thanks for the tip, but I don't have a UHD monitor and I'm not planning to buy one. I do not need him. I have two monitors. One primary LG 1920x1200 and the other Samsung 1280x1040 on which I have a Vegas preview window. Both have analog connections. It's enough for me to edit the video. The editing output is in 95% FullHD.
 

Then you are never ever in the position to assess the preview of any NLE.

@pierre-k I've seen that very often for quite a while., it's normally near the top/upper 1/3 of the preview, it doesn't matter what FR, where the preview window is or what quality it is set at. It's not in the final render so I just ignore it.

It's the equivalent of having VSYNC turned off in video games, faster frames but torn frames. I don't think that's appropriate for an NLE preview to tear like that and maybe that was an interim measure at one stage to increase the frame rate.

With the new decoder/engine it most doesn't have a lagging problem anymore, I can playback smoothly 4K240fps AVC, if you look at the FPS counter there's very slight fluctuations, maybe at 200fps there wouldn't be, but if they have the ability to turn off that screen tearing now due to the maturity of their decoder/engine it would be an even better improvement.

If you want to see what this looks like slowed down look at my videocap in the main VP21b315 thread at the top of the board, it's very ugly

Another idea is to have an option where vsync can be switch on, in Resolve ticking this option does that

There will be no dropped frames ever, but the highest amount of frames per second will be dictated by your monitor, so 144hz monitor when playing 240fps footage on a 240fps timeline, the playback will be slowed down to 144fps in the preview, it won't be playing in real time, but ofcourse a 120fps project will play perfectly. Just an idea, not entirely necessary if you can get rid of the frame tearing by other methods

VEGAS has a Vsync option as well in preferences.

Vsync only seems to work for full screen preview.

vsync only works for full screen. Not for the preview window.

Even other options such as deinterlacing and adjust level do not work in the preview window. Isn't that a shame?

@VEGASDerek

Hi Derek.

Can you please tell us if it is possible to activate vsync for the preview window as well? And why is it still off?

Thanks.

To come up with a 30 fps testfile is a nice idea. But with 25 or 30 fps and no motion blur from a camera the preview will never be smooth, especially not on a progressiv system and a typical PC monitor.

I wonder what your priorities are. Can you edit real live footage with the existing system? For sure you can. Would it be nice to see improvements here? For sure that is true too.

However, given your limited preview chain with a Samsung 1280x1040 I wonder what you are looking for. As said, this is not the hardware for a supperior workflow. Is is a calibrated unit at least? That would be more important to be able to asses video footage really. And as said earlier: if that is so important for you, invest in an appropriate UHD monitor that can be calibrated. And a Decklink card, what improves not only the preview quality today with Vegas, but allows also a qualified assessment of the color of your footage.

as I already mentioned drive... the problem with vertical synchronization in Vegas is also when using a 1920x1080 projector via hdmi. Apparently it doesn't work on any monitor.

I would like you to show me that on your uhd monitor there is movement in the preview window without any problems.

What I want is clear. So that the preview window of Vegas does not cut the image vertically during editing. Buying a uhd monitor or a Decklink card for this seems like an unnecessary investment to me.

I am convinced that it is a software thing that arose in the first versions of Vegas and no one ever addressed it. If it works in games or in Resolve, why not in Vegas?

I don't use fullscreen on the entire monitor where the image is fine. Fullscreen works great even without a uhd monitor and Decklink card. I am troubled by the preview window, which is not in order.

It is up to you to check the preview with other hardware. And I did not say that there are not problems. I said, what we have it is good enough for even professional work. I use both Ultrastudio 4K for my laptop, but also the Decklink 4K extreme 12G for my desktop - to grade on my calibrated UHD monitor. In my understanding that was not unnecessary investment, for the background of professional work.

Yes, you are. But I wonder what is the outcome to your final products really. If ther e is a impact at all.

But it is up to you can stick to consumer hardware. Beside Vegas I have here also both Resolve and EdiusX here. Both tools support Decklink cards for a professional background - Edius for broadcast stations, Resolve as serious grading ap.

What harms your work more is to use uncalibrated monitors, accepting unidentified luminance and gamut shifts. One should stick to the really important points.

I don't edit minecraft.😂

Maybe such improvements will come as part of the video engine overhaul. We already got the ability to zoom into the preview window which was long overdue.

I don't want to open another topic here about the quality of the output product.

But I will briefly explain the basic facts. If my customer needs to post a video on FCB or youtube, where the quality of the original video is greatly degraded, calibrated monitors and Decklink cards are not needed. It's a useless investment. I will have a wonderful feeling that the video is color correct and the gamut is exactly as I wanted, but FCB and YouTube will still invalidate my result.

The customer is not interested in the color range, but whether the video can be interesting and whether they like it. This is the most important.

And what will think your customers about vsync? If they do not care about color, what will they say about such a minor preview issue?

But I hope that there will be some improvement for vsync too. My assumption is only, that this has low priority at the moment, since the development team is busy with the new video engine. But who knows...

Sir colleague. You are provoking me. (fun)

The case of vsync is only about the comfort of editing.😉

I know that this is about the comfort of editing. But unfortunately, that is what we have.

And true is, that you make other - quite significant - compromises.

I may be wrong when I stated, that the development team may have other priorities then vsync. The future will show.

I agree with you. Compromises for quality on social media annoy me. It is a degradation of the author's work.

Now that the new engine is being created is the best time to upgrade the Preview window.

Maybe. But that is the decision by the development team anyway. Not mine.

@Gid can you supply the project demonstrating the issue? The "bar" project.

@Reyfox I used Vegas Chequerboard, 10secs UHD, (there's nothing on the audio track so no reason for it being there)

I don't see this all the time, not with 'reg' videos, I like to play with fxs & movement of some kind, so it's normally when something like this is moving across the screen, it's hard to pin point but If I can find a 'reg' video that does this I'll post it on here.

This isn't a video, it's just a png ball keyframed to travel left to right across the screen,

I don't remember how long I've seen this but like I say this is just on the preview window not in the final render so I just ignore it.
