Best video format, codec and all parameters for dtube ? ? ? ?

Hello, I want to ask of you guys about tube and video uploading.

I made some videos and for a while I’ve been trying to upload, I’ve been watching videos, reading posts, but it’s not really helping.

Maybe some of you can shortly write in comments exactly what codec, format and others parameters you using and what’s is best working for you :)

I’m editing and exporting videos with “Shotcut”.

Thank you very much!!
