Question / Help Opinions on the AVerMedia Game Broadcaster HD? (C127)

So first let me start off by saying I have an Elgato HD, and I've had nothing but audio syncing issues with it since the day I bought it. Occasionally it works, other times it doesn't and in all honesty so far it's been a nightmare.

Okay now that that has been said, I have a chance to get my hands on a C127 and I wanted to know about the compatibility and general opinions related to this capture card. I stream on Twitch, so that will be the main purpose of this device. My main goal is 720p/30fps streaming. The Elgato works, but the audio issues drive me insane and I'm getting sick of them.

Does anyone have any complaints about the C127 while using OBS to stream to Twitch? All I want is a device that works when I want to stream. Not something I have to fight with for hours on end to get to work correctly.

Has anyone had any issues with the C127 and OBS for streaming? Audio issues, video issues, anything that I should know about? I just want to install it, configure it in OBS and then stream. Something that the Elgato seems to be unable to do without either audio issues or some other seemingly random issues.

TL;DR Is the C127 a good card for OBS and Twitch streaming? Opinions?
 
I use it for several years now and love it. Upgraded from an h727 back then to be able to input 1080p60 footage and record it at 30fps. It also to my knowledge has slightly better visual results when it comes to colors, compared to the live gamer hd, the live gamer has the option to stream or record at 720p60 though (if you input 1080p60 footage) which is a nice thing, but nowadays you could think about getting a 1080p60 capable capture card if you want to do that.
Overall its a good device I would say. No delay problems and audio over hdmi works as well.
 
The C127 should be able to take a 1080p/60 input and then downscale to 720p/60 for streaming, correct? I can't just record or stream at 1080p/30, only 1080p/30 with the C127 I believe.

I'm honestly just fed up with my Elgato and want to try something else that has been a bit more well known. I know the C127 is old, but I don't want to spend hundreds of dollars on a Micomsoft card and then end up with some elaborate setup. I just want a card that can take HDMI video, and HDMI audio at the same time and stream them while they stay in sync with each other. The audio drifting out of sync with the Elgato is getting on my last nerve, no matter how many settings I try.

I have a AMD based system, I don't think that will make much of a difference with the C127 though will it? I know the X-Capture card requires a specific USB 3.0 chipset, or PCI USB card to function properly. I haven't seen anything like that related to the C127.

My main goal is to just find a highly supported, plug and play solution that won't cause me a million headaches. I thought the Elgato was it, it's not. I have also heard the same thing about the colors with the C127 compared to C985. The color red always looks blurred in most streams I see using the Elgato, including mine. From what I have seen on YouTube test footage, the C127 seems to do a lot better job at capturing that color spectrum.
 
As mentioned, you cannot downscale to 720p60, only 30fps works if you input 1080p60 material (only the live gamer hd can do that). You could input 720p60 material for a 720p60 stream/recording.
 
Sorry I worded that incorrectly, that's my fault. What I meant is that for example, If I am playing a game at 1080p/60 such as Resident Evil Revelations 2. My PS4 outputs at 1080p/60, I SHOULD be able to capture and stream that at 720p/30 without issue. I understand that capture card does not capture at 60fps for 1080p sources. It should however capture at 60fps for 720p and under sources. That should be identical to the Elgato HD, the non HD60 model. I just wanted to clarify, my mistake for wording that really weirdly.
 
Hey Jack0r, I received my C127 today and installed it. 720p capture seems fine, but I'm getting an issue with 1080p and I was wondering if you ever found a fix?

In this review, this person mentions the issue I am having. His "fix" works, but I would really prefer a permanent fix if one has ever been found.

The only problem is that when you first turn on something that is already plugged in to the unit, there is a 2 second audio delay (but video is fine). This can be fixed by simply unplugging the hdmi cable and plugging it back in. While this is a slightly annoying issue, it's not that big of a deal since it's easy to fix.

I also found another report of the same issue on a newegg review.

Did you ever find a good method to get 1080p to work well on this device?
 
Hmm, I would definitely recommend to use the latest driver off the avermedia page.
I havent heard of this exact problem yet and did not encounter it myself so far.

If I understand correctly, if something is plugged in before you turn on your recording pc for example, and then start the device in OBS, you get the mentioned audio delay? And if you unplug and replug its gone?
 
I have the latest drivers from the website, as far as I am aware newer drivers than what I have installed don't exist.

The issue happens when you are using a 1080p source. I never turn off my "recording pc" and I can trigger the issue repeatedly. If I use a 720p source, I have no issues that I can tell. Basically though, if you have OBS on, and you set the card to 1080p for a 1080p source. Then start the device, let's say my PS4 for example. OBS seems to be working fine, then if you playback the recorded video, or watch the past broadcast on Twitch. The audio has a delay to it, about 2 seconds it seems.

If you unplug the HDMI cable from the capture card though while the audio is in "delay mode" for lack of a term. Then reconnect it, the delay is gone. I have also been able to get this to happen using my PS3 through HDMI as well. If I have the PS3 set to native 1080p, set the capture card to 1080p it will have audio lag. If I start a PS3 game that is native 720p, and set the card to 720p, the lag won't be there. However, if I start a game that is native 1080p while the PS3 is set to 1080p native, the lag begins.

I also notice OBS detects a PAL resolution for some reason. I have to click "custom resolution" and set the device to 1280x720 or 1920x1080 manually. It won't auto detect in OBS like it does in RECentral. I also can't "force" a resolution in OBS. If I set the card to 720p and then use a 1080p source, the video is all messed up. The card has to be set manually to the source resolution to get any clear video from it.
 
Let me start at the end:
OBS to my knowledge reads the settings from the device, so its more the CaptureCard telling OBS to use PAL and OBS can tell it to use NTSC or whatever else is available on the device.
I also have to configure the custom resolution and framerate. It has to be configured to your Source resolution. So its normal that it wont work if you choose 720p but input 1080p.

I have a few ideas to work around that audio delay problem:
  • If the delay is constant you could in theory just activate use buffering on your source, start with testing 2000 (ms) and then in the audio section audio sync offset to -2000.
  • You could test if a hdmi splitter or hdmi switch could trick the CC into thinking it already had a source to get rid of the delay.
  • You could test if de-activating, activating the device in OBS helps, it should not be a global source in this case.
I really wonder why I havent heard of this problem before.
 
The audio delay is only consistent with 1080p sources, 720p sources do not have the issue. Setting up buffering would then interfere with 720p, and be more troublesome I think than just disconnecting and reconnecting the HDMI cable to temporarily fix the issue.

I already use an HDMI splitter, however that doesn't seem to make a difference or be the cause of the problem. I have the delay with or without the splitter for 1080p sources.

The device is set as a global device in OBS as it should be. Deactivating it doesn't change the audio sync, but it WILL cause the audio desync to come back if I had previously reconnected the HDMI to fix the issue while the original device is still on.

This audio issue is also present outside of OBS within RECentral as well, so I don't believe it's an OBS issue.
