Hi and welcome to the forum

In addition to @browj2's comment, we need more information:

1. Computer specification, see this topic for what is required and please quote processor and graphics card make/model in full. I would suggest you put this information in your profile signature so we do not have to keep asking for it.
    
2. Are the graphics card drivers up to date?
    
3. A screen shot of the Export dialog you are using.

Not trying to snag the thread but I cannot export to MP4 either, sometimes it crash sometimes it export but most of the effects are gone, almost ruined my day, exporting to WMV worked ok though.

I tried both GPU export (GTX 1080 TI, driver 456.71) and that lost most effects (90% of all move and size gone), trying CPU instead killed MEP (Movie Edit Pro Premium, 21.0.1.92 UDP3) just when the export had finished, MP4 file is there but it will not play, Ryzen 7 3700X, 64GB ram, I have only tried CPU and GPU yet, not OFF.

I never had any problems with previous versions on the same hardware, I just tried MP4 export with CPU mode again and this time it crashed after just a few seconds (no message or anything, MEP just gone).

Hi

The GTX 1080ti drivers need updating.

If you are not gaming on this PC it is recommended to use the Studio Driver which is currently version 472.47

If you are gaming on this PC the current Game Ready Driver is 496.76

I see from the export dialog that the Average Bitrate is set too low for FullHD (1920x1080) 30 fps - at a value of 6000 the image will appear to be softer and may exhibit compression artefacts, particularly where there is action in the scene, ie movment across or panning in the scene. Unless there is an overriding reason for using such a low average bitrate, the presets defaults should be used.

. . . . I have only tried CPU and GPU yet, not OFF . . . .

The 3 options should be GPU, CPU and Microsft WARP - the CPU option is the equivalent of OFF and the encoding may be vey slow.

Can you post a MediaInfo analysis of the exported mp4 that does not play - see this tutorial on how to setup MediaInfo and analyse the clip if you are not familiar with it.
