how to convert DV cam to DVD using TMPGEnc? please help...

[edude]

I have a Sony DV camera and want to burn DVDs of home videos for the family.

when I load the DV-cam AVI into TMPGEnc, there are interlace "artifacts" between frames in high-motion sequences. So I turned on the "deinterlace" filter in TMPGEnc (adaptive even) and that eliminates the interlacing.

I've encoded 2-pass VBR 5000kbps avg., 9000kbps max for DVD, and have made some test DVDs. The sharpness of the individual frames look excellent, however fast motion in the video does not really appear smooth - where the interlacing was is now kind of jerky. There is no "blockiness" or anything (I'm assuming the high bitrate is eliminating that), but the motion does appear like something has been dropped.

Should I *not* de-interlace? Should I be encoding to a different frame rate (DV source is 29.97 and I'm encoding to 29.97 for DVD)? Should I encode to non-interlace? Right now I'm targetting NTSC DVD with interlace.

Many thanks for any advice !!!!

It sounds like you started deinterlacing based on seeing the artifacts in TMPGenc instead of on a finished DVD. Is that true? I have no experience with DVD (maybe next year), but for DV -> SVCD, I don't deinterlace and see no artifacts other than occaisional "jaggies" on angled, straight lines which is a part of all DV video.

what have/will you use to burn your DVDs?
i am unclear what you are evaluating your clips on: tv or pc.
assuming your dvcam is not progressive scan capture and your endpoint is a TV, you should stick strictly to interlace everywhere.

OK, I see...interlaced TV may show OK. that makes sense, because the TV is interlaced. I haven't tried it non-deinterlaced against the TV yet...it just looks so awful in TMPGEnc preview.

thanks for the pointer, I will give it a try !!

i'm using a pioneer dvr-a03, and am evaluating the final DVD on TV. i am re-encoding now with interlace on everywhere and will try burning another DVD.

how can I tell if my DV cam is progressive scan or not? i can't really tell any difference on the PC if I change the video settings in TMPGEnc advanced settings and do a Preview from within TMPGEnc... do I need to burn DVDs using both settings and compare how they look to each other?

thanks - this is really helpful !!

for your dvcam, the documentation for the unit should tell you if it is progressive scan. most dvcams are not. if you provide a make/model, i might know off hand.
for previewing, i do not preview in TMPGEnc. instead, i use windows media player or sasami2k. this allows me to blow up the video to full screen on my pc to evaluate artifacts.
ultimately, if your dvd media isn't burning up your wallet, then the true test is to burn variants and evaluate on tv.

it's a sony dcr-pc1, i got it new a few years ago. now i just gotta find the manual... if you have any ideas as to it's output type, muchly appreciated. i tried finding info on the web, but couldn't find anything conclusive.

i tried several different TMPGEnc encodes, and authored a DVD with all of them on it (progressive input vs. interlace field a and b), and when viewing on the TV, the source as progressive one looks awful (blurry sort of interlacing). selecting interlace input, however ends up with an *incredible* encode on the TV. viewing it in the DVD authoring software looks awful, but the on the TV it looks awesome. so...it looks like my dvcam has interlace output? i need to try more tests to see if field a is better than field b.

i'm using DVD-RWs for these tests - VERY handy, you can just erase them and re-use them!

i have a sony pc110 and it doesn't have progressive scan. i think it's a safe bet u don't get progressive scan in a sony until you spend over $2K USD. other makes have it for less. add to that the fact that your tests show much better results with interlace, and you must not have it. my cam is bottom field first, so i can only assume yours is too. if you pick the wrong field, you'll know it when you picture jitters all wacky.
to understand the blurriness you see, read this: http://www.geocities.com/lukesvideo/interlacing.html.

how much is the DVD-RW media, and how many minutes can you fit on one?

i'm re-encoding some high-motion DV with both a and b now. many, many thanks for the heads up re: the interlacing link and the other info, very helpful indeed !!!

i bought a 5-pack of genuine pioneer dvd-rw for about $75, although you can get generic brands of -rw for as low as $6 (check pricewatch). the dvd-rw's hold 4.7GB, same as a standard DVD, and are very handy for data backup as well.

using 2-pass VBR you can really max out on quality when minimizing on disk usage. at 9000 max, 5000 average i'm seeing roughly 40-50MB per minute of video. i could probably lower the bitrates to hold more while still maintaining quality, but haven't gotten there yet as far as testing. (that comes next )

i started out playing with SVCD/XSVCD/XVCD, and the quality was really good, but once you try DVD you won't go back - it is really unbelievable !! the costs are really dropping for the media, which makes dvd even more appealing.

many thanks again for the help !!!

actually the link works OK if you remove the period "." after html, i.e.,
