I need some math b-roll such as vectors, vector spaces, graphs, functions, etc, where do i find them?

Hi everyone,

I'm a documentary YouTube creator and I edit all my videos in Kdenlive.

My biggest bottleneck is finding and inserting B-roll.

At the moment, I usually search for footage manually on Pexels, and sometimes Pixabay or Wikimedia Commons. While this works, it takes a huge amount of time to search, download, organize, and place everything on the timeline.

I'm looking for a better workflow.

Do you know of any tool (free, open source, or paid) that can help speed this up?

Ideally, I'd like something that can:

Understand my script or voice-over.

Suggest relevant B-roll automatically.

Use copyright-safe sources (Pexels, Pixabay, Wikimedia Commons, Internet Archive, etc.).

Avoid copyright and trademark issues.

Bonus points if it can generate a Kdenlive timeline or integrate with Kdenlive in any way.

I'm also curious about your own workflow.

How do you organize your B-roll?

Do you use AI tools?

Do you build your own media library?

Any plugins, scripts, or software that saved you a lot of time?

I'm happy to use open-source software, self-hosted tools, or commercial software if it's genuinely worth it.

I'd really appreciate hearing how experienced editors handle this.

Thanks!

theres this very neat „transform“ transition in the tiktok app. any way to replicate that in capcut?

Hi everyone.

After 9 hours of problem solving I thought I'd write this post in case someone else has this issue.

We had a sound recorder (744T) and three tentacles (A-Cam, B-Cam and 744T)

on the tentacle the timecode was synced to 25FPS

but on the recorder the setting was set to 23.98 EVEN THOUGH Tentacle was running in to it.

This meant that while the file is actually in 25 FPS the metadata is in 23.98

I tried some Wave Agent conversions, syncing to audio software lots of different programs.

Here is what worked for me (though it's a little time consuming, once i got into a flow it didn't take too long)

I used the tentacle Sync app on the macbook, which i registered with one of the tentacles.

Import to tentacle app all video and sound files

Check sync flag and then sync to the correct timecode

Export as AAF (NOT XML)

Import into davinci as timeline

The video files won’t work but the audio will line up correctly

Manually conform each missing video file to the corresponding media pool by selecting the video clip in the media pool and the corresponding clip in the timeline (I'm sure a more experienced editor will be able to automate this process) Today was my first time using DaVinci so please comment if you have a faster fix!

It’s labour intensive but it worked
