Question / Help 30 or 60 fps for a retro game?

Flamecookie · Feb 6, 2014

Hi, i've tested streaming a retro game from a dazzle and i'm not sure what kind of resolution and fps i should have. When i watch my own stream from another computer i can see that the stream is kinda shaky and not really fluid, but when i watch the archived video on twitch it looks fine. I have 5 mbps upload speed, and 720x480 resolution with 60fps, also 2000 bitrate. here is my log:

You unfortunately don't mention what console it is you're streaming games from, or what deinterlacing method you're using, making it a bit hard to troubleshoot this. If you are using retro deinterlacing, please be aware that it's only intended to be used with low resolution games (240p) such as NES, Megadrive, SNES, PS1, etc., not things like PlayStation 2 or GameCube.

If you are streaming a low resolution game and it looks shaky, this is probably because the Flash player can't properly maintain 60 frames per seconds in most cases, if you attempt to play it back using something like LiveStreamer, it will most likely look fine.

I see, i'm recording a SNES with OBS's retro/scandoubling deinterlacing. Ill try with 30 fps instead.

Question / Help 30 or 60 fps for a retro game?
