That device isn't an extender.
No wonder it is expensive. It appears to compress the HDMI output from a set-top box to H.264 in order to stream it over your wiring, decompressing the video at the other end for HDMI output. Using Home Plug networking may interfere with it.

I have the Elgato Game Capture HD 1.42.9.524 (latest version). I'm recording a TV programme which is at least 2 hours long and 20GB in size. Isn't there any way to record to a single .ts file without the software breaking up the recordings into several .ts files? The HD PVR doesn't split the files so why does the Elgato?
I know I can choose the "always convert newly recorded videos" to MP4 (muxes) to get a single file but I can't do that as the software always crashes about half way through saving it.
My only option is to use the joiner in VideoRedo to combine the TS files into 1 file however for some reason it always gives 64 Kbps AAC instead of the original 224 Kbps AAC. Seems like a strange bug as VideoRedo usually just muxes and doesn't re-encode the audio.
I could use TSMuxer but it's a bit fiddly as you have to drag the files one by one into the window (mistakes could be made if you drag them in the wrong order). Is there anything else that's simple to use that can mux several files together? -
Apparently the output for the Elgato Game Capture HD is always split into 4GB .ts files and there is no way to change what it does and no alternative Windows software for it. See https://forum.videohelp.com/threads/360514-Game-Capture-HD-program-keeps-splitting-up-recordings.
I would have suggested what you already tried for joining the files, so I'm no help there. -
Are there still no HDMI capture devices like the Elgato Game Capture HD that can record in AC3 besides the HD PVR which is buggy? Just looking for something reliable. Even the Elgato has glitches where there could be several video frames missing in a recorded video however the source did NOT have that problem. I've also seen it fade out to black then fade in again at the start of the recording several seconds into the recording which is odd.
I thought that the point of using an external capture device like the Elgato was that IT did the processing and not my PC so I wouldn't get freezing issues, etc. Even so I've got an 8 core 4.5 Ghz CPU and I'm still getting those issues.
I've got an 8 core 4.5 Ghz CPU. -
You miss the HD-PVR 2, HD-PVR GS Plus and Colossus they also can record AC3 as well
There can be any of a number reason why that happing must common cause are the Device it self is bad or USB port or some System Driver and let for Cables or could even be you System Motherboard Hardware even Overclocking or other Software can cause issues as well not counting the in coming source just because you can't see a miss frames in LiveTV Mode doesn't always mean it not happing.
You mean to tell me that Elgato Game Capture HD split it files into 4GB chunks that not a good idea even Hauppauge got a way from that because it causes more hum then good even now I'm beta test new Rocket firmware which did that at 2GB chunks but soon will no longer do that like with MPEG file back in old days and only one Editor could even deal with those multiple spans files or multi segment file it just to bad there not supporting H264 editing know as Womble MPEG-VCR or MPEG Video Wizard DVD.Last edited by SHS; 19th May 2014 at 09:06.

I'm aware of all the HD PVR models, they all have the same problems with regards to glitches and the encoder used is quite bad. Internal Capture cards are useless as you just get more problems as it's using your PC to do the encoding rather than using an external capture device.

Made a update to my post
I don't know about that after been running a SageTV for 10+ years with multi-tuners up 6 at one time with min diff Hauppauge Capture device both USB and PCI, PCIe.
What glitches are you ref to?.
Hmm what do you mean by there are more problem with internal capture vs external capture device.Last edited by SHS; 19th May 2014 at 20:17.

I don't know what is causing your dropped frames, and I can't tell you what HD capture device is going to work perfectly for you every time. There are no perfect HD capture devices that I'm aware of.
There are at least two internal cards that hardware encode. The Hauppauge Colossus and AVerMedia Live Gamer HD both use hardware encoding. The AVerMedia Live Gamer HD is supposed to have a maximum bit rate of 60,000 kbps and records 1080p30, but it is new enough that AVerMedia is still working out the bugs. It won't record interlaced standard definition input, and all recordings are converted to progressive even if the source was interlaced. The Hauppauge Colossus has a lower maximum bit rate (20,000 kbps), but it is less buggy since it has been out for a few years, and it records all normal TV resolutions up to 1080i, plus there are a few third-party PVR and capture programs available that support it.Last edited by usually_quiet; 19th May 2014 at 10:53.

The reason all the hardware manufacturers are avoiding having AC3 encoders is because Dolby charges a comparatively large amount for them to be included on these types of devices. They charge as though these are rack mount broadcast equipment, rather than small home enthusiast devices.
Devices like the HDPVR2 work around this by supporting passthrough of AC3 audio. ie, if it's supplied an already encoded AC3 audio stream, it'll include it as-is, without needing to re-encode. -
I would like to buy a laptop just for the purpose of recording from my Elgato Game Capture HD because I don't want to record with my PC while I'm encoding videos at 100% CPU usage as it may cause lag, etc. The min requirements for the Elgato are this:
Windows 7, Windows 8 or later
• 2.0 Ghz (or higher) dual core CPU, or 2.0 Ghz (or higher) multi-core i3, i5 or i7 CPU
• 4GB Total Installed RAM (or higher)
Can anyone who records from a laptop verify that they can record OK without issues by using a laptop with similar specs to the above? -
Only your PC my friend. Only your PC...
I have 4 PCI-e cards: 2 Aver C027, 1 Aver C985 and 1 Aver M799. Never trouble or issue in 4 years.
My old C2D E6600 recording 1080i with 0 frames lost.
My I5 use 5%~15% resource on C985. If C027 30%~45% lossless record.
Fixed your PC = Nice records. -

He's not encoding video. The Elgato Game Capture HD is a hardware h.264 encoder. But its software is very CPU hungry (about 25 percent usage on my i3 4130T, at least on Windows, I don't know about the Mac). I believe this is because the driver decompress the video for display with the CPU. Even when you're using their software to edit previously captured video, the driver is still decompressing the incoming video in the background. You might think you could use a filter graph to write the compressed A/V stream to a file without displaying it (like you can with the Happuge HD PVR series) but you can't. The driver only outputs uncompressed video! They must be using a direct connection to the USB port to get the compressed A/V stream.
I suspect these problems are because El Gato is basically a Mac company. They just don't know enough (or care enough) about Windows to write proper software for it. -
I am well aware that the Elgato Game Capture HD uses hardware encoding and that the drivers and software work in a very peculiar fashion because I have read your posts in other threads detailing your various issues with the device. I even linked to one of those threads in this thread.
However, the OP wrote "I would like to buy a laptop just for the purpose of recording from my Elgato Game Capture HD because I don't want to record with my PC while I'm encoding videos at 100% CPU usage as it may cause lag, etc. " So I took that to mean he may sometimes be encoding another video file while capturing with the Elgato Game Capture HD because he's been told that capturing with a device that hardware encodes requires few system resources and so he figured that he could use the computer to perform any other task he wishes at the same time he's capturing video.Last edited by usually_quiet; 20th May 2014 at 13:21.

This where the Hauppauge HD-PVR Rocket coming in to play usually_quiet No need for a Laptop or PC nor any Software and it works any OS any device that has HDMI output so long it not outputting HDCP.
Too bad the AVerMedia has a lot problem with there software/device as the Game Capture HD II has some better features ON paper but from I hear it not very good that was before AVerMedia close there forum and lock down there facebook page as gen post.Last edited by SHS; 20th May 2014 at 23:36.

The PVR Rocket is garbage. I bought that before I got the Elgato. It's buggy and the encoder isn't very good. I tried capturing HD TV at 8 Mbps and the quality was rubbish compared to the same bitrate on the Elgato. I don't know for sure but I imagine the HD PVR 2 is the same as I had the original HD PVR 1 component model and the same happened on that.

People who want the best possible HD captures use an internal capture device that uses software to encode so they can capture using a lossless video codec (UT Video or HuffYUV) and re-encode later using a good software encoder like x264 or HCEnc. The initial capture files are very large and since re-encoding is necessary, this method is less convenient, and can require more system resources than using hardware encoding.
People who want convenience choose HD capture devices that hardware encode and learn to live with less than perfect video.
So, you have a choice between HD capture perfection, and HD capture convenience. You can't have both at once with the hardware available today. Glitchy hardware or software can be a problem with either choice, and a second SATA-connected hard drive should be used for recording captures regardless.Last edited by usually_quiet; 21st May 2014 at 10:51.

I don't want uncompressed video or lossless as the file sizes would be massive so it's not practical. The Elgato is fine with regards to picture quality, the problem is that I get about 30 video frames missing in my Elgato recordings out of a 2 hour 15 minute video. Not sure why it's happening. I played back the source on my satellite box and it didn't have missing frames. I've already got Windows installed on a SSD and I do any video editing and Elgato saving on a non-SSD Sata III hard drive. Is that OK?
I've now bought a quad core 2.16 Ghz (2.40 Turbo overclocked mode) laptop just for using the Elgato on. I realize a laptop CPU is slower than a desktop CPU of the same speed however I read some reviews for the Elgato and they said a 2Ghz Dual Core worked fine for them. I won't be using it for anything else. Do I still need a 2nd hard drive for my laptop to use for recording Elgato videos on?
If so, I'm not sure how to install a hard drive into a laptop, I've built my own PC's but I've never messed with a laptop before. Is it easy to do? -
Generally, take the back of laptop and you should see hard drive.
Some have access cover separate from whole back cover.
Supposing your laptop has an optic drive, should be able to find caddy for adding 2nd drive.
Others can verify if an usb drive would be fast enough or not. -
A SATA III hard drive is fine for capturing the output of a card that hardware encodes.
Are the frames missing in the middle of the Elgato's .ts file or at the beginning and end of a .ts file? The Elgato Game Capture HD is always going to miss a few frames in the time it takes to close an old 4GB .ts file and open a new one. That is an unavoidable consequence of creating segmented recordings. -
The missing frames don't happen in the points where a video segment starts/ends. TSmuxer or VideoRedo is flawless in joining the segments so there's no pixellation, etc at the join points.
The missing frames just seem to be in random places like 6 minutes into the recording for example. I make sure I start/end recording 3 minutes before and after the start/end of the video I actually want to record to avoid the freezing issue that happens in the first minute of recording. -
-
If your system is too busy doing something else, especially something that involves using the same hard drive you are capturing to, that can cause dropped frames. ..or maybe there is a problem with the USB connection.
If using the laptop to capture eliminates the problem, it would certainly indicate that the root of problem lies somewhere other than with the Elgato device or its software. -
I just did a 3 hour cap on the HDPVR 2 with AC-3 sound from the HDMI in on my Asus i5 with a powered WD 2TB external hard drive with 0 frame drops at 14 Mbps so there is definitely something wrong with his capture setup.

I bought a quad core 2.16 Ghz (2.40 Turbo overclocked mode) laptop just for using the Elgato on. The recordings had lots of glitches where the picture would jump out every several seconds or so on certain sections of the video.
I then bought the HD PVR 2 Gaming Edition Plus for using on my desktop PC. Recording in 14 Mbps I noticed that it actually uses a variable bitrate regardless of whether you set Constant or Variable bitrate. Not bothered about that. Recorded two same pieces of video on the HD PVR 2 and Elgato Game Catpure HD at same 14 Mbps bitrate (tennis match). Both use a variable bitrate and the resulting file size was similar. The PVR picture quality wasn't as good as the Elgato and it had obvious artifacts. Even worse was that certain portions of the video such as background walls had pixellation yet the Elgato did not. Also the PVR did not record in the same colours that the source was in and changed the orange court of the tennis match into a pinkish colour.
So I'm now using the Elgato again and I bought a Core i3 Dual Core 3.4 Ghz Desktop PC (seen by Windows as a quad core) just for the purpose of using the Elgato on. I don't get any glitches like I did on the laptop but I still get dropped frames on some recordings. Recorded 3 hour F1 race and a few other 1-2 hour shows and didn't get any dropped frames. But on another 3 hour recording I got 66 dropped frames. Tried the latest 1.42.9 software and the 1.43.25 Beta software and it made no difference.
I save the recording in VideoRedo then I look at the log searching for "sync" to find the "frames removed" timeframes.
Can anyone recommend a capture device that has a good picture quality like the Elgato but which doesn't drop frames? I will even consider using a capture card inside my PC.
Also, I suppose I could try installing an SSD into my PC and try to record Elgato videos onto that to see if it solves the dropped frames issue. However there's a problem with my SSD, I was formatting it then I cancelled the format while in the middle of the format. Now it's not seen by Windows. Even if I format it in Disk Management - it appears in Windows Explorer but when I restart my PC it's gone. Is there a program I can use to format the drive correctly to get Windows to see it? -

I've been able to play with both recently and I'd have to agree that the the Elgato delivers better image quality. Though, when comparing frame by frame you'll find some look better in one, some look better in the other. I think Elgato applies a noise filter before encoding (losing some sharpeness and some small, low contrast detail) whereas the PVR2 (usually) loses those details (and more) at the encoder level. I've been comparing the two devices at 8 Mb/s and 15 Mb/s CBR. Of course, the El Gato can go up to 30 Mb/s.
The PVR2 delivers a lot more interlace comb-like artifacts. Even on progressive frames you can see alternating scan lines have slightly different brightness/color. Because the interlaced quantization resulted slightly different values).
The PVR2 records with rec.601 color without flagging it as such. Most editors and media players will assume HD video is rec.701 when the color isn't flagged. The default proc amp settings on the PVR2 are slightly off too, levels and colors need to be adjusted*. The Elgato's defaults give near perfect rec.709 color and levels.
If you're going to reencode the PVR2 caps you can always convert to rec.709 colors. For example, in AviSynth you can use: ColorMatrix(mode="Rec.601->Rec.709").
The Elgato does drop frames pretty consistently.
I don't think the dropped frames are happening at the PC (assuming the PC is fast enough). I think they're dropped by the device, the PC never sees them.
The PVR2 shifts the frame up by one scan line (recording 1080i). The Elgato shifts the frame up by two scan lines (1080i again).
What I do like about the PVR2 is the record button on the device and the low CPU usage (when not displaying the video). It can record on the same computer that's playing the video simply by pressing the button. You don't have to manually switch to the recording application, start the recording, then switch back to the video. You can just press the record button to start the recording, then press it again to stop. The recording app is also smart enough not to pop to the foreground when its started/stopped with the button.
* The PVR2 proc amp settings I used to capture 1080i30 from the HDMI input:
Code:Brightness: 15 Contrast: 58 Saturation: 60 Hue: 50
