Good, just make sure the Enable Hardware Decoding for supported formats box is checked too. I forgot to mention it above.

for some reason I can't find these settings all I can find are these.

it stopped the preview lag before, and now when I record with obs And import the video files It started lagging again. I think I changedthe settings on accident

It was fine a couple of hours ago, I was so happy when the preview lag stopped and it's back at it again.

i changed the settings because the quality was really shitty. So I changed it to look better and the preview lag was insane. Did I do something wrong?

Evidently the File I/O setting options have been changed slightly in VP18.

Go into the Vegas Help Menu: Help > Contents & Index (Or press F1) > Type File I/O in the search box & click List Topics. See what it says about the options you have available. Might need to enable the Legacy AVC Decoding.

If you're still using the recording settings in the screenshot above, you should be OK since it's the Basic View. But, since you're recording @ 144 FPS I suspect your encoder is getting overloaded & lagging frames. I think you'll have much better go of it recording @ 60 FPS.

From Vegas Help for those 144FPS recordings you already have:

Working with high-frame-rate (HFR) clips Working with high-frame-rate (HFR) clips

If you want to use high-frame-rate clips to create slow-motion effects, you need to adjust the clip's playback rate to conform to the project's frame rate.

You can use the Project Media window to set the clip's playback rate when creating events, or you can use the Event Properties dialog to edit events already on the timeline.


​
Open Adding HFR clips from the Project Media window

  1. Add your clips to the Project Media window. For more information, see Using the Project Media window
  2. Click to position the cursor in the timeline where you want to create an event.
  3. Right-click the clip in the Project Media window and choose Add at Project Frame Rate.
    An event is created at the cursor position, and the event's Playback rate value is calculated to allow the event to play back using the project frame rate. For example, if you add a 120 fps clip to a project with a frame rate of 30 fps, the event's playback rate will be set to .25.
    Event playback is limited to a range of .25 to 4.0x playback. If the event needs to be modified beyond that range, a velocity envelope is applied. For example, when using a 240 fps clip in a 24 fps project, the event's playback rate is set to .25, and a velocity envelope is applied to achieve the required playback rate of .1. In these cases, the event's audio will not play in sync with the video.
    If you need to check or adjust your project's frame rate, you can use the Project Properties dialog. For more information, see Setting project properties
Open Setting the playback rate of an existing event

  1. Right-click the clip on the timeline and choose Properties from the shortcut menu.
  2. On the Video Event tab of the Project Properties dialog, click the Conform to Project Frame Rate button.
    The event's Playback rate value is calculated to allow the event to play back using the project frame rate. For example, if you add a 120 fps clip to a project with a frame rate of 30 fps, the event's playback rate will be set to .25.
    Event playback is limited to a range of .25 to 4.0x playback. If the event needs to be modified beyond that range, a velocity envelope is applied.

In these cases, the event's audio will not play in sync with the video.
    If you need to check or adjust your project's frame rate, you can use the Project Properties dialog. For more information, see Setting project properties
  3. Trim the event end to adjust the event so all frames are visible. For more information, see Adjusting an event's length

I have a 2560x1440 display with a 144hz monitor. I record at 120 fps for Minecraft and the videos I record are very smooth. Now, other people don't have this problem but I do. I put my video onto the sony vegas editor and It's uneditable because of the insane preview lag. It skips frames. I want to become a Youtuber but this one problem is keeping me from uploading videos. I don't know how to fix the problem, but if there are fellow OBS and Vegas Pro users out there, please help me out.

I also record at a high framerate (480 fps) and use vegas to render the frames down for a good motion blur affect so here are some tricks I have learned (btw Vegas just has general problems with preview lag)

Vegas pro likes the mp4 format best so record in that
Set your preview to half or quater (doesn't affect final render)
Go to options>preferences>video and try setting your Dynamic ram preview to 0 or half you system ram
Go to options>preferences>video and try turning off gpu acceleration or keeping it on whichever helps the most
Hold shift and click on options>internal type in multi and hit space and set Enable Multi stream render to TRUE (turn it back to false if it makes things worse)

You can also make a proxy using ffmpeg

if you need further help with obs settings that are good for high fps recording you can contact me at nicholas#7354 on discord
