To celebrate and to help introduce new users to the power and ease of FFmpeg, I created this entry-level tutorial for single and two-pass encoding with FFmpeg.įor the record, many of the major changes to FFmpeg were at the application programming interface level, so if you're driving the program from the command line, you'll see little difference. Thankfully, Lorenz didn't "break" any of the command strings that I tested from my FFmpeg book, Learn to Produce Video With FFmpeg: In Thirty Minutes or Less, or courses, so hopefully, it won't break existing command strings for other users.
