OBS Log AnalyzerExample output
EXAMPLE LOG RESULT4.7%Dropped frames

Your connection dropped 4.7% of frames.

What the log says
Frames did not reach the streaming server in time.
One change to test
Lower video bitrate by about 20%.
Then
Run the same test and compare the new log with this one.
This example comes from the analyzer's made-up sample log. Your numbers will be different.

Start with the log from a stopped stream or recording. A log can't tell how it looked or sounded, so watch a recording too.

START FROM WHAT YOU SEE

What's going wrong?

Pick the problem you're seeing. Each page lists what to check first and how to put your settings back if the change doesn't help.

NOT SURE WHICH ONE? Start with the OBS log from the session where it happened.

FOUR STEPS

How to check whether a change helped.

01STEP

GET THE LOG

After the problem happens, stop the stream or recording. In OBS choose Help → Log Files → View Current Log and copy everything.

02STEP

PASTE AND ANALYZE

Paste it into the OBS Log Analyzer. You'll see the dropped-frame, encoding-lag and rendering-lag percentages and one change to test first. Free.

03STEP

TRY ONE CHANGE

Write down the old value so you can put it back. Change that one setting and nothing else.

04STEP

REPEAT THE TEST

Run the same scene for about 10 minutes, then put both logs into OBS Log Compare to see whether each percentage went down. Free. Watch the recording too.

FREE TOOLS · OPTIONAL $9.99 REPAIR REPORT

Changed a setting?
See if the numbers moved.

OBS Log Compare is free. Paste the log from before your change and the log from your retest. It shows whether dropped frames, encoding lag and rendering lag went down, stayed the same or went up. Both logs stay in your browser. Lower numbers don't prove your change was the reason, so keep the scene, game and test length the same.

COMMON QUESTIONS

Before you start.

01Is this for me?+

Yes, if you stream or record with OBS Studio on your own PC and you are seeing dropped frames, stutter, lag or an “Encoding overloaded” warning. You need the OBS log from a session where the problem happened.

02What is free and what costs money?+

The OBS Log Analyzer, OBS Log Compare, Speed Test, Bitrate Calculator, Gear Finder, Pre-Stream Checklist and Show Planner are free and need no account. The Repair Report costs $9.99 USD, paid once. There is no subscription.

03What do I get for $9.99?+

A text file made from your before and after logs. It has both sets of percentages, the next single change to test if a number is still high enough to suggest one, how to restore your old settings, and a retest checklist. It is written automatically by fixed rules. Nobody reviews your logs, and it can't promise a fix.

04Is my OBS log uploaded?+

No. The OBS Log Analyzer and OBS Log Compare read the log in your browser. The log text is not sent to StreamerToolkits and is not included in analytics. Don't paste stream keys or passwords.

05What can't a log tell me?+

A log records dropped frames, encoding lag and rendering lag. It can't hear your audio, see your video or know what viewers saw. Watch and listen to a short recording as well, and change one setting at a time.

06Can I download Output Check?+

Not yet. Output Check is a Windows app in private alpha. You can join the alpha list, but there is no public download and joining doesn't guarantee an invitation.

07Can I get a refund on the Repair Report?+

Digital purchases are final. We may issue a refund at our discretion. This does not limit rights the law gives you. See the Repair Report terms for details, including earlier purchases.
