Question / Help Camera drops quality on OBS

Hello, first time here with a big problem!



For my streaming and recordings I have a Sony Alpha A5100 camera with a legato camlink 4K, but I have noticed that for some reason, the quality of the image on the stream and the recording is like… worse than recording video directly from the camera itself.



I have trouble explaining, but it feels more compress and with less frames, I have uploaded an example when you can see a recording directly from my camera, one recording using the native program of camlink and one with obs. https://youtu.be/BmNEDu2pdH0



What could be the reason for this? My instinct says it must be something with the capture process, but I’m not sure.



If you can help, I would be in your debt. Thanks guys!

The a5100 has a few known issues. One of which being that if you have it set in Picture mode, the HDMI output image quality will be visibly worse. To get best quality out of it over HDMI, run it in Movie mode. It does not have to be recording internally, just set to Movie.

The problem with this is, there's a firmware bug which ignores the 'skin smoothing off' setting in the camera's settings unless you're in Picture mode, or actually recording internally (which will cause the overheating issue a5100s are known for). The workaround is to VERY SLIGHTLY zoom in, just the smallest amount possible. It will not significantly degrade the image quality, and will force the skin smoothing setting to be respected.

Beyond that, it comes down to manual settings for ISO, exposure, making sure you're running NTSC output (for 60fps, if it's set to PAL it will cap at 50fps).

Hey guys. I’ve got the a5100 but it will only output to hd60s+ in 1080i, when I switch to 1080p there is no output at all? Any ideas

Plug the camera into a TV or monitor and set it at 1080p. If it outputs video to the monitor, contact Elgato for support with their capture card, as they know their hardware a LOT better, and it is almost definitely a problem with the HD60S+, not the camera.

Possibly something with the color sampling method you're using in the VCD source properties; I know that some Elgato products have bandwidth issues when you try to force them to YUY2 on high resolutions (especially over USB, and p is double the bandwidth of i). Can also try setting it to YV12 or another lower color-sampling-fidelity mode.

Have you solved it? My a6000 can't output via hdmi to video switcher when set to 1080p. It does send signal at 1080i, but i dont what an interlaced video since it produces ghostlike moving subjects

It is easier to solve than you think. I had the same problem with my sony a6000 but and I found this advice:

Just turn your camera mode in movie mode and choose there the manual option. Thats it ;)
