    Progressive DVD with Squeeze 8

    Has anybody figured out what settings to use in Squeeze 8 to produce a progressive DVD?

    Michael Phillips posted a preset on August 30, 2008, that works in Squeeze 5.  (I don't know about Squeeze 6 or 7, because I went straight from 5 to 8.)  It produced an MPEG-2 NTSC file, 23.976p with flags to tell DVD players to insert 2:3 pulldown if necessary.

    This useful feature appears to be broken or eliminated in Squeeze 8.  I am hoping someone out there can prove me wrong!

    Did you try this reply to your post in the Sorenson forum?

    NTSC DVD presets will make a 29.97 output. 29.97 is the framerate of NTSC format. If you want a 23.976 frame rate change the Format Constraints to "None" as well as changing the Format to "Unspecified"

    Re: Progressive DVD with Squeeze 8

    Hi Dom,

    I am using Encore CS5.5 to create the DVD, which worked fine with Squeeze 5.  When I set Format Constraints=None, and Format=Unspecified in Squeeze 8, Encore insists on transcoding the result.

    Have you created a Squeeze 8 preset that works for progressive DVDs?

    Re: Progressive DVD with Squeeze 8

    I think I pin pointed it to either Sorenson is not making a true progressive video or Encore is interpreting the field dominance incorrectly (lower).

    More investigation is needed, will compare both with other software.

    Re: Progressive DVD with Squeeze 8

    After hitting a dead end on this topic last month on the Sorenson forum, I attended a Sorenson webinar last week about using Squeeze 8 with Avid MC.  During the question session at the end, I asked the presenters to describe the workflow to produce a progressive DVD using Squeeze 8.  My ensuing e-mail discussion over the past week with helpful Sorenson presenter Randon Morford, yielded the following settings to do the job in Squeeze 8:

         Format Constraints = DVD (MPEG 2)

         Stream Type = Elementary

         Codec = MPEG-2 Video

         Format = NTSC

         Frame Rate = 29.97

         Field Encoding = Bottom Field First (Progressive resulted in an error.)

    Dropping the compressed video file produced by Squeeze into MediaInfo shows the following characteristics:

         Frame rate = 23.976

         Scan type = Progressive

         Scan order = 2:3 Pulldown,

    which Randon confirmed to mean it is progressive with pulldown flags.

    Back in business with Squeeze 8!

    P.S. Forgot to mention that this only works if the video that you input to Squeeze is 23.976p to begin with.  If you input a 59.94i video instead, you will get a 59.94i result.

    Can someone chime in on the pros/cons of creating progressive DVD's and BD's?  Thanks much!

    Re: Progressive DVD with Squeeze 8

    Progressive DVD's squeeze fewer frames into the same bandwidth, theoretically giving your more info in your images. I always prefer to do 23.976 progressive when possible. Glad to hear there's a way to do it in Sorenson, 'cause I was ready to give up.

    conleec:

    Completely untrue, Chris.  The number of frames per second is the same regardless of whether you're dealing with progressive or interlaced media.

    What does happen is if you've converted interlaced media to progressive you've lowered the vertical resolution.  This happens because you drop one field entirely and interpolate it from the remaining, half vertical resolution media.  This can make the compression process simpler, albeit at the cost of somewhat reduced vertical resolution.

    With true progressive-originated media the loss of vertical resolution doesn't occur.  There may also be an improvement in perceived quality, since you'll possibly get fewer artifacts with non-interlaced media.  This effect (if any) will very much be dependent on the motion content of the original media.

    Media running at 23.976 is a special case.  By its very nature it's usually already a progressive format, and is made up of mixtures of two- and three-field frames.  Every three-field frame has one field duplicated, so with this scenario you will have 12 redundant fields per second.  When encoding to DVD it's possible to drop those redundant fields and gain effective bandwidth.

    But this is a special case.  25 fps and nominal 30 fps media will not be able to take advantage of the six "free" frame (12 field) advantage.  And arguably they may end up with marginally better or marginally worse performance, depending on how the progressive media was created.

    Re: Progressive DVD with Squeeze 8

    Forgot to mention that this new Squeeze 8 method only works if the video that you input to Squeeze is 23.976p to begin with.  If you input a 59.94i video instead, you will get a 59.94i result.  (I've also appended this comment to my earlier post.)

    My personal bias is that natively-shot progressive looks better than interlaced video.  I don't like the comb-like artifacts that you get with interlaced.  Plus with progressive you can edit in DNxHD-36.  And if you are shooting 1080p for Blu-ray distribution, then 23.976p looks like the way to go, because the Blu-ray 1080p standards do not include a 29.97p or 30p option (according to Wikipedia).

    Re: Progressive DVD with Squeeze 8

    I know this is an old thread, but I am thankful for this info.  I watched the Avid to Sorenson Webinar after the fact and didn't get the quesitons.  I am moving over from FCP / Compressor / DVD Studio Pro to Avid / Squeeze / DVD Studio Pro

    So this is the best way to get 23.976p footage on a DVD? (re: steps above from the Q+A Webinar)

    In my old workflow, Compressor indicated it was passing through my HD 23.976 footage at the same frame rate to SD Mpeg2 for the DVD, which I was then loading into DVD studio Pro.  I thought I would do the same with squeeze, but they only give you the 29.97 option.

    I was asking how to do this on Sorenson forums with not much luck.  Would love for you to weigh in and help me understand what the difference is between the 23.97 passthrough Compressor does to the instructions with Squeeze 8 above, and most importantly, the impact on the end quality of the DVD
