VPX13 Viewing, Playback and Export Problems

Hi,

VPX13 v. 19.0.2.150

As you can see from my signature, I have what I consider to be a very high-end machine.

Using the same 1920x1080 video clips that I have been using for my examples and tutorials for years now, I can easily get VPX13 (and MEP2022) to sputter and stutter, with very slow export times with glitches in the exports.

My videos and project settings are all 1920x1080.

Video settings:

Import: NVIDIA GeForce RTX 3060
Processing: Intel(R) UHD Graphics 630 (when I have a problem, I switch to NVIDIA and back)
Export: NVIDIA GeForce RTX 3060

This morning, I dragged in 2 short video clips to the timeline in a new project, pressed play. The videos played fine but the first time, the playback marker sputtered along, stopping then jumping, stopping, jumping. That should not happen, never, ever. If my computer can't play back a simple video clip smoothly, none can.

The second time through, the playback marker did much better. It should playback smoothly the first time.

I put a 2 second cross-fade on the 2 clips and automatic playback stuttered quickly across the cross-fade, the first time. Second time, smooth.

Here is where the real problems start.

I put a template title on the first clip at the beginning that has a video clip embedded in it, like "Captions basic - Amazing." Playback sputters and stutters, even the second time. Only preview rendering solves this.

Remove the title template, put an intro on the first video clip, "Intros/Outros Basic - Flares(intro)" and playback stutters and sputters along, at least the first time, then it may play back smoothly.

Back to the titles for a deeper test. I put in one that was purchased from Magix, Nature Collection - Brush Stroke Intro. Playback stutters and sputters. Export to the Magix template MP4 FullHD 1920x1080 29.97p with no changes, movie time 14:16, export time 34 seconds, mostly just trying to render the template title, then it goes fast. The first couple of times, there were glitches or full-screen flashes during the title part, which is why I noticed this. I haven't been able to reproduce these glitches in an export since then.

To see if it's just the 25fps video clips from Magix, 2017_Intro_17 Alpha.mp4 and 2017_Intro_17.mp4, I exported each to mxv using 29.97fps for the export, no changes to the mxv export template. I created a new movie, same video clip, just used the title itself without the mp4 files that were replaced by my mxv files. Playback was still stuttering. Export time for 14:16 timeline was now 26 seconds. My old computer could do this at the same speed using VPX12.

I changed Program Settings Export to Intel(R) UHD Graphics 630, exporting the movies took 28 and 19 seconds, respectively, a slight improvement,

My 2-screen setup:

4K screen:

FullHD screen:

I tried the default view on the 1920x1080 screen and I got a slightly smoother playback, but still with some stuttering on both movies.

Default view:

The other day, I added a simple title to a clip and the associated video clip went black. I switched Processing to NVIDIA, the image came back. Switched back to Intel and the image was still there. Why? This happens often, and not just to me.

I have never seen so many posts and complaints about general viewing (intermittent blank video clips), playback problems and export problems. Each time the community goes in and tries to solve the problem by switching the display settings, looking at the source video clips, etc. Users have complained over and over again that what worked in previous versions, no longer works properly in the current versions.

I believe that the problem is with the programs - VPX, MEP and PhotoStory - and that Magix really needs to look at this deeply at the new Infusion Engine 3, amongst other problems. Something is terribly wrong.

Comments?

EDIT: For reference, the 14:16s video clip with nothing else, exports in 5 to 6 seconds.

Hi John

The results you are getting are very odd.

I leave the three Device options set to the RTX2060, preview play back lightning off, no proxies.

I have been doing some other testing with 4 1920 x 1080 clips each 1/4 screen for collage each quarter having title for the full length and exporting to 4K UHD - no problems with either preview playback or exporting.

I don't have the same Intro you have been testing with as in your image above, however I improvised with a different one - no issues with preview playback - also tested with a 4K video clip, no issues.

Similarly with a project with 1980 x 1080 video with Neat Video Noise reduction v5.5 applied - smooth playback.

My current GPU drivers are:

UHD 630 30.0.101.1340

RTX 2060 30.0.14.7275 (472.75 Studio version) I do have to update these to 511.65

Do you have any Windows Graphics settings set for VPX ? They are no longer necessary for VPX13 and MEP/MS 2022.

Hi John EB,

Thanks for taking a look. I think that part of the problem may be mixing 25fps with 29.97. The Magix intros and and titles with video clips are all 25fps. However, I am still having problems with the converted Magix video clips (25 to 29.97 mxv files) so the problem may be elsewhere, possibly with chromakey alpha.

Windows Graphics settings? I have never touched these settings for VPX or any other program.

Hi John CB.

I have had a few problems with blank screens where I have had a notification that a plugin has lost it's settings. (actually MEP lost the plugin) I have made a comment to Magix Redaction on the latest feedback page for this update. I am also getting some stuttering when adding some titles that are 3D. I think it could be a communication problem with the Xara plugin as it is fixed in MEP but still needs the Xara plugin. MEP is also sometimes losing settings when a plugin is used multiple times. For me, a good example would be the Brightness / Contrast plugin or the sharpening plugin.

It just got worse. After exporting my project. Upon playing it back last half of my titles had disappeared.

Looking at the project I noticed they all had an added effect 'Brightness / Contrast' added but not just half of the titles but all of them. It must have happened while the project was exporting. I can't think of another reason why half should be affected on the finished file but all of them had the same problem when looking at each title and every one of them became invisible on the project monitor until the effect was deleted from each one.
