Skydigital Supercast T3 2.0 HDMI Review


 The new capture device has released by skydigital in South Korea in May 2015 which can both record and live-streaming. While I didn't concerned about buying this company's products becaused of tons of bugs in past products I bought, fortunately my one of friend bought this product and I also looking for this one focusing to interesting feature, standalone live streaming, and I provided information by him. It may be insufficient review because of  I don't have this product, I'll introduce Skydigital T3 as exactly. I acknowledged to MBG provided about sample data and to PRETTY MAZE provided about some technical comment.

Specification

Input Resolution : 240p, 480i, 480p, 720p60, 1080i60, 1080p60
Recording Resolution : 480p30(if source is 240p or 480i), 480p60, 720p60, 1080p30(if source is 1080p60)
Streaming Resolution : 480p30, 720p30, 720p60 (Sorry for wrong information)
Bitrate : Maximum 20Mbps
Container : TS, MP4
Hardware encoder : Sigma Design PL330
Codec : H.264 High Profile 4.0, AAC-LC 128kbps ABR
Color : BT.601 YUV 420, 16-235 level
Mode : PC-live streaming/recording  mode, Standalone recording mode, Standalone live streaming mode
Directshow capable : No (Cannot be use on directshow-software)
Bypass Output : Only HDMI
- bypass HDMI-to-HDMI or automatically transcording Component-to-HDMI

 The key features are that it can be live-stream by itself, live-streaming by standalone mode. You can both record and live-stream simultaniously by Supercast T3, no longer needed PC. Obiously such portable device can live-stream to such major streaming site, ustream, twitch, youtube or custom CDN server, as standalone is only have professional devices that are over $600. The price of T3 is just ~$170 in Korea, you can found this feature in below list.

- Cerevo Liveshell Pro ~$600
- Matrox Monarch ~$1000
- Epiphan VGADVI broadcaster ~$1600

 These are for professional, not for consumer, too expansive for capturethe games to share everyone.
The disadvantage is only one thing that T3 has limited streaming resolution, up to 720p60 720p30 while the professionals are up to 1080p30. I think this problem is just never mind, affortable as price.

 Another feature is that it can be record/stream retro 240p resolution. Yes repeat, really 240p capable. I checked the recorded playstation 1 game "Raystorm" on playstation 2 via component output, can be mornitoring to play the game via HDMI, forced transcoded from component to HDMI output. You can check detail of this point in below resolution table.

 As I mentioned above, this is hardware encoding type device, it means not capable for open broadcaster software. Actually you can capture in OBS by screen capture that is not the point. Maybe skydigital would not be produce directshow driver like avermedia LGP stream engine.

- The 240p or 480i component input will be forced transcoded to 480p30, unable to processing bob 2x deinterlacing filter.

- Forced deinterlaced 480i to 480p30 (based on odd-frame)

- 640x480 60Hz : Recognized as 720x480p60 however, the horizon resolution has been compressed as 540x480. Blank has 90px each in left and right, while 720p record setting result is 960x720 that is not compressed. It means that the record setting should be set to 720p for 640x480.

- It is possible to capture composite signal, but only for luminescene signal (see Example 7 below this page.)

- Sometimes it grabbed even-frame confirmed by keyboardmania on playstation 2, in this result we couldn't conclude whether the problem is caused by T3 or not.

- Has not checked record/streaming stability, latency of bypass/transcoded output, video-audio timing latency, and still has not confirmed some resolutions, I will update soon.
 (Update) streaming stability test result : Twitch Tokyo server / 720p 3Mbps, 100Mbps FTTH
Depending on ISP stability
1st try : 17hour
2nd try : 2hour 8min
3rd try : 11hour 33min


- Depend on source output, T3 can be streaming as 720p60 720p30.

- No mic-input, you should make sure the mixing before capture.

- HDCP content cannot be capture, unlike past skydigital products.



A clone product...?
Actually I found altanative two products of USB2HDCAPS, REX-HDGCBOX2 that seems to be simillar product last 2 month ago in U.S. and Japan. Only different the case, definitely exactly same functional and compatible with bundle software each others even though there are selling different companys. I guess these products are just OEM product by K-world made in China.

  1. Do you happen to have a link for firmware or software for the Skydigital brand box?

    1. Hi AndrewG
      Sorry I cannot understand what you said, If you said about firmware/software link for Skydigital, here's the link the official download.

      http://skyok.co.kr/board/index.html?imode=view&D=4&c_id=206236&my_mode=&search_1=&search_2=&start=0

      I tried by this driver, but you'd better don't use this software.
      In my experience, Startech one should be stable than this.
