Hi Ron. Both of these videos part 1 and 2 had the same 1080 and 4k recordings. One was edited as 1080 and uploaded as 1080. The other was edited as 4k and uploaded as 4k. I was curious to see if RU-vid would do a better compression of the 4k file which had a higher bit than the 1080 version. The originals for both look better than the ones on RU-vid due to the compression of the footage. In the past I only edited in 1080, my 4k footage was downsized in the editor and then uploaded as a 1080. Now I have a computer than handle 4k, I edit everything in 4k and then upload as 4k. I hope that answers your query.
