VideoHW / RetroTink2x

"The RetroTINK-2X is a plug-and-play, ultra-low latency line doubler. Connect your retro-console over composite, S-Video and component to your modern display!"[1]

Overview

A RetroTink-2x is a desirable video line doubler due to the fact it supports composite and s-video sources. While most consoles are capable of producing RGB or YPbPr video, others may require modifications if available. Modern televisions may also not have any analog inputs which makes it an ideal companion for gaming.

The RT2X does not do optimal sampling. While this means other solutions can provide a sharper image, the ease of use makes up for the step down in video quality. Video output is generally clean due to 4x oversampling on inputs, outputting a 720x240x480 image.[2] More modern consoles such as the gamecube, ps2, xbox and wii output a native 720x480 and should result in a clean digitzation of the signal that should be about equal to optimized timings with other devices.

Another plus for the rt2x is the fact it handles resolution switching very quickly. Depending on your capture or display device you might not even drop sync when playing resolution changing games as shown below.

The device has some general limitations. It does not have native RGB inputs which may be a large issue to some users. However Mike Chi its developer sells a RGB2Comp which can be purchases here. Another limitation is the fact it cannot handle 480p sources. The chipset cannot handle 31khz sources and without major hardware revisions will not be able to support such video signals.

Video Capture Guidelines

You only have three outputs the device will produce. 240p,480i and 480p. The 240p and 480i are achievable via passthrough mode. If you are capturing interlaced footage using the passthrough to deinterlace with your own post processing is recommended. Otherwise the 480p output is a bob deinterlaced image. For maximum display compatibility 480p is advised.

According to the newest firmware notes[3] the output is now 4:4:4, older units were outputting 4:2:2. The update is supposed to also improve video quality across composite and s-video inputs
