Pixelated video on cuts, but not every time, whats causing it?

Hello, I have the latest version of MEP, and generally happy with it as an editor but finding Im having a picture quality issue when cutting from camera tracks to another. It also does it when scrolling through the clip using the mouse. It goes pixelated for a split second right on the join between cuts. But doesnt do it every single time. Which is annoying when you need to do technical and fast cuts, as I can only fix it by moving the cut one way or the other slightly. But this slows down the edits quite a lot as I need to check and double check every cut.

If it goes pixelated during a length of footage, it will render fine, but when it goes pixelated over a cut, it renders like it too, no matter if its on a DVD, Bluray or a video file.

The footage is all the same file format and nothing special, just AVCHD 1080i video camera files. All filmed 1920x1080 and the program settings are set to match. Changing them doesnt make a difference as Ive tried that.

Any ideas on how to fix it? Its a freshly built computer this year to well over the minimum specs, and freshly installed latest version of the program with current updates.

Any help would be great.

Nick

Hi Nick

. . . . Its a freshly built computer this year to well over the minimum specs . . . .

What are the computer specs - please quote the processor and graphics card/chipset make and model in full?

Can you post a screenshot of the Program settings, Display options tab and the Import/Export tab.

A MediaInfo analysis of a clip that is exhibiting this may help - post the results from the Text view in MediaInfo.

Thanks for the reply, please see attached pics for some more details. I have installed my previous version of MEP (2016) on the same PC, than runs the same video clips perfectly fine with no pixelating. However that version keeps coming up with audio download boxes even though Ive got the full program and it plays the audio fine.

I would rather just get the 2021 version to work properly rather than having to keep going from one to the other as either way slows down the edits. Everything else on the program seems to work as it should.

Any help with settings would be great.

Why in the first image, there is no interlacing, but in the third image there is?

@Reyfox

Assuming you are referring to the options at the bottom of the pane - these are for when analog recording from, for example, a USB video converter as would be used in a VHS transfer/conversion and determine whether de-interlacing should be used or not when live previewing or on playback.

The 3rd image is the properties of the video clip on the timeline and with de-interlacing set to automatic it will detect whether the video clip is interlaced or progressive, if interlaced de-interlacing will be used - monitors for example are progressive devices.

Could those settings be why Im getting this issue? What do I change the settings to? I have installed the same program, MEP 2021 onto my laptop and the same footage works fine on that, so it must be a setting thats wrong. Or is it a case of un-installing the program and starting again?

Hi Nick

Difficult to say if the two machines have different components.

Best to have both side by side and check the one that works against the one that doesn't alongside each other in the settings. Uninstalling a program rarely works to resolve a problem and often makes it worse leaving registry keys broken and maybe even bits of shared coded can either be left behind or deleted by accident when it is needed for something else as well. Sometimes the same settings will not work the same on two different machines.

Very unlikely.

Can you download and install MediaInfo, analyse a source video clip that is exhibits the pixellation when cut and post the results from the Text view - see this short tutorial if you have not used MediaInfo before.
