RussianQuestion
I have 28,000 images I need to convert into a movie. I tried
mencoder mf://*.jpg -mf w=640:h=480:fps=30:type=jpg -ovc lavc -lavcopts vcodec=msmpeg4v2 -nosound -o ../output-msmpeg4v2.avi
But it seems to crap out at 7500 frames.
The files are named webcam_2007-04-16_070804.jpg webcam_2007-04-16_071004.jpg webcam_2007-04-16_071204.jpg webcam_2007-04-16_071404.jpg Up to march 2008 or so.
Is there another way I can pass the filenames to mencoder so it doesn't stop part way?

Solution
Shove the list of images in a file, one per line. Then use mf://@filename
OTHER TIPS
You might be better off going to #mplayer or #ffmpeg on Freenode IRC for specific help with those programs.
You can create a video from a sequence of images using LiVES: http://lives.sourceforge.net
Simply place all of the images in a directory, and make sure they are in alphanumeric order. Then in LiVES, just go to File/Open File or Directory, and double-click on the image directory.
Once the images have loaded you can edit the clip and save it in a variety of formats.
another alternative is to bypass mencoder and use ffmpeg directly
Kinda of an odd answer... but I thought that Blender could construct videos from sequences of images. Just a thought.
