I am sixty-three years and not very experienced with video editing. So please bear with me as I can be very verbose.
Firstly I started with the source from lwn uploaded by xxxlavalxxx. Thanks.
Then I corrected the sync issue from 1h 34m on and increased the volume a little.
However I found the Chinese subtitles aggravating. I had previously downloaded Get On Up (2014) Blurred Subtitles-BDM uploaded by BigDogMoya.
I was very impressed with the results he had achieved and thought I would try it myself on Edge Of Tomorrow.
There are cropped versions around, but you lose nearly a quarter of the picture from the bottom.
So using the link BDM provided in his description for Get On Up I labourisly followed the tutorial over a few hours until I had a result.
I am quite happy with it, though I feel it could be improved with more practice.
The blur is quite noticeable but far far less intrusive than the subtitles. I did not worry about the watermark.
Please let me know what you think (sample provided) and thanks to Big Dog Moya.
