MEP 2020 TK2 Bug

Am I the only user actually inconvenienced by this bug? On reporting it to Magix I received the following response:

"Thank you for your message and this hint. Actually this problem has already been reported so I have already created a bug entry for this. I will address this problem in our next meeting and hopefully we can provide a solution very soon.
We hope for your patience."

"Next meeting"? "Hopefully"?

I confess that in my innocence I expected this bug to be fixed in a couple of days. After all, we're not talking about some transition that doesn't work, or an obscure effect that freezes the screen: this bug affects the very functionality of the program, to the extent I've been able to do nothing with it for almost three weeks because my "work"flow depends on "takes". If I was doing anything useful with the program I'd be spitting tin-tacks, but fortunately I just mess about with Super 8 family stuff so I really can't huff and puff too much.

I assume that no-one else can be using TK2s or there'd surely be more of an outcry over this issue. In the absence of a bug fix from Magix I've given up hope and reverted to MEP 2019. A pity - I did rather like the look of the surfing lady on the startup screen of MEP 2020.

Hi Peter,

As I mentioned, in the case of the S8 film, progressive, the interpolation in my test cases were actually an improvement over frame duplication. It's just that stabilization does not get along very with it.

Vegas Stab - negative Extra Zoom doesn't work, goes back to 0.

Hi John

Just to clarify your terminology - you mean:-

1. Interplolation = Adjusting in the Object properties

2a. Frame Duplication = Selecting Interpolate Frames in the Speed dialog which creates intermediate frames?

or,

2b.Frame Duplication = Adjusting the speed? eg 20fps to 18fps which adds or subtracts frames.

Further to this: - Does your analysis of any of these give you an impression of what the extra frames in any of the above look like per frame? IOW do any of them look like truly synthesised frames that are different spatially from the adjacent frames as would happen when using Motion. I would guess not because if they were they would need quite a bit of processing in a long clip to display them as in a slow motion program like Twixtor, and in MEP the change seems instantaneous.

Hi Peter

Assuming you are referring to my post above then

To clarify -

Interpolation means calculating new frames in between the originals when slowing down the video as shown below.

1 and 2a - whether you select this in the Speed effect option or the Object properties the corresponding check box is set in the other option, ie they are the same.

2b - AFAICS there is frame duplication/dropping only when the project framerate is faster/slower than the source video and no Interpolation is set and then only when exported - the Preview appears to use the video clip original framerate.

I would assume the Object option is for when the project and source video framerates are different, however you are not making any speed changes.

Hi Peter,

Assuming that you were referring to my post, we were still talking about the S8 film, digitized at 20fps, modified to 18fps in a 25 or, in my case, 29.97fps (or 30fps) project. MEP/VPX duplicates frames to get 25 or 30 fps from the 18fps.

Below are frames 2 and 4 from an untouched S8 video; Speed changed from 20 to 18fps, project 29.97 fps. The first 2 are original frames 2 and 4. They are duplicates of frames 1 and 3.

The following 2 are the same frames 2 and 4 but with interpolation turned on under Speed:

You can clearly see the difference between before and after. The interpolated frames look to be part way between the adjacent original frames, that is 1 and 3, 2 and 4.
