Thanks, everyone, for reminding me about the DVD presets. Talk about use it or lose it - I lost that they’re in Shotcut.
I was able to get Shotcut to output a 1080 16:9 59.94 fps .vob but… there’s still far to much pixelation due to compression. The final product will be seen on a 50+" display. This resolution just doesn’t get it done. I get the DVD’s size limitation, and edited the video down to about 4 minutes. The video’s about 2.63 Gb or loosely half of the DVD size limit.
The .vob size limit is 1+ Gb per .vob and 4 or 5 sequential .vob’s can be present on a DVD-5 disc. Any Win10 authoring tool, as well as Shotcut, doesn’t seem to come anywhere near this. Why?
