VPX problem with Rotation/horizon levelling

RogerGunkel wrote on 12/4/2018, 4:00 AM

I am still running VPX 16.0.1.255 as it has been totally reliable and I have a lot of urgent projects that I have been working on for months and didn't want to run into some other update problem.

My work is mainly weddings using up to four cameras and inevitably there is sometimes horizon levelling required. This has always been quick and efficient in VPX, but over the last few weddings, both my wife and I have noticed a blurring or softening of the image on even slight amounts of levelling. At first we thought that this was a pre-rendering effect on the monitor resolution, but after rendering there is a clear blurring of the final video clip, as though it is slightly out of focus.

This is very worrying as we are shooting in 4k and the final output at HD quality should not be showing a softening, so is clearly a software problem that we haven't seen before.

 

The loss of pixels on levelling due to the cropping should not be noticeable, particularly as we frequently do some quite brutal pans, zooms and cropping from the 4k footage, without the blurring seen in rotation. Has anybody else seen this or is able to offer any explanation why it has started happening?

This problem is at the developing department - but in the moment you have to do it "by hand" 

Go up to the rotation button and make there a good  horizon. And than you have to zoom it :-))

And excuse my limited english...

Sorry, I should have added this to the list that I still have to put back up. I saw this problem on the French forum.

Thanks Walter and John for the replies. Is this a problem that has been around for a while as I've only recently noticed it? I haven't updated VPX as I wanted it to remain stable at the moment, but wondered if there is any connection with Win 10 updates.

Roger

browj2 wrote on 12/5/2018, 7:47 AM

Hi Roger,

The user on the French forum reported on Nov. 27 that Magix had indicated that the levelling problem was known to them, had been around for a short time, and that they were working on a fix. This was for MEP. It seems that the same problem is in VPX. As Walter said, the workaround is to use rotation and not the Straighten Horizon slider or buttons. As then zoom in as required.

I have added this to the list.

Thanks John,

That does seem to work, which is great as it was becoming a problem where one camera on 45 minutes of a wedding ceremony was not quite level.

Roger

wabu wrote on 12/5/2018, 12:05 PM

Do this: take the whole(!) Clip - use than rotation + zoom und than cut it.

or:

Do this with one cutted clip: make a copy of the effects - than mark all the clips of that camera and past the the effects

good luck

Hi Walter

Thanks for the info.

Just an edit to maybe help with the translation:-

Do this: take the whole(!) Clip - then use rotation + zoom and then cut it (into scenes).

or:

Do this with the first clip: then make a copy of the effects( - minus key) then mark (select) all the clips of that camera in the timeline and paste the effects (shift+minus key).

@RogerGunkel I had noticed this blurring but only thought it was caused by the dynamic resolution reduction that VPX applies during preview. Closer scrutiny shows there is some blurring in the export although I am not convinced that using the method Walter mentioned eliminates it completely. Be interesting to see what a patch can do.

Edit: By the way, I am still on VPX9 .211!

Thanks Peter and Walter.

I tried the rotation and zoom on a couple of clips earlier and seemed to be much clearer than the same clips with the rotation slider. Been out all evening with a client, so no chance to try more, but both my wife and I are editing tomorrow, so we'll see what we find.

Roger

RogerGunkel wrote on 12/5/2018, 6:48 PM

@Scenestealer Just a follow up to say that the dynamic resolution reduction shouldn't give a noticeable blurring on 4k footage in a 4k project, and certainly not something I had seen until recently.

Roger

Scenestealer wrote on 12/5/2018, 8:53 PM

Not on the exported footage, especially to HD, but it does during preview as it drops the resolution to the monitor window if "Reduce resolution" is checked and is active in the Program settings or the Lightning Bolt button. With a processor hungry effect it chooses "who knows how low a res." to enable smooth playback and the change will be more noticeable with a 4K project.

This has been visible for many versions of VPX and MEP on my machine.

RogerGunkel wrote on 12/6/2018, 6:00 AM

The worry for me is that it is very noticeable in the exported footage to HD mp4, but I will try the suggested work around again on some short clips and see what I can find.

Roger

RogerGunkel wrote on 12/6/2018, 7:52 AM

Here is some discarded footage from a wedding I am editing, where I accidentally left the video running while I was taking some stills. All three clips are from the UHD timeline converted to HD mp4. 01 is the basic footage, 02 is using the normal slider rotation bar and 03 is using the suggested rotation dial rather than the slider, then zooming in to remove the black borders from the rotation.

The problem with the slider rotation is glaringly obvious on 02

Roger

gmlotkow wrote on 12/14/2018, 1:44 PM

I just realized I had the same problem, rotate and zoom is much better

EDIT

But, it does OK for what I do, seems the extract audio tracks (5.1) performs quicker.

Wish I had more DVD templates.

Hi Roger.
I have only ever used the top rotation arrow then crop as needed.
I do a lot of leveling with all my footage and this system has always worked fine even with version 304.
Doug

RogerGunkel wrote on 12/17/2018, 6:45 AM

Hi Doug,

I agree that top rotation arrow and crop works without any problem, but the beauty of the levelling slider has always been it it so much quicker to use as the cropping was automatic. It has always worked fine until recently, so appears to be yet another bug that is creeping in with updates, alongside a lot of others that have been mentioned. Someone else said that Magix seems to be trying to add new facilities to the programmes, without making sure that the base software is bug free, which it should be after the the years that it has been 'improved'.

It has reached the point now where I am reluctant to upgrade incase some new problem shows that interferes with my ability to work quickly and reliably to maintain my business. I have used various versions of MEP and VPX for many years and love the flexibility of the software, but the constant bugs that seem to appear with each new upgrade and the degradation of what previously worked flawlessly, has made me very nervous.

I am even considering looking at alternative software when my workload reduces by the early Spring even though I realise the headaches that will cause me.

Roger

@RogerGunkel
Welcome to my life Roger.
The strange thing is, when I have contacted support about issues, it's the first they have heard of it yet they are all issues that have been covered in the forum.
My free upgrade period ends in March so I don't know if I will bother extending it until the basic problems are addressed.
Everything is working fine for me at the moment with rare crashes and DVD Architect is doing what I need for the DVD part of things infact it blows VPX DVD encoding away.
If the release notes don't address any of the bugs I have then it's probably not worth updating.
I think we can give Magix a list of bugs forever but the fact is, there will always be users with problems because we all use it differently.

Hi Doug,

I agree that we all use it differently, but what makes me nervous is that there are new bugs coming in which just do not seem to be addressed, even though new features get added from time to time. Some of the new bugs that weren't there before such as the rotation bar problem, not being able to change the colour of individual words in a title, titling shadow and 3d effects being hit and miss, plus various other small bugs that I can't think of until I find them again while editing. these are things that should not appear after a new upgrade. There should be a stable platform the new features are added to, not and upgrade that degrades previously stable features.

It is now affecting the way I work and taking more time to remember a new work around or finding an alternative because I can no longer do something that was previously taken for granted. Because of some of the new bugs that have been mentioned on the forum, I have not upgraded for probably the last 3 upgrades, and may well not bother to continue with the programme after my current crop of projects are edited.

Hi Roger

. . . . Some of the new bugs that weren't there before such as . . . .

. . . . not being able to change the colour of individual words in a title . . . .

AFAICS there has been no bug introduced, as you can see below (VPX 16.0.2.304)

The trick is to select the text in the Preview monitor, note the required mouse clicks can be dodgy, as you can see in the video.

. . . . titling shadow and 3d effects being hit and miss . . .

Agreed, however I have found the Border, Drop Shadow and 3D effects depends greatly on the font style used.

Border, Drop Shadow and 3D are global effects which cannot be applied to individual letters or words.

Thanks for the video John, however you aren't showing me anything that I haven't tried many times before and finally given up on. I've made my own short video to show you the problem which only affects colour change (sorry I forgot to move the capture screen). If you can direct me to a solution I would be delighted 😃

Thanks,

@RogerGunkel

Hi Roger

After watching your video, the obvious difference I can see is you have the Drop Shadow turned on - I suspect this is forcing you into global mode, as would Border and 3D when on.

Try turning off the Drop Shadow, (mine is off by default), make the changes, then add Drop shadow if needed.

Hi Roger,

I can't replicate your problem. In your video, I noticed that, after highlighting some text, as soon as you click on the colour button, the highlight of the text is lost. This happens to me if I click somewhere else, like on the vertical scroll bar. I don't see this happening in your video, so I don't know what could be causing your problem. I'm on patch 304 and I think that you are on 255, correct?

Other topic, I received an update from Magix about the list and I'll post it in the thread about 304.
