Separate audio and  video inputs for Quicktime Broadcast?

I want to produce some real time streaming via Quicktime Broadcast. My audio will be coming from a Mackie mixer with firewire interface, the video will be coming from my video switcher which has a firewire output. Will I be able to combine the audio and video firewire feeds in the computer (or software), or must I combine the audio and video into one firewire feed before it hits the computer?
Thanks!
Rob Cook

I just did my first feed Monday night. I used a video mixer and Mackie board myself. I feed the audio and video(component) into my DSR-20 VCR, which I also use for a tape backup recording. This then feeds the QT Broadcaster. I don't think you can feed anything but a firewire machine or iPhoto camera into Broadcaster. Might work with an USB camera/vcr???
I feed H.264 video, at 320x240 with mono 16 bit audio. Hint... don't do disolves, as they increase the frame rate. simple cuts-only seems to be the best. We also fed keynote slideshow into switcher... carefull there, as it produces saturated colors that will effect the signal... the switcher will think the super saturated video is sync and glitch the video. red is the worst, of course. Next week I am going to use a little proc amp to drop the chroma a bit.

  • How do I combine separate audio and video files into one Quicktime movie?

    I have DVDs that contain separate audio and video files in folders marked Audio_TS and Video_TS. I would like to know how to combine these files into a single Quicktime movie. Is there inexpensive or shareware software that imports and unites these files reliably? A simple solution is preferred, rather than getting into complex media editing applications.

    Doug - the VOB files (in the VIDEO_TS folder) are MPEG-2 files. MPEG-2 have the video and audio mixed into the one file - there are no audio files to combine.
    The rest are directions to a DVD player (e.g. the BUP and IFO's) . The AUDIO_TS folder is used for DVD Audio discs and on video DVDs is always empty.
    Many people use Handbrake or iSquint to convert VOB to iPod video though MPEG Streamclip is the best - open the first numbered VOB and it will prompt you to open all of them. ALWAYS fix timecodes when it asks. You can then edit/trim and export to MPEG-4.

  • Exporting audio and video together for Mpeg2 dvd

    Hi, I'm trying to export audio and video together for Mpeg2 dvd.. I changed  multiplexing to DVD but is still exporting seperately is there something im missing? thanksa

    To add, with Multiplexing set to NONE, check what the Audio format is set to. If "PCM", this is an uncompressed .wav file and will result in export of .m2v video and .wav audio (I think Mac uses .aif) and use "Import as Timeline" in Encore for both clips at once. Encore will automatically transcode the audio to Dolby AC-3, do NOT mess with settings in Encore, defaults are correct. If you have CS6, then in AME audio settings, there is an option for Dolby and you can use that to create the .ac3 audio and then Encore does NOT do any transcoding to audio or video. Note that older versions will also show "Dolby" but that is a free trial of a surround encoder, not the same. You just want the stereo option available in CS6, or use PCM option is fine
    Thanks

  • Recording separate audio and video to iMovie?

    I have been experimenting with recording video directly to iMovie with my DV camera instead of using a tape (saves time, as I'd have to import it anyway). I was wondering if there is any way I could record audio from a different source (I have a digidesign MBox) at the same time. This way, I'd have better audio quality and not have to worry about syncing it later. If this isn't possible in iMovie, is there a program that it is possible in (preferably not an expensive program)? Maybe Quicktime Pro can do this?
    Thanks.

    I like Bengt's suggestions. You could try experimenting by opening a second program and record the audio using both iMovie and the microphone input. Since you can mute the camcorder audio in iMovie after syncing, the last challenge is the sync. Seems like a clapboard would work.
    Otherwise, look into a video converter box or something where you can mix the audio and video externally, and have it come into iMovie over Firewire at the same time.
    Or, check over in the Final Cut forum to see about those capabilities.
    Portable hard disk recorders for pros could have separate video/audio inputs.
    Bengt's plugin mic is sounding pretty good about now.

  • When exporting separate audio and video streams, the audio drifts out of sync

    So this is my first slightly larger project in Final Cut Pro X.
    When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
    When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
    What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
    I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
    I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
    So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

    Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
    Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

  • Separate audio and video feeds?

    Can I record video into iMovie from one source, while using another source for audio? I'd like to use my Canon ZR80 as a video source, but it has no audio input jack, so I have to use a lav or some other mic for audio.

    Can I record video into iMovie from one source, while using another source for audio?
    Are you trying to input the audio and video simultaneously or is the audio something you can do as an overlay? If the latter, then you can use the mic input or import previously recorded audio files from the "media" menu after you finish the video capture.

  • Audio and video compression preferences for export to DVDSP

    Hi,
    I have a few questions here. The first is regarding the internal use of compressor by DVD Studio Pro. It is my understanding from (limited experience with) past projects that quicktime movie files are automatically compressed to an mpeg2 format when imported into DVDSP. To what extent do I have control over the level of compression, and are the default mpegs that were made optimal quality? Where can I check this?
    My second question is regarding compression of audio files. Whereas my video files were automatically compressed, I am not so sure about the audio. I was forced to compress the audio down to Dolby2 separately using the external compressor program, in order not to exceed the bitrate on my last project. Was this just a question of one or the other (video/audio) needing further compression than the default amount, or is there more to this issue?
    I live and work with video in Europe, where I have recently been told that optimal audio is mp3? 4? rather than Dolby 5.1? Is this correct, and how much more space does dolby 5.1 take than dolby2? How significant an issue is this when making dvd's for musicians?
    Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe?? or explain how I might go about finding this out for myself?
    Thanks a lot, and I look forward to reading your comments.

    Settings for DVDSP's internal encoder can be adjusted in DVDSP preferences. Press Command-, - that's the Apply and the comma keys - to bring those up, then select the Encoder tab. In your case, make sure you adjust the settings for SD DVD (and not HD-DVD). You will also be able to specify whether to encode in the background (basically, as soon as you import your file) or encode on build, at the bottom of that tab.

    I can't confess to have read any of your previous threads, but if you exceeded bit rate, that is a common reason to need to use Dolby compression for your audio. (unless you can afford to recompress your video files)
    That is, if you video files use a high bit rate (say over 6 Mbps average), then it's usually necessity to use Dolby compression to make sure that all your footage fits on a single disc. (this is a simplification, of course, but I think you get the idea)
    Or was there more to this question that I'm missing?

    Someone was mistaken when they told you that DVDs accept - let alone are optimized for - mp3 or mp4 files. That's flat out wrong.
    As for the difference between Dolby 5.1 vs 2.0, that depends on your encoding rates. Typically, most folks encoder Dolby 2.0 at 192 kbps, with some choosing to up the bit rate to 224 kbps. Beyond 224 kbps, you're not actually improving audio quality for a 2.0 mix, you're just bloating your file size. When it comes to 5.1 audio, it's typical to encode your audio at 384 or 448 kbps.
    When it comes to compressed audio vs uncompressed audio, it does matter when you're making DVDs for musicians. But that means that you'll probably need to lower the bit rate on your video files.
    Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe??
    If you want to keep you audio as AIFF files, set your encode to 2 Pass VBR Best, with an Average bit rate of 5.0 Mbps and a Max bit rate of 7.0 Mbps. If you need things to happen a bit faster, use One Pass (not One Pass VBR) and use 5.5 Mbps as your bit rate.
    If you want to have a firm grasp over how all these numbers work, there is a section at the back of DVDSP manual, that explains how to calculate bit rates (what we call bit budgeting in the business). Give that a quick once-over if you can.

  • No video input for external devices on iMac 24" display???

    I got a 24" iMac a few days ago and love this thing. (Was in PC **** for last 30 years...) But one thing I am disappointed in is that there appears to be no video input to display video or to video capture. Is the only way to display video from an outside source by using a USB video capture device? For example, if I have a cable box or game console I want to display on the monitor, how can I do that? Seems silly to need to use a capture device to simply display video. Please let me know if there is simple way to do this. Thanks!

    I don't see how using a camcorder would help especially although it would be technically possible to use it as a bridge between other devices I can't see how it would be worth your while.
    Obviously not speaking from experience since almost all if not all DV cameras have passthrough, and feed video into a mac via firewire from the analog audio and video input port on the DV camera. They have been used for ages as decks (and are many times cheaper than DV decks) and as converters vs. buying a Canopus box etc., which are basically the same thing.
    The EYE TV 250 does the same thing with a USB connection and its own software but for the myriad of DV cam owners the passthrough is a fine idea.

  • Relinking Audio and Video

    I unlinked my audio from my video and now when I select all of my separate audio and video segments in the timeline and go to the modify menu, the link option is greyed out. Apple + L also does not work. If I select an individual video and audio segment I can link those, however, they do not become linked with the rest of the segments of audio and video. How can I relink everything back together?
    Thanks.

    on the whole, FCP does a handy job of keeping everything in sync for you, however there are a couple things you can do for more peace of mind:
    Whilst FCP doesn't have any specific grouping command for linking multiple elements together, it does have something called "nesting". With nesting you are collapsing any selection of items into a single clip item ... actually you are taking those multiple elements and saving them as a separate sequence, then replacing those elements in the original sequence with a single clip item which references that new sequence. You can read up about nesting in your manual, or take a look at this tutorial over on lafcpug's site: http://www.lafcpug.org/tutorials/basic_nest.html
    And DUPLICATE YOUR SEQUENCE OR PROJECT BEFORE YOU START ANY MAJOR MESSING ABOUT (excuse the caps, i got carried away) ... but you should make a copy of things before you make major changes so that you can easily revert if necessary, autosave is great and all, but knowing you made a copy is never a bad thing.

  • Consolidating audio and video

    I created a movie using separate audio and video from three separate disk drives.  I would like to consolidate all media used on one of the drives.  Will the consolidate media do this or does it just consolidate video?  Can I leave my original media where it was originally or will it be move with the consolidation?

    You choose Comsolidate Media for a Project. When you do, it will Move (or copy) the events used in the Project to the same drive as the project. It will also copy any audio tracks from iTunes or photos referenced in the project to the same drive as the project. This is a good command to use when you want to edit a project on a different computer, because it puts everything you need in one place.

  • Synching audio and video not working

    I recorded a separate audio and video clip of an interview, and I marked the start of the clip with a clapperboard and spoke the take number and contents to make life easier, as I usually do. The gear is borrowed from the college, and for some reason the audio that came out of the Canon 5Dmkiii was really low. This could be the reason why, when I put both the video and audio into their own bin and right click and merge clips, (with the syncronisation point as audio, and under audio tab checking the box to remove audio from AV clip) that the clip doesn't seem to recognise the snap of the clapperboard or something maybe? Is there any way I can correct this, or do I need to synch it manually? If so, is there any quick and easy tutorial on youtube or something that is recommended?  

    I discovered that if I put markers manually on the point where the clapperboard snaps, and select marker instead of audio as the synchronisation point, then it synchs up the clips properly.

  • How to get audio and video in one file

    hi...I am "premiere beginner user" and I have a simple question , I think..:)...Every time when I am trying to export media out from my premiere (using media encoder) I get video file and some audio files, but what I need is only ONE file, that contains both (audio and video)..for example , I have edited film in hd quality and I want it to export, I choose h.264 format(make some settings,pal,audio quality...) and when it´s "all done", only "result" I get is one video file and two audio files and they are not together :).....so please help mme anyone..ok and as you can see I am not from english speaking country, so sorry for my english...thanks for help....

    There is no indication that something is out-of-sync or the ability to move/slip into sync like in FCE/FCP.
    To the best of my knowledge, using match frame and overwriting the video with video+audio (or attaching it as a connected clip if you don't want to overwrite the video, which might have effects applied) is the best way to do this.
    You can use the blade tool first in the timeline to get just the section you want to get back into sync. Make cuts so that you have a single clip that needs the audio resynced, select it, and use shift-F to select the original synced clip in the Event Browser. Make sure your play head is at the beginning of this video clip in the timeline. Press option-2, then 'q', and now you have the audio back in your timeline, synced with the video.  Delete the old, no-longer-synced audio and you should be set.

  • Audio and Video on the same page.

    Is it ok to have a separate audio and video file on the same page?  Both are set to auto play with no controls but when I try this set up the audio seams to override the video, stopping the video a few seconds later.
    I guess I could try and embed the audio into the video but if I did not have to I was not going to.
    Any suggestions or help is appreciated.
    Thanks,
    Ryan.

    You can't play both the audio and the video simultaneously, you'll need to merge them.
