The Basic Functions of MPEG Streamclip (Mac Only)

MPEG Streamclip

Squared 5 has given both Mac and Windows users a great tool to use when it comes to multimedia files. MacHouse recommends every Mac user to grab a copy of their freeware, MPEG Streamclip. As of August 5, the current version of MPEG Streamclip for Mac is 1.7 and is in Universal Binary. 

MPEG Streamclip is quite a powerful application although the size of the latest version is merely 2.4 MB. It can be used to change video containers among AVI, MOV and MP4. And MPEG Streamclip accesses QuickTime components to perform video compression, which means you wouldn’t need QuickTime Pro to compress video with QuickTime codecs. But when you work on VOB files, whether you used QuickTime Pro or MPEG Streamclip, you must have Apple’s QuickTime MPEG-2 component, which is not free. 

Please note that we used Version 1.5.1 for Mac to make this VTC (1.0). But concerning the functions that are covered in this VTC, the difference between 1.5.1 and 1.7.1 is negligible to those who actually use MPEG Streamclip 1.7.1.

  • This VTC version: 1.0
  • Length: 5 minutes 19 seconds
  • Video format: QuickTime
  • Video compression: H.264
  • Pixel size: 720 x 540
  • Audio: None

      I think your right.

      But what I found out was if U open the AC3 file in QT it will play it as a 2.0 not a 5.1. The same is for iTunes. But I think that QT have to play 5.1 soon because of the iTV, people want 5.1 when they are using iTV.

      Is the film you can bye at iTunes store in 5.1?

      I got MPEG Streamclip to make the H.264 file with 5.1 and 2.0 in one file so when QT and iTunes is ready my file is also ready for 5.1.

      What a great program 🙂

      I now think I know what’s causing the problem. You don’t have MPEG-2 Playback component installed, do you? In order to process MPEG-2 video including SVCD and VOB with QuickTime Pro and MPEG MPEG Streamclip, you must have MPEG-2 Playback component.

      snip…The DVD is has a good picture until the plays starts and players are moving on the screen. I am really new at all this and have appreicated your web site to help me out. Thanks Coach

      I think the observation you see is the result of not enough information being picked up by the camera. I know the Cannon 100 writes an MPEG2 file to the miniDVD at a variable bit rate(VBR). This saves on battery and disc space. If there is no motion there a base rate; increase motion and you increase the data rate. But there is a Max rate for the miniDVD medium that is about a third of the rate for a miniDV.

      For editing and this reason the tape based systems offer more options and capture characteristics.

      I see. Since we don’t own a video camera, we wouldn’t know. Thanks for an insight.

      Great site, program.

      I am trying to convert an AVI movie file with AC3 sound to mpeg4 to play on a normal dvd player.
      I have figured out a rather long way that seems to work but hope you may suggest a better method. (I am new to this caper but am very impressed by both your program and ffmpegX)

      Currently i use ffmpegX to convert the file to a ‘MPEG-TS’ file, then use MPEG Streamclip to convert that file to a ‘MPEG with MP2 audio’ file.
      Then i burn with toast 6 and it seems to work.

      Can you tell me if this is the best way of doing this. I am after a quicker method but would like the best possible quality.

      I have a:
      emac G4 1.42Ghz
      1 GB ddr SDRAM
      OS X 10.4.8
      (I have not yet got mpeg-2 codec from Apple but would if it will help)
      MPEG Steamclip 1.7
      ffmpegX 0.0.9w r5

      Any help much appreciated.

      Thanks for your question.

      (1) MacHouse did not develope MPEG Streamclip. It’s done by Squared 5.

      (1) Since ffmpegX can handle AC3, why not using it directly to convert your AVI file into MPEG/DVD?

      Thank you for your very helpful site!

      Can you please advise me on what settings to use with MPEG-streamclip to convert MPEG 2 files to files that can be imported into Final Cut Pro 4. I’ve been trying to use it bu converting them to QuickTime, but the edited videos play well on the computer monitors, but when burned to a DVD using iDVD on a TV monitor, scenes with moderate motion are very “jumpy.” I’v etried playing with filed dominace settings alittle but haven’t found the solution.

      Can you offer any advice on how I can convert the MPEG 2 files to QuickTime so I can edit them in FCP in a way that I will not have bad motion when the video is played on TV?

      I’m using MPEG-Steamclip 1.7, FCP 4, on a Power Mac Dual 2.5 GHz PowerMac G5
      Many thanks, Larry

      >Can you please advise me on what settings to use with MPEG-streamclip to convert MPEG >2 files to files that can be imported into Final Cut Pro 4

      Sure. But my initial questions are

      (1) how you compressed MPEG-2 with MPEG Streamclip – DV25?
      (2) how you are exporting the final work with FC4?
      (3) Could you define what jumpy motion is in more detail? Does that happen if you play it with Apple’s DVD Player and/or VLC?

      I’m using MPEGStream Clip 1.7 (plus Apple mpeg2 component) on my Mac OSX (tiger) to convert several some vob files to DV to import them on iMovie.
      (I want to use iMovie to create a unique dvd by “merging/editing” some mini dvd (the vob files) created with my Sony DVDCam)

      In StreamClip->preferences I selected “Fix stream with data breaks”, and just before converting I run “Fix timebreask”, then I use “Export to DV” using DV(“%) as conversion option.
      When conversion is finished, the resulting dv after some minutes, is affected by A/V sync problem.
      I tried o ue also DVCPRO conversion.

      Are there other strategies to overcome this issue?
      Why DV conversion is causing a/v synch problem?

      I experienced same problems with ffmpegX.

      These are some info about one of my vob:

      Video Tracks:
      224 MPEG-2, 704 × 576, 4:3, 25 fps, 9.30 Mbps, upper field first

      Audio Tracks:
      128 AC3 2/0, 48 kHz, 256 kbps

      Stream Files:
      VTS_01_1.VOB (532.67 MB)

      My box is:

    13. admin says:

      Let’s see. Thanks for sharing detained information. That makes us analyze your situation closely. I hope other people who drop comments here will follow you in the way you report your situation.

      You say ‘upper field first.’ That may be the source of the problem as all DV video is encoded with the bottom field first. I’ll read what you said more closely and tell you if I find anything else.

    14. admin says:

      Sorry. That doesn’t explain the audio sync. According to Wikipedia, it says “DVCAM and DVCPRO both use locked audio while standard DV does not. This means that at any one point on a DV tape the audio may be +/- ⅓ frame out of sync with the video. However, this is the maximum drift of the audio/video sync; it is not compounded throughout the recording. In DVCAM and DVCPRO recordings the audio sync is permanently linked to the video sync.”

      But you already said that you’ve tried it with DVCPRO. So let me think again.

    15. admin says:

      Hmm… The problem seems to rather reside in the video file. Did you also say you choose ‘Fix Timecode Breaks’ under ‘Edit’ on top of configuring Preferences, and that doesn’t help?

      Try the following if you could:

      Open the VOB file with MPEG Streamclip and choose ‘Fix Timecode Breaks’ under ‘Edit.’ Use MPEG Streamclip to demux the VOB into M2V and AC3. Then read M2V with MPEG Streamclip and choose ‘Convert to MPEG..’ In the way, MPEG Streamclip should find M2V in line with AC3. Finally, convert MPEG into DV if you want to. If this approach doesn’t work and you still have the same audio sync problem with DV, you may want to abandon DV and use any of MPEG-4-compliant compressors instead.

      I downloaded an encrypted DVD using Mac the Ripper. (The DVD is royalty free use, but I want full quality so I’m using it from the DVD). Anyway, Mac the Ripper put it in VOB files. Now, do I need to buy Apple’s Mpeg2 software to allow your software-Mpeg2 Streamclip to allow it to convert it to a QT file? My goal is to import the DVD clip into FCP. I’m not sure of the relation between apple’s mpeg 2 software and your software, but I think I need both. Please tell me what I need to buy or use in order to get the VOB files into fcp. Thank you SO much!

    17. admin says:

      (1) We didn’t develop MPEG 2 Streamclip. We have never claimed that we did.

      (2) Yes. You need MPEG-2 Playback component to process VOBs with MPEG Streamclip.

      (3) MPEG Streamclip is a mediator that accesses QuickTime components. Therefore, just like you need MPEG-2 Playback component to process VOBs with QuickTime Pro, you need it with MPEG Streamclip.

      (4) A cheap way of handling VOBs is use of ffmpegX by major. It doesn’t require you to purchase MPEG-2 Playback component. You can use it convert VOBs into DV streams. Another way of doing it is use of D-Vision. D-Vision converts VOBs into MPEG-4-based video.

    18. 2gigs says:

      I would like to know what the best conversion is from a vob file, so I can edit it in Final Cut Express HD. And also if anyone knows, why am I not seeing all the frames in Final Cut. Am I doing somthing wrong? I probably am. Streamclip is awesome!!!!!


    19. admin says:

      > what the best conversion is from a vob file

      Your options are limited under Final Cut Express. Use DV.

      > why am I not seeing all the frames…

      I suggest you read ‘How to use this site’ (C) before posting your question in the first place.

    20. heenalu5 says:

      Completely amateur question here, I apologize. When I go export a file to Quicktime, I get a popup with all kinds of compression options. I want the best quality, so when I choose ‘Quality 100%’ and ‘Apple Motion JPEG A’, which is the default, it makes my original 19 mb MPEG file 164 mb. I don’t want to loose resolution in the conversion process, but 164 mb is way too large. Could you please recommend what settings I should be using?

      Also, is there a way to batch save?


    21. heenalu5 says:

      Ooo, found the batch save. Awesome! What a great ap. Still can’t figure out the compression though. I’m using a PowerBook with OS 10.3, and I plan to use Final Cut Express for editing. Thought I’d move on from iMovie. Thanks in advance.

    22. admin says:

      To begin with, try compressing video in H.264 or Sorenson 3.

    23. Moviefan says:

      Sorry if this has already been addressed, but after doing much research, I’m still a little unclear. I am looking to get the Panasonic VDR-D300 dvd camcorder but am a little hesitant because of all I hear about after dowloading the files to my Mac G4, how much quality I will lose because of the compression needed. This cam has VBR MPEG-2 and USB (no firewire). I doubt I’ll be doing very much editing, but if ever I want to, what would be my step by step process to get the footage from my mini dvd to a normal dvd using my Mac with the least quality lost? Or should I just forget about the dvd cam and go with a mini-dv?


    24. admin says:

      >what would be my step by step process to get the footage from my mini dvd to a normal dvd

      I don’t understand your question. You must use a video application like QuickTime Pro, (Final Cut Pro, Final Cut Express for FireWire) iMovie, iPhoto… to import video to your Mac. And which one are you using? Or is that also part of your question. Anyway, no matter how you do it, you will lose quality to some extent by the time you have the final version. In your case, since the video camera supports MPEG-2, the best option will be of using Apple’s Comressor, I suppose. The second best option may be of using MPEG-Streamclip to compress video in DV. If this is your choise, you will need Apple’s MPEG-2 Playback plug-in.

      I do not know the exact step because

      (1) we don’t own camcorders
      (2) I don’t know which app you are using.

      Good luck

    25. Scott E says:

      I’ve been working with conversion programs for a while and thought Streamclip was great for a lot of stuff, BUT…

      I extracted a DVD vob file sequence in Streamclip to m2v and AC3 files for use in DVD Studio Pro. When I try to use the M2v file, DVDSP gives me an “incompatible format” warning and will not import. I have the Mpeg component installed in QT and I CAN use files exported to DV, but using m2v files, encoding is quicker.
      I can do individual vob to m2v files from the same project in Mpeg2Works, so what’s going on? Are all m2v files equal?

    26. admin says:

      As we don’t use DVD Studio Pro, I cannot offer you much help. In my understanding, however, since DVD Studio Pro is a Pro app, aren’t you supposed to use Compressor? I know that the current version of Final Cut Pro doesn’t accept MPEG-2 any more. So Final Cut Pro users resort to Compressor.

      I have successfully ripped .m2t files from my Motorola DCT6412 from Shaw Cable. I have used MPEG Streamclip to edit out the commercials.

      I have several files from a series that I would like to export to DVD. Which codec should I use to convert the .m2t files so that I can use iDVD or Toast to burn the DVD? Which one is the best?

      I have a multitude of codecs – basically any are available to me since I have MPEG 2 codec from Apple, and FC Pro 5 with all its codecs.

      I didn’t know what Motorola DCT6412 and Shaw Cable are. Now, I know what Motorola DCT6412 is. It’s a high definition & DVD video recorder. Anyway, we don’t have it. So we can’t give you definite answers as we don’t handle .m2t. If you make it downloadable somehow, we’ll give it a try as I am now curious. Possibly, we can create a video tutorial for this. We had a file upload function before. But a hacker destroyed it. And I’m not going to write a PHP script for this for now.

      Hi, great software. Thank you 🙂

      I’m basically using Mpeg StreamClip to edit (cut out unwanted parts of) .avi files (DivX encoded) then saving them back to .avi, same dimensions, same frame rate, etc.

      Firstly, if I use the “Save As” option as opposed to “Export”, is this done without recompression, and thus lossless?

      Secondly, when I use the Save As command to save back to an .avi file I hear an audio pop at the cut point in the SAVED file, but there is no pop at all as it plays in Mpeg StreamClip. However, if I either Save As a .mov file or Export to say, .mov format or .avi format, there is NO audio pop at all in the saved files, at the point I cut out. Thus the audio pop ONLY occurs when I Save As an .avi file.

      This occurs whether or not my in and out points are on keyframes.

      Is there a reason for this? Is there any way to solve this problem?

      Hardware: iMac 2.16 GHz Intel Core 2 Duo, OSX 10.4.8
      Software: MPEG StreamClip v.1.8

    36. admin says:

      Just for your information, as we often explain over and over again, we are not the developer of MPEG Streamclip, and we have never claimed that we are.

      >Firstly, if I use the “Save As” option as opposed to “Export”, is this done without recompression, and thus lossless? => Correct. By choosing “Save As,” you are just changing containers from one to another.

      >Is there a reason for this? Is there any way to solve this problem? => We have no clue. But that’s a good point to make.

      I can convert but i can´t open it with a WMP or a BS Player.
      The “.mov” file have 1.9 Gb aprox. The “.avi” converted (DVPAL compressor) have about 9 Gb


    42. tbluewater says:

      WMP for Mac or Windows? I do not know what BS Player is. To my knowledge, Windows Media Player is designed to play back video that is compressed in Windows’ own algorithm. Video must also be formatted in WMV. You can use VLC from VideoLAN to play back AVI files.

    43. 10exp18 says:

      Sorry, maybe i have explained bad
      I convert from a “.mov” file of 1.9Gb to a “.avi” (DV PAL codec)and the size are about 9Gb. The conversion are made in a G5 2Ghz dual procesor. 10.4.8 MacOs version
      The MPEG streamclip makes the conversion, but when i try to open this “.avi” in a PC with WMP (or other player like BS player or Virtual Dub)i can´t.
      If i do the same conversion but the “.mov” file are more small, i don´t have any problem, and i can play it.
      The problem can be the size?

    44. admin says:

      How does the simple package swap of a 1.9-GB MOV file become a 9-GB AVI file? What happens if you try to open it with the Mac version of VLC from VideoLAN? Basically, we are only Mac people. So we can’t be of much help if the operating system is something else.

      >I have an earlier version of quicktime mpeg-2

      You mean, QuickTime MPEG-2 Playback Component? I don’t know for Intel Macs, but that’s the latest version for Power PCs. The reason why you have no audio with your VOB files is probably its audio stream is compressed in AC3. So it’s not the matter of the version of the QuickTime component.

      >will I need to use streamclip to sync audio and video?

      Tell me exactly what you want to do with your VOB files.

    47. George says:

      First let me clarify the mpeg-2 component. I have version 6.4.1 which was created for Quicktime 6, it’s a few years old. I installed it on my system which is Quicktime 7 and it is working. I was just asking if there is any advantage to upgrade to the mpeg-2 component version 7 Apple is currently selling on their website (for Quicktime 7).

      I would like to convert the VOB files to quicktime movies for the web and also convert them to iPodcast.

      We don’t own Intel Mac machines. So I do not know what the latest version of MPEG-2 Playback for Intel Mac is. What we have is 6.4.1 for PPC. That’s the latest one for PPC. Our QuickTime Pro version is 7.1.3.

      >I would like to convert the VOB files to quicktime movies for the web and also convert them to iPodcast.

      You need MPEG-2 Playback. If your MPEG-2 had not worked properly, you could not have opened an MPEG-2 file with QT in the first place. Therefore, the version you have is adequate.

      No, the MPEG-2 playback component you purchased for QuickTime will continue to work with QuickTime 7.
