NuwandaIn the future, retro-looking videos will have compression artifacts instead of film grain.
They could. But why wouldn’t they just actually compress the video?
In digital/streaming video, there is no physical tape which produces grain, so there is no choice but to add it in post. But if you’re serving up digital video, then you can simply just serve up an authentic compression/bitrate/resolution.
I suppose maybe players in the future won’t support the codecs we use today?
r00tyI mean you'll always be able to. In the same way you could use actual VHS recorders or film to get those effects. But it's far easier to apply the filters. Likely yes, such codecs won't be readily available and it might be more effort to do the real thing than add a filter. Who knows.
