[_] How to lossless make video swfs Anonymous 12/22/15(Tue)20:27:40 No.2982930
Since people are going to use swfh264 whether you guys like it or not (feel free to yell about it
in the replies), here is a guide on how to cut and wrap an mp4 into a swf without re-encoding it.
Requires ffmpeg and a bash-like shell. For Windows, I use http://babun.github.io/ as my ZSH shell.
Assuming you have an mp4 with h.264 video and AAC audio:
1. Use ffmpeg to split mp4 into several seperate sections based on keyframes, copying the video
and audio codecs:
>ffmpeg -i [video file name] -acodec copy -f segment -vcodec copy -reset_timestamps 1 -map 0
OUTPUT%d.mp4
2. In the files labeled OUTPUTXX.mp4, find an appropriate starting and ending file.
3. Delete the files before and after the selected video files, but keep the ones in between.
4. Generate a list of the files to be concatenated. cd into the folder and run
>"for f in ./*.mp4; do echo "file '$f'" >> mylist.txt; done"
5. Use the generated list to concatenate the OUTPUTXX.mp4 files.
>ffmpeg -f concat -i mylist.txt -c copy test.flv
6. Take test.flv and feed it into swfh264
See the attached swf for an example. Compare with:

Since no one's asked yet, what's the name of the song?

Are you implying that you could make this clip look better in Sorenson Spark H.263, which is the
codec used for streaming?
I would honestly be happy admitting I am a faggot if you could, because I've tried countless
methods to make good quality videos at h.263 (like, say, Youtube 480p quality), and it utterly
fails unless the clip is ~30 seconds at 360p. I can get better results out of a 4MB webm than I
can out of 10MB of Sorenson Spark H.263. Even variable quality does little improvement.
If you say "you shouldn't make video rips to begin with," than that is a different matter.

Thanks you too.
