So I'm switching my workflow to start recording in HLG to future proof my videos and then using color charts and grading to change it to rec 709, which I have ready to go and that's all working perfectly. My main question, even after many videos on youtube that try to explain this, do I need to grade the HLG footage like extending the shadows and highlights (it's extremely compressed right out of the camera) and other things or do I just cut/edit and output it in the HLG format in Vegas Pro (without changing the highlights/shadows) and the video will play normally on a TV that supports HLG? I've seen people say you can just play the raw HLG file on a TV that supports it and the TV, itself, stretches the highlights/shadows, and makes everything look great, but other videos have me grade it - but are those videos only talking about outputting to 709? I'm so confused.
Basically I'm asking how to get HLG raw footage to play correctly on an HDR display that supports HLG.
