Mpeg 2 encoding + Authoring

[nikos8]

I am new to the game so ill try and give as much info as you guys need to help me with this one. I have been capturing my home videos and trying to convert to mpeg 2 (with tmpeng) so i can burn to dvd. After weeks of reading the guides here i finally did it and placed one movie on a dvd just to see how it looked. When there was any type of rapid motion the image was like there was a double/triple image ( e.g when a hand moved it seemed like there was a second hand trailing behind the original). This especially occured after converting to .vob files, using both tmpeng author and ifoedit. However i noticed when i converted to mpeg1 i didnt get this problem. I have tried changing bitrates and from CBR to VBR but i still get the same thing.

So my question is......am i doing something wrong in Tmpeng or am i not capturing correctly from my camcorder via firewire?

Any help would be greatly appreciated.

Thank You

Where did this happen at? On the computer, on your TV. If on your computer, what player(s) did it happen on?

[nikos8]

both the pc and tv

Okay. Now when you encoded the MPEG on TMPGEnc, what template did you use?

[nikos8]

i used the DVD(PAL).mcf template.

thanks for helping.

Sounds like you have used the wrong field order. Try your encode again, but this time swap the field order to the opposite of what the TMPG default is on your system.

[Tommyknocker]

I am not sure I have helped yet. Anyway, my DVD PAL template has motion search precision set to Motion estimate as default. If yours is too, try setting it to a higher quality and encoding only a few minutes of your video. Let me know what happens.

[nikos8]

i regret to say that it is still happening. I tried on highest quality with automatic VBR

[Tommyknocker]

And did you adjust the field order like Energy80s suggested?

[nikos8]

also i dont know if this bit of info will help. When i view it as an mpeg 2 file and not a vob file what happens around the areas of rapid motion is the image is shown with lines around it. There is no double image like i get when i convert to vob.

[nikos8]

i thought youd ask that

Let me try now

[Tommyknocker]

You capture your video to your computer as DV. You convert the DV to MPEG-2 DVD, and burn the MPEG-2 with TMPGEnc DVD Author, right? Where does the VOBs come into play?

[nikos8]

sorry for being such a noob. reversing the field order fixed the problem. Just out of curiosity can someone tell me why?

Also i think now i will buy the full version of tmpeg

Your source is interlaced video. With interlaced video every frame has 2 fields(frame being the full image and field being half of the full frame, each field has every other line. When merged together they make a full frame/picture. The reason they did this is rooted back into the first days of broadcast TV. It's a long story and really not important at this point in time.)

What is hapening in your case is that the fields are being put together out of order, which makes things look hinky because each successive frame does not match the one that came before it, and the reconstruction of the 2 fields is all wrong, which causes jittery video and other problems, especially with higher motion video.

Thanks for the explanation. Greatly appreciated
