I want to save some videos that come from PNG image sequences. They are not videos to upload to a public platform, they are restored family videos and I would like them to be compatible for viewing on smartphones, TV, etc.
Most of these videos are 720 x 576 px 25 fps resolution.
So I want to save the videos in two ways.
a)For archiving. Maybe Ut Video profile (lossless) in Mkv container to preserve also the original audio track (This is multiplexed in external software)
B) For consumption. For viewing on usual home devices, with smaller size and better compatibility.
Normally I use the H.264 Youtube profile for the consumption purpose (b), but I noticed that there is an H.264 lossless profile (without visual loss).
I made my export in this profile and in the Youtube profile and it turned out that the video exported with the H264 lossless profile occupied less size.
I know that there are values and parameters that make the difference between both profiles (CABAC, GOP) although I don’t know what is their practical use.
What is the advantage of the H.264 Youtube profile over H.264 lossless?
I thank you in advance for your advice and comments.
