Hello there! I have a problem with AVI files captured via OBS when I'm working with it in Vegas. But when I capture video via Fraps, it looks fine. There are 2 problems actually:
1. Lagging and freezing when you trying to play different moments at time line.
2. Sound track in Vegas is larger than video track, and it always goes behind the video.
I made a video to describe my words. It actually starts at 1:08 and happens several times.
Provide us the MediaInfo data about this Fraps-captured video.
Though the OP didn't mention it, it looks like from the uploaded video that Vegas Pro 13 is being used. Rather important because back in VP13 days there was no File I/O 'Enable legacy AVC decoding' option.
True. That's why MediaInfo data of this Fraps-captured video can help analyze the issue. In other case, I just checked the Fraps site, and the last update release was 2013.
There are pretty the same issues in version 21, tested yesterday.

I just did another 1min video via Fraps at the same game. Here is the comparison of OBS and Fraps captured videos.
I'm not familiar with the codecs for AVI, especially from Fraps, but I think it is the specific additional codec 'fps1' added during installation?
How about the OBS alternative recording? is it stable?
Another I notice is Variable Bit Rate, and quite confusing number: Frame Rate 120 but minimum 24 and maximum 30?
Many recommendations around this is to rewrap it using Handbrake or Shutter Encoder, at least stabilizing the frame rate to become constant. Could be this issue that makes the screen recording read in flicker.

Due to Fraps site, indeed, there is the specific additional codec 'fps1' added during installation. But you don't see it actually.
I did record in mp4, it works totally fine. Just have problems when recording in AVI.
About bitrate it's the same thing on both video, and the only one is lagging (OBS one), the 2nd one (fraps) is totally fine.
Extract audio and video from the container and add them separately to the project. As an option.
The mediainfo on the left is codec salad.
It's a hobbyist creation.
The components are mutually incompatible by any standard I am aware of. No, Vegas won't import it.
You "might" try Shutter Encoder or ffmpeg command line to unbake this one; otherwise, stick with mainstream formats going forward.

- AVI wrapper
- .h264 AVC video
- Dolby AC-3 audio
- Variable Frame Rate
- Level 6.1 (?!)

Why do OBS doing this salad then :c Maybe there is something wrong with settings?

That has to be the best question asked on the forum this year. Welcome to the discussions.
Without too much backstory, there are Licensed and Open Source Encoders.
OBS uses open source code and encoders. By the time you jumble all the possible flavors of free codecs and various containers, there is only a small chance of actually getting something "right" for Vegas, which historically uses licensed commercial encoders.
So the outfit that licenses the codecs to commercial users, called MPEG-LA, and the ones that issues various open source "licenses" are often at odds with each other, mainly over the exchange of money.
The solution for your OBS settings is simple:
The h264_nvenc encoder will never support the AVI wrapper you chose, because it does not use VFW/AVI architecture, which preceded the NVENC (Nvidia) hardware encoder by 20 years or so.
h264, a registered standard format supports MP4 and MOV delivery wrappers, for most purposes.
Don't expect to understand it all overnight; in a way, hobbyists who use open source solutions face a bigger learning curve and more choices than those who start and stick with registered formats, such as prosumer videographers.
On the other hand, don't expect the guys who write this stuff for free to make smart choices for you; if the defaults don't work, check back in and Search the Forums. Plenty of discussion about OBS.
Maybe the Fraps fv1 codec you downloaded shows up in the OBS dropdown list of encoders. Worth a look.
Also don't think level 6.1 can be GPU decoded, at least by NVIDIA, so this choice of settings is really counterproductive.
I agree.
Unless one is working with 3840x2160 or greater, there is no expectation that one would be using Level 6.2.

Oh! There's the 800 Mb/s consideration, too.
Many of us mortals who use cameras manage to squeak by with Level 5.1 or so.

Thank you Mark for such a big answer above! Unfortunately, I don't have Fraps codec called FPS1 in OBS :C I guess it uses only internal codecs.
In this way, if I want to record in AVI and edit it in Vegas, I should choose the correct codec, right? What is it, then? Seems like not everything is working since I tried several of them. There is a list of supported codecs in OBS below. I chose "Show all codecs (even if potentially incompatible)" just to see everything OBS can offer.
Of the VFW / AVI codecs in your list, I have marked four common ones. I would test MagicYUV, since it is still maintained and has a version for Vegas. There are other Video For Windows AVI codecs you can install on your system.
If I wasn't fully retired from teaching, I would ask why you feel compelled to record in AVI? Something you saw on the internet maybe?
Remember that VFW codec architecture is now 30 years old, and captures files that are many times the size of their LGOP interframe counterparts.
It seems that most gaming enthusiasts are using the Hardware AVC and HEVC encoders for speedy captures, such as your Nvidia NVENC, in their appropriate containers, of course ;?)

I just tested codecs you mentioned and non of them are working :C I can't add them to Vegas due to red stop circle instead of my cursor. Three of them are lagging even when watching the video, and the only utvideo codec is not lagging.
The reason why I wanted to record in avi is the picture itself. Many years ago I saw the game video and liked it a lot. Since then I'm trying to catch that picture. I don't know how to describe, but seems like it has more contrast, deeper, some kind of grain. MP4 is more smooth anyway, even if you try to match up the color.
The image on the left above is clipped, giving the appearance of increased contrast and saturation.
It is probably the result of someone not correcting the RGB levels of their AVI capture during editing to REC 709 for output delivery.
But it's not necessary to record your gameplay in AVI at RGB levels in order to make it stand out like that.
If you like that "effect," you can easily duplicate it by adding a "Studio->Computer RGB" fx filter to your right hand image as I've shown in the video below.
You're not alone if you prefer the contrasty image, but it has 16% less dynamic range than the one on the right, which was captured and edited correctly at REC 709 levels.

Lots to learn, and it doesn't always make sense, you almost had to be alive in 1965 to understand the history of teevee and video fully. It's covered in this article, which is worth reading in full.
Same demonstration as above, with clipping indicators added.
