Vegas Pro 23 – Laggy Preview on High-End PC Compared to Vegas 18

@AbdelhadiAfa The sfk0, sfk1, sfk2 files are created to draw audio waveforms for each of the audio tracks in your media. It's been done since Sound Forge days and probably will continue.

Got it, thank you <33

Ah okay, so next time I should record with Keyframe Interval = 1 second in OBS, right? About the overlapping part: since I edit gaming videos and cut a lot of scenes, will that affect performance? Are you saying I should make separate copies of the original footage, like one named "A" and another named "B" and use them in the timeline so that clip A is for the first scene, clip B for the next, then back to A again, instead of overlapping cuts from the same original file? Sorry if my explanation isn’t perfect, English is not my native :D

@AbdelhadiAfa English may not be your native language but you understood this perfectly!

Yes, with the OBS fix it will give VEGAS somewhat easier to edit footage.

By making copies of the footage you can work around this limitation with VP 23.

Do both and hopefully you will no longer have a laggy preview experience.


@RogerS Should i do this now?? In the screenshot, I duplicated my video and split it into two versions labeled ‘A’ and ‘B.’ Is that what you mean? You can see in the yellow section that the clips are arranged as A–B–A–B–A–B.

“I don’t notice any difference whether I cut them or not, even when it’s from the same source video

It should only make a difference when you are overlapping or fading the media. Here it looks like just straight cuts.

Conclusion, issue is only annoying for editors who make videos (tutorials) from one camera take or from one screen capture recording (gameplays). For usual editing of multiple camera takes, it's no issue. Also it's common to use hard cuts when editing multiple takes and not crossfades, to avoid jumps, like in one take edits.

😂😂 Yeh right. I guess you don't actually read my comments 🤦‍♂️

@3POINT  When you've got lets say 20 events on the timeline, working your way along the timeline you cut one then drag to create a crossfade, then play that crossfade you might see it needs just a one, two or a few frames removed or added for it to flow properly, so you cut one frame off but that might not be enough so you try removing two, .... after every edit it needs to be replayed & to see it play correctly playback at full frame rate is essential.

My most recent timeline -

21 mp4 takes

but 43 mp4 events on the timeline, that means a lot of them are takes that have been split.

PS. the two longest events on the timeline got split & trimmed to reduce the timeline length, so the amount of events was more, for some reason I can't find the final project,

PPS. There's no such thing as 'usual editing',. I use 15 frame crossfades because I prefer the soft transition rather than the hard cut that is 'jumpy' .

@Gid the issue is between a crossfade of one source video and not between a crossfade between two different source videos, right?

Gid wrote on 11/5/2025, 12:28 AM

@3POINT No, It's not solely a single take split & crossfade issue but it is more noticeable on those events for whatever reason. It's also a progressive thing, the more time spent editing & further down the timeline you/I get the worse it becomes, just after opening VP the first few events can play smoothly but the 5th or 10th can start being stuttery, by the time you get to the 20th it takes 3-4 or more loop plays before it plays at full fps ...

As I mentioned proxies run smooth on all events, I get good none interrupted editing. So whether it's something to do with 4k/UHD or because VP has already processed the events/takes when creating the proxies - I don't know, I suspect the first option of VP being able to work with the smaller recoded proxies. (I've previously tried recoding all material to constant in the past so that it's all the same size & FR etc, it didn't make much difference). I don't work in FHD to compare the difference with 4k/UHD.

PS. I know what you're trying to say but the point is that when I've got 20 takes on the timeline & the majority will prob get split into 2 or 3 events, that means that it's the best part of the whole timeline that won't play correctly first time & it's hard to keep track of whether it plays smoothly between different takes or split takes. It feels like you're editing & pretty much every crossfade won't play fluidly first time.

You can't just 'conclude' this, It's wrong.

Also I use simple crossfades but I own loads of transitions, people pay a lot of money for transitions. What you essentially wrote was 'you should be using hard cuts, if you use crossfades expect problems'

I've shown that the crossfading issue is only between a crossfade (or whatever other transition) from the same video source and NOT between a crossfade between different video sources.

That the overall transition behaviour of Vegas is not optimal, we probably all know (and I lost faith that this will ever be as smooth like shown in DR).

I didn't say you shouldn't use transitions, I only said that normally hard cuts are used.

I guess I'm moving to davinci there's a lot of problems during vegas 23

I personally rarely used hard cuts in my videos. The cross dissolve can be only a few frames, but for the videos that I do, hard cuts do not work.

As for moving to Resolve, nope.... and I own the Studio version with the Speed Editor. Happy editing until you experience a problem. To think that Resolve is the cure all/be all, take a trip to their user forum....
