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.

How to split words alone from text ?

how to split the text from a text file even with out the special characters to be stored to DB.I have seperated words using split.but it is having special charecters. is there any option with split to give special characters too as delimiters (i mean multilple delimiters).
Or any other way to get the words and integers alone?

gs_ravishankar wrote:
i think his problem is he has a file which has some text row wise, this text contains different special characters.
and his job is to read the text from the file and remove all special characters in the text and store this string in DB.
if this is the case,
i would suggest to get the ascii value range of all special characters and then write a condition for it.
may be something like this
if(text.chatAt(i) >= 12 && text.charAt(i) <= 45)
text.replace();Jeebus, have you ever heard of regular expressions?

How to split Large mp4 and AVI video files to smaller scenes

Hi All
I’ve been looking into how to cut-up large files ready for import into CS4. So far all I can find are the usual suspects that only lets you cut a section from a file. Dose anyone use any software that enables you to split a large video file (MP4, AVI and so on) into say 20 sections all in one hit?
I do a lot of HD onboard cams, so the video is set to fire and only shut off when the run has finished. I then end up with about 60 percent of the file (in diferent parts) I need to trash.
Any help or advice would be much appreciated indeed!

Maybe, but maybe not. I use DigitalMedia Converter to convert to DV-AVI Type II's (I'm only doing SD), and it has a Split function. However, I have never used that, so do not know how well it might work for your needs, if at all. I just do not know. I believe that Deskshare has a user forum, and that might be a good place to try, after you've looked down their FAQ's.
I hope that others will have a definitive answer for you, with iron-clad suggestions.

How do I stop iTunes from duplicating video files?

For some reason unknown to me, iTunes duplicates the video files when they are added to the library.
For music, when I add these to the library, the files stay on the external drive, and they are listed in the library.
However, I now moved my video files to an extrnal drive, but when I want to add them back into my library, it wants to copy all of them (the full file) from the external drive to my itunes folder. I moved them off of the computer hard drive because they take up too much space. I don't want them here, but I do want them in the library so I can select and sync them.
How do I add these videos to my itunes library, but keep the actual files on the extrnal drive?

Turn off the option "Copy to iTunes Media folder when adding to library" under Edit > Preferences > Advanced.

How to take a picture from a video file

Is there a way to take a picture of video clip from the web? I am trying to pull a pic of a video file, a single frame. Is there an app, or a really easy way to crop and save a photo to my library?

Pause the video where you want the clip then use shift+command+4 to get a cross hair selector and drag that across the part of the screen you want to capture, it will be saved as Screenshot_date_time to your Desktop

How to burn audio only from a Video Single

I have a video single as part of personal mix in itunes. When I try to burn the mix, all of the tracks burn except the video single. The dialog box says that burning is disabled for this track. I assume this is because the video content is imbedded in the file.
This is somewhat confusing as the track was noted as a single and separate video at the time of purchase. Is there any way to convert the content so that it can be included on an audio CD?

Hi,
I have a jpeg movie file 60 mins long and a text file tell me five time-lines for breaking the movie. For example, break the movie at 10:21, 16:05�
The final output should be five small jpeg movie files. Each file contains a 90 sec (30 sec before the break time and 60 sec after the break time).
Do you know any java library (jar) contain the library that can help me on programming this? Any existing source code? Any SDK for a movie editor can do that?
Please help.
Thanks
Kenny

How to split audio from video clip

Title said it all.
Thanks

Command + L does nothing. Any other ideas? What I saw in a tutorial was that they selected a clip, then did some key sequence and it split out the audio track from the video. The audio then showed up as a green section right below the video track. They were doing this to delete the audio. They would split it, then select the audio track, then delete it. I realize I can drop the audio level, but this seemed like an interesting option.
Thanks

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

How do I seperate the audio track from the video and save it to a CD in Premiere Elements 13?

How do I seperate the audio track from the video and save it to a CD in Premiere Elements 13?

Binbashi
You can separate the audio track from video and save it to a DVD disc within Premiere Elements but not a CD disc.
To do save to the audio to DVD disc, you do not have to separate linked audio video, just use the export Publish+Share/Computer/Audio and set Presets to the wanted format (AAC, AIFF, MP3, or Windows Waveform (WAV).
You will not see Audio in the choices since it is at the bottom of the list of choices under Publish+Share/Computer/. You will need to use the thin scroll bar to the right of the choices to scroll to it.
If you need information on selective export of Timeline content when dealing with more than just this one file on the Timeline, please let us know. If you are trying to produce a CD for listening in car or CD player elsewhere, please let us know.
Looking forward to learning of your results.
Thank you.

How to delete Audio Lectures from iTunesU

I Just wanted to ask How to delete Audio Lectures from iTunesU?

If you are using automatic syncing, you must have set up the shuffle's Books screen in iTunes, to tell iTunes how to sync audiobooks to the shuffle. You go to the Books screen by selecting the shuffle in iTunes, to see the row of "buttons" that starts with Summary. Click on Books there...
If you set up that screen to sync audiobooks to the shuffle, you just need to uncheck the books you no longer want on the shuffle, and click Apply.
If you loaded the shuffle using the manual method (drag and drop items on the shuffle in iTunes), please post back.

How do i move clips from home video to roll?

how do i move clips from home video to roll?

Ahh, Ok. I actually had to go to Lynda.com to watch a training video of this highly bassackwards maneuver, but now I have it. In other words, while the intuitive thing is to make a new event to hold the clip you want and then open the old event and drag the clip into it's new event, the only way to accomplish this maneuver is to NOT create a new event, but rather, go to the clip AFTER the one you want to move, select it and then Right-Click on it and select SPLIT EVENT BEFORE SELECTED CLIP (or go to FILE>SPLIT EVENT BEFORE SELECTED CLIP). Then you wait a few seconds while the program thinks a bit (no feedback it is doing this - just a pause) and then it automatically creates a new event with the clip you wanted. Now just double-click the new event and name it something meaningful.
Thanks for your 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.)

How can I plott data from a text file in the same way as a media player using the pointer slide to go back and fort in my file?

Please, can some one help me?

Plotting from a text file like a media player example.jpg ‏61 KB

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes
