanks for your answer. I tried out all of your suggestions but there was no change. Till now the only way to avoid green files to export vid as .wmv and play with Win Media Player (usually I use MPC-HC (x64)).

@blvigh

The green video phenomenon that I described above for VLC Player also exists for Windows Media Player and MPC. There are many posts on the web about it.

https://www.techwalla.com/articles/how-do-i-remove-a-green-screen-from-windows-media-player

I also note that Media Player Classic was last updated in 2017. Perhaps Windows 10 version ???? is messing up the acceleration aspect of video playback with MPC. In fact, the MPC homepage says:

"MPC-HC is not under development since 2017. Please switch to something else."

@johnebaker

John,

Do you have Calculate Effects on GPU checked in the Export dialog....

I have been intrigued by this option for some time. What exactly is the benefit/purpose of ticking or unticking it?

Cheers, Al

@AAProds

Hi Alwyn

. . . Do you have Calculate Effects on GPU checked in the Export dialog . . .

No I did not use it - the results depend on what effects etc are used in terms of time saved (if any) by using this option.

From the manual:

To accelerate exporting, you can let video effects be
calculated on the graphics card. At this time this applies to brightness, gamma,
contrast, colour, saturation, image size, cropping and position effects as well as various
fades and mixes.

John, sorry for being confusing, I just quoted you from an earlier post.

I guess that is typical Magix-ese; would it be fair to say they mean "you can let video effects be processed by the video card"? I struggle sometimes with the language used to describe a feature, this being one example.

Cheers, Al
