Hello dear people,
I know someone who produces a lot of videos for Youtube. He uploads at least one video per week. For this he uses the video editing program 'Magix'.
This program works great for him. He bought the license 'Video Deluxe Premium'. He got this cheaper in a sale.
He has the following PC specs:
AMD Ryzen 7 1800X, GTX 1070 Dual OC (8GB), Asus ROG Crosshair VI Extreme, Intel 660p M.2 NVME SSD, RAM 16GB 2666Mhz Crucial Ballistix Sport
He always has too little CPU and GPU utilization (see the reference video for details) and it takes far too long to render the videos. In my following evaluation, I have a standard video with different encoders and settings repeatedly rendered (for details, see evaluation).
The following Magix settings are available:
Encoder: purchased license 'Main Concept' encoder and standard encoder
Audio in wave form in video
Video standard 'PAL' encode without hardware acceleration: AMD CPUs do not have their own graphics unit (iGPU like Intel) and therefore can not be used for hardware acceleration (see any other forum entries). This is a well-founded statement, since it is already confirmed that with all video editing programs on AMD CPU's no hardware acceleration is possible. This phenomenon, which is not solved yet and maybe someday hopefully it will! This could speed up the rendering process (encoding, decoding) many times over!
I have not been able to upload more pictures, but many others have the problem ...
Test video (reference):
MP4 format, full HD 1920x1080, 59.94 fps, video bit rate: 100,000 kbps, audio bit rate: 320 kbps in stereo -> comes from Dashcam 'iTracker' Test conditions:
2 Chrome tabs open, nothing else open to produce unnecessary load, CPU usage: about 1% without rendering.
Picture 1: Test parameters and references
Figure 2: Test parameters and evaluation of the finished video
So these were my attitudes for him. Read it through well, otherwise you hardly check the diagrams.
Picture 3: Render times
Here you can see that with the Windows Media Video Export the render time is much smaller (in comparison to the standard MPEG-4 export - first two columns). The standard encoder takes far too long. Although the Magix video export takes a little shorter but you can see in the evaluation in Figure 2 that the video quality is not enough for him.
-> Windows Media Video Export
Figure 4: File sizes of the test videos.
Here you can see the much smaller video size of the WMV (Windows Media Video) export. This is especially important for his recourses (TBW an SSD is already high but still comes together a lot over the years). He always deletes the finished videos after the upload... :/
The WMV export is therefore well suited for an infinite data storage of its videos for a server / NAS.
-> WMV export
Fig. 5: CPU utilization (only for Magix video, not for complete system), read in Task Manager
Here you can see that the WMV export has significantly higher, but fluctuating values for the CPU utilization. The CPU usage is a bit better for the reference, so you can prepare the next project next time. Who can explain the higher utilization here? That depends definitely with the encoding of the WMV's together?
-> WMV export
Figure 6: GPU utilization, always for maximum value (read in Task Manager)
Here you can see that the GPU utilization for WMV export is slightly lower than for the MPEG-4 export.
-> WMV export
The wmv files can also be uploaded with Youtube, so everything is fine!
You may wonder why the spaces for the 10-minute reference video are empty, unfortunately I have not been able to create them yet. It's all about testing UP scaling. Are the render times / file sizes directly proportional to the 1-minute video? He usually produces 10-15 minute videos....
Conclusion / Discussion: An optimal setting for shorter rendering times / smaller file sizes offers the following setting: MP4 Videos - MainConcept Encoder (Magix) - Windows Media Video 9 Export (Magix) - Decoder Complexity: Level 2 (live) (Magix)
Under these settings comes out a perfectly acceptable video that is in no way inferior to the original in image quality and sound quality! He looked at the videos and said that it was like his last videos.
I have learned a lot and can pass on much. So if anyone has problems, then read this post and share it with others!
I am glad that I was able to help him and that he can produce videos faster by 1/3 !!! And believe me, that makes for precious life in a year! It is worth it!
Thank you for reading,
Your Tobi :)

I'm sorry, the images are in german, but you can understand the graphics if you look to the encoder.
