Best Da Vinci Resolve export settings

[Zululander]

I have just got an Insta360 and am using it to create 4K clips that I then splice together in Da Vinci Resolve. I have uploaded a couple to JellyFin and they worked but I have now changed something somewhere and the new Videos that I now add do not play or generate thumbnails.

Here are the settings that I am using (I have also tried Format: MP4)

   

Both files played on my computer with VLC

I don't think it is related to the export settings here because it looks fine to me. If it does not play nor generate thumbnails you'd better give us the server logs and the ffmpeg logs

Just check my QNAP and the CPU is running at 100%. That would do it.

While typing this reply, video started buffering really badly. So there appear to be a hardware issue that I need to sort first.

It is just strange that the last two video that I uploaded were fine.

I am using a qnap VM and that probably can't cope with 4k video.

As long as the client doesn't need transcoding, 4K video isn't a problem for pretty much any device. A potato can send a file over the network. It's when your client needs transcoding that would require a more capable server.

Just built new server. Thumbnails now generated and video starts playing but it keeps buffering.

How do I know if the client needs transcoding and is it possible to prevent this?

[TheDreadPirate]

You don't really know unless you really study the advertised capabilities of the clients and know what media codecs you have.

The only way to really prevent transcoding is to have super capable clients (full PCs) or have super compatible media.

We'd have see your hardware specs and your logs to figure out why it is buffer.

Thanks for your help with this. That all makes sense

Just for completeness sake, I go things working using the bellow Da Vinci settings i.e. these seem to be such that me clients can process the videos.
