That's the way VEGAS is. VEGAS' strength is editing efficiency, not preview/playback fluency.

And you can do the vs between VEGAS Pro 18.0 and Premiere Pro cc 2020. You will find that the diffierence will be more big.

Maybe this is because they use different programming languages/platforms. C++/QT's performance is better than C#/.NET.

The core of vegas is a decade old. Other video editors require A CPU with optimised instruction sets like SSE4, avx, avx2, as far as I know vegas pro 18 doesn't.

Magix VPX actually says it's for this reason it's so much faster

AVX-optimized algorithms Video Pro X's AVX optimizations for internal image processing and 3-way color correction make image processing much faster, deliver much more precise output quality on color conversions and free up resources for the use of additional effects.

I'm was so excited to try out V18 but I feel very disappointed .... The setup is nice but impossible to work effectively on it because of slowingless .... For me the playback must be fluent.... I guess we have to wait and see if version 18.5 or 19 vill be written in new code. .. But I honestly don't believe it will...having VPX speed in V18 would be a "killer" editing software. ..... Thanks for the feedback guys 👍

Interesting as I am not experiencing the lag you are (4K timeline with Best full in preview). Are your source files on an SSD? My PC i5 3rd gen at 4GHz, 1080Ti GPU and 32MB ram.

Yes, they are on Intel SSD...

AMD Ryzen 7 3700 8=Core 3.59GHz, 16 gb Ram .......maybe the ram is the got 32gb but I have 16gb

Note that Vegas will only ever use 50% max of your installed RAM.

I apologize @andyrpsmith ..... you were right ..... I had these source files on an external SSD ..... I did not realize it until I checked just now the documents I was using yesterday, embarrassing.

I have tested 4k file from the main drive and it works fine, tested external SSD and external HDD and to my great surprise the external HDD works well but not the external SSD.

Ram went up to 2.2gb the most when I was doing these tests ..... but cpu went up to 70-75% use....

I'm going to test V18 a little more before I complain more😂

but VPX and MEP play these files from all these 3 drives without lag.......which is interesting

I believe best performance is from Vegas on ssd c: and source files on internal ssd other than C:

Have you tried copying large files from SSD to internal SSD, is it USB3 fast, much faster than the external HDD or something wrong with it?


Brynjar-Gudmundsson wrote on 9/16/2020, 2:43 PM

This is a very strange case. 🤓

I tried different cables and ended up putting the HDD in the computer, connected directly to the motherboard.
When I play these three documents in Vegas18, they lag but not In VPX2020 or MEP2021.

I have tried many other 4k files without any problems.
My conclusion is that there seems to be some "error" in these three documents that Vegas sees but not Magix (VPX / MEP).

I have plenty of recordings that I have not worked out, I'm going to put this project on hold and try to put together others and see if Vegas does not turn out to work just fine.

Thank you all for your advice, I appreciate it.👍

Yes, boost the RAM to at least 32 GB. I would not expect smooth playback of 4K from external drives, have you tried:

Playback of VP18 is the best so far. Also, if you want to max out, go with (available for purchase tomorrow, Sept. 17)
