Hi, welcome to the Magix forums.

Thank you for providing the specs of your computer. However, we also need to know exactly which version of MEP Plus you have (please check under Help>About) and the detailed format of your video files.

Have you tried using the blue lightning symbol below the video screen, which allows for reduced playback resolution etc? This will only affect the files whilst you are editing; the final export will always use the full resolution files.

Have you tried the option to create proxy (lower resolution) files for playback and editing? Again, this will not affect the final export.

However, I think your CPU may not be fast enough to handle the necessary throughput of data for video editing. A very quick Google search led to this page which seems to suggest it is one of the slowest etc. in its class.

Thank you for your reply.
My version of MEP is Version 17.0.2.159 (UDP3) and the one video that I'm trying to use is AVI file. It is a 2:40 long video, filmed at a resolution of 1176x664, with an audio bitrate of 192 kbps.

I do have it set on reduced playback resolution and frame rate.

It is set to create proxy files automatically.

I don't think my CPU is the main problem. The 2015 version ran much better then this version, (I could preview HD footage fairly smoothly) and this version claims to run much faster, which was part of the reason why I got it in the first place.

Hi. Thanks for the additional information.

Can you find, download and install the free MediaInfo utility? Point it to your .avi file and then post the results of the Text view here. That will tell us an awful lot more about the actual file. .avi is a container format and that, along with the rather unusual format of your footage, may be contributing to the problem. What is the source of this .avi file? Is it a sportscam, something like a GoPro or similar? I ask that because I know other users have experienced problems playing such files and have had to resort to "adjusting" in some way the output files before they could be used/edited in MEP.

Uncheck "Overload optimization for realtime playback" in settings>program>playback maybe that can help, if not I would use the Radeon integrated graphics

Very interesting string. I am having real problems with handling gopro 6 video where as my old hero 4 worked perfectly in all the formats i.e. 4K and 1080p. I am using the latest version of Magix Edit Pro Premium.

@gezzat12

Please start a new topic with your GoPro issue, this one is about screen recording - hijacking a thread is not good forum etiquette.

Thanks

@emmrecs Does the info I gave you help at all? If I can't get this to work properly, I might need to ask for a refund.

@Spad

My apologies for the lack of any reply.

I must confess I'm stumped! I can see nothing in the MediaInfo data that would suggest a reason for the choppy playback, assuming you have set MEP to the 60fps speed? Other than that very unusual aspect ratio, 1176 x 664, everything else appears quite "normal"! (I don't think the mp2 audio format ought to be a problem, but I'm not sure.)

Can you post a very short extract of the file to Dropbox or similar file-sharing site and add the link to your next post, to allow other users to test it on their machines? Don't attach it to any reply here since the forum software will compress it and thus not give anyone who wants to test it the opportunity to do so on an unchanged file. I would certainly be interested to test it on my machine.

Here is a Google Doc link to the entire video that I'm trying to use. I hope this can help! Let me know if I did something wrong!

At close to 1 Gb that’s hardly the “very small extract” that Jeff requested! Nevertheless I’m prepared to try it, but ... it seems to imply that your issue is confined to this one file?

I interpreted your original problem statement as a general one, about this version of MEP. You compared current performance as inferior to that you had with MEP 2015. Do you mean generally, or just with this 900 MB file? If the former, do you really have no much smaller examples?

Okay, so I did a little more testing, and it seems to act differently depending on the video.
I recorded two more videos the same way as the original, but with two different games. One works perfectly, while the other stutters really badly. I uploaded both to Google Docs so you guys could see.

The one that works fine. (Much smaller game.)

The one that stutters. (Similar if not same quality as original.)

https://drive.google.com/open?id=1hyl56rYNvOANCOgMddIrMwaHIAav3iPm

Both are recorded at 60 FPS, at the same quality, with Bandicam. (I do have proxy files turned on.)

Hi again.

Thanks for the files, although I've so far only downloaded the first and tested it.

For that first one, I opened your file in MEP Premium 17.0.2.159 and MEP asked whether it should adjust the movie settings to match the somewhat unusual aspect ratio of your file and I chose "Adjust". On pressing Play I immediately saw the same thing as you, very choppy playback. I then noticed that MEP had defaulted to playing your file at reduced resolution and frame rate (the blue lightning symbol below the playback screen was highlighted); just out of interest I turned this off and your file played without a hitch!

However, one thing bothers me. I see that your file includes the audio track but that does not seem to import to MEP; your file is silent with no audio track showing. I need to investigate this further but, for now at least, you should be able to play your file without a hitch. (If you want to see the spec of my computer, click on my signature.)

@Spad

There are significant differences in video in the 2 files you have uploaded - AVI is a container file and can have many different codecs internally.

Good file - 552 x 836 60 fps h.263 XViD

Bad file - 1768 x 992 60 fps h.264 AVC

. . . . I could preview HD footage fairly smoothly . . . .

What video format and resolution are/were these? HD is generally regarded as 1280 x 720 resolution, the 'bad file' is closer to Full HD 1920 x 1080 - a 'subtle' difference however an important one as is the difference between h.263 and h.264 codecs.

The 'Bad file' is approx 4x the pixel count per frame compared to the good file and requires significantly more computer power to playback than the 'good file'.

IMHO the PC is not powerful enough; with 8GB of RAM and running Windows 10 on a low performance processor it may have just been tipped over the edge handling AVC high resolution video in MEP.

I tried turning of those options, and while it did result in slightly better performance, it still stutters badly. And the audio seems to work fine for me. That's the one thing that DOES seem to work perfectly.

Okay, that makes sense why that one wouldn't play properly, (tbh I forgot that the game was running in that res) but that still doesn't explain why the original 1176x664 video doesn't run properly. I do want to point out that working with the same quality video of the same game on the same settings on MEP 2015 works fine.

It's quite confusing that the higher res video runs better then the lower res one. The higher res one just stutters really badly, while the lower res one just freezes and will occasionally display a few frames. And the audio is fine on both.
