Thanks again
As long as you don't process the video stream, the quality will be preserved. You can repack the video into a different container, as long as you don't touch the video the quality will be kept.
Now you deinterlace and re-encode the video. That means you process it. Therefore you will inevitably affect the quality in some aspect. Deinterlacing for example reduces (halves!) the temporal resolution which can give the impression of lost sharpness and crispiness, in addition to introducing artefacts due to the synthetization of the missing field.
As has been mentioned, there are better deinterlacers than yadif.

Edit:
You won't loose temporal resolution when you bob-deinterlace your video, means doubling the framerate
In Handbrake:
Deinterlace: yadif Preset: bob Interlace Detection: Off
Framerate (FPS): 59.94, Constant Framerate

Still, for every frame the missing field will be synthesized (interpolated), hence it is also not free of artifacts

But perhaps you like the result better.
