Hi! I've done something similar to doing this, but I ended up using a
non-linear video editor. Specifically, I used kdenlive. It can do keyframe
animation, so combine that with fade-ins/fade from blacks

You might have better luck using a file carving utility, like photorec and
search/recover just MP4 files or mounting the drive imag

The MP4 container is limited as to subtitle support. See
http://en.wikipedia.org/wiki/Comparison_of_container_formats. SRT or ASS
isn't supported
Default codec for a mp4 is indeed libx264, crf 23, preset medium. No fast
start.

What are default encoding for ffmpeg? For example, it seems when I use the
below command
>ffmpeg -i video1.wmv video1.mp4
the default is libx264? correct?
Also, is the default for ffmpeg to fast start or I have

Hello, Bhikku. I'm still relatively new to these mailing lists, but I
think I can help you out some.
My main observation is that you are doing 2-pass encoding using x264
for video compression. x264 has another variable bitrate mode called
Constant Rate Factor. With this, you do not determine what
39 matches
