extreme aliasing

Former user wrote on 6/10/2023, 2:23 AM

@Emptyflight Hi, you need to give info on your PC, which software & what the media is, there's an app called MediaInfo but It might be easier if you share a short clip on Google Drive or a similar file sharing site, use the chain button at the top of a new comment to post the link.

There's an App called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish. https://mediaarea.net/en/MediaInfo

After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, Copy & paste the information in a new comment on here 👍

@Emptyflight

Welcome to the Magix user to user forums.

In addition to what @Former user has written, you've chosen Movie Edit Now as your product. Is that correct, or do you actually have Movie Edit Pro, now called Movie Studio? There is a very considerable difference in features and facilities between the free MEN and the paid-for MEP/MS and might well have a bearing on the problem you are seeing.

If you do have MEP/MS please also tell us exactly which version and edition.

And yes, you are right I am not using Movie Edit Now, but I couldn't find a button for my program. I am using Movie Edit Pro Plus 2022. As I said, it has worked fine up till now, accepting a mixture of 4k clips from my Sony Action Cam, my Panasonic 4k Video Camera and from my phone.

hi Ron.

Sorry but you haven't shown us which graphics card you have.

I also notice the file says it is on OneDrive. If that is on line rather than in your computer that could be a problem.

Ray.

@Emptyflight

Thank you for the additional information. I have now moved your post to the Movie Studio area of the forum.

With apologies but I have edited your post to remove two sets of data which could allow your computer to be compromised.

In addition to what @CubeAce and @Marc-Goder have written, I note that you are currently running a version of Windows 10 that is "old". Is there any reason why you have not updated to version 22H2?

Jeff

EDIT: I downloaded your original file, opened it in Movie Studio 2023 Suite and it ran perfectly, no pixellation, tearing or other problems!

Former user wrote on 6/10/2023, 4:58 AM

@Emptyflight Hi, sorry that file looks & plays fine, variable can play slower but you shouldn't get aliasing like in your other vid & you shouldn't have to recode it. there is a lot of static on the audio tho.

Check you graphics driver, If it's a Nvidia driver you can use Nvidia Geforce, use the Studio driver but it seems people on here prefer the Gaming driver, you can try both with the Geforce app. https://www.nvidia.com/en-gb/geforce/geforce-experience/

This is the orig on my MMS2023, plays fine but with the static on the audio that i mentioned

Former user wrote on 6/10/2023, 5:15 AM

@johnebaker Hi, didn't know which thread to post in, following on from the other thread about mono & C for centre etc., this clip shows two channels LR in MediaInfo, Handbrake says 1 audio tracks, Vegas shows two different channel waveforms? (it has a lot of static in Vegas too)

johnebaker wrote on 6/10/2023, 7:25 AM

@Emptyflight, @Former user

Hi

The sample video clip exports fine from MMS 2023.

If the source video clips are on OneDrive this is not conducive to video editing, the program needs to write temporary files to the same folder as the source video clip, additionally the program will be waiting for video to be downloaded from OneDrive and depending on your Internet connections speed this could cause the issue you are having. The source files should be on a local, preferably internal drive.

Gid:

. . . . use the Studio driver . . . .

Magix recommend and test using the Games (GRD) driver - I received this info from Magix and I no longer recommend using the Studio driver - I changed to the GRD driver.

. . . . this clip shows two channels LR in MediaInfo, Handbrake says 1 audio tracks, Vegas shows two different channel waveforms? . . . .

The Xiamo clips audio is stereo - Handbrake and SF Studio confirm this

Which version of MediaInfo are you using?

. . . . it has a lot of static in Vegas too . . . .

I am getting no static - just a lot of gusty wind in MMS, VPX and Vegas Pro 14 peaking a -0.8dB is VP 20 overloading or apply a gain factor on import?

@johnebaker Hi, sorry it was early for me & i was looking at the Source at the top that says 1 audio tracks, 🥱🤦‍♂️😁

That does remind me of something on that other thread tho. I'll post on there for that ..

MediaInfo 23.04, I think it's the latest,

Do you not get the crackling?

I can see the spikes on the wave were the cracks are. I've marked them in red

Former user wrote on 6/10/2023, 8:12 AM

@johnebaker You've edited your comment,

. . . use the Studio driver . . . .

There's meant to be a ' I ' in there making 'I use the studio driver', that's why i followed it up with 'but it seems people on here prefer the Gaming driver', I didn't know about the Magix recommendation.

As I'm getting older i find I'm missing complete words out of sentences, even reading it back before posting i don't see the mistake, I think that's because speed reading I'm seeing what i want & not what is actually there, my mind sort of fills in the blanks 🤦‍♂️👴😂🤷‍♂️

I missed a paragraph out, you must have read immediately after I posted and had spotted the missing paragraph

Your not the only one - speed reading, and typing, are something I have to be very careful of.

I can see the 'spikes', however I do not hear them as you do in you screen capture. There is a 'pulse at 01.060 -01.065 (SF timescale) that can be heard.

I am overwhelmed at the number of people trying to help me. A thousand thanks!
I am not very knowledgeable about computers and programs, so I'm just trying to blunder through the suggestions as best I can. Here is what I've done:
I checked and my graphic card is a Radeon RX 560 series. Probably not very modern or efficient, but it has worked fine up until now. Mostly.
I moved the video clips from OneDrive to my internal hard drive. This didn't help.
I updated my system to Windows 22H2. This didn't help either.
I converted the file to an MKV using HandBrake. My Magix editor just showed darkness - black. Nada. The audio was audible though. And yes, there was a lot of wind - my son and I were hiking in Ireland and it was very gusty.
I converted the file to an m4v using HandBrake. This worked.
I have no idea if this solution is in fact a solution or a workaround. If anyone has any more suggestions (that a dummy like me would understand) to have this permanently fixed so that I don't have to run my videos through HandBrake, I'd appreciate it.

Thanks again!

Ron

@Emptyflight Hi, if recoding works for you than that is a solution, but for me it is never 'the' solution, it is a work around because you're skirting the issue of why your PC/software won't work with that file, I think you know that tho,

Despite 3 of us saying that your file plays ok I suspect there is something odd about it, everything in the MediaInfo looks just like my files except the colour/BT stuff at the bottom, like BT601 not 709 🤷‍♂️

Mocha Pro only imports the video, I don't know what it does with or how it separates the audio from the video but it gives me this, I've never had a prob with variable & constant? I migt ask Boris see what they say?

Silhouette is similar, it deals with video only not audio, that just loads a blank screen

johnebaker wrote on 6/10/2023, 2:26 PM

@Emptyflight

Hi

Can you post a MediaInfo analysis of the MKV clip - this may gives us a clue to where the issue is, also which export preset did you use in the original export that was bad, and did you change any of the parameters?

Thanks

John EB

Emptyflight wrote on 6/11/2023, 2:58 AM

Hi John,

Thanks for your efforts. Unfortunately, I deleted the MKV clip after it didn't work. But if I remember correctly, I tried my "normal" preset, which is H.265 60FPS PFR, all filters off but default interlace detection, peak framerate, constant quality set at 24 (whatever that is), Audio: AAC bitrate 160, stereo. I suppose I should have tried adapting the mkv framerate at least to the clip's framerate of 29.97, but as I've said before, I'm just fumbling about in the dark here in the hopes of a happy coincidence.

Emptyflight wrote on 6/11/2023, 3:06 AM

BTW, I just tried changing the framerate to 29.97 and the same thing happens: I can play the MKV fine with, for instance, mediaplayer but Magix just shows me a black screen. Oddly enough, when I start the "new project" it asks if I want to adjust my video settings from 3840x2160 29.97 fps to 3840x2160 29.97 fps. The program doesn't recognize that the clip and the default setting are the same. Is this normal?

johnebaker wrote on 6/11/2023, 4:37 AM

@Emptyflight

Hi

What is the mediaInfo data of the MKV file you can play in media players yet is black in Movie Studio?

I suspect the Handbrake conversion preset used was an unsupported codec eg VP9, the source video is h.264 (AVC).

Try converting using the appropriate 4K UHD (2160p) h.264 preset. On the Video tab select the Constant framerate option, the parameters for resolution and framerate should match the source video, if necessary adjust them to match - do not change the CRF setting.

@Emptyflight

Your video plays and exports perfectly here as well but I'm a little confused.

Do you mean the video plays OK in the editing screen of Movie Edit Pro Plus 2022 but the resultant export is naff (apologies, has "horrible aliasing") or is it naff when played in the editing screen before encoding?

If it plays OK in the editing screen, have you tried exporting as a WMV, AV or even Magix' own MXV video, all using the default settings? This may give someone an idea.

AndyW

Edit - hmm, in England naff is a typically colloquial British word meaning anything from unfashionable (look at those naff jeans) through poor quality (as in the video discussed here) to telling someone to go away (naff off). It's a wonderful word.

I've just Googled it to see what the World thinks naff means and I'd like to apologise unreservedly to anyone I may have offended 🤗

johnebaker wrote on 6/11/2023, 6:50 AM

@me_again, @Emptyflight

Hi Andy

. . . . or even Magix' own MXV video . . . .

This, unfortunately, is a not an option for playback in an external player - it is a custom Magix format and will only play in Magix programs.

Hmm, yes; apologies. Maybe I didn't make the point clear enough when I mentioned MXV. All I meant was try exporting the file in various formats to see if they play OK and I should have added something about the MXV being reimported into MEP to play it.

AndyW

Phew, I think I got away with that one 🙂

CubeAce wrote on 6/11/2023, 7:46 AM

Hi Ron.

I noticed that so far no-one has asked you about the settings you have within Movie Edit Pro?

Could you post some screen shots of the program settings please?

Also you initially said.

I just tried to compile a video using raw material from my 4k Xiaomi phone. Magix movie editor shreds the video and there is horrible aliasing. Never had this problem before.

By that do you mean you have never used a file like that (same resolution and settings) from your phone before or that you have and not had problems with those files before?

Ray.

Emptyflight wrote on 6/11/2023, 7:55 AM

Okay, I converted the file using HandBrake, this time taking care to use H.264, constant framerate etc. It worked fine. And yes, with the original mp4 file and the first HandBrake attempt (using H.265) the clip was "naff" (I did know what naff means, having had enough contact with friends and colleagues from GB) or even "ubernaff" (did I just invent a new term?) in both the Magix editing screen and in the rendered film, although it played just fine in both MPC HC and the standard Windows Media Player. Sorry, run-on sentence. I've never rendered anything as an MXV.

Emptyflight wrote on 6/11/2023, 8:12 AM

Thanks Ray. I meant that I never had problems with those files before. I've used short clips taken with my phone often enough, but only recently had these aliasing issues when trying to edit them. My experience as a layman in all things computer tells me that things usually go wrong after an update - in this case my guess is that in Xiaomi's last update I was given new features I neither asked for nor wanted and the video software was made incompatible. As I said, just a guess by someone who knows nothing. I'm definitely open to any other ideas. And maybe an answer to why Magix asks me if I want to adjust my video's resolution from 3840x2160 29.97 fps to 3840x2160 29.97 fps. Screenshot here: https://drive.google.com/file/d/1N8DfkePz4bKUJV0RNDkfY79l-3iKnUO7/view?usp=drive_link

me_again wrote on 6/11/2023, 8:23 AM

@Emptyflight

That link isn't for the screenshot, it's for the 10 second aliased clip.

That aside, it asks because it's Magix. I get that asked many times with different clips over the years even though I KNOW that it's the same, or rather should be. I usually click on cancel.
