Hi

MMS 2023 does support 4K editing, however, in addition to, as @CubeAce has commented, the codec requirement for importing there is a 'gotcha' with the graphics card/chipset in your computer.

The HD 630 integrated GPU does not support 4K hardware acceleration, the GTX 1050 does support hardware acceleration, however it is important that the graphics card are up to date, the current version for the GTX is 546.17 (31.0.15.4617)

Correction - the Intel HD 630 driver latest is 31.0.101.2125

Also check in the Program settings, Device options tab that the Import, Processing and Export options are set to the GTX 1050.

With 4K video and your computer spec, proxy files are a must for smoother playback of the timeline. You may experience a poorer playback with some effects. If so you may need to test the other options for the Processing option previously mentioned.

Thanks for responding. Not sure if I was describing correctly I know you can import a 4k file and adjust to 1080 but cannot find any setting when creating a new project to select 4k 3840x2160 as the project settings. Sorry if I am missing something.

@derek-brown

Hi,

The options are right on the startup screen.

@derek-brown

…and in the program under Movie Settings shortcut E.

John CB

Hi Thanks. I do not seem to have that option in my movie settings. I am using v 22.0.3.152

@derek-brown

Arr, yes, the old "4K" red herring. From the first video Settings droplist, choose UHD/UHD2. Then, on the next droplist down, choose Ultra HD TV. That will give you 3840x2160.

"4K" is actually something quite different: 4096x2160.

For 16:9, people should be saying "UHD" but it is cooler to say "4K". 😉

I thought UHD/UHD2 was 8k ?

@derek-brown

UHD is 3840x2160. Going on the droplist in Movie Settings, UHD 2 is 8k.

A lot of the menus haven't been translated well. Example with the latest version: "Export to MPEG 4, HEVC, AVI". They are all MPEG 4.

Thanks for your help. Shame Magix do not mention it anywhere.😟.

@derek-brown

This screenshot is MMS 2024 (which I think should be the same as 2022 for the Movie Settings).

@derek-brown

Looking at 4k vs UHD, from what I can see, if UHD is exported as 4k, the picture is squashed horizontally in VLC Player and Virtual Dub. The image, when set to the height that shows no top/bottom bars, shows the sides well padded with bars, meaning the image is squashed horizontally. While the window itself looks like 17:9 (1.8888), the video doesn't fill it when it should. That might be a Magix coding issue.

On my TV, the side bars are ignored and the picture displays correctly at 1.88:1 ie with small black bars top and bottom, except that, as the original was 3840 (UHD), the 4k export will still be distorted.

thanks again for your help. Will play around with but as you have demonstrated looks like will need to film in 4k and adjust to 1080. I believe quality is slightly better than filming in 1080 and editing. I think ?

@derek-brown

Yes, better to downscale IMO. Remember, though, that if you film in 4k (as opposed to UHD), you'll have to crop off the ends to fit into the 16:9 frame. Here's a 4k movie clip (17:9) in a 16:9 frame:

@derek-brown

Hi

. . . . need to film in 4k and adjust to 1080. I believe quality is slightly better than filming in 1080 and editing. . . . .

Personally, I only film in 4K UHD.

As far as the project settings go, it makes no difference if the project is set to 4K UHD or to Full HD (1920 x 1080) if the only export format required is to be Full HD (1920 x 1080).

Whether the quality can be subjective and depends on the many variable factors which are different from person to person, eg cameras used, monitor differences, TV differences etc.

The advantage of filming in 4K UHD and exporting as Full HD is that you have an extra range of zoom available 'in edit' without quality loss.

There are 2 main disadvantages with filming in 4K, the computer specification may mean having to use Proxy files, and the extra storage capacity need, especially if archiving the projects and source video.

John,

John, which is it, 4k or UHD? They are different, as I have explained above: 1.88:1 verses 1.78:1. If you try to export an uncropped 4k video on a 16:9 timeline, you end up with black bars top and bottom.

To get around this, just film in UHD (which, I add, my Samsung phone does; it does not have "4k" at all, only UHD and 8k, while the iphone (11), perversely, calls it's video 4k when it is actually UHD!).

Hi John Thanks agin for all the help. Experimenting with settings for 4k and the software wants to turn my video updide down. Loads okay but after copying to timline loads upside down in preview window . Go to effect and rotate back and then render when edited. Use neat video to improve any noise and video turns upside down. Then when I render and play turns upside down. Is there a setting that reverses view?

@AAProds

Hi Al

. . . . which is it, 4k or UHD . . . .

Both together is the standard designation for 3840 x 2160 16:9.

The other resolutions that cause confusion are 1920 x 1080 16:9 - standard designation is FullHD (FHD).

You will see this often and erroneously described as HD which is actually 1280 x 720 16:9.

The naming of resolutions is an absolute 'mess' see here for an example.

John EB

@johnebaker

Both together is the standard designation for 3840 x 2160 16:9.

But with resect to Magix video movie settings, each one is obviously different, as shown by the droplist in Movie Settings, and if you use a 4k ie 4096x2160 video for a 16:9 movie, then you'll have the top and bottom border issue unless you crop. Since TVs are generally 16:9, it's best to shoot UHD, being 3840x2160.

I just re-read the first post by @derek-brown; he's using an iphone 11 Pro. If that makes the same video as an iphone 11, then he's OK because even though the phone says it's 4k (4096x2160), it's actually UHD (3840x2160). He should therefore be using the UltraHDTV or the FullHD video setting.

@derek-brown

Re your flipping issue, I tried it here and it appears Neat Video looks at the original video, not at the flipped version on the timeline. I'm not sure I'd call that a bug, more a "that's how it is". It would be nice if it operated on the flipped image though.

On flipped video generally, it is a pest because some multiple effects don't play nicely with video that has been flipped.

I have had success using AVIDemux to flipping and resaving a video before importing into Magix. Occasionally though, my procedure didn't work. If you have only a couple of problematic videos, you can try my tute to flip them permanently:

@derek-brown @johnebaker @AAProds @browj2

I'm finding myself in agreement with John Baker on this one but with additional conditions as Some cameras that shoot at HD can give cleaner clearer video than other cameras can at 4K, especially when having to shoot at higher ISO values.

Frame rate also comes into the equation for quality when talking about exposure times and the advantage in the resulting ISO value used and amount of wanted motion blur.

For the casual user not much of that matters but quality can be improved by the use of ND filters allowing correct exposure and if the camera allows the amount of sharpening and colour enhancement (or lack of) baked into the final video file before editing begins.

I have been scouring the for iPhone 11 pro 4K video footage to download and all of them (9) so far have been 3840 x 2160 so no problem there. (I think).

I have also looked for a video editing package that can import and export files at a native 4096x2160 and so far have not found one. What do you have to do Al?

For me personally video is like taking still photos. I will choose the settings I feel I need for a given project if it is important. If it is just a day out or I have no plan then I will shoot at UHD (to be pedantic) at whatever frame rate I feel the lighting conditions warrant.

Sometimes I have used a setting and then regretted it such as when trying to slow down footage for effect. Too slow a frame rate can have a bad effect on the slowed down audio that can't be easily corrected.

I feel there is compromise in anything we try to achieve.

It is strange as never happened before, Only the 4k video flips the 1080 plays fine. The 4k does not flip if I import to timeline but flips if I copy to timeline,Forgive me for this question as probably is straight forward. When starting a new project and setting the movie setting to HDTV 1920v1080 and then adding a 4k video to the timeline you are then prompted to adjust,if I press adjust the settings change to 4k and the file size is 105MB. If I do not adjust and the video is then played as 1080 the the file size does not change from 105MB. I thought as you were removing pixels it would decrease the file in size ?

@derek-brown

Hi Derek.

The properties of an imported file do not change as it is the original file and the editor doesn't touch or alter the original file. It has no bearing on the quality of the image you see in the Preview monitor or the size of the finished exported file. The data you are reading is from the original file. The exported 1080 file at that stage will be upscaled to the desired screen resolution.

Ray.
