My guess is that the development on this program is pretty much finished, but the only thing holding me back from making a purchase is the lack of Video Export function which I had been using frequently in the “other” notation app… With all the sleek and modern features this app provides, it just seems like a big miss-out, especially in the age of social media.
There are no plans currently to add this in, correct…?
Welcome to the forum!
What makes you think so? Believe me, there is a plethora of requests that have been made here, and the dev team has a huge backlog. So a video export function like you described could be added to that long list - but regarding the limited time and resources of the dev team, we users will always have to respect their choices of what can be included in the next major version.
EDIT: I might add that the Dorico devs are the most responsive I’ve ever encountered and are closely monitoring this forum. (The only person I can think of that might come close to them is Geoff Fraizer from Blizzard in the old Warcraft III (original) days of my youth.)
Anyway, feel free to put forward your requests, but please be patient, as software development is an immensely complex task, especially if it’s for such a diverse user base as the likes of us.
The Development Team has shown themselves open to suggestions compatible with the nature of the program. At the same time, screen capture programs are available and reasonably priced, and I suspect more users would prefer to see features like audio import to video export at least in the immediate future.
At any rate, the development of Dorico is far from finished.
Eh? They’ve only just got started!
There remain large numbers of frequent requests in every area – notation, audio, video – cutaway scores, audio tracks, engraving improvements. The team have got plenty to add to future versions!
Can’t say I’m up with the latest trends, but I’m not sure that sharing video clips of scores playing back is what the kids are mostly doing.
Since a video is imported, and the audio can be exported, they can easily and better be synced and finished in a dedicated app like Final Cut. Why in the world would you want Dorico for that? If you have other audio tracks (e.g. voice or SFX) you can’t mix them in Dorico, you can’t do cuts, color grading, fx, transcoding and the like. Makes little sense to prioritize a feature that would have limited use.
Maybe @ojsa307o means automatic export of video of the score with a scrolling playhead along the notes? That’s definitely one of the as yet unfulfilled wishes.
Since to date the Development Team has not shown an inclination to add a scroll routine that keeps the cursor in the center, that’s where screen capture of the page-at-a-time display may have to suffice.
Nevertheless, one can always ask, but it can be done without suggesting that Dorico is no longer being improved, which is a silly misconception.
Wouldn’t it be fair to wait for @ojsa307o 's reaction first? Just don’t wanna scare off anyone based on their first post.
Perhaps, but it’s a god-send for choir directors who’s members often do additional learning from home. My little YT channel is creeping ever closer to 3k subscribers. It’s strictly animated score videos of church music. Make of that what you will. 
Very polished, handmade animated score videos with human-recorded audio. That’s a long way from a direct screen-grab with computer playback.
I appreciate the comment. (And I agree) but having the animation done for me, even if I did then overlay my own audio, would still be a not-unwelcome addition. In any event, I don’t begrudge people wanting an easy way to get their music out there quickly in the hopes of catching at least a little wind in their social media sails. Admittedly, even for me, this is very low on my priority list.
That very Team designed that feature in Sibelius and I think I remember they were not too keen on doing that with Dorico because of copyright issues that could emerge (from their former beloved company…)
So this is clearly not a bad request, it’s been already asked for a number of times, and the wise thing to do is look for a solution involving a third party app. 
Actually there are a lot of composers doing it all across YouTube and social media. It’s becoming an increasingly common way to share one’s scoring portfolio. There’s even websites devoted to the task of creating them. https://scorefol.io
MuseScore doesn’t have such a feature as creating videos but they do have a way to publish scores digitally to the internet for sharing, which are somewhat interactive and similar to a video in that they exist in a player with a scrolling playhead etc.
My point being the future of sharing scores is definitely moving toward the digital and internet domain, so there will be a demand for it with the kids soon enough!
I agree though that this is probably on the lower priority compared to everything else the Dorico team has to do, especially regarding professional music engraving and production, and at least for the time being is best left to third-party apps. Perhaps that website above will be helpful to some!
Interesting. I’ve never heard of this. TBH, I’m not sure that it is substantially easier than just creating graphic slices and animating them by hand anyway. Parts of the workflow are nice (white boxes to hide unintended markings from half-cropped items, and automatically extending a graphic (time-wise) until the next image is inserted) but really it doesn’t offer a ton over a normal video editor.
I’ve not personally used it (I have my own preferred method using PDFs into After Effects so I have no need for such a tool), but I mentioned it because its existence is evidence of a market demand—although still a rather niche market—but there are people using it and when I trawl YouTube it seems there are lots of people looking for an easy/automated way to create score videos with limited or no technical experience.
Indeed.
You can create videos with musescore: https://youtu.be/rLNA21O13i4?si=NoN170Q1kMRQ7xs9
They are quite ugly videos, but yes, it is possible.
