Okay so here's the deal. My settings in OBS STUDIO are as follows.

My CPU is an ryze 7 2700x. gpu is xfx r9 280x and i have 16 gb ram.

What I normally do is record in obs, then after done recording I remux it in obs to mp4. after i remux it I drop it into adobe premiere.

Something about VFR to CFR was said to me and I just don't understand any of it.

I brought a gameplay video in and tried to put another gameplay video no top of it which worked fine until i dropped the crop effect onto it and cropped it some. the video just froze up completely until i deleted it. What is the best way to go about this?

Thank you.
 
This sounds more like an issue with Premiere, which is outside the scope for OBS Support.
CFR, Constant Frame Rate, is an option you can set in OBS which makes created videos play nicer with some picky editors.
 
I used to record in VFR and had a whole slew of random issues and bugs in premiere until I switched back to Sony Vegas which fully supports VFR media (several years ago). The only real solution was to make sure any video I put into premiere was CFR and not VFR, so I would encode that video into CFR not VFR. The other issue is that with VFR if you ever drop below whatever your recording fps is (60/30 frames per second) you will have chunks of video missing which will make your audio sync etc..a mess when you import into premiere.
This link explains basically how it works and the differences between the 2.

FAQ: How to work with Variable Frame Rate (VFR) media in Premiere Pro?

What is Variable Frame Rate (VFR)? Variable frame rate (VFR) is a term used when the frame rate changes over time for a media file. Usually, this is done to maintain either a compression level or to have better performance while capturing or recording media. Common examples are the media...

Cheers,
 
okay so i been reading up on it, i guess i'm just stuck re-encoding using handbrake from now on, which is going to take ages. this really sucks.

obs does output CFR by default and I'm not aware that you could set it to VFR.

OBS Classic defaulted to VFR and had an 'enable CFR' option. Apparently Studio does default to CFR now unless you set a specific encoder option. I was unaware of the change; good to know!
 
So what's my best option to do here? I have an older gfx card and i'm thinking that's what may be causing all of this. It's an XFX R9 280x.

Is there any way to fix this completely? better gfx card?

There's gotta be people out there that are able to just record and bring straight into premiere without having this problem.

Again, this is a Premiere problem, not an OBS problem. We cannot help you.
You would be best-served by contacting Adobe support. This is out-of-scope for OBS Support... OBS recorded the videos fine, the issue is happening when you apply an effect in Premiere.

I was told it was becasue of the variable rate.

OBS Studio does not record in variable framerate by default since OBS Classic, back in 2013 or so, unless you specifically turn it on with certain custom encoder flags. It records in constant framerate. The issue is not because of CFR/VFR. The discussion above was tangential, sorry to confuse the matter.

so everyone that uploads to youtube pretty much re-encodes?

You aren't just uploading to Youtube. You're editing in Premiere first.
Again, this is an Adobe Premiere problem. We can't provide support for Premiere here. Contact Adobe for support with their software.
 
The issue IS VFR and using that type of media in Adobe premiere, anyone questioning needs to read the first link I posted. Thank you. My best advice to you would be to make sure your video is being recorded into a CFR not VFR, now CBR which is Constant Bit Rate will also present various issues from time to time in premiere, not as much but they will happen. If you read the first link it will go step by step and show you how to verify the type of media and whether or not it is constant frame rate. What it comes down too is Adobe is picky and wants a media source that is consistently the same bit rate/frame rate, it makes sense when you dive into this VERY known issue on their forums.
 
I have found that my MKV files are constant frame rate, but when they are automatically reMuxed into mp4 (for Premiere Pro) that is where they become VFR - if there is some way of changing the ffmpeg instructions (which appear to be behind the scenes) I think this could be corrected. Although Premiere Pro CAN work with VFR I find audio slide and a general lack of stability working with this media.
