    First, A9LH gave us brick recovery without a hardmod, and now NTR gives us screen recording without a capture card. Is it Christmas already?! For those who are unfamiliar with the latest NTR release, the 3.4 preview enables users to wirelessly stream the N3DS screen to a PC, which can then be recorded via a screen recorder. From the initial NTR preview thread, there was a mix of different results with regards to video frame rate and streaming quality and it looks like several factors are at play.

    The purpose of this thread is to provide a dedicated place for people to post footage recorded from their 3DS streams to show the quality that can be recorded with the latest NTR CFW. Please also post the setup specs such as console NAND information, CFW used under NTR, NTR build (for future preview builds), software tested, router used, router specs, router congestion, and PC specs. This is so that we can get a better understanding of what can be achieved so far and to identify any possible bottlenecks or limitations that can be monitored to improve recording quality.

    Here's my example:


    (Warning: Contains spoilers or plot ending details)
    Console
    N3DS XL/A9LH/AuReiNAND 4.2/Updated sysNAND 10.7
    NTR CFW 3.4 preview version 1

    OS
    Windows 10 (virtual machine on OS X 10.11.4)

    Router
    TP-LINK D20 AC750
    3DS connected via 2.4GHz 802.11b/g
    PC connected via gigabit Ethernet

    Recording Software
    QuickTime 10.4

    Console
    N3DS XL/A9LH/AuReiNAND 4.2/Updated sysNAND 10.7
    NTR CFW 3.4 preview version 1

    OS
    Windows 10 (virtual machine on OS X 10.11.4)

    Router
    iPhone 6 acting as wireless router with MyWi 9
    iOS 9.0.2, 802.11a/b/g/n/ac, 2.4/5GHz dual band/300mbps maximum transfer rate
    No devices other than the PC and 3DS connected to the network, minimal congestion

    Recording Software
    QuickTime 10.4

    Software Tested
    - Home Menu
    - Majora's Mask 3D
    - Super Smash Bros. for Nintendo 3DS
    - Mario Kart 7
    - Resident Evil Revelations
    - Xenoblade Chronicles 3D
    - Attack on Titan: Humanity in Chains
    - Nintendogs and Cats

    So far I've noticed that the router used seems to be the biggest contributing factor, with old 802.11b/g 54mbps routers being unable to support proper streaming (either the bottom screen is completely missing from the stream or the entire stream is unable to sustain more than 3 frames before connection loss). Having dual band supposedly helps as it avoids interference with 2.4GHz from the 3DS* but I'm not sure how much of a contributing factor that is.

    I think your video example got hit by copyright ninjas. I'm blocked from viewing it.

    Turns out the music in Mario Kart was triggering YouTube's copyright filters and causing certain regional blocks. I'm in the process of removing the audio tracks... :(
    Actually it was a track from Attack on Titan being flagged by Pony Canyon. Oops.

    Would be cool if you can pm me, because I have a similar setup (iPhone 6s and want to buy MyWifi 9) For now with the normal Hotspot, it isn't working) Plus my 3DS is different than 192.168..... its 172.20.....

    Quick word of warning though, MyWi is quite unstable and has a tendency to drop connections and refuse to restart Wi-Fi hotspot until the phone is rebooted.

    I know, I'm familiar with that app, I got it in the past and worked well with it.

    iPhone 6s, iOS 9.0.2 here

    I really don't feel that good results can be produced from using phones as routers. I might test this when I get home. I have a MBP running 10.11.4, so I'd like to see how well it works with an actual dual-band router and Parallels.

    Damn canyon full of ponies is preventing me from watching the video. : (

    I thought the message was a joke until I looked up "Pony Canyon" and learned it is a real company.

    Update:
    Switched the video link to a version without the blocked content.
    Turns out two tracks were triggering YouTube's copyright system. The Nintendo track from Mario Kart was matched but wasn't the one causing the region blocks. It was the BGM from Attack on Titan. My bad.
    You're probably right, while phone-router footage is good enough to see what's happening on-screen, it's quite unstable and the frame rate isn't as good as some other footage I've seen. Still, it's better than the 14 year old router we have in the building, which stops working when we try to connect more than 3 devices to it.:P

    Here is my test result for Pokemon with the multi cheat plugin.
    Pokemon X,Y,OR,AS (USA): FAILED, black screen right after the title

    It seems having a cheat plugin even disables the network communication for NTR's Debugger and Screen Capture along with normal internet access.
    this does not happen immediately so the you have enough time to get to the menu before the connection is severed.

    I'm thinking of getting a TP-LINK D20, as our current router only supports 802.11b/g and can't handle more than 3 connected devices. Can someone experienced with wireless setup give me their opinion on whether or not this will support stable video streaming from the 3DS while still allowing other devices to operate normally on the network?

    Hows MHX or MH4U looking on stream? Seems like faster paced games (Mario Kart, DBZ) hold it back, and MHX is capped at 30FPS so I would assume that it would be alright. MH4U at 50ish (N3DS) Probably wouldnt run too great

    According to the information in the NTR wiki, you should enable debugger/video stream after starting the game if you're using ingame plugins.

    Playable is very subjective here, I tried Bravely Second and it was not what I would call pleasant to look at, it was very choppy and delayed compared to the 3DS screen. Certainly not good enough to upload to Twitch/YouTube.

    MHX is alright, but still unplayable from the screen because of a few lags here and there and a framerate stuck around 15-20fps. It is alright, still not quite there yet though.
