Question / Help Offline recording with NVENC messed up?

I know nothing about all these little settings for recording.

I went by somethings I read, trying 50k bitrate with no custom buffer so same buffer, CBR and CFR both on, NVENC Preset to HQ, Encoding profile High, and after a while of recording, I go to play it with VLC, and it doesn't recognize the format!

It seems this would just be easier to stream it and then download it from Night or YouTube.

...more info...

If I only do a short record test like 20 sec, but do a much longer one taking 4 gb, then I can't play the file.

VLC sucks playing back big files, use media player classic and be happy.
I'm not kidding right now, there seems to be a bug in VLC and it cannot open things above... er, well, some size. Like 2.5 or 3gb. Sounds like VLC still thinks we're in the era of FAT32 limitations.

Post your log file, and create a small .mp4 that you've confirmed doesn't work, upload it to a filesharing site (like Mega or the like) so we can download it ourselves and see what's wrong.

Don't use NVEnc's High Quality preset unless you have a Maxwell-based GPU. I.e. GTX750 or GTX750 Ti. At this time, all other Nvidia GPUs are Kepler based, and the NVEnc chip on Kepler isn't fast enough to do High Quality at most resolutions. Use the High Performance preset instead.

Make sure that Constant Frame Rate is on, too. A lot of your problems could be explained by CFR being set to no/off instead of on/yes like you said.

And OBS can save in one other container format besides .MP4. You should make sure you're saving in .MP4.

I regularly record longer Guild Wars 2 gameplay with nvenc, 30k bitrate, cbr off, cfr on, nvenc preset high quality, mp4 format. GPU is GTX 670, CPU is i5-3570k on 4.2 GHz. 2-3 hours one video. Resolution 1920x1200. All footage is playable with media player classic and vlc, and no issues with dropped frames or other nuisances. Perfectly smooth running video. For me, the perfect setting for local recording, since OBS has almost no CPU overhead in this configuration.

I know but I didn't have that problem 1 1/2 years ago so didn't end up here, I am afraid :p also here u go:

This is mostly for youtubers but read all () if you are a streamer - hope this is a good setup for you like it is for me!

Encoding - https://origin-us.gyazo.com/081744ec895e7efc3cdc20c1e2e51ee4.png

CBR: off
Quality Balance: 10
Max Bitrate (kb/s) 1000
Enable CBR Padding
Use Custom Buffer Size: on
Buffer Size (kbit): 0


Broadcast Settings:
File Output Only
Find an easy accessable folder or make one for ur videos - make sure to save as mp4 if you want that and name them something (same with replay)
Replay Buffer Length (secounds): 1
(and ignore replay, it's for streamers, if you stream aswell then read these messages - find a good spot for ur replays if you wish to upload them later)

Take custom and set it too ur computer screen size, most common is 1920x1080 - if you don't know, go to display settings on ur computer and find out.
Resolution Downscale: None (1920x1080 - in my case)
Filter: Bilinear (fastest)
FPS: 60
Disable Aero: on

Skip audio as it's all up too you there, we don't have same headset and taste her im sure.
Same with hotkeys, skip too advanced.




Advanced: set to deafault and then change -https://origin-us.gyazo.com/11d25cd8702f879d7f76b1118efa62c8.png



Process Priority Class: High



x264 CPU Preset too: Ultrafast (for streamers - keep it veryfast)

that's it, ignore the rest under, if you're a streamer u should research up the 2 under urself, not really needed though, u can do fine without them, but they can help u be more proffessional.
