dvdsubs are RLE (run length encoded) bitmaps. It appears that when dvdsubs from SD are encoded into full-HD, the run lengths are 720-to-1920 scaled and the lines (for NTSC DVDs) are 480-to-1080 scaled. That's great. However, the character bodies in the resulting dvdsubs are very fat and overrun each other. I presume the overruns are because the spaces between letters are not also scaled. The resulting subtitles are still somewhat readable but difficult.
Does anyone know of a work around? Ideal would be scaling without 'fatness' by keeping letter stoke widths unchanged but scaling the heights and widths in addition to position -- yes, that will be tricky. Also ideal would be control over the palette. --Mark. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
