Part of clip laggy in preview and render
I feel like I’ve searched the entire internet for the solution but seems no one has had this specific problem?
I use Sony Vegas 14 and I’m trying to create a montage, it’s a video compilation consisting of about 25 or so clips, ALL of them recorded on the same fps and resolution, recorded at 60 fps, 1920×1080 and those are the settings I chose in the project settings, also disabled resample on all the clips. All clips have the absolute same settings on everything but some are laggy and some are smooth. This applies to both the preview and the results after rendering.
Like 70% of the clips are butter smooth but the rest of them are choppy, like 25 fps, and weirdly some of the smooth clips become laggy if I split them for merging into one another etc
This has happened on my previous montages and I can give you examples if you can bare the cringe, I worked 4 hours on this and really want it to be good but the laggy clips ruin everything. Does anyone have any idea what this could be?
Thanks in advance -

[lee tauseef] ” ….. recorded at 60 fps, 1920×1080″
Hi Lee – My guess is that VP and your System are struggling with 60fps. Is there a reason why you filmed at 60fps?

Why would my system struggle with 60 FPS if I can record it in 60 FPS just fine? As I said most clips are smooth but certain clips lag, there is no stuttering and Sony Vegas runs without any problems
My PC is not the best but I’m sure it’s not the problem, I can list the specs for you but again, I don’t think that it will be necessary -
Are you recording on your pc ? With variable fps ?
Give us a mediainfo of a clip that plays bad and one plays okay !

Ole, exactly. Lee is understandably frustrated, however he needs to dig deeper to fully understand what is choking his PC with Vegas.

I did mention that some clips are smooth but if I split them into two, one part of the clip becomes laggy and the other remains smooth. So I don’t think posting mediainfo of 2 separate clips is necessary, again, all the videos have exactly the same recording settings etc. Doesn’t specifically say anywhere whether it’s cfr or vfr but maybe you can figure that out.
edit: this is one of the clips that were actually laggy in preview and render originally and all of them are recorded through Shadowplay. Not quite sure if shadowplay records cfr or vfr because it doesn’t say that anywhere in the shadowplay options menu

We need to se mediainfo like this – not only frontpage !

NLE’s don’t like variable fps – try convert som recording with Handbrake to constant fps !

I thought that issue was related to audio syncing and did not involve random lags when importing them on Sony Vegas.
God if I have to use Handbrake to convert video then I’ll have to convert every single video to cfr which would take super long, I guess it’s my last choice beside posting the montage as it is

t would be nice to see mediainfo – so we can see if you record 60 fps or not!

Oh, sorry about that. Here it is:
I can see that maximum and minimum fps values are different, could that be the issue?
