OBS recordings filesize blew up sixfold

I have been recording gameplay for some years now and yesterday I also recorded some. The filesizes used to vary between 3 GB and 15 GB depending on the length of the video. A comparable video on the same map was 4 GB last time (a few weeks ago) but yesterday it turned out to be 24 GB. What has changed inbetween:
- OBS update
- Windows update
I don't mind a tad bigger filesizes, but sixfold is a bit too much and not really necessary imo. It will just take much longer for the videos to upload and my harddisk will fill up faster. Any ideas on how to put it back to "normal" filesizes? I have been searching but all answers I found on here were about previous versions of OBS and some of the settings mentioned I can't find i n my version (like CQP level). Logfile of yesterday attached.

Tried to edit the post above but couldn't find how: is it not possible to edit posts or am I overlooking something? Previously I attached the logfile from the day before yesterday, so here is the log of yesterday. And some info added: a guy I play the same game with and who also records with OBS doesn't have this issue.

You can edit posts:

Now, you're recording a 2k at 60fps video which of course will give huge file size as result. Try 1080p and see the difference.
You can also test installing OBS 27.2.4 on a separate folder (get the zip file for this) in order to compare results.
Advice, don't record directly to mp4, use MKV instead and then remux it (files menu).

Thanks, I don't see those buttons:

edit: I can see them on this post but not on the first two? Does it maybe have to do with some sort of "rank" that you need to earn, by number of posts or something?


I know higher res gives larger filesize, but what I am wondering about is why it is so much bigger than before. What's the same:
- game
- map
- OBS settings
What is different:
- Windows update
- OBS update

So I was recording the same res before, on the same machine in the same game, with the same recording settings, but the filesize multiplied by six: that's what I don't understand.

My appologies, didn't notice you're using an AMD GPU.
There's a new AMD encoder (with the help of AMD itself) so you'll see the differencies. It's on the release notes. So you're right, the file size is greater. I use nvidia so I can't check it myself.

Can you check the log files folder and see if you still have a log file from 27.2.4?
You can also report this in github as an issue. that's why i ask you about the previous logfile.

What would you suggest to make the files smaller? Currently I record at 60k video bitrate but maybe that's not necessary anymore with the new encoder?

Unfortunately I am a very simple man who only presses start and stop, I know jack .... about all the technical background stuff.

Uninstall OBS 28 and reinstall 27.2.4
It's the only way to get back the old AMD encoder.

In Github you need to provide details on the settings, log files form both versions of OBS and describing the resulting video file size because going from 4GB to 24GB (6 times greater) is not ideal. The only explanation is using diffrent settings or an issue on the encoder.
