QuickTime Pro 7 No Audio on Export

Hello!
I've browsed the forum to see if my question has been asked before but didn't find anything.
This is what's happening. Out of 10 or so short clips (about 1 min) I made one 10 minute clip for youtube, by copying and pasting all of the clips toghether. So far so good, I have my 10 minute movie with audio and video. The problem comes when I try to export it from movie to quicktime movie format...only the first couple of mintues have sound, afterwards it's a silent movie, no audio can be heard.
When I've pasted only 3 or 4 clips together everything's been fine. This is the first time I paste so many vids together.
All the clips were recorded on the same camera and are of the same format.
Hope you can help me out.
Cheers,
Santiago.

My camera gives me movies in MPEG1 Muxed format. I have good video AND audio. But, when i try to downsize these movies by export or share (within QT Pro), there is no audio settings allowed. So i get smaller sized movies with NO AUDIO!MPEG-1 employs interspersed blocks of audio and video data in a single data stream for spatial synchronization. QT is temporally synchronzed "frame-to-frame" audio and video. These are two different technologies. Basically, this means that QT only supports MPEG-1 movies for playback -- not editing and conversion. Use a third-party MPEG based converter like MPEG Streamclip (free) to convert these file and retain audio.

Use QuickTime Pro to extract audio from VCD

Can I use QuickTime Pro to extract the audio from a VCD? after that, I would like to convert that audio file to an mp3.

MPEG Streamclip is exactly what I needed. Thank you!
For others with the same need, here's my workflow for Extracting Audio from a VCD:
* Pop the vcd into a computer and open it up.
* Navigate to the MPEGAV folder. You should see something like AVSEQ01.DAT.
* rename that to AVSEQ01.mpg
* Drag this new .mpg file into MPEG Streamclip
* File/Export Audio . . .
* Open up Audacity (optional)
* File/Open . . .
* direct it to the newly created .mp3
* Trim off any extra audio (I didn't want the opening credits, etc. on the .mp3)
* File/Export as .mp3

Quicktime Pro 7.6.2 = SAVING EXPORT SETTINGS in the Settings List...

Hello,
I do most of my compressions right out of Quicktime Pro 7.6.2. It's fast / it's easy / it does a great job. On every one of my final compression jobs, there are 3 files I must compress:
* H.264 / 1280 x 720 / 29.97 / 8 mbps / Linear PCM audio
* H.264 / 640 x 360 / 29.97 / 3 mbps / AAC audio
* WMV / 1280 x 720 / 29.97 / 8 mbps / Uncompressed Audio
Currently, I have to change each set up (all settings) and export each individual file. There is no way to "SAVE SETTINGS" in Quicktime Pro...or is there? How can I save the settings??

I wish man. No plans right now, I have my 3rd baby coming in 13 days. Not to mention I have to spend $2000 on fixing my crawlspace.
I will be able to purchase my 50" Plasma soon.
AAAAAGGGGHHH!!! I SAID I DIDN'T WANNA GROW UP!!!! BUT IT HAPPENED ANYWAY!!!! (not yelling at you, just yelling at time, stupid time)
I do have a Intel Dual Core 2.16Ghz w/ 2GB RAM, 500GB HDD, will that get me by ewith FCP?
Thanx,

Quicktime Pro Record Webinar Audio

I'd like to record a webinar (audio) that I'm listening to Tomorrow night.. I've been searching the net for a program that can do this ? Can I do it with Quicktime Pro ?
Any helps or explanations would be most appreciated !!

QuickTime recordings can only be made from input devices and not from what plays through your speakers.
You need an audio capture software app like WireTap.

Quicktime Pro won't play FCPro exported Qtime mov

I exported mov files from Final Cut. But Quicktime won't play them.
Have installed some 3rd party Codecs but no joy.
What do you think is the problem?

I exported mov files from Final Cut. But Quicktime won't play them.
What audio and video compression formats did you use? Are you trying to play them back on the same computer or a different one?

QuickTime Pro - Annotations for audio

I have started using QT Pro recently, was successful in recording a speech, added annotations, and saved it as a .mov file. Later I exported that file as a .m4a (mpeg-4 audio file)and it lost all the annotations. Have tried exporting it as mp4 (mpeg-4 Movie) and it won't keep the annotations. What am I doing wrong? Is it not supported in audio files? If not, any suggestions on how to add annotations to an audio file?
TIA.

I got them from my friend who just sent them over to me through the internet. He imported them from his Panasonic HVX200 HD Camera into Final Cut Pro, then sent me the raw files.
The "Format" under Movie Inspector is as follows:
DVCPRO HD 720p60, 960 x 720 (1248 x 702), Millions
16-bit Integer (Big Endian), Center, 48.000 kHz
16-bit Integer (Big Endian), Center, 48.000 kHz
16-bit Integer (Big Endian), Center, 48.000 kHz
16-bit Integer (Big Endian), Center, 48.000 kHz
Please let me know if that helped any.
Thank you!

Quicktime Pro Applescript - Assign audio channels

Hi, I have been trying to find an applescript which would open a Quicktime Prores file which has multiple audio tracks in, either 8 mono tracks or 6 mono and one strereo track, currently all audio tracks by default have the 'Channels' assigned to mono. I currently have to go in and manually assign every track, using the dropdown menu to Left, Right, Center, LFE, Left Surround, Right Surround, Left Total, Right Total, but was wondering if this could be done with an Applescript as I have lots of these files to do regually. Another post I saw was able to change the 'name' of the tracks but not the 'Channels'.
I am on Mavericks with Quicktime 7 Pro.
Kind regards.

Hello
If I understand it correctly, the script listed below will do the job.
Please edit the channel_layouts_map1 and channel_layouts_map2 as you see fit. The former is for 8 mono tracks and the latter is 6 mono tracks and 1 stereo track. Each entry in the map consists of a list of three items such that -
item 1 = (string or int) name of index of target sound track
item 2 = (string or int) new name for target track (int i denotes original name of sound track i)
item 3 = (list) list of audio channel layout(s) in the target sound track
Currently, script will remap the audio channel layouts and rename the sound track as specified. If you don't want to rename the tracks, specify the same value for item 1 and item 2.
If the script is run in AppleScript Editor, it will ask you to choose movie file(s). If it is saved as applet (droplet), you may drag-and-drop movie file(s) onto it. It uses GUI scripting to reassign audio channel layouts, so you need to enable GUI scripting, that is a bit complicated under 10.9.

OS X: Using AppleScript with Accessibility and Security features in Mavericks
http://support.apple.com/kb/HT5914
Briefly tested with QuickTime Player Pro 7.6.6 (1710) (QuickTime version 7.6.6 (1800)) under OS X 10.6.8.
* Script will override the original files. Please make sure you have backups of original files.
Hope this may help,

QuickTime Pro For Mac Hangs When Exporting, Small BlankWindow Appears!

I am trying to export a movie file with the following settings:
VIDEO:
Compression: H.264
Quality: High
Key Frame rate: 24
Bitrate: 4000 kbits/sec
Frame recording: yes
Encoding mode: multi-pass
Dimensions: 480x360
SOUND:
Format: AAC
Sample Rate: 44.100 kHz
Channels: Mono
Bit rate: 128 kbps
When I try to export a file, regardless of setting, it hangs up and I must force quit. I get the "Spinning Beach Ball" and nothing is export also no progress window just a blank small window,I'm using QT version 7.4.5 on "Tiger"ver.10.4.11.
After staying up all night trying to figure out the problem, I gave up and just used an older version of QuickTime ver. 7.2 which worked just fine.
Thanks for any help with this issue.

Audio upsampling in Quicktime Pro: Best export settings for Final Cut?

I'm using Quicktime Pro to convert audio from 32 kHz to 48 kHz, for use in FCE/FCP. Quicktime gives me several options for export settings. I want to make the conversion lossless, without increasing the size of the audio file too much.
These are the settings I'm using so far:
Format: Linear PCM
Channels: Stereo (L R)
Rate: 48 kHz
Sample Rate Converter Settings: Quality: Best
Linear PCM Settings: Sample size: 16 bits
Are these settings the best choices? Does anyone have experience doing this kind of upsampling?
Here are the other options in Quicktime:
Format: Linear PCM, A-Law 2:1, IMA 4:1, MACE 3:1, MACE 6:1, QDesign Music 2, Qualcomm PureVoice, and mu-Law 2:1
Channels: 2 Discrete Channels, Mono, Stereo (L R)
Rate: there are other choices, but I know 48 kHz is what I want
Advanced Settings:
Sample Rate Converter Settings: Faster, Fast, Normal, Better, Best
Linear PCM Settings (when Linear PCM is the format): 8 bit, 16 bit, 24 bit, 32 bit (floating point checked), 32 bit (floating point unchecked).
The file size grows quickly as you increase the Linear PCM bit settings.

You can't create something that is not in the file.
Moving from 32kHz to 48 will only make the file size
larger and can't improve the audio.
Doesn't FCP or FCE import your file at 32. Or does it
change it to 48 after import?
I am aware that increasing the audio from 32 kHz to 48 kHz will not improve the quality of the audio. And yes, Final Cut Pro and Express will both capture and allow you to work witih 32 kHz audio.
I have several hours of video shot with 32 kHz audio settings that I'd prefer to have stored on disk with 48 kHz audio, because (a) some applications like iMovie have demonstrated problems with 32 kHz audio in the past, and (b) the majority of my video is shot with 48 kHz audio, so my 32 kHz video will eventually end up in a 48 kHz project, leaving the upsampling to Final Cut. Yes, I do eventually plan to burn my projects to DVD as well, but this isn't an immediate concern.
The problem with doing the conversion in Final Cut is this: Some of the people knowledgeable about Final Cut Pro and Express recommend doing the upsampling using Quicktime or another application, instead of using Final Cut, because Final Cut may not do as good a job as Quicktime. So my intention is to upsample the audio now in preparation for later projects. I don't completely understand why Final Cut wouldn't do as good of a job at upsampling, but a couple of experienced users in the FCP and FCE forums have independently corroborrated this.
Thanks to everyone for their helpful posts and responsiveness.

No audio when exporting to 3gp ~ Quicktime Pro.

Hey guys!
I have looked everywhere for the answer to my problem, but cannot find an answer anywhere!
I have Quicktime Pro and am trying to export video files to 3GP formats to view on a mobile phone. The problem I have is that about 95% of the video files I have will let me convert the video, but not the sound ~ it says "No audio in source movie." I can't understand this as there is definately audio there (I can hear it!), but I cannot change any settings to switch it on! I have tried AVI, MPEG, & other file types, but to no avail... Can someone help!?!
regards,
Richard.

The most likely cause is that you are attempting to export from muxed mpeg files (mpeg-1 or mpeg-2). QT does not support the export of sound from such files:QT Mpeg Limitations
You can determine if this is your problem by opening the video in QT Player and opening the MovieInfo window, where the file type and compressor are identified.
One workaround if they are mpeg-1 is to download this freeware Windows application. It will allow you to convert mpeg-1 to uncompressed avi files (just open the mpeg and use Save as Avi from the File menu). QT will be able to read these files and will then allow you to convert to your choice of formats, like 3gp, with the sound intact:VirtualDub

Export H264 pass-through movie with embedded text track QuickTime Pro 7 Windows?

Using QuickTime Pro 7 for Windows, I add a text track with closed captions to my H264 .mp4 videos.
The text track works great until I try to export it. After I've added the text track, the text track is displayed as long as the track is selected to be active using the Movie Inspector track GUI.
My movies are encoded as H264 for cross-platform compatibility, and need to remain in this format. The only way to save them in QuickTimePro 7 for Windows is to Export Movie to MPEG-4. I select Pass-Through mode to retain the resolution and bandwidth parameters that I initially encoded the video with.
Unfortunately, after I export to MPEG-4, the caption track is lost. It disappears. When I open the newly exported MPEG-4 caption file, and select Movie Inspector, the caption track is missing. Inspector only shows video and audio tracks.
If QuickTime Pro 7 for Windows correctly exported my text track with the video and audio tracks, then users would be able to view the closed captions upon playback in QuickTime Player by selecting View--> Show Closed Captioning (Ctrl+Alt+T).
Anyone been able to export to MPEG-4 pass-through movie with embedded text track QuickTime Pro 7 Windows?
Thank you!

Can anyone help with Quicktime Pro audio prob?

I've been trying to compress an audio/video file shot on my Cybershot so that I can upload on a contest website. Every time I copy into I-Movie, I have no audio (although it plays fine on my desktop). I was told I-Movie does not support muxed streaming. At Apple's recommendation, I upgraded to Quicktime Pro.
The audio and video both work fine when I play it in Quicktime Pro; but when I export it from Quicktime to either MPEG4 or Quicktime Movie, I get no audio. (Also, the audio setting area is grayed out.) Any suggestions? I need to send the file 320X240 around 15 mb by midnight tonight.
Thanks for the help...

Use the "Export to DV" option. (Any of the sub options will work.) Split into segments if needed for older versions of iMovie.

Exporting to .mp4 file using QuickTime Pro

Rather than use the Movie to iPod preset in QuickTime pro, I would like to export an .avi file to a .mp4 file using Movie to MPEG-4. I would like the resulting file to be encoded using h.264 video and to be 640 X 480. I want one file that I can include as an enclosure in the rss feed for my podcast that can be downloaded and played in both iTunes and on an iPod. So far, I have been able to create a .mp4 file that plays in iTunes/QuickTime but not on an iPod.
Would someone with experience in this please tell me which settings to use in the MPEG-4 export settings dialogue so that I get a file that can be played on the iPod.
The options are:
File Format (I chose mp4)
dropdown (I chose video)
Video Format (I chose H.264)
Data Rate (I know it's important that this not be too high but don't know what to put.)
Optimize For (download is the only choice for this option)
Image Size (I chose 640X480 VGA)
Preserve Aspect Ratio checkbox (My original video is 720X480. I don't think I should check this. I want to change the pixel aspect ratio to square pixels.)
using dropdown box (Letterbox, crop, fit within size) (only active when Preserve Aspect ratio is checked)
Framerate (I chose 29.97, which is the frame rate on the original .avi file)
Keyframe ( I set this to every 15 frames)

Thanks. I was aware of that information. But still am stuck on using QuickTime Pro to come up with a usable .mp4 file for the iPod. I think I am using the right settings, but it's still not working. That's why I included a lot of detail about the specific options in my question. Hopefully, there's someone out there who has used QuickTime Pro for this.
