Does Aegisub not work with 4K video? Have a few 4K movies in MPEG-H/HEVC/H.265 (according to MKVToolNix) ripped from 4K BDs that I'm trying to add subtitles to. The error I get is:
An unexpected error has occurred. Please save your work and restart Aegisub.
Error Message: One or more characters could not be converted to the selected target encoding and the version of iconv Aegisub was built with does not have useful fallbacks. For best results, please build Aegisub using a recent version of GNI iconv.
If not, would I be able to create a temporary 1080 version of the video and edit/position subtitles, and then have it scale properly to the 4K video version?

I was also wondering whether ASS subs needed "upscaling" to 4K resolution. Since SUP on UHD-BD are authored in 1080p also.
I think it depends on the player how to act with it.
VLC displaying everything in muted gray colors instead of vibrant colors...
Overnight I used Handbrake to re-encode the video as H264 at the same resolution and it opened fine in Aegisub. I'm now be able to do my subtitles, and keep the fancy formatting and have it match the final full quality video in terms of subtitle size. I was worried about what you were saying, Ennio, so that's why I re-encoded to the full resolution instead of just downscaling it. I did the re-encode over night so time wasn't an issue in this case.
