- Combine videos (this is a one-line command, however, text file works
better for some reason--see <http://www.github.com/expertmm/IntroCompatiblizer>)
```
ffmpeg -i "concat:Logo4 Animation A 1a0001-0100.avi|Logo4 Animation A 1a101-142.avi" -c copy "Logo4 Animation A 1a combined.avi"
```
`ffmpeg -i "concat:Logo4 Animation A 1a0001-0100.avi|Logo4 Animation A 1a101-142.avi" -c copy "Logo4 Animation A 1a combined.avi"`
* Even with text file, the names may need to be changed automatically
first to prevent ffmpeg syntax error. See
- h.264 avi to mp3 container for Sony software
```
ffmpeg -i "Logo4 Animation A 1b.avi" -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 "Logo4 Animation A 1b.mp4"
```
`ffmpeg -i "Logo4 Animation A 1b.avi" -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 "Logo4 Animation A 1b.mp4"`
- losslessly split
```
ffmpeg -vcodec copy -acodec copy -ss 00:00:00 -t 00:01:00 -i in.mp4 out.mp4
``
`ffmpeg -vcodec copy -acodec copy -ss 00:00:00 -t 00:01:00 -i in.mp4 out.mp4`
* where time after ss is start as hh:mm:ss, & time after t is duration as hh:mm:ss.
- losslessly change container e.g. from FLV to MP4:
```
ffmpeg -i VideoFile.flv -vcodec copy -acodec copy VideoFile.mp4
```
`ffmpeg -i VideoFile.flv -vcodec copy -acodec copy VideoFile.mp4`
* allows Premiere Elements to load it (tested where flv was AVC video with AAC audio)
- convert video to image sequence:
```
ffmpeg -i VideoFile.m2v Forensics1a%d.png
```
`ffmpeg -i VideoFile.m2v Forensics1a%d.png`
- convert image sequence to video:
* Tried with image sequence in folder: $HOME\Videos\Projects\Rebel Assault IX\RAIX2b\Scene07 (Lightsaber Duel)\forcegrab\2b4 (2013 3D Hilt flying away and back added)\
* Force fps such as 29.97: `ffmpeg -r 29.97 -i RAIX2b4-scene-lightsaberduel-shot-forcegrab%04d.png -sameq -r 29.97 output.mp4`
