Question / Help A SMALL CHURCH NEEDS HELP: OBS Dropping Frames on MacbookPro & Other Problems

[LBC Livestream]

Hello. Our church recently needed to livestream/record our services due to the quarantine order. Because our church is relatively small, we really didn't have a budget.

SETUP
- 2 iPhones running OBS Camera: Lightning to USBC
- Media & Slides from Proclaim (Church Worship Software): Display Capture input
- MacBook Pro 2018, i5, QuadCore, 8GB
- USB Audio Hub: Line-In from Soundboard.

PROBLEM
- The video recordings seem to be lagging. According to the OBS data, we aren't getting all 30 frames in. Below is a screenshot of FPS when nothing is recording. It usually is between 12-17 FPS when recording. CPU is usually 1-5%.

- Also, the third time we recorded, one of the OBC iPhone Camera became unsynced with the audio.

QUESTION:
- What can we do to enable all 30 FPS?
- What can we do to prevent the OBS iPhone Camera from un-syncing with audio?
- What can we do to prevent OBS from randomly crashing?

OBS LOG FILE
- I have included 3 log files during the last time we recorded.

EXAMPLE SERVICE
- To see our first attempt, you can check out our service here.


Thank you in advance to all who can help.
In Christ,

I do not know why the crashes are, I don't see anything obvious in the logs...As for your issues with unsyncing, you might want to consider using a network cable to livestream. I've noticed on my Macbook Pro 2017 that for some reason, streaming over wifi causes massive amounts of lost frames (10-15%) and occasional unsyncing while using network cables keeps everything working very nicely.

God bless you & your church going on with the service.

Thank you. We are actually not live streaming, because of our internet speed. Just recording. We believe the syncing problem is coming from the iPhone inputs. Sometimes the feed comes in slow and sometimes fast, even though our audio is constant. We are not sure how to fix this.

You're overloading your GPU. Lower your canvas resolution to 1280x720.

Not sure if I can help with your problem - but I wanted to say thanks for giving me some ideas for our services. We have never streamed before, so this is new to me. I am in charge of OBS/Proclaim. We use a Mevo with the GoPro2OBS program to stream to OBS. We have our audio piped in directly from our mixer (but of course running through a hum eliminator first). Because our video comes from the Mevo (over WiFi) and the audio is direct, I had to add a 1900ms delay to the audio to get it to sync. Feels extreme to me, but it aligned perfectly. I actually used a Metronome app on my phone that plays audio while it flashes the flashlight - which helped me sync audio perfectly.

I had to laugh because each of your people in the stream - the music director, piano player, pastor, and woman/man singing - we have the same exact individuals and very similar camera shots.

I would change my settings->output to advanced mode and change my encoder under Recording (since you aren't streaming) to one of the Apple hardware encoders.

I was browsing through OBS Church forum and I noticed you post.

My home church is also small and our issues in 2020 with Drop Frames was due to internet speed and jitters/lags. We are using a Macbook Pro 2020 Intel Core i5 (currently still running Big Sur). Previously we were on Comcast broadband with 100gb download and only 20 Upload - This was causing a lot of drop frames and video issue with the live stream. We tried to work around this by using mobile hotspot (11gb upload speed) and it was the same drop frame and video issues but surprising some days the hotspot was more stable (less jitters/lags). We had to upgrade our Internet, but because of Comcast limitations the most we could get was 40gb upload speed (see the image below).

1, Check your UPLOAD internet speed, you need at least 40gb UPLOAD speed for 30 fps.
2. Make sure your using Ethernet cable to the computer NOT Wifi - DON'T USE WIFI for Stream as you won't get the Upload speeds you need (therefore will experience drop frames and bad video quality).
3. Check your internet for jitters/lags: https://www.fusionconnect.com/speed-test-plus/ping-jitter-test
4. Make sure you close windows and web browser apps on your Macbook that you don't need to use for live stream as this will affect your CPU usage. We only have Restream.io and OBS Studio open. We use the Bible Plugin for OBS.
2. My church is using a security CCTV camera (I know this is very bad quality) for now until we can get budget to upgrade to Birddog 4K PTZ camera. I hope to get our camera upgraded in 2025. Here are my specs (see pictures attached).

I hope this bless you and your church.

also get a 4K HDMI or SDI cable this made or CCTV video quality 20% better, clearer, and little sharper.
