    Over the years I have taken some shot videos with various Kodak point and shoot cameras. Some of this stuff is important to me, but tends to get forgotten out in a folder somewhere on my hard drive. I'm also in the process of converting my old VHS-C video to DVD. I thought I might be nice to mix the MOV videos with the VHS-C ones.

    I've been using a Canopus ADVC110 for the VHS-C conversion, so most of that is in DV format. I'm also using Vegas Movie Studio 9 for my edits. Dragging the MOV files to the time line works fine, but viewing the MOV on a TV looks pretty bad.

    I'm been playing around with AviSynth to see if I can do a better job there. I'm also going to want to end up placing subtitles containing the date on these MOV files as my VHS-C is already that way. Thought that AviSynth could save me a few steps...or am I better off just staying with Movie Studio. I know this will never look great.

    I'm in the US.

    Here's a stub of what I have so far:

    QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    #Convolution3d(0, 32, 128, 16, 64, 10, 0)
    LanczosResize(720, 480)
    ConvertFPS(30)
    AssumeTFF()
    #AssumeFPS(30)
    SeparateFields()
    #SelectEvery(12, 0, 1, 2, 3, 4, 7, 6, 9, 8, 11) #pick 10 fields out of 12
    SelectEvery(4,0,3)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)
    I'm still a bit foggy on a lot of this--especially the frame rate conversion. Any help would be appreciated.
    Thanks

  2. It looks like your source videos were 15fps , and you are trying to integrate this into your project by making it 60i (to match the rest of the DV) - which isn't going to give you good results because there are 4x the temporal samples in DV compared to the camera mov clips.

    In your script you have to make it 60fps (not 30) , before you re-interlace it; the way you have it now won't be DVD compliant. So ConvertFPS(60000,1001) - (it's actually ~59.94 fps, not 60fps; "60fps" is just a simple way of saying it)

    The basic approaches for frame rate conversions are a) frame duplication b) frame duplication with blending c) frame interpolation (generate new frames) . They all have significant drawbacks. a+b will studder with blurring, c will be cpu intensive and generate new artifacts but will be smoother for playback. ConvertFPS will dupe+ blend.

    Also if you want to make it BFF (to match the DV footage, assuming that is BFF), you can use SelectEvery(4,1,2) instead

    (not to mention the low resolution and probably quality of the source clips...)

    Thanks poisondeathray, I know the quaiity is going to be bad. I'm just trying to to make is less bad.

    MSU_FRC seems to help quite a bit.

    Code:
    Subtitle("Test", QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    AssumeTFF()
    MSU_FRC(4, "slow")
    #Convolution3d(0, 32, 128, 16, 64, 10, 0)
    #ConvertFPS(60)
    #StackHorizontal(x,y)
    LanczosResize(720, 480)
    SeparateFields()
    SelectEvery(4,0,3)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)
    Quote Quote  
  4. MSU_FRC is an example of (c) or frame interpolation . In avisynth, the comparable filters would be mflowfps or mvflowfps (from mvtools2 and mvtools) . On some content, mflowfps is better, on others MSU_FRC is better. You can mix+match frames if you're very picky. YMMV

    (Note I edited my above post to include BFF field order information)

    You should add AssumeFPS(60000,1001) after the MSU_FRC line, because your frame rate won't quite be exact after MSU_FRC

    Thanks again, yes I just spotted you edits. Stuff I needed to know. Thanks!

    Code:
    QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    AssumeBFF()
    MSU_FRC(4, "slow")
    ConvertFPS(60000,1001)
    #StackHorizontal(x,y)
    LanczosResize(720, 480)
     #Convolution3d(0, 32, 128, 16, 64, 10, 0)
    SeparateFields()
    SelectEvery(4,1,2)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)

  6. It should read AssumeTFF if you want it converted to BFF with SelectEvery(4,1,2) .

    Code:
    QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    MSU_FRC(4, "slow")
    ConvertFPS(60000,1001)
    #StackHorizontal(x,y)
    LanczosResize(720, 480)
     #Convolution3d(0, 32, 128, 16, 64, 10, 0)
    AssumeTFF
    SeparateFields()
    SelectEvery(4,1,2)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)
    If you want a better upscaler (but slower to process), you can look into NNEDI2

    It will produce less aliasing than a straight lanczos resize.

    Often after upscaling, a light sharpen is helpful as well

    Thanks for the corrections poisondeathray, looks like I wasn't scaling correctly either. I added an "AddBorders".

    What do you recommend for sharpening? I was over doing it with ff3dfilter.

    Code:
    QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    AssumeTFF()
    MSU_FRC(4, "slow")
    ConvertFPS(60000,1001)
    nnedi2_rpow2(rfactor=2)
    AddBorders(50,0,50,0)
    #fft3dfilter(sigma=1.5, bt=5, bw=32, bh=32, ow=16, oh=16, sharpen=0.4)
    
    SeparateFields()
    SelectEvery(4,1,2)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)

  8. I'm assuming you don't want borders?

    Since your clips are 320x240 to begin with , you have to scale past 2x , and back down (NNEDI2 only goes in multiples of 2, so the next one would be rfactor=4)

    nnedi2_rpow2(qual=3,rfactor=4,cshift="spline36resi ze",fwidth=720,fheight=480)

    I would try LimitedSharpenFaster, or LSFMod and adjust the strength to your tastes , but to be honest, with low quality sources , it probably won't make a huge difference. You will get less ringing with those compared to the sharpen in fft3dfilter

    As with everything , all these filters and settings are very source dependent, so play with them until you find something you like

    Thanks again poisondeathray. I don't really want borders, but it's more important to me to have everything scaled correctly.

    I tried some of you recommendations. As you suspected, they didn't make much difference.

    Here's my "final", if I understood everything correctly...

    Code:
    LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\nnedi2.dll")
    QTInput("UTC 2004-01-01 170128.mov", color=2, audio=true)
    ConvertToYV12()
    AssumeTFF()
    MSU_FRC(4, "slow")
    ConvertFPS(60000,1001)
    nnedi2_rpow2(rfactor=2)
    DegrainMedian(limitY=5,limitUV=5,mode=3)
    AddBorders(40,0,40,0)
    SeparateFields()
    SelectEvery(4,1,2)
    Weave()
    Subtitle("Test", align=1, text_color=$ffffff, size=18, last_frame=90, x=48, y=432)
    Thanks for you help.

    But if you are doing this for DVD, I think the 4:3 flag will throw your AR off if you add borders. Your original footages was 320x240 (assuming square pixel, that's a DAR of 4:3) - you're not encoding a square 1:1 pixel DVD

    Think of it this way, when you just did the normal lanczos resize to 720x480, you encoded a 4:3 DVD normally and it looked fine, correct? It's the same thing with NNEDI2 upscaling, the AR is unchanged because you scale w,h in multiples of 2.

    I hadn't actually encoded anything yet. Last night I encoded four different versions, and viewed on my television. You were absolutely correct. Thanks for taking the time to look at this. You saved me from making a big mess of everything.

    Code:
    LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\nnedi2.dll")

  12. but you're probably going to want to remove the "info()" line before you actually encode

    it's always good practice IMO to do a small test encode first, just to test the waters and see if it's going to turn out ok, before potentially wasting time on a long encode

    Yeah, I actually encoded it in during testing. It helped me keep track of my various samples.

    Good advise! Thanks

    Ok I'm stuck with a silly question. Now that I know how to convert and clean these videos, what's the best way to save them to a file? I used HC Encode for my testing and it worked great, but since I'm doing my edits in Vegas Movie Studio and the rest of my video is in DV... What's recommended? I could use VirtualDub. Would that do any color space conversions?

    For my DV captures (from VHS via ADVC110), I usually do my edits in Studio, save as DV (1 hr segments, no reencoding), then author in DVD Architect--letting DA do the encoding with a 9000 bit rate. Since I keep the edited DV for archive, it seems that I'd want the MOV video also in DV so Studio wouldn't need to reencode these either and I could save as one 1 hour DV clip with both the VHS and MOV parts...

    ???

    did you want to save them to a DV-AVI then import into vegas movie studio?

    If you use vdub and do all the filtering in avs scripts, you can use "fast recompress mode", which avoids YV12=>RGB colorspace conversion.

    Usually footage out of vdub has to interpreted in the editor, or authoring application (aspect ratio 4:3 instead of 1:1 which vdub and avisynth assume)

    Note only cuts type editing will pass through without re-encoding in your editor, if you do global changes like color correction, filters etc.... it will still re-encode. In that case it might be better to use a lossless intermediate like huffyuv or ut video codec for all your intermediate steps (even when exporting from vdub)

    I was thinking I wanted to save as DV-AVI for import into Movie Studio. Generally I just do strait cuts in Movie Studio, but perhaps I'll give a lossless codec a try. Can't hurt.

    I was thinking I could do the "fast recompress mode" in VD. Thanks for the confirmation.

    Sounds like it time for me to stop screwing around and get my last three VHS-C tapes done!

    Thank you!

    I was working my way through my MOV files, until I got to the point were I had bought another camera. Frames are not 15 fps anymore but now are 23.954 fps.

    Can I just change this:

    Code:
    MSU_FRC(4, "slow")
    ConvertFPS(60000,1001)
    to this?

    Code:
    MSU_FRC(2, "slow")
    ConvertFPS(60000,1001)
    Is there a better way?

  18. As suggested above, I would use mflowfps. Results are generally better than MSU's plugin on most types of material (less artifacting). If there is too much artifacting, you can add a bit of motion blur. You can look at the documentation for more examples and tweaking parameters. Make sure you use a frame accurate source filter (ie. not directshowsource)

    Code:
     
    #SourceFilter()
    super = MSuper(pel=2)
    backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
    forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
    MFlowFps(super, backward_vec, forward_vec, num=60000, den=1001)
    That will give you 60000/1001 ~59.94 fps

    Sorry, I have a couple more questions. I've updated my script as below. I'm using VirtualDub to save to a AVI file before processing via AVSTODVD.

    If I save to DV, all is well except my display aspect ratio is 3:2 instead of 4:3.

    If I save to HuffyUV or Lagarith, ratio is still 3:2, and isn't marked as interlaced anymore.

    How can I fix the display aspect ratio?

    What going on with interlacing on HuffUV and Lagarith?


    Code:
    LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\nnedi2.dll")
    LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mvtools2.dll")
    v=QTInput("c:\video\in\2005\save\2005-02-06 132312.mov", color=2, audio=true)
    m=v.GetChannel(1).ResampleAudio(48000)
    s=mergechannels(m,m)
    AudioDub(v,s)
    ConvertToYV12()
    AssumeTFF()
    #MSU_FRC(4, "slow")
    super = MSuper(pel=2)
    backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
    forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
    MFlowFps(super, backward_vec, forward_vec, num=60000, den=1001)
    #ConvertFPS(60000,1001)
    nnedi2_rpow2(qual=3,rfactor=4,cshift="spline36resize",fwidth=720,fheight=480)
    #DegrainMedian(limitY=5,limitUV=5,mode=3)
    SeparateFields()
    SelectEvery(4,1,2)
    Weave()

  21. everything should be fine when you encode to MPEG2 and/or author it - the 16:9 flag is set then, and you encode as interlaced. vdub and avisynth work with square pixel 1:1, so a 720x480 frame size will give a DAR of 1.5 (or 3:2) as expected

    mediainfo just reads the flag in either the header or stream. It's often incorrect, because the actual content is interlaced. Progressive content can be flagged as interlaced and vice-versa. It's the actual content that matters (and what you do with it after).

    also , I think your "subtitle" should be placed before it's reinterlaced (before the separatefields line) - what is it exactly?

    try it out, and check out the final export. If it isn't ok, then report back

    Thanks again. I thought all was ok, and my previous test burns looked good.

    I think AVSTODVD must be reading the same headers, and isn't generating the default AviSynth script the way I'd like--offering the add borders, resize, and deinterlace.

  23. ^I made some edits above in my post, I think you should change your subtitle placement (the order in the script), because the way you have it now it's overlayed on top of the interlaced video, not overlayed on the progressive video then interlaced

    There must be some options to disable that stuff (like borders, resize) in avstodvd? (I'm not too familiar with it)

    Otherwise, you could encode using HCEnc instead ; you will get exactly what your script indicates. (just preview your .avs script in vdub or avsp)

    Also note, HCEnc accepts .avs scripts directly. So it's not necessary to use intermediate like huffyuv. (Although if you are using a 2pass encode with heavy filters in the script it may still be faster to do it that way)

    Since the subtitle is static, it shouldn't make any difference.

    Seems to work ok either way, from what I can see. I was assuming that subtitle was "interlaced aware".

    Also note, HCEnc accepts .avs scripts directly. So it's not necessary to use intermediate like huffyuv. (Although if you are using a 2pass encode with heavy filters in the script it may still be faster to do it that way)
    Yes, I've decided to write a batch files to batch convert them. Seems to be working well. HCENC has a -lossless option that may help on multiple passes...

    Thank you poisondeathray and Gavino!

    PS - Does it make a difference if you do the frame interpolation or resizing first?

    It's not so much "interlaced-aware", more like "interlaced-neutral".
    Since the subtitle is the same on all affected frames, subtitle+interlace gives the same result as interlace+subtitle. (This would not be true for a scrolling title, for example.)
    Does it make a difference if you do the frame interpolation or resizing first?
    Since resizing introduces less artifacts than frame interpolation, I would expect slightly better results with resizing first, although it will probably be slower. Try it both ways with a short sample.
