hi ill, I'm looking for a device to capture 1080p 60fps mp4 (h264) from my satellite... ive seen several devices that capture 1080p in 60p but I'm guessing that the actual capture software on the PC is responsible for the "Heavy lifting" of making the mp4 in real time? ive had bad experiences with such software that slows my PC down to a grind, and drops frames if I even try to load a browser at the same time.
Is there a capture device that does the h264 conversion inside the actual device, rather than in the PCs software? because that's what I would really want...

Maybe something like the Hauppauge Colossus or Hauppauge Colossus 2. And I'm going to assume that your satellite broadcasts are really 30i, which can be deinterlaced to 60p by your TV or computer.
hi Karma thank you for responding!
the Hauppauge Colossus 1 and 2 only capture at 1080 60i, not 1080 60p.
assuming the satt broadcasts in my country/area are really 30i would be wrong. Ive captured at 30i (and 60i for that matter) eg the ticker across the bottom of the news channel and the result is a far more jerky (30i) or blurry (60i) ticker than broadcast.
it really needs to be 60p i believe to look the same smoothness and sharpness...
any other suggestions? Hauppage make the HD PVR60 which captures at 1080 60p, but im not sure if the box does the h264 conversion or the software?
Bluray Videos support 1080p 60p, just 1080p 60i (really 59.94i) which comes out to 30 frames that are interlaced per second.
As far as progressive 60fps capturing devices, you might look into HDMI capture devices used for recording Xbox One and PS4 game play. But I don't know enough about that to recommend anything.
If the satellite receiver outputs 1080p60, then the following capture devices have built-in H.264 encoder chips and are able to capture 1080p60 as 1080p60:
AVerMedia Live Gamer Portable 2
AVerMedia Live Gamer Portable 2 Plus
Hauppauge HD PVR 60
Elgato HD60 PRO
I don't know if one of them is better or worse than the rest. All of the above capture audio as 2-channel AAC. All have limited options for capture software -- possibly only the software the manufacturer provides. None of them ignores HDCP, which the satellite receiver will certainly apply to HDMI output for copy protection, so you will need an HDCP stripper too.Ignore list: hello_hello, tried, TechLord
VU+, no need for recording with external device
Instead raw video capture elementary stream.
thank you usually that is what I was after!
do any of these units de-interlace on the fly as well? so if its really 30i then it de-interlaces to 60p?

Unless your satellite can actually give you 1080p 60fps good luck with that and do keep in mind you have to deal with HDCP carp
I have Sat (Dishnetwork) but no free channel open that do 1080p 60fps as there all VOD carp channel
None of them do de-interlace you going need high video scaler for that when come to 480i and 1080i
The best thing to do if you can is to setup the STB to output 720p which give you 60fps as well

ok it seems the satt outputs at HDMI 1080i50.
what if I used this new thing? The Blackmagic Updowncross HD...it says I can convert from 1080i50 to 1080p50....does it essentially de-interlace? or does it just drop frames? anyone know what kind of job it does?

Nobody support Realtime Deinterlace in hardware
First Gen HD-PVR and Colossus do not support 1080p at all
HD-PVR 2 and Colossus 2 support 1080p50p but it recorded as 1080p25
HD-PVR 60 support 1080p50p
You need look for Faroudja DCDi Processor, IDT HQV Vida Processor that are found on high end Video Processor Upscaler or A/V Receiver ask on AVSForum about deinterlace processor.
I told you this earlier, but you don't want a device that converts video from 1080i50 to 108025p. Deinterlacing 1080i50 to 1080p25 would require either throwing away half the fields (resulting in motion that is less smooth than the original) or blending the two fields in each frame together (resulting in combing artifacts) so neither option is desirable.
For programming which is televised live, such as sports, each field captures a unique moment in time, and when the video is deinterlaced, each field should become a progressive frame so that no picture information is lost. So, if the sat box outputs HDMI at 1080i50, and you want to deinterlace that output so there is no loss of picture information, you want a 1080p50 conversion.
The Blackmagic Updowncross HD is a video standards converter which is supposed to be able to convert 1080i50 input to 1080p50 output, but it outputs uncompressed video via HDMI or SDI. If you want an H.264 mp4 file, you will also need a capture device to encode the output of the Blackmagic Updowncross HD to H.264. The other problem is that the Blackmagic Updowncross HD appears to be for video only. How are you going to provide audio to the capture device?
[Edit] I think that the Blackmagic Updowncross HD provides audio after all. I missed this line in the Blackmagic Updowncross HD's product description: "automatic audio delay for perfect AV sync" I guess that means it passes through HDMI audio input with a slight delay to account for the video processing time so that the audio and video output remain in sync.

Blackmagic Design's product page for the Blackmagic Updowncross HD says the following:
Convert any SD and HD input to "720p50, 720p59.94, 720p60 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60
1080i50, 1080i59.94, 1080i60"

They don't list any kind video processor feature so unless you test one your self you don't know if really support Deinterlace form 1080i 29.79fps to 1080p 60fps or any of the other processor feature like Dotcrawl and so on.
When come to gaming this best for that is here http://retrogaming.hazard-city.de/

I don't know for certain, but I tend to doubt that the Blackmagic Updowncross HD has the ability to detect and remove duplicate frames or detect telecined content and use inverse telecining to produce progressive content.Ignore list: hello_hello, tried, TechLord
The Blackmagic company is based in Port Melbourne, Melbourne Australia. Its literally around the corner from me, about a 5 minute drive. This new box updowncross HD is a very new product. Theres no manual online that i could find for it. Im going to give them a phone call this week and see if i can get an answer out of them re:de-interlacing. ill post back with the result
i50 = 100 fields per second how i understand it.
Just like i25 = 50 fields per second.
read here: http://www.100fps.com/
"Do you think you record 25 frames per second when you make a movie with your digital camcorder?
Your digital camcorder does the following:
Records 50 pictures per second, intermixing every 2 consecutive pictures (with half the height) into 1 frame.
capture 25fps=50 fields per second"
so if capture interlaced 25fps = 50 fields, then it stands to reason that capture of interlaced i50 = also double = 100 fields surely?
As I wrote earlier, there are 2 systems for describing interlaced video. One system counts fields (i.e. 1080i50), and the other system counts frames (i.e. 1080i25). ...and I was not the only one who told you something like that. Look at what Karma wrote in post #4. Yes, it is confusing but 1080i25 and 1080i50 do mean the same thing

100fps.com hasn't been updated in ages, so much of it is inaccurate now, even though it was an interesting and helpful site earlier.
Most new cams these days, esp. Phones, record progressive (frames). Some cams have interlace options, but those are usually relgated to legacy formats, or to the very limit of their bandwidth capability (i.e. 1080i vs 720p).
Excepting action cams, scientific & pro cams, almost no cams shoot higher than 50/59.94/60 frames. Or fields, same numbers.
