I had seen other posts about "jerky" video and the suggestions to use software rendering. I've tried different project settings in MyDVD as well ("Same as Original, EP, etc). The re-rendering in MyDVD appears to be the source of the jerky playback. When played by itself (such as in Windows Media Player), the mpg file that this setting produces plays back smoothly. Unfortunately, MyDVD still re-renders video output with this setting and the result is jerky playback. I figured that this might be the one that would work well for this source material. I was quite encouraged to find the "MPEG-2 High Definition 720p" option on the "High Definition" menu because it was 1280x720 29.97 fps.
The 720p types (Blu-ray AVC EP & AVCHD 720p) from the "High Definition" menu The 720p types (Blu-ray AVC EP & AVCHD 720p) from the "AVC (H.264)" menu All of the types from the "Blu-ray Authoring" menu I've tried rendering projects out to many different formats (from VW) to try to find something that MyDVD wouldn't re-render. This yields a significant quality degradation and results in video that is jerky and does not play back smoothly. However, when trying to add VW projects (or video rendered from a VW project) that contains anything other than a single mts/m2ts file (such as two mts/m2ts files or mts/m2ts files and jpgs), MyDVD will always re-render/encode the project/video.
When adding movies to MyDVD that consisted of either a single mts/m2ts file or a VW project consisting of a single mts/m2ts file, MyDVD would not perform any rendering/encoding and write (SmartEncode) the video clips directly to the DVD. I created an AVCHD DVD to test out on my Blu-ray player.
Initially, I did a test to see how the HD video would be rendered. The rate varies a bit but is usually a bit under 15000 Kbps. File specs are: 1280x720 59.94 fps (uses two "frames" for each image). The files in question are mts/m2ts file from a Panasonic Lumix camera that uses the AVCHD-Lite codec.
I've run into some issues trying to create DVDs using AVCHD video files.
