OBS Recordings have Massive File Sizes

[SkyeRangerDelta]

Hello all,

I love OBS Studio, I have it setup so that it utilizes my GTX 1070 as part of the encoding process and my recordings look gorgeous, 1080p at 60fps, but my file sizes are insanely large. I dont have the best internet which is why I won't stream, so I record and upload to YouTube what I want. But I don't have 5 days to wait for a video to upload. I recorded a 23 minute video of some work in Revit 2018 and it came out to be a frickin' 8.3GB video.

I compress in MP4, and if you're interested here are my output settings: http://prntscr.com/fkon5o

My PC specs are under "view more info" on my profile.

If anyone has any advice on working with this file size, that'd be much appreciated.

MP4 is just a container and does not compress at all, that is the task of the video encoder and the particular codec used.
A bitrate of 50k is a bit overkill, don't you think? Try it with about 10% of that, even that should be overkill in terms of quality for a FullHD recording.

You also may want to use the newer and better OBS Studio.

yes change your qualty settings my files are very reasonable

Yea I'm thinking of dropping the bitrate, I just found that out from one of my streamer friends.

What do you mean by better OBS Studio? Does this thing not auto-update?
*locates newer version via the great mind of google*

I use a program called VidCoder. It re-encodes videos to a YT friendly codec. You can also lower file sizes with it at the cost of a (slight) compression.

I just dropped the bitrate from 50k to 20k and the quality seems alright and the size was significantly reduced. I got a 1m video and it was only 136MB which I dont think is bad. If was lower, I'd like it more...alot more.

When you say 1/10th, that just seems like it will slay video quality will it not?

[HypersleepyNaputunia]

1 minute video should be in 3-10 mb range or so. Ill run a quic 1 minute test

5.98 mb for 1 minute

bit rate 2500
encoder x264
high quality medium size
flv format

The file-size of a video is determined by the bit-rate, not the file-type (mp4) or what ever everybody else is talking about.

https://support.google.com/youtube/answer/1722171?hl=en
According to this (Click on Bitrate to bring down the table) videos at 1080p should have a bitrate of 8Mega-bits per second for 30 frames per second, or 12Mega-bits per second for 60 frames per second.

OBS's bitrate is in Kila-bytes per second, so you should set the bitrate to 8000 or 12000, but I recommend having a bit of a buffer since it is possible to scale-down, but impossible to scale up. So your should use a bitrate of 9000 or 13000 (The latter is what I use)

Reduce bitrate.

[SkyeRangerDelta]

I'mll probably shoot for 13000 and see how that floats.

Just recorded a 4:13 video of stuff in mp4 format at 13Mbps and it came out with a 400Mb file size, so this is definate progress. YT estimated it would take 2 hrs to upload something like that. Sigh.

I do plan on looking into Handbrake just to see how it does. I'm more interested in keeping quality over file size than all out UHD quality. Internet upload speed can't take that. The smaller the file size and the better the quality, the more happy I am. Of course, then again thats the ultimate dilemma, small file size for ultimate quality.

5000 bitrate looks like trash on a 1080p60fps settings. If you mean 40000, maybe, but it's not great.

OP, just do what I do. Roughly 30000 bitrate, 50fps. It'll drop the file size immensely.

Uh. Recording software records in an uncompressed form. You need to take the files to task with proper editing software.

Got any recommendations?

Never have I agreed to 5,000 bitrate. Look closer, 50,000 bitrate.

I have tested in 50k, 20k, and now 13k. 13 doesn't look as pristine, but it's alright. I'll see what I can do on 50 fps.

Recording, no. If it handles your frame rate and dpi, all good. As for editing, I would rather not say as I use a dark horse, and don't feel like ridicule. Most of the good ones offer a reasonable compression rate. Mine keep a 1080p File at 60 for 30 minutes right at a gig. Which I fine acceptable. for 1920 x 1080
