K-F subs are the best subbers for One Piece but their video quality was ok so I converted their subs into soft subs and used a higher quality DVD rip. I also wanted to edit One Piece to reduce how long it takes to watch it. This edit is not like One Pace where a lot scenes were taken out.

Video:
Best quality I found originally from ChaosBlades’s One Piece 1-336 [HQ][Dual-Audio] Movie 8+10 [1080p][Dual-Audio] which is DVD quality.
I chose ChaosBlades because they have more clearer and thinner black lines which makes it more crisp and better looking, esp. in the close ups, while cloaknsmoke while having much better detail in the backgrounds has problems with a lot of noise and flickering which is annoying to me.
I wanted to use the original DVD 4:3 version not the Widescreen HD as it crops the top and bottom of the video.

Audio:
Japanese

Subtitles:
K-F Soft subs - Converted all from original K-F video hardsubs.
There are some differences from original: A lot of the special attacks for minor characters had stock font or was not animated so I made unique attacks for everyone.
Some special attacks color has been changed.
K-F subs updated and changed their special attacks font (e.g. Usopp) and their names across the episodes so I made sure to choose one and keep them consistent.
Kept in the special attacks for Crocodile that were made in after effects.
Made more notes to explain certain things but took out others. Changed font of notes.

Edits:
I edited out a lot of the redundancies to make One Piece more smoother to watch including recap of previous episodes, opening and ending songs, and other scenes or parts of scenes that felt too long or not needed.
Editing did not involve re-encoding but remaking so it keeps the same high quality.
