Hi,
I downloaded few clips from Twitch streams and when I import them into Magix Movie Editor, audio works and few first seconds of video shows, but then video goes blank. This happens with all clips and different Movie Editor versions. ATM I am using Movie Studio 2023 Suite.
It seems that this problem is only with Twitch created clips and not Twitch created Hilights. Hilights seems to work fine.
Do you have a link to a Twitch we could check out?
If these are game pay video clips from twitch then the chances are they are variable frame rate files with large sudden frame rate changes between fast action and static sections.
Ray.

So there are nothing that can be done? I tried program that re-writes those files and it worked, but that is an another step to the process.
Hi
. . . . Twitch created clips and not Twitch created Hilights . . . .
Download and install MediaInfo and analyse one of each type of clips causing the issue, see this tutorial on how to setup MediaInfo and analyse a video clip for all the data required.
In the video section of the analysis if you see this line:
Framerate mode: Variable
Then the video needs converting to Constant frame rate with a video converter such as Handbrake, or AVIDemux.
If the video is not variable frame rate then post the 2 analyses in a comment for us to look at at.

I have two exports from Twitch. I was wrong when I said that clips does not work but highlights does. It seems that only unaltered stream VOD works
First clip works fine (unaltered VOD), second shows few second video and then goes black (higlighted VOD)

The second clip should actually run and work.
The first clip wouldn't work for me. Are you sure you didn't reverse the order?

Magix hardly ever gets by with these values.
Hi.
@Marc-Goder is correct. you seem to have posted the information in the wrong order and yes you would have to convert such files to a constant frame rate and preferably all files within a project should use the same frame rate.
Ray
My order was correct. First file (Scum uudella serverillä.mp4) worked and I edidted and exported it. The second one (scum2.mp4) didn't work more than few seconds.
Anyhow, so it seem that I do have to convert. Any suggestions for AVIDemux convert settings?
Still a WIP but you'll get the ghist of it...
Using Mediainfo, determine desired frame rate
Video Output>Filters
Transform, DC on Resample FPS
Mode:Custom
New Frame Rate – as per Mediainfo
Interpolation ??
OK, Close
Output format MP4 Muxer
Save As
I forgot to answer this. Yes. Transforming seems to work. It will take long time, but atleast Movie Editor now shows video and plays audio. I just have to make shorter hilights. Editing i.e. 5 hour stream from one file is tedous job.
Thanks for the help.
