Audio lost from dragging MPG file?

I have some MPG files, 10 second or less clips from our Sony digital camera, and I can't figure out how to get the sound into iMovie. All I want to do is rotate the mpg 90 degrees, and I figured out how to do that with Simple Rotate from cfx, but now there is no audio. If I go to "Import" from iMovie, the raw MPG files are dimmed out so I can't open them. If I drag and drop the clips, they are there but there is no sound. And if I try "Extract Audio" iMovie crashes. This is iMovie 3.0.3 on a laptop running 10.4.5

Hi Sean - welcome to the forum!
MPG files have to be converted to DV for the audio to be heard in iMovie. iMovie is designed for that format, not MPEG. Have a look here:

How to extract one of several audio tracks from a .vob file?

Hi guys,
hope you can help me, i'm looking for a solution for hours now but can't find one.
I would like to know how to extract one audio track from a .vob file when there are different tracks/languages on the dvd? Media encoder does it very well, but i can't find the option for choosing the right audio track/language for extraction. Please help
Kind regards
Alex

This is because the OMF specification requires mono audio files
It really depends on what you are trying to do with the two tracks as to the best answer as far as 'grouping'
You could select all the clips on both tracks and right mouse click and select 'group'
You could send both tracks to a bus
You could export the two tracks to a stereo file and bring that back into the session
Lots more things I'm sure but a little more detail as to what you are trying to do would help

2nd Audio track from merged .m4v files does not play on iPod Touch

I used Handbrake to encode two .m4v files of a concert DVD that spans two DVDs. I then took those two files and combined them into Quicktime Pro to create a single .m4v file. The file plays fine in QT but when I transfer the file to my ipod, only the first audio track (from the first file) plays. Once the video from the second file plays, the audio is silent. Here's what the movie properties look like:
Enabled Name Start Time Duration Format
====================================================
Y Video Track -- 0:00:00:00 -- 2:21:53:90 -- H.264
Y Audio Track1 -- 0:00:00:00 -- 2:21:53:90 -- AAC
Y Audio Track2 -- 1:27:28:87 -- 0:54:24:02 -- AAC
N Text Track -- 0:00:00:00 -- 2:21:53:90 -- Text
Any suggestions?
Thanks,
Dan

So basically, anytime I combine more than one mp4 file in QT7 Pro, it will always create multiple audio tracks when doing a simple "save as" (vs. export as)
Not exactly. QT has it own set of rules. As you noted, the video track had no problem merging into a single track. This would not have happened if you had merged video compressed differently or added an image/stretched image sequence. Not knowing your specific work flow or settings, I hesitate to make any claims here. Frankly, when merging audio, I normally prefer to use GarageBand when I want to create a single master audio track and still retain control of the other tracks for mixing purposes. However, I could just as well have exported the audio in the original file using QT Pro to a single audio file and used that audio track to replace both original tracks keeping both the original video and chapter tracks. It is all a matter of which work flow you consider easiest for a particular job or project.
If I've exported out my chapter file as a plain text file, how do I go about reintegrating that withing the final mp4 file using QT?
http://www.apple.com/quicktime/tutorials/chaptertracks.html
The above link is a somewhat old tutorial explaining how to create a chapter text track from scratch. Since you already have the chapter track, just refer to the steps indicating how to add the text file back to your main movie file. (Ignore the step that says to set a "Preload" option as this pop-up has been removed.)

Audio lost from Keynote 09 import to iPad

Audio missing from old .mov files

Recently I noticed that ALL of the audio from an entire folder of .mov files has disappeared. Video playback is fine. I tried to export from Quicktime to experiemtn but it suggests that the file is corrupt and can't be exported...but all of them? Files are being kept on external drive. Could Lion be causing this somehow? Any ideas how to retrieve the missing audio?

Copy (drag and drop) one of the files to your Desktop and test again.

No audio output on a mpg file

Hi all,
i recorded a TV show from a isdb-t signal using a usb stick. The stick comes with a windows software called Blaze DTV 6.0 to scan the digital channels, and to record the shows you are watching.
The recorded file has an .mpg extension. It plays correctly from inside the software, but so far i couldn't play it anywhere else properly. It shows the video properly, but i can't hear any audio.
Here's the media info for the file:

Does anyone has any idea as to how can i play this file properly on my mac? I'm running out of ideas here...
Thanks.

Unfortunately... The media app which recorded the file is the only one who is playing the audio correctly... And does not have an option to convert or export to another format. Even all other media apps on windows are unable to play the audio properly, so I'm lost here. I can't believe there isn't an app capable of decode this.
Object here is to avoid conversion by export but rather to save the audio and video data in its current compressed state to a file type that is compatible with the encoded data if at all possible. I would normally try the VLC player to see it could play the file. If you have already tried that and it didn't work, then I would be reduced to simple trial and error tests. Assuming none worked as you indicate, I would probably move on to conversion apps like HandBrake or FFmpegX/FFmpeg depending on your operating system. Other than that, I am out of ideas.

No video (black), audio only, from imported .mov files

Bear with me while I explain the whole process to get where I am, which is that in FCE, I am importing .mov files and they are completely black, no video, just audio. When I bring a clip into the timeline and try to render even a small clip, it is still black.
I'm not well-versed in video so please bear with me:
Steps:
1. I received large video files from a videographer
2. the large files could not be imported or played in FCE
3. downloaded HandBrake converter and began converting files. Kept them at the same size, but they were then renamed .mov files.
4. When I open them in QuickTime, they are black - no video. But when I see them on the drive and press spacebar in 'finder' to play them, I can see the video.
5. When I import them into FCE they are black - no video - just audio.
FCE is currently set (in Easy Setup) to: AVCHD-Apple Intermediate Codec 1920-1080i60
Any help would be greatly appreciated. I tried converting one file to mp4 and it works fine in FCE, but this takes a long, long time to convert.
thanks
There is a 2nd issue that may relate to this: I am trying to import JVC .m4v files and I am getting "File error 1 file(s) recognized, 0 access denied, 1 unkown". These files CAN be opened in Quicktime.
FCE HD 4.0.1
Mac OS 10.6.8

I'm having similar, but slightlly different issues.
I have been using FCE 4 on Mac OSX 10.7.5 with Quicktime 10.1 (501.29).
I convert my footage in Mpeg Streamclip (GREAT free program) and set the files to the Apple Intermediate Codec. This makes them work really well in my timeline and I don't have rendering issues or problems.
So, my problem comes when I File/Export/Quictime Movie.
The original file plays fine, but they're 2-3 gbs each, so I put them into Quicktime to convert them to a webfriendly size, but every single time they come out as an audio only file. GRRRR!
Any help would be greatly appreciated. Maybe I'm missing something stupid.
Thanks so much for your help.
Sincerely,
Steve

How to group Left and Right audio tracks from a .OMF file?

Audio extraction from 400+ QT files with between 1-8 channels

Hi there,
I need to extract all the audio channels individually from more than 400 QT files, with the number of channels ranging from 1 to 8.
Do you know of any script or automator action out there which could help me? Ideally I want to extract the audio as AIFF.
I've seen these, but as far as I can tell they won't extract each track/channel on its own:

Thanks for any help.
Macbook Pro Mac OS X (10.4.8)

I have brought my export back into PP and I don't see audio. As you suspect, my export settings were incorrect. I failed to set Channels to 8 Channel; it was set to Stereo. I am creating a new test file for the broadcaster.
Thank you!

Color swatch lost from client's file

A client submitted an indesign file which she converted from cs7 (pc) so I could open in cs6 (mac). She insists she created a certain color swatch in her palette but when I opened her file, the color was not in the palette.

dkukar wrote:
Can you describe or send a link as to how to save the save the swatches?
Use the dropdown menu from the Swatches panel and select 'Save Swatches'. This would also be the same location for loading them once the client saves them.

Audition jumps time code forward on audio extracted from a .mov file

I have a video file with a starting time code of 10:41:17:23.   I open this file in Audition, apply a noise reduction effect, and export the file out as a new .wav file.
However, instead of the audio file having a starting time code of 10:41:17:23, the time code on the file starts at 10:41:34:20.
So, the time stamp has jumped forward 16 seconds, 21 frames.   And, the jump amount is not consistent. Another file had a 37 second plus jump.
Since we are talking about the STARTING time stamp, in all instances, I believe frame rate, codec, etc. are immaterial unless someone can convince me otherwise.
If I was dealing with different frame rates/codecs/etc., I could understand the time code being out of sync later in the file, but I cannot understand why it would be out of whack at the very start of the file.
Anyone got any ideas on possible cause/cure?   It's a pain having to manually search for the audio file for the correct location instead of being able to just punch in the same time code the video uses.

OK. I double checked and the timecode showed 23.976 for my test .mov file in Premier Pro, with a sample rate of 48,000 32-bit.
I made sure my timecode default was set to SMPTE 23.976 in Preferences/Time Display in Audition. I then opened the .MOV file in Audition, let it split the audio out, and moved the audio to the editor panel.
The timecode in the audition editor panel shows 23.976. The preview panel also shows 23.976.
For what is worth, the "time code" block of blue numbers in the lower bottom left of the Audition preview panel shows 00:00:00:00.    I believe this is because the primary "Time Code Start" field in the Canon 70D .mov format files is empty and the camera is putting the time code in the Alternate Time code fields.
I then opened the Effects drop down menu and applied Noise Reduction/Restoration, option Adaptive Noise Reduction, using the preset "Light Noise Reduction."
After the apply completed I saved the modified audio file with a format of Wave PCM, leaving the Sample type at the default of 48000 HZ Stereo, 32-bit and Format settings of Wave Uncompressed 32-bit floating point (IEEE).
I left the box checked next to "Include Markers and Other Metadata." And, clicked OK.
I then went to Premier Pro and opened the just saved audio file. The starting time code on the file is 10:38:52:22.   This does not match the starting time code on the original MOV file which is 10:38:14:10.
So, based on my limited understanding of both Premier Pro and Audition, I am gettting the exact same sample rate settings and time code settings all the way through the process in both Premier Pro and Audition up to the point of saving the modified file out of Audition. It is at the point of saving that things get changed.
Charles asked me to post screenshots and a sample file somewhere. I am working on doing those tonight. I just have to figure out where to post them. My original test files were quite large, but I got the same results with a 2 second file in my second test, so I'll post those files someplace.

[HELP] No audio track on imported MPG file into FCP

I am trying to import a 1hr 50min mpg into FCP. If I open it in QT or even in Windows Media Player on the PC, it opens fine. However, when I import it into FCP, I get the video track, but no audio tracks. I am still rather new to FCP, so I am sure this is a simple solution. Please help.
Thanks...
Dave

Welcome to the forum, David. As Wes said, you need to DeMUX the MPEG. There are a few ways to do this. MPEG Streamclip is one, bbDemux, another is DVDxDV.
Good luck

Re: How to split audio alone from a video file.

After have configured the processor and before calling the realize method you have to setEnabled(False) the video track.
Processor proc = ....
proc.configure();.....
//if the video track is the second:
proc.getTrackControl()[1].setEnabled(false);
proc.realize()....
In this way, in the multiplexing phase, the video track will be ignored.

Due to DRM, you cannot burn purchased videos, except for backup on Data CD/DVD.
The only way to separate the audio is to use a capture application like Wiretap Pro or Audio Hijack (Pro). Latest versions can be found on versiontracker.com.
Hope this helps.

XMP metadata lost from PNG files after saveing

Hello,
i am using Photosop CS3 SDK. through my plug-in I put some metadata in the file using XMP SDK 4.4.2.
For PNG files, if the file is modified and saved, all the XMP metadata is lost from the file.
The following steps are being done.
1. Put some metadata in PNG file using SXMPMeta::SetProperty and SXMPMeta::AppendArrayItem
2. modify the file (changed brightness, contrast, flattened the image).
3. Save this file.
After saving all the xmp metadata is lost from the PNG file. This works for all other formats.
What can be wrong that I am doing?
Is there any other way to put XMP metadata in file?
Thanks,
Hitesh

That's probably because PNG doesn't save or read XMP metadata.
There really aren't standards for metadata in PNG. (though a few products have tried adding it in ad-hoc ways, without documenting their efforts)

MPG to Final Cut Pro , convert mpg files to FCP freely

Why need to convert/import MPG files to Final Cut Pro?
Final Cut Pro is the premium choice for any Mac video editing, and it is widely used by Mac users now.

If anyone comes across the situation, the best solution is to get aids from MPEG/MPG to FCP converter for Mac, which can help you to convert MPEG group files to FCP compatible video format and then files can be easily imported for editing job.
As we know that Final Cut Pro don't natively support MPG, MPEG, MPEG-1, MPEG-2 files, it can import MPEG-4 files (but need to be rendered once you place them on your timeline) and MOV files (without rendering). Therefore, to import MPG to Final Cut Pro directly, the best way is to convert MPG to Final Cut Pro supported Apple ProRes MOV files.
How to convert MPG to Final Cut Pro(fcp)

Import unsupported MPEG-1 or MPEG-2 to Final Cut Pro 7/X, Final Cut Express
Summary:If you are looking for the best way to transcode MPEG-1 or MPEG-2 videos to ProRes MOV for FCP 7/X and FCE, you can follow this post, it has offered best solutions for editing MPEG videos on Mac in Final Cut Pro 7/X, Final Cut Express.
Cases:
The following are two problems when some users import MPEG-1/MPEG-2 to Final Cut:
"I am trying to import MPEG-2 files into Final Cut Pro X. I have the raw files from a Sony Handicam HDR-SR5 as well as raw files from an Sony Handicam MDR-CX560. These files were recorded as MPEG-2 files and copied from the camera hard drives (entire folders were copied containind the MPEG-2 fies) to a local hard drive on my computer. Final Cut Pro X does not recognize the files and will not import them. I have tried to use Compressor to conver the fies. I am using the very latest version that touts being able to export to Final Cut X format. I don't see that option anywhere in the settings."
Question:
Is there a way to get MPEG-1 or MPEG-2 files into Final Cut Pro X without having to convert them?
Answer:
Don't try to work with (highly compressed) MPEG 2 in FCP X. Use software to convert to ProRes 422 first, it's best codec for final cut pro or final cut express. Life will be much easier for you if you do. ProRes 422 is roughly between 5 and 8 times bigger than native camera footage - sometimes as much as 10 times, I believe, but it's well worth it for editing, effects and playback quality. The time required depends largely on your processor power but 30 mins sounds realistic.
Software you need:
Pavtube HD Video Converter for Mac
This software can convert MPEG-1 or MPEG-2 to Apple ProRes 422 codec for Final Cut Pro, Final Cut Pro 7, Final Cut Pro X or Final Cut Expr editing without rendering.
Step by step guide:
1. Download and install the best MPEG1/MPEG2 to ProRes Converter and launch it to add your videos to it.
2. Choose output format. Click on the “Format”> Final Cut Pro, Apple PreRes 422(HQ), Apple PreRes 422, Apple ProRes 422(LT), etc are all the proper choice for you.
3. Click "Settings" to adjust the parameters as you want, like Video Codec, bit rate, frame rate, Audio codec, sample rate, bit rate, channels. Set the video frame rate as 30fps, video size as 1920*1080 will be better.
4. Click Convert button to start MPEG-1 or MPEG-2 to Final Cut friendly Apple ProRes 422 for native editing on Mac OS X.
5. When the conversion ends, you can run the Final Cut Pro and click File --> Import --> Files to import the resulted MOV files and edit them in FCP easily, you can follow this import video to fcp guide.
From the steps above, I think you got the point to convert and import MPEG-1 or MPEG-2 files to Apple ProRes 422 for Final Cut editing, please have a try, this software will solve you MPEG-1 or MPEG-2 importing and editing problems, and then you can import and use your MPEG-1 or MPEG-2 in Final Cut Pro 7, Final Cut Pro X or Final Cut Express on Mac without any problems.
