There are other tools that will show you how to process all videos in a project, rather than a selected video. video from images is one that uses ffmpeg too.
Thanks RobM - that is very helpful.
Can you give us a (small) sample video that includes metadata using your own "standard?" And what's the field called?
Here is one. As indicated in earlier posts I am planning to use the XMP-exif:DateTimeOriginal tag for storing the local creation date (in this sample there is a 2 hour difference compared to CreateDate). I'm not wedded to this though - any other appropriate field would be OK so long as it isn't intended to store something different.
Then, even if ME can pull that field, what will jAlbum do with it? The jAlbum core isn't open-source, so you wouldn't be able, for example, to modify jAlbum to use that xmp field as the originalDate variable (for sorting album objects). And asking David to modify the core to accommodate a home-brewed metadata field would be a bit much.
Aww crap! I just assumed that as there are ao.setTitle() and ao.setComment() functions, there would also be an ao.setOriginalDate() function. Just checked the api and there isn't. As you no doubt already knew.
Scope vrs = ao.getVars();
vrs.put("originalDate", "10 Nov 2020 20:20");
but that didn't do anything useful either.)
Back to the drawing board.
Just about to go on holiday so I will mull this over for the next couple of weeks. Be nice if I knew what I was doing.
Just a flippant thought for an embedded date/time that will always be available as long as the video can be played, add a few seconds of an intro image showing the date, time, location or whatever to the video,
