Andy, rest easy. The last bugfree version of Magix, MEP 2021, does exactly what MMS 2025 does. The play marker itself doesn't move until you stop the play.

@Gid @AAProds

That's a relief, thanks both. I must have seen it before but not noticed if you know what I mean. That's a worry in itself 😟.

Time for another cup of tea.

Hi Andy

That has been the normal behaviour since MEP 2015 and possibly earlier

@johnebaker

Thanks for the info John, I think😱. I've had MEP2015 and 5 versions since then and I've only just noticed? How much are straightjackets these days?

Hi Andy,

Funny, I noticed the same thing in VPX recently and thought that the program was slowing down. Must be the heat.

Greetings,

OK, I've just noticed something else that I've no doubt seen but not looked at - if you know what I mean. It's the little CPU monitor bottom left of the screen.

I assume the % figure is the CPU usage (seems to vary between off and 9% depending on what effect is being used) but I can't decide what the figure in brackets next to it means.

There are 2 figures (X/Y) where X keeps changing on playback and Y stays constant. In my case, during playback, the figures change up and down fairly quickly between 1/35 and 35/35 again depending on what effect is in use.

I thought at first this relates to CPU cores being used but I think my CPU only has 20 cores. I can't find anything related to video processing with 35 things to be on or off.

I've looked in the manual but it would appear that it doesn't exist anywhere so it's obviously not important enough to even mention.

I don't think I've missed it during the 2 (ish) decades of Magix use but now I've properly noticed it I'd be interested in knowing it's purpose other than confusing an elderly person with not a lot better to do - so MrsW tells me.

AndyW

Looked at it once years ago, saw it was showing nonsense, never looked at it again! 😁

@me_again

Hi Andy,

My copy of MMS2024 only has the CPU % usage but no 35/35. In VPX16 it has CPU % usage and 35/35. I wonder if there is a setting that can be turned on/off or is this a feature just available on VPX?

The 35/35 is pretty consistent. When I start playback it maybe starts off at 20/35 then immediately goes to 35/35 and tends to fluctuate around 34/35 and 35/35 sometimes it will drop to 1/35 and this seems to be at consistently at certain parts of the video clip. It appears to be some type of indicator on how well/smoothly the video is playing but I'm only guessing.

Correction; I reset my program settings in MMS2024 and now the 35/35 is appearing.

@AAProds @Can-Dive

Thanks, I'm glad it's not just me. It's a good point about indicating how smoothly the video is playing but I would think that's easy enough to tell by looking at the preview window and why 35 units of whatever it is? I suppose It may have had some use in the dim dark distant past when computers were steam powered(?).

I'm with you on this Al "saw it was showing nonsense, never looked at it again".

AndyW

@Can-Dive @Gid @johnebaker @browj2 @me_again @AAProds

I'm fairly certain the 35/35 is showing how many frames per second is being played in the preview monitor. Possibly effected by how much processing the CPU has to do when rendering certain applied effects in real time that rely on the effect using the CPU rather than a GPU. The second 35 meaning the maximum shown frame rate possible.

@CubeAce, @Can-Dive, @browj2, @Gid, @me_again,

Hi everyone

. . . . The second 35 meaning the maximum shown frame rate possible. . . .

This is correct, however it appears to be for the GPU, when I switch the 3 device options to CPU I only see the CPU %.

John EB

@CubeAce

Greetings Ray,

Frames per second? A possibility but why 35? I noticed it on a pal video @ 25fps. It makes no difference what the fps of the clip is or what the project is set to. @Can-Dive also has 35 so I can only guess that that is what MS/VPX is set to for whatever reason.

I suppose it could be just a scale which I assume is what you meant with "The second 35 meaning the maximum shown frame rate possible". It just seems an odd number - both arbitrarily and literally 😇.

I think you may have it though, not necessarily frames per second but a scale of CPU use - I've not written that properly but I can't think of a better way. I'll explain:-

Clip with NO effects - CPU 0% 35/35 smooth

Clip with CMOS Fixr, Mercalli, NeatVideo, Video Tuneup Plus (NewBlue) - CPU 3% 14/35 stutter every 2 seconds

I wish I hadn't looked at it now as it doesn't really help me, although I can possibly see how it may help someone with a low end system.

@me_again

Hi Andy.

Magix makes a big thing about how smooth playback is on not very powerful computers. 35 fps in most instances is above the 24fps needed for human visual coherence for the majority of people and sits reasonably well within most monitor refresh rates / pixel response times if you are not using a gaming monitor. So it seems to me that reducing the playback frame rate would be one way of achieving that smoother looking playback.

Other things that seem to effect how smoothly the playback is apart from the codec in use on my system is what size you make the preview monitor. Not how large you make the view but seems more like a percentage scale of the amount of screen space it consumes. Larger monitor viewing can run as just as well as smaller but sometimes sizes between the two makes the program stutter the playback more. At least that is what I experience.

Even my audio DAW has a similar CPU meter tucked away in a corner but that shows how much CPU the program is using compared to the amount taken up by anything that may also be running in the background of Windows.

Maybe it is there for the developers but left in program.

Ray.

@johnebaker

Hi John.

Just noticed your post. You are correct. I never noticed before. That would be useful for testing various GPU performances.

If anyone wants to try out the Hitfilm effect Damage, if they have it, it rocks but the lag on my system when trying to alter a slider is unbelievable.

Ray.

@johnebaker

Just seen your post John. I'd started the post then got called away by MrsW for a serious cup of tea and it must have come in during that break.

That explains what it is but 35 still seems a very odd figure.

AndyW

@me_again

Hi Any.

From what little research I've been able to do it is the sweet spot in both nvidia game play and AMD graphics drivers for efficiency. Efficiency in what exactly I have not been able to find out.

@me_again, @CubeAce

Hi Andy

. . . . That explains what it is but 35 still seems a very odd figure. . . . . Efficiency in what exactly I have not been able to find out . . . .

As Ray has commented this is an optimal setting, 'sweet spot', my assumption is that this is in relation to the buffer sizes, and the average amount of GPU RAM on graphics cards, and allocated RAM for integrated GPU's.

John EB

@me_again

Sorry I misspelled your name last reply Andy.

I think @johnebaker has hit the nail on the head and may also explain why so many video editing programs at present all have the same basic hardware requirements that have similar project handling capabilities.

Ray.

@CubeAce, @Can-Dive, @browj2, @Gid, @me_again,

Hi everyone

John EB

That makes sense as to why I did not initially see the 35/35 ratio in MS2024. I probably had the device options set to CPU. When I reset the program setting, the device options would have defaulted back to the graphics card and it reappeared. To take @johnebaker observation a step further, I discovered that it is only when "processing" is set to CPU does the 35/35 ratio disappear so it's definitely related to the performance of the GPU and its ability to handle effects and playback; see below;

Why the 35/35 ratio instead of a percentage like the CPU %? I'm only speculating but if you have two percentage numbers displayed one may forget or confused as to which is related to the CPU versus the GPU. Displaying a ratio beside a % is much more distinct.

Why 35? I do believe it is related to frame rate. The Development team is located in Germany which is a PAL region. The common frame rates are 25 and 50 which are multiples of 5. So the timeline could have video clips with either of these frame rates. The average of these two is 37.5 which is a bit of an odd number. So the team thought let's either average down 2.5 frames to 35 or average up 2.5 to 40. At the time the decision was made 25 fps was more common than 50 so they decided to round down to 35. I'm only guessing but this may have been the thought process in coming up with the number 35.

But then again, rather than guess, we could always ask the development team. 🙂

@CubeAce @AAProds @Can-Dive @johnebaker @browj2 @me_again

I only ever glance at that box when the timeline playback lags for some reason, the numbers change a little but it doesn't really tell me much, all it's showing is that my CPU/GPU is doing some work ... like it should be doing 🤷‍♂️

Why 35? , Because 34 isn't enough & 36 would be silly 👍

@Gid, @CubeAce, @me_again, @Can-Dive, @browj2

Hi everyone

. . . . the numbers change a little . . . .

Same here at the initial start of playback they drop to the low 20's for about a second, after that constant 35/35 with the effects I have tried, eg PIP, Blur, colour adjustments - working from my laptop at the moment..

. . . . Because 34 isn't enough & 36 would be silly . . . .

👍👍👍 and 42 would be too obvious!

John EB

... and 42 would be too obvious!

Ooh I don't know John. A lot of Deep Thought has already gone into this topic 😊
