Shrinking audio/Quicktime files in iWeb

I used the podcast template for my website. All my audio files were created in ProTools. The .wav files are often 40MB to 60MB. I have no problem playing the pieces on a Safari or Firefox browser on my iMac or MacBook -- but someone on a PC with perhaps a slower bandwidth told me she could only play ten seconds of every piece. I suspect the files are too large. Does anyone know a good way on a Mac to shrink a file size down? Or is the problem that Quicktime doesn't work on a lot of PC browsers?

The .wav format doesn't use any compression so the total file size could be very large.
Use something (even iTunes can convert) to shrink them down in size.
Mono would cut the file size in half. Mono plus halving the frequency (44100 becomes 22050 Hz) would cut it to one quarter size.
AAC or MP3 compression can also adjust the bit rate. Spoken word doesn't need a 128 kbits/sec rate. Your WAV source is probably 1411 kbits/sec. Cut it down to 64 and now it is 20 times smaller in file size.
No "Podcast" should be over 1MB per minute of file.

How to shrink a quicktime file of 93.3 gig with handbrake

Thanks for the info. I did try to use Handbrake, but when u navigate to the source file, it says no valid title found, I wondered if this was because there was no suffix, tried MP2, and 4 and MOV, no joy, offhand couldn't think of what other suffixes to try. version of handBrake in use is 0.9.1 any suggestions as to how I could get HandBrake to recognise the source file would be appreciated

Handbrake will quite happily provide conversion facilities: http://handbrake.fr/
I'd choose MP4 / H264 as the codecs / container, keeping the same resolution. a 2 hour movie for those dimensions at a bit rate of around 2000 shouldn't come in above 1GB (a huge reduction for you)

Quicktime file with corrected audio track not working with iWeb Gallery

Hello Everyone,
I shot a video and accidentally recorded on one audio track only (posted in another post). I've fixed the audio in Quicktime Pro by selecting the audio track (track 1) onto track 2 and hence I've got "fake" stereo or mono audio. The QuickTime file plays perfectly on my desktop. The audio is coming through both channels, as well.
Now, my problem is that when I've tried to upload the file to my iLife '08 iWeb site, the audio is back to one channel again. The video plays beautifully, however. I even uploaded the QuickTime file to my iDisk and from there to my web gallery through iLife '06. Still, the audio is only coming through on one track.
Hmm, is there a setting in QuickTime Pro that I might have missed after I "fixed" the audio? Like I said, the file plays perfectly on my desktop. I've even burned the file to DVD and it plays perfectly on my home DVD player. Somehow along the upload process the 2nd audio track is dropped. Any advice is very much appreciated.
Frustrated in Texas,
-Jack

Hello QuickTimeKirk,
Thanks for all of your advice and to the others who have chimed in with their input. My audio problem is solved. The problem with one of the audio tracks getting dropped once the QuickTime file was uploaded to my Web Gallery has been fixed. I had to re-export the original QuickTime File and somehow the tracks corrected themselves. I believe they were canceling themselves out the first time. Weird.
Now, however, I see that I'm getting the blue Quicktime symbol when I open the URL. It takes about a minute (at least with my cable connection) for the poster frame to show up. I did flatten the file and have it set to play automatically. See what you get on your end: http://web.mac.com/honeybear7/Site/Movie.html if you don't mind. This is just a test page, so this is not the final presentation. The window size of the movie, however, is set.
What is the best possible setting I can have the file set on for it to play the quickest? I know much of it is dependent on the connection speed. This also is not a small file. It's 214 Mb, but it's a 40 minute movie and looks okay on the web. Having burned it on DVD as a 2.9 gig file it, of course, looks much better with no blocking. I originally shot it with an HD Canon camera.
Any more advice is greatly appreciated. Have a great weekend.

Export QuickTime file with new audio and maintain the file size and quality as the original.

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for the client and deliver them as the same QuickTime file but with the clean audio and keep the file size close to the original and not have quality loss in the image?
If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size. They did request that they be Quicktime MOV files though so that is a must.
I don't see this as an option in the codecs in the export settings in PP, but is there a way to export as ProRes or another MAC native codec that will save them from having to convert it on their end? I am on a PC with Adobe CS5.5 so I am not too familiar with MACs, but from what I understand they would need to convert the files if I sent them straight out of the camera.
I found some related search results for this but they pertained to "Best quality" for export. I am not sure how the varying options work but I don't want to create files that are considerably larger, just not less quality.
If anyone has experience with this it would be greatly appreciated.
Thanks,
Cole

Here's the workflow: I imported the video footage into iMovie '08 and did my edits. Then I exported it (share) to my desktop with compression set @ 740 X 480. Then I used QuickTime Pro to fix the audio track. The file plays perfectly with both audio tracks working. It's a QuickTime file (.mov).
I hope this jars any replies as to why the file when uploaded to my iWeb gallery drops the second audio track.
Hmm,
Jack

How do I export from FCP to a QuickTime file with multiple audio channels?

I'm delivering a project where the first step is to generate an HD Cam SR master, which I will be doing at a post-production lab. They will then do a QC check for me. To generate this HD Cam SR master, they need to me to bring in my 98-minute long movie on a firewire hard drive, in five equal parts -- QuickTime files. From these five QT files, the lab will then be creating an HD Cam SR master that will have...
dialogue on tracks 1 and 2
effects on tracks 3 and 4
music on tracks 5 and 6
MY QUESTION
a) I don't see any way to separate these audio tracks accordingly in the FCP menu for QuickTime export. Does anyone have any experience doing this?
b) And does anyone know the most efficient way to combine timeline audio tracks for this purpose? I have my dialogue sitting on the first FOUR audio tracks, actually. To deliver this film, I'll need to crush these four audio tracks to two, as listed above. I could generate an AIFF file, I suppose, import it back onto the timeline, sync it up, and then re-export along with the visuals to make the final QT file, but this seems like a generation loss.
thanks,
Shanked
PS the movie is made up of footage from a Sony PMW EX1. I used the codec "XDCAM 1080 24p 35mbs VBR" for editing in FCP. I'll either export to QT using this same codec or switch to "Apple ProRes" if my machine can somehow maintain the sync.

The following will answer both your questions a) and b).
Click on your master timeline and press cmd+0 (zero) to bring up Sequence Settings, then click on the Audio Outputs tab on the right. Click on the Outputs option and change it to 6. You can leave them as Stereo pairs.
Now, back on your timeline, you need to make sure all your audio is organised so each track. A1, A2, A3, A4 etc has all the relevant media on it.
Then, on the left of the timeline you see the Destination toggle buttons, then you see the Padlocks to lock tracks, then you have the Toggle Auto Select squares. If you right-click on the Toggle Auto Select squares you bring up a little sub-menu, at the top of this list you'll see Audio Outputs, which will show the stereo channels for that particular track. As you've changed the number of Audio Outputs in the Sequence Settings, the list will show: 1&2, 3&4, 5&6. You just tick whichever channels you want.
In your case, you have dialogue on the first 4 tracks, no problem, just go down through tracks 1,2,3 and 4 as described above and assign these to Audio Outputs 1&2.
Then just go down through your music and effects audio tracks and assign them accordingly.
Now, when you export your timeline as a self-contained media file, it will have different audio channels.
I hope that makes sense. When you change the number of audio outputs as described in the first step, I believe the rest of it is fairly self explanatory, once you know where the settings are.

Audio and video not in sync when exporting to Quicktime file

I use a digital camera to shoot video, which is in .avi format. I then import the clips into IMovie HD (selecting all the clips and dragging all at the same time into IMovie). If I play the video from beginning to end in IMovie, the audio and video line up fine. But, when I 'share' to Quicktime file, the longer the video is, the more out-of-sync the audio and video become.
I didn't have this problem when I used a mini-DV cam and imported using a firewire cable (in real time).
Any ideas as to how to get the audio to sync up with the video once it's shared as a Quicktime file? I've tried .mp4 and .mov, and I have the same problem.

Anything here help?

Play a QuickTime file with eight separate audio channels

I'm trying to play a QuickTime file with eight separate audio channels but they only play in stereo...... the same QT file will play all 8 channels separately in Qlab, which has separate level controls for each channel, and which "sees" my Digidesign 002 audio interface. But QT does not recognize the interface, nor does Audio MIDI Setup utility, apparently..... it will play all 8 channels mixed to stereo through channels 1 and 2

The following will answer both your questions a) and b).
Click on your master timeline and press cmd+0 (zero) to bring up Sequence Settings, then click on the Audio Outputs tab on the right. Click on the Outputs option and change it to 6. You can leave them as Stereo pairs.

NEED HELP PLEASE!!!! No audio when importing a quicktime file

I am trying to edit a project and I have it on an external hard drive as a quicktime file. When I play the quicktime file it has good audio. When I import the file into FCP I lose the audio...
Have you ever had this problem... PLEASE HELP!!!!

Thanks... I have downloaded streamclip... now how do I demux the clip and demux to what.... Sorry if these are stupid questions!!!! It is not allowing me to choose demux only export to MPEG... will that work? if not is there a trick to get it to allow me to choose demux?
I appreciate the feedback and help Very Much!!!!!!!

Audio sync problem after saving to QuickTime file

Hi there, I'm relatively new to Adobe Premiere - I'm not quite knowledgeable enough about video editing to really use it to its full potential but needed something more flexible than Windows Movie Maker. I haven't had any problems before editing smaller files, but am having tons of trouble with a 2.7 gig file.
I'm trying to take a 2.7GB .MOV file recorded on a Kodak Zi6 and divide it into three roughly equal parts to use an email sharing service that has a maximum file size of 1GB (I know that there are sites that will allow 3GB files and I wish I could use them, or use an FTP server, but the person who needs the video needs it to be sent over his own company's file sharing system). It was recorded on an 8GB SD card, that SD card was put into my computer, and I then transfered it over to Premiere Elements 8.
I rendered the entire file first (it wouldn't even play until I did that) and after rendering, the audio and video were good and everything was synced up. I then split the clip into three and saved each as a separate project. Then I opened one up again and tried to save as a Quicktime file (that's what the person I'm sending it to requested). All seemed to go well, and for the first minute or so of the 15 minute clip everything is great. Then after that, the audio gets more and more out of sync as the video plays on. I tried playing it on several different players, same thing.
My computer (a Cyberpower PC) is running an Intel Core i7 CPU, 870 @ 2.93GHz 3.06 GHz; 8 GB of RAM; NVIDIA GeForce GTX 285; Windows 7 Home Premium. I'm not sure where to get the rest of the information requested in the "How to best ask for help" post but if you can give me some guidance I'll find it.
The presets are on the defaults because I wasn't aware of them until I came to this forum. Happy to try the whole process again if someone can tell me what the presets should be changed to.
I'm looking for a solution to this particular problem, but am also looking for some basic help about files. The files that I used most often usually come from a Kodak Zi6 (.MOV) or a Flip Mino HD (MPEG4 I think; had to convert those to something else to use them in Premiere at all). I have AVS Video Converter 6, so I can convert those files to pretty much anything. I'm wondering what I should convert files to before trying to edit them in Premiere, and how best to save them. I rarely use the files anywhere but online if that helps (this particular 2.7GB file being a big exception) at a maximum width of 550 pixels, so I don't think I need the quality to be all that great; it's more important to me to be able to work a bit quicker, without rendering that takes hours.
I'd also love to take advantage someday of some of the more advanced features of Premiere, so I was wondering if anyone knows of any tutorials that will walk me through things in a linear way (as in, start from the beginning and teach me what I need to learn before moving on to something more complicated).
Thanks so much for your help, and please speak slowly; I'm in over my head!

Very well-done post, and welcome to the forum.
First, many have issues with OOS (Out Of Sync) with QT files on Export/Share. This is not just with PrE, but PrPro also. Unfortunately, OOS is pretty easy to fix, when you encounter it on the Timeline, but almost impossible to fix when it creeps in during Export. As an aside, I fought some MPEG Audio from a client, that was perfect in the Timeline, but when Exported to MPEG-2 for DVD-Video, ALWAYS went OOS dynamically, and even adjusting for that on the Timeline (rather guessing how much OOS the other direction I needed,) just flat would not do it. Sync would be fine for awhile, and then suddenly start going out, before miraculously returning to sync with the next Clip. Never could get that one correct.
In your MOV Export/Share, I am not certain which CODEC you chose. Was it H.264?
Within the MOV "wrapper," did your recipient give you any options for the enclosed CODEC's, or is the wrapper and the file size the determining factors?
Wish that I had more to offer directly, rather than questions.
As for the tutorials, I strongly recommend Steve Grisetti's Learning Series, his Boot Camp and his many articles and general PrE tutorials on Muvipix. He also has several books, available there too.
Good luck,
Hunt

Quicktime file audio won't render in FCP

Hi and please help if you can
I have converted the windows media video files (with the extension .asf) into a Quicktime file using Quick Time Pro and Flip4Mac. I am trying to use the converted video in FCP, but when I import the converted quicktime file into FCP and I render the clip, the video will render and play fine, but the audio will not. I am getting the unrendered audio beeping sound. Did anyone encounter that problem before? Any advice.
Thank you in advance.

Try a one minute "cut" from your .asf file and export to DV Stream.
Too many Windows formats do not follow anything except M$ formats and can't be converted from a Mac. Maybe try the export from a Windows box?

Problems with audio in quicktime file for dvd authoring

i have converted sequence into quicktime file for burning into dvd. i have am experiencing some problems with voice over which disappers and comes back later in the quicktime file when i play it. this quicktime file is made as self contained movie. I have traced this back to the original sequence in the timeline to a white line or series of line in at the top of the time line. one is for video and the other is for audio. when the first line appears the voice over gets interrupted and audio stops in the quicktime file but its ok in the timeline. when the white line shows again the voice over can be heard again in the quicktime file and audio stops again at the start of another white line. there is no loss of audio in the sequence in the timeline. so please can someone help me understand what the problem is.

thanks tom. i am refering to render bar in the timeline, upper for video and lower for audio. May be i shoud describe them as white line gaps between dark grey or steel grey bar color.
what do you mean by down mixing? please advise

Exported quicktime files have video & audio out of sync

I am using FCP with a Sony HVR-Z1E. All seems ok in my edit etc but if I try to export my edit to a quicktime file using the quicktime conversion option the audio and video are out of sync on quicktime. If I export using quick time movie option, all is fine as this file is played back by FCP. I have tried different settings but I cant get the audio to be in sync with the video. My settings are HDV 1080i50 on my 15" Macbook Pro
Thanks for any help
Regards Alf

You can open your "quicktime movie" (not qt conversion) in quicktime player. Simply control click on the file in the finder and choose open with... Try that and let us know if the file is in synch.

Autoplay audio files in IWeb (pre-'08)

Hello, I am a new user of IWeb and, while I find it very easy to use, I am baffled about how to add music to a page. My aim is to add the song (taken from Itunes so presumably correctly formated) in such a way that it will play automatically when the page is loaded. I am correct in assuming that this function (autoplay) is not available in IWeb earlier than the '08 version?
Any feedback will be much appreciated.
Thank you,

See this article: _Add music and Popup windows to an iWeb created website_. Note what chapter 7 there says about iTunes music.

I don't think that "autoplay" per se is the problem — it's more to do with the fact that iWeb '06 doesn't give you the tools to +easily set up+ autoplay — such as iWeb 08's +HTML Snippet+ window and the QuickTime tab in iWeb 08's Inspector. Adding HTML in iWeb '06 is explained in this article: _iWeb FAQ - (alternative) Adding HTML_.
It's not quite what you want, but take a look at Apple's "My iTunes widget". But again, this would be much easier to incorporate into your site using iWeb 08's +HTML Snippet+ window.

Is this a Yosemite issue? Not being able to play older QuickTime 7 files properly? I'm not sure what else the issue could be since everything seems to work fine in 10.7, 10.8, and 10.9 (unfortunately, I have been unable to test this in 10.10 or 10.10.1). Maybe I'm overcomplicating a simple issue? Any help would be greatly appreciated.
Thanks!

Some very interesting observations which peaked my own curiosity due to on-again, off-again nature of the playback. I suspect this is either a "bug" or represents content handling changes that are currently in the process of "evolving." Not a web site programmer so I used iWeb to run some contrast-comparison tests on how audio was handled by the plug-in software when directly accessing the content by its URL and via the page embed strategies. My results mirrored yours in that:
1) All legacy codecs tested (A-Law, IMA, QDM2, QPV, and u-Law) in an MOV file container played correctly in the QT 7 player.
2) The same files all played correctly when content was accessed by the plug-in software directly using the URL reference.
3) None of the files containing legacy audio compression formats would play audio using the plug-in software using a web page embedding strategy.
4) An MP4 (H.264/AAC) version of you original clip played correctly in all instances.
5) Replacing your QDM2 audio track with an AAC audio track in the original MOV file allowed the file to play correctly in all instances.
Based on these observations, I suspect the problem is in the way the software is currently programmed to handle (or rather ignore) the embedded strategy content. However, as you indicated, it is probably time to update your files. Not only did the H.264/AAC version of your original file play in all instances, but it used less than 45% of the file space/bandwidth for the settings I employed as compared to your original "0706_split_brain_red.mov" original file.

Save logic .aiff as quicktime file

Hey,
I posted this question in the iweb board and got some interesting ideas but was curious if anyone here had any other thoughts.
I'm adding short .aiff's to an iweb site for people to right click and save.
-I'm making the .aiff using logic express.
-Bouncing to desktop.
-under "get info" I'm changing the .aiff to "open using quicktime player" which makes the file look like a quicktime file with the big "Q" on it. When I double click on the file, it opens with quicktime player. All's good!
-I create a text box in iweb and link the .aiff (actually they are .aifc) file to text box, just regular stuff for creating links for files.
-After I publish site to folder. When I go in and right click on the link to save to desktop, the file I thought used quicktime player becomes an itunes associated .aiff file with the itunes colors (green) and opens using itunes, thus adding the file to my itunes library.
I'd like people to be able to click on the .aiff and quicktime player would automatically open and play the file, this way unwanted stuff won't be added to people's itunes library. Maybe I'm making a mountain out of a mole hill, but it would be nice to stay out of peoples itunes libraries, it's kind of annoying when stuff is added to mine that I don't want. Know what I mean (in a cheesy Elvis voice)?
Any thoughts on how to keep the file a quicktime associated file after download?
Thanks, byt
ps, I've been looking up the difference between .aiff and .aifc. It looks as though they are about the same except you can compress .aifc. Does it really matter which is which if you're not compressing or anything and just clicking and playing?

iWeb only uses QuickTime formats (or those it can play) in your html files. It (version 1.1) uses special javascript files to hold the source code and for non "standard" QT formats it use the special qtsrc tag to "force" the browser plug-in to play the file.
Setting the Get Info properties on your computer doesn't change the file format for other users or viewers of your file.
Since the QuickTime browser plug-in will be opening the file only QT Pro users will be able to "save" it.
If you are "linking to a file" instead of using the browser plug-in the viewer will either get a download or the file will open in a new browser window. If the QT browser preferences are set to open .aiff (or aifc) your file will open in new window. You make these settings via the QuickTime sys prefs/Advanced and clicking on the MIME Settings button. You'll see .aiff under Audio.
If you want to "force" a download you should use the Finder to create an Archive. Your file will now become something.aifc.zip and users will download it when the click the link.
It will still open in iTunes for those users that have .aiff set to open in that app.
Better would be to convert it to .mov format which is always associated with the QuickTime Player. You would still want to archive it before adding it to iWeb so that it downloads instead of playing in the browser window.
