Motion blurring...Think its occurring in the conversion proc

[Divxwannabe]

Hi all,

Think I am in the right place..(excuse newbieness). Having a problem with what I think is conversion. Heres what I did. DV camera to HD via Firewire, real time capture mpeg 2 via Ulead vs 6. Seemed Ok, dropped about 180 frames in a 45 min clip (bummer, gotta work on that).

Be that as it may, burnt to DVD, alls fine, expectations kept in check by my inexperience. Final output hardly noticed dropped frames. However, what I did notice was that while happy with the way DVD looked on my TV via DVD player, there was an effect, that whenever the camera panned, (on the source) there was a blurring of the picture. When the camera was not panned quality was OK. I am hypothesising that it may have something to do with the way Ulead vs 6 captures in MPEG 2 (note on the fly from the camera, did this to cut down on rendering times, getteing pi**ed with the way Ulead keeps re rendering) . No editing straight to output by Neo DVD, no re rendering there. The concept is good to back up camera tapes. However, I am coming around to think that it may be better to capture in dv avi (ulead does a great job of this, splitting scenes by time) then encoding to mpeg2 vis TMPgenc plus. Anyone else had experience of this blurring of motion effect..?

This is called deinterlace, check it out here.

You are better off doing the transfer to your computer using DV AVI since this is more of a transfer than a capture. Should have no dropped frames and no sync problems.

Then you can convert to MPEG-2 using a stand alone MPEG encoder such as TMPGEnc Plus or CINEMA CRAFT ENCODER or MainConcept MPEG encoder.

Since the encoding will be done form the file it is not real time and the quality (with the proper settings) will be better.

No deinterlace this way!

Hi Fulci, Glad to see you've crept out of the crypt for easter.
Does deinterlace really matter if you intend to watch on TV?

You should only deinterlace the video when it is intended for playback on a computer monitor. Formats such as VCD or DivX and Xvid etc.

When you deinterlace you are going to loose quality so you only want to do it if you have to do it.

No need to do it for a TELEVISION be it regular or HDTV

Gentlemen, as usual your timely replies are very much appreciated. Looks like avi thence to Mpeg is the way to go...


Many thanks!

Phew, no deinterlacing vs interlacing, just read that www.100fps.com , err I'll just give the avi to TMPGenc plus a go...This video stuff has a lot steeper learning curve than the all in one vendors of Video editing software would have you believe.....!!!

Will keep trialling various methods...

Again thanks..
