It would be nice if we could set a cross fade between highlight clips for volume, picture or both. As in, clips played in a sequence would be less jarring when played in a sitting. Maybe 2 seconds of cross-fading where the volume from one clip turns down quickly and the next one comes up, picture fades in and out in that same period of time... something like that.

Volume and Picture "cross fade" between highlight clips

I agree that this would be nice. However, consider the technical requirements to implement this:
#3 is impossible with current hardware for certain audio formats, and you'd also lose any spatial audio (Dolby Atmos, DTS:X) features.
- You'd have to be simultaneously decoding two video streams at full resolution (in order to fade between them)
- You'd have to be able to composite the two streams together with variable alpha channel
- You'd have to decode the audio of both clips and mix them together, then output as multichannel PCM or re-encode into a bitstream format.

The fade-out -> fade-in idea could be possible tho, with no mixing or cross-fading?
This would be a huge feature for those of us building CEDIA demo playlists.
Another thing we’d love is the ability to bring down overall audio output gain to level-match from clip-to-clip. Most are fine but occasionally there’s one like John Mayer Where the Light Is that’s noticeably louder than most content on the store. Can be jarring or downright painful at demo levels.
Fade out would be possible for video, but not really possible for audio for any bitstream format, because we'd have to decode, do a volume transformation, then re-encode, and that's just not possible on current hardware. Same thing with level-matching.
Wait- how about simply decrease the volume from audible down to zero, starting 2 seconds before the clip ends, and then bring up the volume of the next clip from zero to the set level over the first two seconds of the next clip? I mean, I guess fading is the wrong term- I don't care if they are cross-faded together, I just want the audio change to be less jarring. Same thing with video- fade to black in the last 2 seconds of each clip, fade up from black in the first 2 seconds of the next clip...
