How to make words in ASS subtitles appear one at a time ?
21 septembre 2022, par ThaDonI am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.



What I mean by this is, a word will appear, then another word will appear next to it, and so on. Eventually the line will clear, then repeat.



Example :






I thought I could create an Advanced Substation Alpha file where subtitles share the same end-time but differing start times, however FFMPEG doesn't seem to cope very well when rendering the file :



[Script Info]
; Script generated by FFmpeg/Lavc57.107.100
ScriptType: v4.00+
PlayResX: 384
PlayResY: 288

[V4+ Styles]
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding
Style: Default,Arial,16,&Hffffff,&Hffffff,&H0,&H0,0,0,0,0,100,100,0,0,1,1,0,2,10,10,10,0

[Events]
Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text
Dialogue: 0,0:00:00.00,0:00:03.46,Default,,0,0,0,,I'm
Dialogue: 0,0:00:01.00,0:00:03.46,Default,,0,0,0,,a
Dialogue: 0,0:00:01.50,0:00:03.46,Default,,0,0,0,,subtitle




The idea being that
I'm
would appear, then 1 second latera
would show up next to it followed bysubtitle
a half second later

ffmpeg to cut beginning and fade in audio
31 juillet 2024, par cannyboyI've got a bunch of spoken word mp3 files, which all have the same intro talking and music, and then the real content begins. So it goes roughly like this :


00:00 Standard intro spoken word
00:20 Standard intro music
00:35 The content



The timings are not always the same (can vary by 5 secs). So I'd to cut the first 25 seconds and then fade in the next five seconds. And then output the file in the same mp3 format. Is this possible with ffmpeg ?

is there a way to preload low quality in MPEG Dash or HLS so there is always something to play ?
5 mars 2018, par Daniel BenedyktI created HLS manifests and DASH manifests with different resolutions and bitrates.
The videos almost always starts low quality, then picks up quality/resolution.
But later, if Internet speed drops, the video stops because its playing the hi resolution video.
is there a way to preload low quality in MPEG DASH or HLS so there is always something to play ?
Edit : I have the video preloaded. its not live streaming but once it starts playing, I am looking for a consistent stream, even if that means sacrificing quality.
