Hello,
How to export a video with track differents quality video like HD, full HD, 4k and etc on same timeline
I want to this video get the best quality possible
Thanks for all the help !
Will you be doing this a lot, meaning a scripted solution would be easier and faster? Or are you willing to manually configure and submit an export job for every resolution on every video?

a lot … everyday 
The fast and easy way is to make a 4K timeline and edit in 4K. Then on the Export > Advanced panel, the export resolution can be overridden to be 4K, 1440p, 1080p, 720p, etc which means the 4K timeline will be scaled down. Bicubic is the recommended interpolator.
It isn’t necessary to wait for an export to finish before submitting the next resolution. They can be submitted back-to-back immediately and Shotcut will queue them up in the Jobs panel.

thx … I will try
The bulk way is to create and edit in 4K again, and export a 4K master using a high-quality codec like DNxHR or high-quality H.264/HEVC. Then use an FFmpeg script to transcode that master to different resolutions. Rerun the script for every new master created.
YouTube does this automatically for you, so I assume you’re doing this for a different service.

If you are happy with the Export > Advanced > override method, then it is possible to create an export preset for each resolution. Then, when you finish a video, click through the list of custom export presets and export each one. That’s relatively fast and provides great consistency.

If I understand correctly,
Your project must receive different resolutions on the same TL.
I would use the best one in video mode.
If it’s 3840*2160 50p, I would use that.
Then adjust the other resolutions with the zoom.
I don’t know how ShotCut reacts in this case (I haven’t edited with multiple resolutions or frame rates with ShotCut yet), but using Premiere Pro, it’s happened to me several times and no problems.
It’s best to avoid mixing PAL and NTSC frame rates.
If there’s a mix of 25p and 50p, exporting to 50p will simply double each frame of the 25p.
I just tried
Video mode in 2160 50p
Mixing FHD 1080 50p SD700 Panasonic with 2160 50p Sony A6700 and 2160 25P Sony AX100
ShotCut is surprising because it automatically scales 1080 to the correct resolution
Which remains 100 (strange)
On the other hand, 5 minutes for 1 minute 18 seconds of video
OK, ShotCut isn’t my main software, but only to recommend it in the forums, I haven’t updated my graphics card driver
So it exports CPU data for me
The export is excellent
If you have any doubts, I can put it on YouTube
When I read what the OP wrote again, this sounds more like what was requested. So ignore what I said earlier, as that’s a solution to a different problem.
Yes, that is standard functionality in Shotcut. So @ConteudoAnimal, do what @caraibe13420 is saying rather than what I said. You only need one timeline/project and only one export at the max resolution of your source videos. Since there will be upscaling involved instead of downscaling, use Lanczos interpolation.

That’s great!!
You can configure Premiere like that too.
Exceeded 5 minutes with ShotCut in CPU encoding.
48 seconds with Premiere using a graphics card.
I think I should update my GPU driver.
My card is an MSI NVIDIA GeForce GTX 1660 Super Ventus XS OC.
But since I only use ShotCut to promote the merits of this free software, it’s not my main concern.
When a PC runs well, you hesitate to make a change.
