Why my HD output pixelated

insi · Post by **insi** » Mon Oct 27, 2008 2:28 am

Hi..I am so sorry if this issue was brought before because I couldn't find it when searching or I don't know what to put in the search.

I am using X2.

Okay my issue:
If I create as DVD PAL for example, it turns out ok for my movie.

BUT if I created as high definition or HD movie, it turns out like pixelating especially when moving or fast movement for example flower blow by the wind so the flower edges will not smooth.

Is it because my monitor not HD resolution?

I want to display/export as 1080i but it won't work for moving object even for people walking it turn out pixelating but for slow movement it turn out ok.

or must the original AVCHD must be 1080i resolution? I read that my canon HG10 is not fully 1080i eventhough it stated in the spec full HD 1080i.

Please help.

Thank you in advance.

Recently Ken had posted a reply explaining this. I don't use HD, so my response is limited to my recall of his post.

Basically this is a very common happening with HD video. Horizontal movement results in pixelization. It must have to do with the high number of pixels that HD video uses. I also recall Ken reporting that this does not seem to be present or as present with Vertical movement.

So any panning should be limited to very, very slow, and very short. Objects moving in your shot, really should not pixelate much. When rendering do you have Smart Render enabled? If so try rendering without Smart Render.

For better search results, try searching for AVCHD and using Ken Berry or etech6355 as the author. They are our resident experts in the newer HD fields..

This is the post that I think Vidoman is referring to:

But you also might want to take a look at http://phpbb.ulead.com.tw/EN/viewtopic. ... 408#169408 where I try to give some more general advice about editing AVCHD.

As for whether or not the HG10 gives 'true' 1080i, the short answer is: yes it does. However, what you probably read is also true -- though it films natively in full 1920 x 1080i resolution, this is downgraded in the camera to 1440 x 1080i. I am not sure why Canon did that -- maybe because the equivalent HDV high definition frame format was the same as that... But I think you will find it is still excellent quality...

Thank Ron and Ken.

I will try again later to create it in lower resolution and see what happen and also try without smart rendering.

So far I don't mind in standard def but hopefully after I am getting a new HD monitor I hope it will show as HD

As long as everyone has the same issue then I fell a bit relief and hopefully future software will fix it.

I shoot with Canon XLH1 - make sure you have upper field first set when rendering or in properties when making dvd. if you have lower field first set and ulead is forced to flip it can contribute to artifacting. also be sure and try and stuff as high a bit rate (I use constant) that you can get onto the DVD if that is your output.
