Your question is: "Why can't I see an image in the preview screen, but hear the sound? Previously it worked normally and recorded the image as well."
If you have upgraded MEP 2020 to MEP 2021 and you have no picture, but you have sound, then there is a possibility, that your video card does not support Hardware Acceleration on display anymore.
You can then solve this by going to:
file / settings / program... (hotkey "Y")
Click on the tab Import/Export
uncheck the box next to: "Hardware acceleration on display, if possible"
Close and restart MEP 2021.
If all goes well, you should now have video and audio again.
jos olet päivittänyt MEP 2020:n MEP 2021:een ja sinulla ei ole kuvaa, mutta sinulla on ääni, on mahdollista, että näytönohjaimesi ei enää tue näytön laitteistokiihdytystä.
Voit sitten ratkaista tämän menemällä osoitteeseen:
I can totally identify with what you're describing, but if Timo (@Tim56) replaces his video card for a more recent video card, then hardware acceleration will also be supported again by Movie Edit Pro 2021.
Tim56 also has another issue not mentioned in this topic -
When I save movies to my computer, the only save format seems to be wmv. Is it so? Pretty grainy end result. How can I get a higher quality/sharper result (e.g. Avi)'
