Makeavi


Discovered a neat windows (and vista) tool for turning image sequences into videos: http://makeavi.sourceforge.net/


1280x720 in the 'Microsoft Video 1' format worked well, though 57 MB of pngs turned into 135 MB of video. 'Uncompressed' didn't produce a video just a small 23kb file. 'Intel IYUV' sort of produced a video but not correctly. 'Cinepak' only output a single frame. 'VP60 Simple profile' and 'VP61 Advanced Profile' with the default settings worked, and actually produces video smaller than the source images, though quicktime player didn't like those files. Vimeo seems to think VP61 is okay:


More Velodyne Lidar - overhead view from binarymillenium on Vimeo.

This new video is similar to the animated gifs I was producing earlier, but using a new set of data. Vimeo seems to be acting up this morning, I got 75% through an upload of the entire file (the above is just a subset) and it locked up. I may try to produce a shorter test video to see if it works.

I have around 10 gigs of lidar data from Velodyne, and of course no way to host it.

My process for taking pcap files and exporting the raw data has run into a hitch- wireshark crashes when trying to 'follow udp stream' for pcap files larger than a couple hundred megabytes. Maybe there is another tool that can do the conversion to raw?
