v0.9.4

The missing half of the DaVinci workflow. -davinci does two jobs, and only one of them had a button: taking a file apart was there, putting it back together was command line only. The Join page now offers both routes:

• 1:1 - everything copied unchanged, the way back from Split.
• Resolve-ready - audio DaVinci Resolve cannot read (AC3, E-AC3, DTS, TrueHD, Opus, Vorbis, FLAC, anything above 5.1 or above 48 kHz) is re-encoded to AAC, and subtitles are cleaned along the way. The picture is copied either way.

Files the list cannot use no longer vanish silently. Dropping a video together with its audio - exactly what you would try when looking for the join - used to make the audio disappear without a word, and the window then quietly split just the video. Those files now say so and point at the Join area. Dropping a whole folder stays quiet: other material next to the videos is normal there.

With this, everything NVENCForge.exe can do is reachable from the window.
