de-interlace options--now i'm confused????

[alucard2050]

i am capturing from satelite useing iuVCR and the Huffyuv codec. the files it produces have all those little lines in them. so i use the de-interlace setting on TMPGE and it clears it up. here's my question. i am now choosing none on the setting. What is even-odd,odd-even,even-even, and all those other settings for de-interlace?? thanks.......

is there anyone on here that can help? i've got alot of captures that i need to encode but i don't want to spend alot of time encoding till i'm sure what all the odds and evens mean....thanks........

Go with Even-Odd Field to DeInterlace a video.

This means, the video will play an Even field, then an Odd field, then an Even field, then an Odd field, ... you get the idea.

You don't say how you eventually intend to encode your video. If it's going to be MPEG2 then *don't* deinterlace! Also don't use any filters (like smoothing filters in VirtualDub) that don't understand field mode.

If encoding to MPEG2 with TMPGEnc make sure you set the source type to interlaced and you have interlaced output turned on too.

Also, I recommend you do a fast, low quality encoding first to check that you have the field order (A or B first) set right - if the video appears jerky then swap the field order.

Why is it bad to DeInterlace for MPEG-2 encodes? I do that all the time... if I don't DeInterlace them, there are interlace scanlines in the video, which make the video look bad.

i am useing TMPGE to encode to an Mpeg1 format. i understand what interlace and de-interlace is its just all the options in the menu that come after it. THANKS>.......

MPEG-2 is designed to work well with interlaced video. In other words you capture at say 480x576x25fps for PAL SVCD, but MPEG-2 will encode this (provided you configure the encoder right) as 50 *fields* per second, each field 480x288, giving much smoother motion. This is provided you haven't done anything to mash the fields together, otherwise the result is 50 fields/s of blurry motion.

Also, it makes a difference what you play it back on. Don't judge the result by playing it back on a PC, if you finally intend it for a standalone player - not all software players playback interlaced MPEG-2s right. ATI's MMC7.1 does a pretty good job on this.

Oh yeah - one last thing. The preview window in TMPGEnc looks *awful* when encoding an interlaced video. Don't worry about that, just wait til you see the result.
