How could Genesis RGB look better than composite with the best encoder?

I saw some screenshot comparisons, and the compression from not using RGB is the only lossy compression I can appreciate unless the guy was doing it wrong. Isn't RGB always supposed to look super sharp compared to composite?

I think that Super NES composite on an old RCA ColorTrack I had looked better than any filter for BSNES (although I love BSNES and it's really better than playing on a Super NES anyway). BSNES is closer to RGB I imagine.

Exodus is a Genesis replicator (i.e., all processors are cycle accurate) and it's excellent (other than that it doesn't have any filters that mimic the composite with the first Sony encoder 1145 I think). Like BSNES, it's closer to RGB since nothing is being lost in an emulator. The guy who did Exodus is really cool, I think he's going to make a Dreamcast replicator... I'd love to see the Sega CD and 32X replicated with the Genesis in Exodus because Kega Fusion isn't all that good with games on either.

He was also talking about a Sega Saturn replicator (other than you won't have the beautiful looking first model console right in front of you). That's really now more possible than ever before, not only because of Haswell's AVX2, but also because of GCN and GK110.

The Dreamcast and Gamecube looked awful in progressive scan IMO mainly because of the low precision color buffer and because of aliasing secondarily.

Encoder doesn't matter with RGB.

I run all my 480p and ealier consoles through RGB or component (GameCube) on a Sony PVM-20M4U and wouldn't have it any other way.

For Genesis I have my model 1 "High Definition Graphics" non TMSS unit and model 1 Sega CD for the audio quality. Mix cable pulling stereo from the Genesis headphone jack and the Sega CD audio out going direct to the Klipsch 2.1. No only is the synth and pre amp and mixer hardware in that model the best of all Genesis models, but I also avoid the 60 Hz hum that affects RGB SCART cables. Audio vastly better than my model 2 setup regardless of pulling audio from the SCART or Sega CD line out, but RGB output is naturally no different.

RGB needs to be seen on a high end RGB CRT with a native 15khz analog source to be appreciated. Emulators and scaling and filtering and all that defeat the purpose.

RGB mods can be really hard to do right and the resulting image can suffer greatly. Probably needs an RGB amp or something.

RGB is superior in real analog hardware and must be seen to be believed.

If we are taking emulators, filters, scalers, framebuffers, post processing, sampling, etc there's no point in even worrying or talking about it. Everything is out the window once we are talking about emulation and pure software manipulation of digital data.
