| Hi All -
I'm trying to convert an H.264 encoded MOV file to an FLV file. All appears to be going fine, I get no errors on the encode, but when I play the FLV file back it is INCREDIBLY choppy (even though it reports it is playing at 30fps) and the audio and video are very, very out of sync. The log follows below. If it would help, you can download the source video at http://www.performancecoaching.ca.s3.amazonaws.com/self_talk.mov and the resulting FLV file at the http://www.performancecoaching.ca.s3.amazonaws.com/self_talk.flv Any help very appreciated for a frustrated man ..
