  1. Hey again guys,

    I'm converting Hi8 tapes to DVD, using DV interlaced video as the source capture. I then burn the DVD interlaced, and play it back on two players. First player, panasonic bluray player BDT-310 connected to plasma display. It looks pretty BAD, wavy lines appear during panning and lots of artifacts. I looked at the settings but there's nothing to tweak. Is this an example of a interlacing-unaware player?

    I played it back on my playstation 3 connected to a projector and it looked better , however i saw those black comb lines, pretty apparent actually.

    I also hooked up bluray player to a 4:3 tube tv, and no difference. Do I actually need to buy a dvd player that "knows" how to handle interlaced material? How would I know if it does. Or is the best solution to burn the dvd de-interlaced and suck up the quality loss in exchange for smoother video?

  2. All DVD and Blu-ray players and TVs support interlaced video. You did something wrong with the editing or encoding. Maybe the wrong field order or improper resizing.

    I kept everything at 720x480 and I'm using convertXtoDVD to make the dvd. I did not enable de-interlacing. I dunno.

    This has little to do with deinterlacing (you do not need to). I bet all your DVD players and TVs are behaving as expected, too. What jagabo meant was, somewhere between capture, editing, and burning to DVD, your field order got switched. It may be a bug, a setting, a default, that has to be changed, etc. What was top field became bottom, and vv. This is likely why you see combs. Without more excruciatingly explicit details about how you got from Hi8 to DVD, hard to say anything more.
    Stop feeling suicidal just because he unfriended you on fezbuk.

  5. Or maybe you encoded as progressive. Did I read that ConvertXToDVD always encodes as progressive? Got a sample?

    Hi8 is top field first, DV is (normally) bottom field first. As turk690 and others have said, field order has probably been mishandled in the conversions.

  7. Hi8 is neither top field first nor bottom field first. It's just an alternating sequence of top and bottom fields. When a DV device captures analog video it starts with a bottom field then adds the next field, a top field, to fill out the frame. That creates bottom field first frames. If you don't do anything that disturbs the field structure and encode as interlaced BFF for DVD they will play back properly on TV.

    Wavy vertical edges may indicate the frame was resized vertically without interlaced handling. For example, the software may have cropped 10 lines of head switching noise off the bottom of the frame and resized what was left to the original frame size. The size of the waves will vary depending on the amount of that was cropped:

    Download Mpg2Cut2 and extract a few seconds from one of your VOB files (Mark-in, Mark-out, File -> Save This Clip). Upload it here.

    A few seconds of your DV source might be helpful for comparison too.

  9. Sure.. I'll get the samples as soon as I find time. In the meantime, i'm trying another nice freeware called dvd flick that takes lots of source video files and makes them a DVD.

    My guess is your problem will disappear. AvsToDVD is better, though.

    I tried DVD flick but unfortunately it has the same results as convertxtodvd, and do you guys think maybe fitting 2 hours into a 4.7GB dvd is too much? I see a lot of encoding artifact.

  12. You encoded it as progressive. You may not be able to encode as interlaced in ConvertXToDVD, but you can set DVDFlick to encode interlaced. Instead of choosing NTSC-Film, choose NTSC. Or use the better AVSToDVD.

    Well thats weird, I didn't choose NTSC film to begin with. I chose just NTSC. Using NTSC film wouldn't it screw up the frame rate at 24fps?

  14. I'm going to try avstodvd.. it definitely looks like it has more options.

  15. avstodvd looks like it's doing it right. The resultant VOBs are interlaced.. however when I play it on my blue ray player on a plasma display, it looks like it's de-interlacing it and it's almost 'movie like' on motion now. I'm guessing the player is doing it. I'll do some more testing when I get the time. Thanks!
