This script will convert playblasted image sequence to a mov file. All happens in the background and there is no need to dig for the files or do any extra work. It uses TCL scripting and there are couple of things to do before using but it's all explained inside the script. Hope it will save you lots of time. It does not support audio yet but I'm working on it.
POSSIBLE PROBLEM with profile names with dots:
The script will actually look into your profile's "temp" directory to find the png sequence and will create the tcl script, the .bat, and the temporary .mov into the same folder. I found that the tcl language doesn't tolerate well dots in profile names. So if you have your profile inside your Documents and settings called firstname.lastname that could be a problem. Quick solutions for this is if you create a folder called "temp" lets say on your C drive (so you'll have C:temp), then go to your control panels -> system -> Advanced -> Environment Variables and edit your user variable for TEMP and TMP and change the variable value to C:temp and do the same if possible for the system variables (TEMP and TMP) as well. After this you'll need to restart Maya (recommended to restart the computer actualy). Maya will not save any temp files anymore into your profile but into the C:temp.
