Ok, Â
DVCPro HD is less compressed than AVCHD. What does that mean?
Compression is kinda complicated. In simple terms I like to explain it as: Compression is throwing out redundent information to achieve a smaller file size, but at the same time, tricking your eyes (and ears if working with audio) into thinking nothing was thrown out. Even though you may not notice it, video that is more compressed (aka has a smaller file size) will have a lower quality image than video that is less compressed...because more information was thrown out. Make sense?
So, DVCPro HD is less compressed and has better image quality than AVCHD because AVCHD is more compressed, in fact, more compressed than the HDV codec, which is known to be buggy. Â
So you may be thinking, "Well why would anyone want AVCHD?" It depends what you're shooting. If you're shooting a wedding and don't have a lot of time to transfer the video from the card to a laptop so you can have a fresh card to continue recording, then you will want AVCHD because it's more compressed. And like I said above, more compressed = smaller file size. Smaller file size = fitting more video onto a card.Â
If you're using a 16GB card, you will fit more AVCHD to the card than DCVProHD. The downside is that the image quality is degraded. Â
