I have a Samsung HMX-Q10 camcorder which records HD video in H.264/MP4 format. While attempting to put together a DVD of my videos in TMPGEncAuthoring Works 4, I try to edit each video clip, but the preview playback only plays the first half second or so normally, and then it stops moving completely. The audio continues to play. It seems the program chokes on it. I can play the videos smoothly through Windows Media Player. I also have the latest version of Quicktime installed on my computer. I have the "low resolution" option checked, but the help says that may not work with certain video formats. It seems to make no difference, so I assume the H.264 is one of those exceptions.
I am running an AMD A4-4000 Richland 3.2GHz Dual-Core CPU, with 4GB of DDR3 1333 RAM. My main hard drive is a 1TB, 7200RPM w/64MB cache, SATA, 6GB/sec Western Digital. The videos reside on a secondary SATA drive.
Does anyone have suggestions on how to get the preview video to play back smoothly? I upgraded my computer JUST for the purpose of editing my HD home movies, so it is quite a bummer to find it still not working. Would upgrading to version 5 work? Or should I install a specific codec to decode the H.265 video faster? Would moving the video to the main hard drive be better? Thank you!
