I am trying to replace the videos from the new Sonic CD remake (Steam PC version) for two reasons: 1. Missing Japanese vocals (understandable) and ringtone-quality instrumental replacements. 2. The video was cropped to fit 16:9 widescreen instead of giving the whole frame. Using the best quality videos from the Sonic CD DVD project as a source, I have the following command line set up to encode the video: (the grammar filter uppercased the "-I") Code (Text): ffmpeg -I "soniccd_op_640x448_Unrestricted 1pass lossless_29.970fps_all audio.avi" -vb 3000k -vcodec libtheora -acodec libvorbis -aq 10 -ar 48000 -map 0:1 -map 0:0 -map 0:3 "Opening.ogv" This is set to match the formats and stream mappings of the videos provided with the game. Unfortunately, when I start a new game, it simply skips the video and places me straight in PPZ1. Has anyone had any luck with doing something like this? I've seen a tutorial for replacing the JP audio stream (hence the 48 KHz parameter) but I want a complete replacement. Hopefully the game does not reject altered videos. I'm only worried about the Opening right now because the ending videos will take far more than a simple video encode. If my project moves forward, I will likely have to use an AviSynth script to shrink the video, add the credits, and add the good/bad ending variations.
