I have a mp4 video that I am trying to edit. When I add this or any video into my timeline and attempt to preview I get a black screen and can hear the sound. I can clink and move the the video forward and see it moving but once I select play the clip changes to black and only hear the sound. In researching I installed all the patched/updates. I have ensured the check boxes on the time lime are selected for both the audio and video. Someone had mentioned in the forum to unchecked the boxes for the hardware acceleration under preferences. Please advise. I have both Power director 14 and 16 and neither will work.

If you upgraded your video card drivers, go into Device Manager, Video Card, Reverse Drivers

Hi Cindy

You dont make it clear if you have actually tried unchecking HA in preferences. If you haven't, try it. Unchecking HA can often cure the strangest things.

Good luck

Okay I located the drivers for my video chipset and there is not an option for rolling back the drivers.

Does the MP4 clip play on any other player such as VLC player or similar? If you havent tried it, give it a go.

Yes the only problem is while trying to view the preview when editing. I have played the video on other players and have produced videos from Powerdirector that work fine. It is just the preview.

Just had a thought. Have you unintentionally unticked the video track in PD?

No I do not believe I have any codec installed. The link of a video I downloaded is here. I downloaded it converted as a MP4 made its with the preview not working properly (black screen) and made the video at this location.

Location 1 source-

https://www.youtube.com/watch?v=vH8hgfAhldI


Location 2 what I created-
https://www.youtube.com/watch?v=8GDnZAscl6Y

Earlier today I made a couple of mp4 videos using my phone and its the same no mater what I use.

It seems to be just the preview function

Thank you

If you did update video drivers and then had this problem, and have no way to revert the drivers, try to uninstall and reinstall the ones you know worked.

In my case I have to use old drivers because the new AMD R9 drivers does not work with PD16 or PD17 I already tested it yesterday.The new Driver looks good for other applications.

I do not believe the drivers have been updated

Capture a screen of the occurrence with PD16 and post here, maybe we can see something that helps.

I see you are using shadow files. Try without. If that works we can discuss why.

I unselected the shadow files and I am still having the same issue. If I pause the preview of the video it does show me a picture of the present location of the clip. When O press play again the preview goes to a black screen agin and I can hear the sound.

Thank you,
