AVCHD (Advanced Video Coding High Definition) is a high compression codec based on H.264, which is good at presenting videos with great quality and good file size. It is designed to be compatible with Blu-ray Disc format and can be used for authoring and distributing of high definition video on DVD media. The file size of a DVD can be reduced by half if the DVD is converted to AVCHD format.

Then, why not backup the DVD 9 movie into AVCHD to fit on a DVD 5 disc, instead of shrinking the DVD to DVD 5 using DVD Shrink as most of us usually do? After all, AVCHD can give us much better quality. If you are thinking of this question, following are some facts for you to refer to:

1.An AVCHD disc requires a Blu-ray player, while a shrunken DVD with MPEG-2 codec disc can play in any DVD player.

2.DVD Shrink doesn’t re-encode the video and the process is fast, but if you shrink too much the quality suffers compared to using a good MPEG 2 encoder like DVD Rebuilder to re-encode the DVD as I talked in this article. By contrast, converting a DVD 9 to 4GB AVCHD will take much longer than shrinking or recompressing the DVD to MPEG 2, although it will give better quality.

3.You won’t get HD (high definition) video out of the conversion but SD (standard definition) video, so the quality gain you get from converting to AVCHD is not much but the time it takes is much. It may be worthwhile if you want to put two or three movies on a single disc.

Therefore, if you have a Blu-ray player and you think it is worth spending the long time to convert the DVD to AVCHD, you can do it. There are some free software tools to convert DVD to AVCHD format and multiAVCHD and Ripbot264 are the top two I will recommend.
