metichemsi I believe this comparison was not about the smaller file size (same video quality at lower bitrate) but about showing the AV1 codec video quality advantages over HEVC (using the same bitrate for both) which in this case resulted in a similar file size for both.
On the other hand, if you look at the MediaInfo data, you'll notice that there's more to it. For example, using Full Color Range in AV1 vs. Limited in HEVC which add more complexity to do and more time to encode and more data to add, which results in a bigger file size of course.
Add to this the new techniques SLR is used like the improved color grading and better stitching...etc.... Yes, they are part of the Video post-processing, but remember they are still more data to add to the final file size as well.
My only issue with the whole comparison was not the file size because I understood what's going on and what's SLR's intensions, but with the 200Mbps target for the Original/ High bitrate upcoming video releases. Because these both samples are in about 122Mbps.
As I love the highest quality possible and to be as close as to Camera RAW files regardless of the video file size, I'm all with AV1 "EVEN IF" it was larger in size than HEVC with all these improving techniques to be honest.
In the end, I'm talking about the Original/ High bitrate videos. The whole situation could be way different for the streaming videos. And let's hope for the best for both video options.
Best Regards.
