Inability to record in 8-bit (NV12) and be color accurate to the source

Yesterday I fiddled around with OBS for some time to dial in more refined settings to fit my needs However I quickly discovered that running either NVENC H264, HEVC or AV1 in NV12 Rec. 709 Limited ends up largely impacting the output's color accuracy as I view it in a fresh install of VLC after. From what I gathered thus far, seeking help from a few other people, is that 10-bit P010 Rec. 709 Limited with AV1 results in exactly the result I am looking for. The strange part here however is that both my displays are in 8-bit SDR mode, one of them being HDR capable but turned off. This makes me to believe there's something fishy going on behind the scenes that possibly tricks OBS into needing a 10-bit color format in spite of the source being in 8-bit for colors to match....

screen tearing with Avermedia GFC573 capture card and cloned display capture

So I tried to record some TF2 gameplay and I've been getting screen tearing on the capture card side (avermedia GC573) when I was cloning that with my main rig's monitor which is running in 144Hz + GSYNC on. Capture card is 60 Hz. So this is probably due to mismatching rates so would I change my main's monitor rate down to 60Hz, or should I just install OBS on the main computer too and add in a game capture and display capture source and call it a day? I'm not sure about the latter due to concerns of using up resources or losing performance....

Aitum Vertical Plugin not streaming when OBS main does stream with same exact settings

So I am using Vertical Plugin to attempt to stream to Tiktok, I have the stream key and everything all setup and hit live but nothing is being received on Tiktok's side. I swapped to use OBS main just to see if it's my setting and Main will send out the feed and be recieved on tiktok's end. I even tried to swap so main would stream to tiktok and Vertical would send to another channel in 16:9 but the feed ended up being in Vertical mode in Vertical plugin

Is raw, uncompressed capture possible on current macs?

Is it possible to capture raw content on an Apple M1 Max Macbook Pro. In terms of other hardware, I have a an Elgato HD60 X, as well as a RetroTink4K. My goal is to be able to capture uncompressed VHS and Hi8 content. I asked Bob at RetroRGB and he wasn't aware of a means of doing so on current M1 macs and he recommended I ask here. Thanks in advance for any help.

Windows sound playback device stops working

I am having a strange issue where the Windows sound playback device, whatever it is set to, stops producing sound. Whether set to the mobo soundcard, Focusrite interface, or Voicemeeter channel, it shall intermittently/randomly stop. The only way I have managed to get the audio back has been to reboot the pc, recycle power to focusrite, or restart Voicemeeter software engine. I’m confused what my next troubleshooting step should be....

DaVinci Resolve stacked timelines shenanigans

I have a 1080x1080 timeline with camera zoomed in and movement done so that speakers would be visible in tiny window next to slides in 1920x1080 timeline. 1st pic is what it is supposed to look like, 2nd what it currently looks like being nested on another timeline. 3rd is how it is supposed to be. Both times DR Studio 18.1.4 was used. Any recommendations? I don't know what else to do...

High OBS GPU Compositing Load

I've recently started trying to setup a 2PC stream using an elgato 4KX to let me move 2 camera and some ultrawide gameplay In the scene composting 2 cameras and the game into a single scene, OBS will draw close to 30% load on my 3090TI which results in a fairly negative impact on gameplay. Is this GPU loading normal for what I assumed would be relatively light loading?...

OBS Fullscreen Projection to CRT TV: Audio and Sync

Audio is not enabled by default when using OBS Fullscreen Projector to another monitor. I enabled audio by setting my CRT TV as my default audio monitoring device and then Advanced Audio Properties "Audio and Output" to my source: Desktop Audio. However, the audio monitor output was delayed and desynced with the video being projected. Is there a better solution to this problem? I'm open to using any plugins as needed. Please and thanks. Here's some additional info on my setup and what I'm doing: https://discord.com/channels/84789673121038336/529165044009926676/1262885848886542397...

Making digital copies of physical photos.

I am looking to back up several physical photo albums for my family. I have over 100,000+ photos to back up and while I fully understand the task and data requirements, my homelab is fully capable of doing so. I have over enough space to hold over 720gbs of data Lol. My question is what is the best and most effect solution to scanning that data. Any services, specials scanners that make the task easy or is just placing on a standard printer/scanner my only solution to getting good high quality scans of my photos? Any help would be amazing and appreciate all the help...

Video Player w/ Hardware Accelerated AV1 Decoding on Linux (Nvidia GPU)

Question As the title suggests, I'm looking for a video player that can playback AV1 encoded video files with hardware acceleration via an Nvidia GPU on Linux (Ubuntu 24.04 LTS). Personally I've used VLC Player on Windows for like 2 decades, and since v3.0.18 it's had Hardware Accelerated AV1 Decoding support on Windows. I install it with winget install VLC.VLC and it just works, no additional configuration needed. On Linux however... when selecting any of the "Hardware-accelerated decoding" options I get either poor performance or a black screen. - VA-API video decoder - Poor playback performance (anything over 1080p freezes)....

Encoder Overload while using Aitum Vertical

I have been trying to track down what was causing my OBS to randomly get an encoder overload error when streaming/recording and after re-installing OBS, recreating my scenes and profile it looks like when I have anything added to the Vertical canvas I get this error. I previously was using a 3060TI but upgraded to a 4070TI Super and still have the same issue. Its pretty random but usually happens after about an hour, happens while just streaming and vertical recording as well as streaming, main canvas recording and vertical recording. Happens with OBS in regular and admin mode. Here are a couple old logs from pre-GPU upgrade as well as a youtube video time stamped to when the issue happens https://obsproject.com/logs/pHAQzoDXXpW9oaEO...

Best OBS Video Playback Recording Practices

My goal is to run a video I've made back through OBS to apply some Source Filter effects to the base footage. The filters are Retro degradation effects so end-quality isn't the most important in this specific case... but it did make me question "best practices". The footage was all recording at 4k H.264, VBR 50-60,000 kbps, 2s Interval frame, P5 preset, High quality tuning, Two passes mode, high profile. From the Source methods I tried (Media Source, Display Capture, Window Capture) Media Source was a no-go for me because it introduced stutters into the playback and recording. The two methods that worked were Display Capture of me watching it through "Movies & TV", and Window Capture after uploading the footage to YouTube and playing back at the highest possible quality (4k)....

Twitch Enhanced Broadcasting Performance Impact

I've been doing some testing with the enhanced broadcasting beta (open beta/h264) and noticed it significantly impact my game performance compared to just streaming normally. Is this expected? I assumed it would be pretty similar so long as you have available encode sessions. For reference, after a few runs of the MW3 benchmark while testing my FPS average at 1440p is around 222 FPS whereas a normal stream (using NVENC) the average bumps up to about 246 FPS, so a little over a 10% decrease in performance....

OBS Not Outputting the 6 Audio Tracks I have it set to output

I have older streams of mine where when I drag them into Premiere it has 6 different audio tracks with the specific source i gave in the Advanced Audio Properties tab (All audio on track 1, my mic on track 2, game audio track 3, etc). Im not sure what happened since then but I am unable to get this to work now. Right now im recording to mkv and remuxing to mp4, ive tried different video encoders but nothing seems to be working. Would anyone be able to help? Ill post some screen shots. The premiere one has a test video i just recorded in the beginning, and then an old stream i did after it for an example that it used to work. If anyone would be willing to hop into a chat or something to help out, id be all for it. got no other plans for the evening. Thanks!...
