still pano from video

[Battle]

Some time ago I saw on this forum, I think, a video of stills being extracted from a video taken of a tower, and assembled into a still. Seems like it was European tower of some kind.  There was a hyperlink to an external site.  I was trying to find this thread in order to solve the opportunity described below.  Thanks in advance for you help.  

I want to take video, extract stills, super resolution (optional), and assemble a finished still panorama.  I searched that archives, and can't find the item I mention above, can can't quite find an appropriate thread that answers how to do this.  I could use some pointers on this process.  

Thanks,

Battle

I haven't tried this, but you can use ImageMagick to extract
individual frames from a video as JPEG or similar. You could then use
Hugin normally to stitch those images.

Yes, after extracting the video frames, the process turns into a regular stitch. I usually extract frames with FFMPEG - which runs under many operational systems. I guess for windows there is a version called WinFF.

The trick is to get good quality frames. If you extract to a compressed format, like jpeg, you better defined a better quality than the default. Under linux I would do that with a command line like this:

ffmpeg -i input_video.mp4 -q:v 2 output-%05d.jpg

Good luck,

Carlos,

I did get VLC which uses FFMPEG to work to extract still images which are OK quality.  

Thanks,

Battle

The process is quite simple once you’ve extracted the frames from the movie.
Here’s a little tutorial I wrote 7 (!) years ago: http://habi.gna.ch/2009/04/10/panoramas-from-low-quality-movies/
Obviously getting a movie off an iPhone is much easier now, but the other points in that post are still valid.

Depending on the format of your movie, you can use ImageJ (http://fiji.sc/Fiji) or VLC to extract the frames, and stitch those with hugin afterwards.

Hope that helps.

Habi,
Nice tutorial. Thank you. I successfully extracted images using VLC. Any thoughts on super resolution from video?

Very welcome!

Not really, since I’m not familiar with super-resolution imaging.
Can you give me a quick rundown of the process?
