Does anyone have any good tutorials for panning with orchestral elements? I cant find anything for trailer music for some reason..

Hi, everyone. A question for those who work for music libraries. What amount of LUFS do trailer libraries require? Streaming services ask for -14-12, just like YouTube, but analyzing tracks on Extreme Music, for example, you can see that they're mostly -8-6 and sometimes even higher. Do libraries have any volume requirements?

I was planning on doing some social media shorts where I post videos and add my own written music to the video and been messing around with Grok video generation but the videos are limited to 5 seconds, even with the paid X.com $8 subscription. Does anyone know if getting the higher tier subscription (SuperGrok I think it's called) raises the duration of videos? I tried to make a longer scene, basically telling Grok to use the last frame from a video for the first frame in the next video generation and to make it a seamless and smooth transition, and then stitching together the 5 second videos into a longer one (with ffmpeg command line tool... lol I'm old school) ... but this method isn't ideal because the video stutters every 5 seconds. I don't know if it's a limitation of the tool I'm using (ffmpeg) and need to get an actual video editor or if it's a limitation of trying to glue videos together in this manner. Any way to fix this? Are there other video generation AI that can create longer videos? I'm guessing I have to pay...is there any free ones or are the free ones also limited to 5 seconds? I like Grok because I use it daily to research things, and the image/video realism looks fantastic. I get it that these things are still new and in active development, but the 5 second limitation is a real vibe killer and so far my attempts to work around it have failed. If I gotta pay I might just have to, but it would be nice if there is a free tier that I can mess around with first, but it's not necessary. Anyone know any good ones or what would you recommend/use?
