Value to using deinterlace filter with a p-scan player

[Smells_Like_Feet]

I am in the process of transferring home video (camcorder) video to dvd. I capture it as an avi (huffy codec), frameserve with vdub (using deinterlace filter among others), and then use TmpegEnc to encode to dvd compliant mpeg. My question follows:

Since the original source material is interlaced should I use filters to create a progressive video during the encoding or should I maintain the interlaced video and allow my dvd player (panasonic CP-72) do the progressive conversion for me? The CP-72 makes use of the Sage/Fourajda (sp? ), one of the best hardware deinterlace chips out there. Or is there additional value in encoding to progressive and then still using the progressive output of the player?

Thanks for the help!

Even DVD's, are often telecined to 29.976 frames per second, which introduces interlaced frames to a progressive stream. The primary bonus to a progressive scan player, is the resolution it will output, and not the format of the video, be it progressive, or interlaced. Save your efforts for other things.

Thanks for the reply DJRumpy. So will I derive a benifit from using the deinterlace filter in VDUB or am I just spinning my wheels? The reason I ask is that I just received a DVD-burner and want to do lots of encoding. I am wondering if adding this filter and fameserving is adding significant time to the encoding process. Right encoding with TMPGEnc is taking a loooooong time on my 750MHz AMD processor and I am looking for any way to speed it up Again thanks for any and all help.

If your source material is telecined, then I would spend the extra time to inverse telecine it, simply because you gain back those extra frames, saving space, and bitrate for other things. If your material is true interlaced, then I wouldn't bother. It all depends on what your working on.

If you want to use a quick and dirty IVTC method, open the AVI in VirtualDub, and from the Video Menu, select FRAME RATE. Select "No Change" for the source setting, and "Reconstruct From Fields - Adaptive" for the Pulldown setting. Save your avi for a few minutes and view the results.

It's better to learn how to identify your source, rather than guessing if it's telecined, or true interlaced. Check www.lukesvideo.com
