MPEG Streamclip Scan mode, interlaced or progressive?

As a follow-up to my previous question, I see under Options there are 2 possibilities, interlaced or progressive. Which should I use please? Keith

Thank you Tom. It's wonderful to have you "there" to answer these questions. It's all a bit of a mystery to me still!

  • Scan mode when exporting - progressive or interlaced?

    This may be a dumb question but I did a search and couldn't find anything definitive.
    I have large uncompressed quicktime files that I need to export with the DVCPRO codec down to a file I can then use.
    What's better to use as far as the scan mode? Progressive or Interlaced? And what's the difference between the two?
    Any insight into this matter would be really helpful.

    In layman's terms...
    Film is Progressive.
    TV is Interlaced.
    Computer monitors do not show interlaced material in its true form... that is with a 'gun' zooming down the screen showing one field and back up the screen showing the other 60 times a second, as in a TV.
    If you really want to see what progressive material will look like you need a progressive monitor. If you really want to see what interlaced will look like you need an interlacing monitor (broad generalization, but kind of true... I mean, you can get a good idea what progressive will 'look' like on an interlacing monitor, but you won't get a good idea what interlaced will look like on a PROGRESSIVE monitor).
    SO...
    What YOU really need to decide is 1) what type of LOOK you are going for... smooth 'reality' look of interlaced, or film-ish look of progressive, and 2) where you will be presenting this work... if it is for the web, realize that 90% of the monitors will be progressive in nature.
    Don't be AFRAID of interlaced material... just use it for what it was intended for use with... er... in which it was intended to be used... er... well, you should get my point by now.
    Good luck,

  • Deinterlaced playback of MPEG Streamclip MPEG2 output with QT Player Pro

    SOmetimes I use MPEG Streamclip to convert my DVD video to a file using the "MPEG2 with MP2 audio" option.
    QT Player Pro plays these back fine except it refuses to deinterlace, even if I select the deinterlace option in the QT Movie Properties window, and even if I resave the file with deinterlace selected.
    VLC deinterlaces the video even if I have deinterlacing deselected. DVD player deinterlaces the DVD video fine but won't open the stand-alone MPEG2 files.
    Is there anything I'm missing? Is there a way to get QT Player Pro to deinterlace playback of MPEG2 without converting to a different format?
    Thanks!

    Is there anything I'm missing? Is there a way to get QT Player Pro to deinterlace playback of MPEG2 without converting to a different format?
    Not sure which specific settings you may be using. Therefore, here are some comments/peculiarities of which you should be aware when using interlace/deinterlace/MPEG2 settings:
    Interlaced Scaling
    If you are scaling an interlaced file to a different height, you can tell MPEG Streamclip to preserve interlacement and scale each video field separately by checking "Interlaced Scaling". If you don't, interlacement will be lost in the scaled movie, and, worse, you will get many visual artifacts. This setting is now enabled by default; remember to disable it with progressive files.
    Interlacement requires a frame height of more than 288 pixels. If the frame height of the source file is up to 288, interlaced scaling will not be enabled. If the frame height you have chosen for the exported movie is up to 288 and you check "Interlaced Scaling", MPEG Streamclip discards the lower field before scaling the picture (i.e. it performs a fast deinterlacing by dropping one field).
    Reinterlace Chroma
    If you are converting an interlaced MPEG-1/MPEG-2 file, you may wish to "reinterlace" chroma. By checking "Reinterlace Chroma" you can enable a special remapping of 4:2:0 chroma lines so they will be split correctly between the two video fields. This is a very advanced option: only professional users may see the difference in the output movie. This option is enabled by default; disable it when you are sure your file is not interlaced.
    This option has no effect if the source stream is not an MPEG-1/MPEG-2 stream.
    Deinterlace Video
    If you have an interlaced file, you may also want to deinterlace it, usually to convert into a progressive format, get a "film" effect and have a better playback on the computer's display. When you check the option "Deinterlace Video", MPEG Streamclip enables a special motion-adaptive deinterlacer, and it deinterlaces the lower field in the parts that contain motion, and preserves video quality of all parts that do not contain motion; the upper field is left unchanged. This option slows down the conversion.
    Please note that if you are changing the height of an interlaced stream (that is, you are telling MPEG Streamclip to perform vertical scaling) then you must enable either "Interlaced Scaling" or "Deinterlace Video" (at your own choice), otherwise you will see bad video artifacts in the converted movie.
    Not sure this will be of any real benefit in your case, but thought I should point it out for your consideration and see how it applies to your particular work flow.

  • MPEG StreamClip & Progressive Setting

    So using Streamclip to convert stuff to my iPhone and also my PS3. The option for De interlacing and progressive scan is confusing. More importantly you are not supposed to use one if you already are dealing with progressive material. so my question...
    How can I tell if my source material is progressive or not? What programs will say a specific DVD or MPEG file is one or the other?

    Thank you Tom. It's wonderful to have you "there" to answer these questions. It's all a bit of a mystery to me still!

  • Progressive Scan mode (DVD on Sharp Aquos LCD)

    I want to use the Mac Mini as a DVD player on my 32" Sharp Aquos. Does anyone know if the Mac Mini supports progressive scan mode?
    Also, has anyone run into issues connecting to the 32" Sharp Aquos LCD TV?
    Thanks
    Curt

    Along the lines of progressive scan vs. interlaced... I've noticed while playing video from Quicktime I can make a selection to pick which one I prefer. I've got a project that I created in iMovie and I notice that if I were to share (export) a clip using the expert settings I can chose whether it is interlaced or progressive. However, when accessing those same .mov files in iDVD I don't see any settings that indicate whether the final DVD will be interlaced or progressive. From the looks of the footage viewing it on my computer it looks like it is interlaced. How can I create a DVD with this iMovie footage that ends up displaying as progressive?
    thanks for any advice.

  • Why does De-interlacing looks better with MPEG StreamClip?

    For our client we need to render 1080i for TV and 1080p for WEB. After creating graphics in AE we add final touch and audio in PR.
    If we make it progressive in PR (CC2014.1) the zoom in the packshot does not look good.
    However if we make the 1080i ProRes progressive in MPEG Streamclip the zoom does look great.
    How is it possible a freeware swiss army-knife makes a better progressive export than commercial software?
    Or is there something we do wrong?

    Qt does 4 or 5 passes you just don't see it happening...Compressor does 4 or 5 passes...
    Had wondered in the past but you are the first person to confirm this.
    I've seen it when a h.264 is set to multi-passes and the video doesn't has much going on in it...then there is fast encoding...
    Always happens in H.264 and is specifically mentioned in the Help file. Would prefer, however, that instead of simply saying "Passing movie at ..." the progress window would say something like "Pass #1: movie at ..." and increment the pass number on each pass so I will know when to expect the last pass. Got into the habit of always monitoring the last pass to scan the video output and keep an eye on the combined average data rate. However, must admit this may no longer be necessary as the data rate appears more stable (i.e., not as "loose" as v1.7) and output is actually iPod compatible.
    I've seen it when a h.264 is set to multi-passes and the video doesn't has much going on in it...then there is fast encoding...
    Am trying to consolidate workflow to fewer applications rather than expand them. Was forced to use MPEG Streamclip to create consistently cropped/scaled video frames for media sourced from old TV footage. Was totally dissatisfied with ffmpegX in this department and fell back on the old MPEG Streamclip to new QT workflow as the best temporary alternative. And, since there is little visual difference between the single-pass and multi-pass modes, the new Streamclip also provide a much faster workfolw for material that is basically dated and of a somewhat lesser quality to begin with.
    Or to take a 10-bit uncompress and make it either smaller x to y or change the frame rate...Or take a 10-bit from FCP flatten the transitions and then bring that back into FCp...
    Have to confess that my efforts are only directed exclussively towards personal archiving and easy access of so-called "oldies but goodies" and not "production level" edits.
    Do you think Streamclip does a good job on h.264? Compared to Qt...
    If pressed, would have to admit that I probably like the "tweeking" done by Apple for quality. MPEG Streamclip, at least using my combination of workflow, filters and settings, produces a somewhat "softer" rendering than I prefer. This is likely due to my using the "wider 2D-FIR" scaler and undoubted contributes to increased processing times since I crop/scale in both horizontal and vertical dimensions. Would, however, readily change my workflow if Apple were to add the ability to control alternate audio tracks to both the iTunes application and iPod firmware, as well as, provide AC3 support for QT-to-Optical line output. (This is rapidly becoming a personal "pet peeve" as we approach release of the "iTV" device in Q1 of next year.)

  • What setting in "MPEG STREAMCLIP"?

    Hi,
    I have a Sony V3 camera and using "MPEG Streamclip". I would like to know what are the best settings for converting my movie clips for use in iMovie. Also, I am pretty new to this so can anyone tell me what the Apple MPEG2 Playback Componant does and do I need it to help with my Sony movie conversion?
    Thanks ahead of time...
    Thomas

    Export your clips in DV format from MPEG Streamclip. There are two options on the right side of the export screen for non-interlaced or progressive scan video. Uncheck those as suggested on the screen - the video from your camera is not interlaced.
    You need the MPEG2 Playback component if your movie is in MPEG-2 format. You need it if you want to convert video clips from a DVD, including DVDs created with a DVD camcorder.

  • Can someone explain Scan mode to me?

    I'm just looking for a little help. I have just taken a production coordinator role and part of my job is to export broadcast quality movies as well as send different formats to clients to check. Today my boss told me to export a clip in DV Pal and make it "progressive". So, in the options I found the scan mode drop down had a choice of "interlaced" or "progressive" and I therefore chose the latter.
    I just wondered what the reason was for choosing "progressive" over "Interlaced"?
    I know this probably sounds like a dumb question to a lot of you, but my boss is not the most helpful, informative of men so I am kind of trying to learn as I go.
    So, if anyone can offer any advice regarding this or even tips about codecs and exporting, that'd be really great.
    Many thanks.

    Think of every horizontal line of pixels on your screen as a different line.
    Progressive: scans one line at a time moving downwards
    Interlaced: scans every odd line moving downwards, then every even line moving downwards.
    Pretty much progressive provides a better picture, but interlaced can raise the framerate. The problem with interlaces is that videos can end up looking ugly and stripe-y.
    If this doesn't make sense, maybe this video can help:

  • MPEG Streamclip 1.5

    MPEG Streamclip is a high-quality converter for MPEG files and transport streams.
    MPEG2 conversions require the $20 Apple MPEG-2 Playback Component.

    http://www.apple.com/quicktime/mpeg2/
    New in this version:
    - The new files that can be played, edited and exported are: MOV, DV, AVI, DivX, MP4; to open DivX files you have to install either the DivX codec, or the 3ivx codec, or the XviD codec. You can also open WMV files, if you buy Flip4Mac's WMV Player.
    - You can set the 4:3 or 16:9 flag for DV export (useful for iMovie HD).
    - You can export in ISO MPEG4 (MP4) format. You can use the H.264 codec, if you have QuickTime 7.
    - Built-in "Save as AVI" feature.
    - You can change the frame rate of the exported file, with optional frame blending.
    - QuickTime 7-style AIF files are recognized.
    - While in full screen mode, you can zoom the picture with the up/down arrow keys.

    1.5.1b1 is out
    Oh, great!
    Just after I sent a report about the bug in two-pass encoding it was already solved!
    BTW, now MPEG Streamclip 1.5 can convert also DV material 4:3 <-> 16:9 while preserving interlacing! It can do the conversion with letterboxing or without letterboxing (but with cropping, of course).
    For more details, check:

    iMovie HD deinterlaces while doing its own 4:3 <-> 16:9 conversion and the colors are washed-out -- MPEG Streamclip does all this with good quality!
    I wonder why Apple hasn't hired the MPEG Streamclip author. But, on the other hand, a corporate management could ruin all this...

  • DV Export Settings: Scan Mode in iMovie HD

    Could some one please tell me the purpose of the Scan Mode under the DV Export Settings?
    I wanted to export some clips so I could bring them into Final Cut Pro. I went File>Share>Quicktime>Expert>Share>Export Movie to DV Stream>Options and saw that the scan mode had the option of progressive. Does that mean I can change from interlaced to progressive? Or does that need to be set to what you imported?

  • JVC GZ-HD7U MPEG Streamclip export settings for use with FCP

    There are a number of compression options in the free MPEG Streamclip 1.9.2 and it's unclear what's best or how I would figure that info out. My guess is Apple HDV 1080i50, Apple HDV 1080i60, Apple DVCPRO HD 1080i50, or Apple DVCPRO HD 1080i60. The default setting was Apple Motion JPEG A, but this produced a huge file and doesn't seem right anyway. I think the desired frame size is 1920 x 1080, but I'm uncertain if I need to end up with an interlaced or progressive .mov file. My selectable options for progressive/interlaced are: "Interlaced Scaling," "Reinterlace Chroma," and "Deinterlace Video." Selecting "Deinterlace Video" excludes use of the other two options.
    These clips will eventually be edited in FCP and I'm guessing that the appropriate settings will match whatever is selected at the export stage.
    I'm using the JVC Everio GZ-DH7U HD Hard disk camcorder...I'm not sure if JVC uses the same setting across the board for it's HD cameras or maybe just the Everio cameras are similarly designed??
    Thanks to all!!

    the output should match the source file, generally speaking. So if you camera is making HD files then using a HD sized coded would suffice.
    HDV (IIRC) is 1440x1080. I often find that using the default settings for a particular file type in Streamclip often work quite well.
    As a test, take a small file. if it works, great batch process away, if not, tweak it and then try the same small file until you get a desirable result. Rinse and repeat.

  • MPEG1-DV conversion using MPEG Streamclip. Help!

    I am having problems converting an mpeg1 movie clip for editing in iMovie.
    I recently recorded a concert on my Sony DCR-HC40 camcorder. The majority of the concert was captured to cassette in DV-PAL format (720 x 576, stereo, 48 kHz at 25 FPS).
    However, the final third of the concert was captured on the camera's MemoryStick Duo in MPEG1 muxed format (320 x 320 at 25 FPS). The clip is 84 Mb in size.
    I want to convert the mpeg clip into the same format at the cassette footage so that I can seamlessly splice the two sets of footage in iMovieHD with as little depreciation in quality of image and sound as possible.
    So far I have simply used the 'export to DV' command from the File menu in MPEG Streamclip. But this produces a noticeably crackly-sounding depreciation in sound quality and no improvement in image quality - rather the reverse infact, since when viewed in the larger Quicktime window, the clip shows up the poorer resolution of the original clip.
    What do I need to do to get the original mpeg clip to as near a quality as the cassette footage, for editing and burning onto DVD for display on a TV?
    Any guidance would be much appreciated.
    BTW, I am running Tiger 10.4.3 on a Pb G4 (QuickTime 7.0.3/iMovie 5.0.2)
    PowerBook G4 17 1.5 ghz 512 MB Ram   Mac OS X (10.4.3)  

    mpeg1 footage is only fit for showing on screens no larger than an iPod photo or mobile device?
    MPEG1 is usually encoded with low resolution and rather low bitrates so the quality is often rather poor.
    However, MPEG1 CAN be encoded with DVD-like resolutions and bitrates so the quality CAN be quite good (MPEG1 doesn't support interlacing like MPEG2, though).
    It would be a shame to lose the footage as it was part of a concert of Handel's Messiah.
    One option could be to do minimal edits to the MPEG1 with MPEG editors like MPEG Streamclip and burn it as a VCD or DVD (they both CAN have the same video although DVDs rarely use it). Then you'd preserve ALL video quality there is.
    ...but this won't work with your 320x240 video because the VCD/DVD compatible resolution is PAL 352x288 or NTSC 352x240. So you'd need to re-compress even your 320x240 MPEG which degrades quality.
    So your best quality option is to watch the MPEG1 on a computer monitor via MPEG Streamclip, QT Player or some other viewer.
    Or, you can convert to DV and blend it with the high quality DV tape material. Converting MPEG to DV should not much or at all degrade quality because DV is a much higher quality codec than your MPEG1 source.
    Bit Rate: 0.73 Mbps
    Duration: 0:16:16
    Data Size: 84.79 MB
    That's quite low. A DVD uses about 4-6-8 Mb/s and a low quality low res VCD uses 1.1 Mb/s. So your MPEG1 quality can't be very good to begin with.
    Audio Tracks:
    192 MP2 mono, 32 kHz, 32 kbps
    That's very low, too. Even a low quality MP2 often uses 192 kb/s. And the 32 kHz must be resampled to 48 kHz for DV or DVD use.
    when played, either via streamclip before conversion, or in QT (I don't have QTPro) after conversion to DV, distorts at quite low levels in a way that a QT movie from cassette does not.
    I'm afraid that there is not much you can do if you hear the distortion even BEFORE any conversions. Some dedicated audio processing app might soften the distortion but I wouldn't count on that.
    FWIW, you might try to convert using the "Low Level" audio. From the MPEG Streamclip guide:
    "For MPEG audio tracks (MP1, MP2) two different audio levels are available for playback and conversion to MOV, DV, AVI, MP4 and AIFF: "High Level" and "Low Level". You can choose one of these two levels using the "Audio Mode" pop-up menu. The default level is "High Level". Use "Low Level" if, and only if, the converted movie or AIFF file shows an excess of volume."
    you also mention that re-compressing with iDVD will further degrade quality. Is this true of both types of footage (mpeg->DV & DV cassette)?
    MPEG2 compression used in video-DVDs will ALWAYS degrade quality. High quality material (such as DV) tolerates this better so you might not even notice it. So you should use high bitrates if you want to convert and burn the low quality MPEG1-converted-to-DV material as a DVD (with iDVD use Best Performance or don't exceed ~70 minutes with Best Quality).
    would I need to get Roxio Toast? What is the difference between this and IDVD?
    Toast 7 can be forced to burn non-valid DVD resolutions as a video-DVD (MPEG Streamclip can be used to prepare the MPEGs) with no re-converting or quality loss but those DVDs are not guaranteed to work on standalone DVD players so I'd not use that route.
    Basically, what I'd like to acheive is a nicely-edited home movie with titles etc, to put onto DVD & VHS, of a 2.5 hour classical concert, in as good a quality, audio/visually as I can, from the two types of footage, spliced as cleanly as possible. The footage is continuous, but the media changes from cassette to mpeg at a certain point.
    Don't exceed ~70-75 minutes with iDVD because after this the quality starts to drop. Toast 7 can burn somewhat longer high quality DVDs than iDVD because it uses compressed AC3 audio so it doesn't "steal" bandwidth from video as iDVD does with its uncompressed PCM audio. But compressing that low quality audio might not be a good idea either!

  • Interlace or Progressive when Authoring DVD's

    Hi,
    I'm wondering what I should set my Video Settings to:- Interlace or Progressive when creating Quicktime Movie Files, which I later intend to convert to Mpeg-2 for DVD authoring.
    I was told that since Most TV's only accepted Interlace, I should use Interlace. Is this True?
    Thanks in advance for your time.
    Regards,
    Rajnesh

    Thanks for your reply. Actually my footage is from an Image Sequence that was Scanned from a Film Negative. I used Graphic Converter (comes with the Mac) to convert to a Quicktime Movie.
    I recently tried it both ways - choosing 1. Progressive and 2.Interlaced. Both were then converted to MPeg-2 and viewed on a home TV. The Interlaced seemed better.
    But I was wondering how / whether I could use Progressive...

  • Best way to work with interlaced and progressive clips in the same timeline

    I´m shooting with Sony MC-50E camera in 1920x1080, 50i. When importing with Log & Transfer I can work with ProRes 422 files in interlaced mode. I have to mix the footage with video screencapture which is progressive (ProRes 422). The final videos are for web only so it should end up as progressive H264 videos. I´m getting good result if exporting to H264, 1024x576 with deinterlacing enabled, but exporting to full HD gives typical interlaced lines in the picture. How can I avoid this and what is the best solution for working with both interlaced and progressive clips?

    Deinterlace in Compressor using Frame Controls, Best settings. You can reconnect the deinterlaced files to your project, if you've already edited, but you may need to copy and paste the clips in your sequence to a new 25p timeline, then Remove Attributes, Basic Motion.
    When you're ready to export your sequence, use Quicktime Movie, Current Settings, Self-contained. Take that file to Compressor to transcode back to h.264.
    The Apple T.V. preset is very good.
