So every time I play the media source when I'm streaming, it will lag the entire stream and will also lag the program. The audio will also be distorted.

1. OBS is not running as Administrator. This can lead to OBS not being able to Game Capture certain games. If you are not running into issues, you can ignore this.
2. Having the YUV Color range set to "Full" will cause playback issues in certain browsers and on various video platforms. Shadows, highlights and color will look off. In OBS, go to "Settings -> Advanced" and set "YUV Color Range" back to "Partial".
3. Update to Windows 10 2004 (if available) per https://obsproject.com/blog/five-simple-tips-for-new-streamers
4. Your log contains no recording or streaming session. Results of this log analysis are limited. Please post a link to a clean log file.
To make a clean log file, please follow these steps:

1) Restart OBS.
2) Start your stream/recording for about 30 seconds. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.
3) Stop your stream/recording.
4) Select Help > Log Files > Upload Current Log File. Send that link via this troubleshooting tool or whichever support chat you are using.

Hello. Thank you for your reply. I'm seeking help as by media source was lagging whenever it is active. The audio will also be distorted. For more information regarding the properties of the media source can be seen above.

Try increasing the Process Priority in the Advanced Settings. If the issue persists then provide a log of when the issue is happening.

SOLUTION

Hi guys,

I'm pasting this here as I've just solved a similar problem after a long time going round in circles, in the hope that someone's search engine will land them here and save them the days its taken me to work this out. Problem: obs (and whole computer) grinding to a near halt when adding .mov or .mp4 video background.

I eventually remembered a problem from 15+ years back where I didn't have video Codecs needed to play video files because I couldn't play .mov and .mp4 video in bog standard Windows Media Player. So i tried to just "play the file" outside of obs and sure enough, blank screen.

There were two stages involved in fixing this. You might only need the second step.

My rebuilt / fresh install of Windows 10 Laptop did not have the following:

1) The correct Graphics Drivers. My Laptop comes with Nvidia dedicated GPU and I had installed those drivers, but missing piece was the integrated Intel Graphics Driver. I overlooked this because I did install Nvidia's correct driver thinking that was the job done. I went to Intel's website to update this (and all other intel devices and chipsets inside my machine) https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html

2) Furthermore, it was this step that highlighted the above was the problem, as I got a warning flash across the screen upon my first attempt of installation which said "Setup has detected that you are using the generic graphics driver "Microsoft Basic Render Driver" for your primary GPU" (my Primary GPU was the inbuilt Intel Graphics card). So I installed the K-Lite Codec Pack from: http://www.codecguide.com/configuration_tips.htm?version=1595

3) I went to my computer manufacturer's website and ran the "Driver Update Tool" where it downloads a file onto your computer, runs a scan, and suggests a myriad of updates you are missing. So if you are on Lenovo, Dell, or whoever, they'll have a support > Drivers (or update my computer) page that, when you find it, will save you a lot of searching and time and bring you up to date for the build of windows you run.

I'm sure that for me it was 1 followed by 2 that helped me the most, the third is optional but I recommend it over the "Device Manager - Update Driver" option because, frankly, it just does not seem to give you the newest drivers from your manufacturer but some other 'make-do' equivalent from windows.

My computer is working well now and I hope yours does too!
