Render preset for lossless audio & playable video

[Perfect]

Hi
Which video settings should I use for container, extension, codec, bitrate
& rate control & which for audio codec & rate control to achieve lossless
audio best quality combined with a playable video that doesn't deteriorate
the audio?

Thank you for your amazing program.
I try to export a 1. music video with the fabulous set audio reference
audio video sync function but didnt succeed as the format that comes with
the flac export (ffv1) doesnt show the video on my laptop
My laptop is slow but I guess the music & video are synced.
To see it I want to create a custom render preset for lossless audio &
playable video.

As musician, lossless audio quality is important for me. The video visual
quality not. Can be mp4 if that doesnt deteriorate the audio.
The video just must be playable & the audio best quality lossless.
The original audio is a wav file with 44.1khz sample rate.

The edit render preset has settings for: container, extension which both
are by default set to x64 which doesnt show the video on my laptop & a
codec set by default to a64multi, while the audio codec is set by default
to comfortnoise & the rate control is set to (Not set) in both video &
audio.

Which video settings should I use for container, extension, codec, bitrate
& rate control & which for audio codec & rate control to achieve lossless
audio best quality combined with a playable video that doesn't deteriorate
the audio?
For video maybe mjpeg or mpeg4 & audio wavpack?
Thank you
