I've got a series of images captured using a motion activated camera-right now, I'm doing a bit of processing on them and each image is stored as a PNM/PBM file but I can easily convert them back to PNGs. I have a unix timestamp of when each were first created. I've also got an audio file (where I know the starting time), recorded over the same period.
Is there any way I can construct a lossless video that should be playable from VLC from these images? Ideally, I'd like the audio to sync.
