No Audio When Converting Videos For iPod

whenever i convert video files for my ipod they do not have audio. i have tried several programs, and none work. i have read other discussions about this, and found that MPEG Streamclip worked for other people, however whenever i try to convert using this program, it says "Error: Can't Prepare The Movie" Can anyone tell my why i can't convert these videos? i cannot figure it out. thanks alot.

I am not sure what you mean when you ask what the "compression formats" are.The compression formet refers the manner in which the media was encoded and, by extension, how the media must be decoded. I.e., it determines which codec (encoder/decoder or compressor/decompressor) is to be used with the media file.
If you can tell me where to find those i could tell you what they are. I can, however, play the video in itunes, quicktime, and MPEG Streamclip.Simnce the files are playable in QT, the most common place to look for codec information is in the "Show Movie Info" window following the "Format:" entry. E.g., it might say:
Format: MPEG2 muxed, 640 x 480orFormat: Apple MPEG4 Decompressor, 320 x 240, millions
AAC, Stereo, 48,000 kHz
i also am not sure if there is audio in the source file.Do you hear any audio when the original file is played? If not and there is no audio track (or "muxed") information, then there may not be any sound for you to convert in the first place.
how do i find out if it is muxed?If it is "muxed," the format entry we say so. In this case blocks of audio data and blockes of video data are interspersed in a single data stream (track). This is the normal way MPEG-1 and MPEG-2 audio/video data is synchronized. In addition, these formats commonly lose their audio content when converted using QT Pro, iTunes, iMovie, FCE, FCP, or other QT based "frame-to-frame" synchronized workflow. (In the case of MPEG-2 in MPEG Streamclip or QT, the QT MPEG-2 component must also be installed in order to convert the video data alone.)
most of my videos that won't convert for an ipod are downloaded from the internet. how can i find out if they are corrupted or incomplete?Internet files should always be considered suspect -- especially if they come from a peer-to-peer source. Messages that indicated QT cannot open an otherwise fully compatible QT format is often the best indication that there is a corruption problem or that the files were improperly closed at one point or another.
most of my videos that won't convert for an ipod are downloaded from the internet. how can i find out if they are corrupted or incomplete?Normally ypu would post them to a web site or FTP storage area and post the URL. If files were downloadedd from a particular web site (e.g., a QT movie trailer), simply post the URL for the particular web page.

Got problems when converting video to 640*480 m4v

guys, I got compatibility issues when convert videos to 640*480 h264 m4v.
I tried MepgStreamclip, and the export to mp4 quicktime mov in Quicktime. ALL FAILED.
I followed all these 1.5mbps, 640*480, aac-lc requirements when did the conversion.However, my ipod will not recognize of the files.
I have also noticed that the "Export to Ipod" preset in Quicktime has been changed to 640*480. BUT, what keeps annoying me is the preset is so idiotic!! It ignores the source bps and simply converts everything to 1.5mbps. I got 25mb file after conversion as the source file is 11mb.
Could anyone kindly point out the Right procedure to convert video to ipod format Manually...... I want to have full control when I am doing this.
thanks a lot

any suggestions?

Audio problem when importing video files.

Hello everyone,
I just started using FCP X a few days ago for a university project and I seem to encounter an audio problem when importing videos in .mp4, .mov format or via the import from camera option.
Indeed I need to import videos in .mp4 and .mov format into FCP X. The import in itself is normal I can see my videos into the events/clips library and if I play them from the library I can hear the sound quite perfectly.
However, when I want to edit my videos and put it in the timeline, there is no audio. As a result I started to think that my videos could be the problem so I tried the option "import from camera" option using the Isight camera of my macbook pro but the same things happened. I could hear the sound from the events/clips library but not from the timeline (I can't see any audiowaves in the timeline).
I found a solution using quicktime and extracting the audio of the video in .m4a then importing the videos files and the audi files corresponding but it's a long process and a waste of time as FCP X should be able to import the audio of my video into the timeline directly. Especially if it can read it from events/clips library.
I hope I explained myself clearly and you could help me resolve my problem.
Cheers
Christophe
PS: I'm using FCP X version 10.0

Update to 10.0.5.
You have an incorrect setting when you edit. Try trashing your preferences. Post screen shots of your timeline and toolbar.

Audio delay when call is answered, CUCM 8.0

I have a client who is reporting an audio delay when a call is made to an external number. Call setup is fine and ringing begins immediately after the last digit is dialed. When the called party answers there's a 1 or 2 second delay before either party can hear each other.
Outbound calls are routed to a SIP trunk. I am suspecting that an MTP is required but checking that off causes all calls to fail.
I then discovered that the only MTP defined in CUCM is the default and this is in a different device pool than the SIP trunk with the delay issue.
Before I got through a possilbe hardware purchase (router, dsps, etc.) for the site with the problem I was hoping someone could confirm that this may in fact be the issue.
Thoughts?

Under older versions of CUCM, you can set that same parameter as a global Service Parameter for the CallManager process.You can try that. Newer versions pushed the setting down to the individual trunk level. Be aware the global setting will affect all calls on all SIP trunks, so test carefully after the change.

No audio when converting video for ipod 3rd generation

I read a thread that had not be answered regarding video to ipod that ends up with no sound. I wonder if anyone has found the answer to the problem. I have converted movies from imovie 08 and had no problems with sound but when I tried to convert a downloaded music video I only get the video and no sound.
Anyone have the answer to that one?
Thanks
Kevin

QuickTime expects video files with separate video and audio tracks, but many MPEG formats used a muxed (multiplexed) single track that contains both. Therefore, when you convert videos in iTunes to iPod format they only show the video and no sound since iTunes (really QuickTime) is not looking for the audio track within the video track and it gets lost.
iPod plays video but not audio of some exported files

One way to work around this is to use MPEG Streamclip to convert the files to fix this issue...

but there are other applications besides MPEG Streamclip you can try as well.

NO AUDIO WHEN CONVERTING VIDEO TO IPOD FORMAT

This is really ******* me off. My .mov's are being converted via QTPro to mV4 with no audio. Why does this have to be so f*ing difficult? How can I extract the audio and re-sync it to the video? I have a powerbook and have finalcut and logic express.

There's no problem converting to an actual file that iPod plays, it just doesn't add the audio to the new file. I hear that you have to have the video and audio file with some .movs (possibly with old codecs??) before you convert them to ipod format. So, I have to extract the audio from the .mov (probably with final cut) and then import the video along with the audio back into final cut and then convert to the m4v.
I just don't know why this process is so difficult, there should be a program that extracts the audio with video to the correct format. I've tried every program and with final cut so far and none of them add the audio to the final video.

Audio lost when converted to iPod

I have a video (48.4 MB mpg) that plays fine in QT and iTunes but when it is converted (with either) to iPod (24.2 MB m4v) using "Convert selection to iPod" the audio is lost but video is fine. Any suggestions. Thanks. Phil

Hi Phil. There seem to be some problems regarding the conversion of video files with muxed audio (i.e with audio embedded in the video file), and Quicktime does not support the conversion of MPEG-1 files. I have used the excellent (and free) iSquint to convert videos for my iPod with great success. There is also an application called ViddyUp ($9.95) which offers similar functionality, and can convert files with muxed audio.

Audio Delayed When Exporting To Camera

When exporting the movie to my camera, the audio is not quite synced with the video on the Mini-DV tape. I have determined the offset to be about 8 frames. If I then import that video, extract the audio, and then move it to the left 8 frames, it is then synced with the video again. If I encode the project with Toast after I have it synced, and then play the result on the Mac with the DVD Player, it is fine. But if I export it to the camera again, the audio is shifted again on the Mini-DV tape. I have a G4 dual 450 Mhz running OS 10.4 (the latest) with the latest version of iMovie and exporting to a Sony DCR-TRV900 via the firewire.

"..When recording it back to Mini-DV tape this way, is there a significant amount of loss of data even though it is coming over the firewire connection vs the normal export function?.."
No data loss, Gary. This is the proper way to export your edited movie.
You DO get data loss when transferring to a DVD, as a DVD is encoded differently from DV ..the MPEG encoding of a DVD involves compression of the data, leaving only information about the differences between frames of video, instead of keeping the content of all the frames.
You DON'T have any such loss when exporting ('Saving') back to miniDV tapes, as the exact same data which was copied from the tapes, when importing into iMovie, is sent back out to a tape.
There's no data loss, and there should be no audio delay. You can then import again from such a tape and there'll still be no loss. But re-importing from a DVD will produce data loss, as the decompression from MPEG to DV cannot completely rebuild all the data which was in the compressed MPEG data stream on the DVD.
So save your edited work back to tape, Gary, in case you ever need to 'reprise' it, and only create DVDs for sending through the mail, or to present your video with fancy interactive menus, or so that you can easily find particular 'chapters' in your video.

Missing audio track when importing video into Premiere Pro CS3

When I import my M2TS video into the editor there is no audio when viewed in the source. There is also no audio track when I drag a clip down to the timeline. Any fix for this?

I have the same problem with M2TS files in Adobe Premiere Pro CS4. The audio track is there - Adobe Premiere just doesn't recognize it. If you open the same clip in Nero Showtime, Corel Ulead VideoStudio, etc., the audio will be there. The audio is probably multiplexed.
I have been recording High Definition TV using the Hauppauge HD PVR 1212. About 15-20 % of the M2TS files recorded will be seen as video only clips by Adobe Premiere. The remaining clips will be conformed by Premiere and you will have a Dolby Digital 5.1 audio track. If you convert the video only clips to .MP4 and then re-import them into Premiere you will then have the Dolby Digital 5.1 audio track back and you're good to go.
I use either Xilisoft or Arcsoft media converters to change to .MP4 files. If you use Arcsoft you will have to render the clip. The files converted by Xilisoft don't have to be rendered for playback.

[SOLVED] ATI HDMI audio fails when playing videos... fine otherwise.

On a fresh install of Arch Linux, despite being an amateur at best. I'm using ATI HDMI audio using the open source driver, on GNOME 3. I'm switching to Catalyst after posting this to see if that might help, somehow.
After adding the radeon.audio=1 to the bootloader, audio on the system began working just fine as long as I restricted myself to audacious (haven't tried another audio player) or the system sound tests. When I try to use VLC, or mplayer2 for that matter, not only does it not play the audio associated with the video but NO audio will pass through the system at all. I have tried changing the audio source in VLC, although default should work... nothing works. Changing the audio in VLC will cause the system's audio to max out. Changing it back to something else doesn't help, but I can change the volume after closing the video programs, and after a few clicks it will go back to the "bloop" sound that confirms volume changes. Everything works fine again.
I have been at this all day and I am at wit's end. My google searches are getting way too long to be of any help. Any pointers or obvious things that I've missed in my caffeine haze would be greatly appreciated. Thanks!
...SOLVED by switching to Catalyst drivers from open source.

No sound when convert videos to ipod

i have bought quicktime pro, and i can successfully convert videos onto my ipod, but there is no sound on them. has anyone got a clue how i can resolve this?
thanks alot

No new "points" can be given as yours was just a tagged on response to an already answered question.
Muxed file formats (MPEG 1 or 2 and Flash) are intended for playback only. MPEG 1 or 2 require licensing agreements ($$) from the Moving Pictures Export Group (the people that make the file name MPEG) which would be passed on to all end users and Apple has decided against those extra fees.
Those are the "limitations" of the Apple software. It currently doesn't extract audio from muxed file formats and I don't expect any changes any time soon.
Dozens (hundreds) of third party software apps can convert your file and include audio. Many of them are free.
MPEG Streamclip offers both a Mac and Windows version. It can convert your .mpg file with audio. It even has a "one button" export feature to meet the specifications for iPod files.
Now you really know the limitations of the software and the reasons for them.
Get some third party tool to make your iPod files from your muxed file formatted ones.

ibook Mac OS X (10.3.9)

Where are the videos from? are they from a creditable source or from an illegal downloading site such as limewire. most of those videos are not in the correct video format to begin with so apple itunes will not recognize them and convert them. The best way to convert video is to rip your own dvds or home movies and put them on your computer then ipod. There is at least one way on each operating system (windows and mac) to rip your own dvds and then transfer them to itunes and finally put them on your ipod. A mac is the easiest of the two ways. If you have a mac, then you download a program off of the web called handbrake. Simply "google" >handbrake rip dvds< and its homepage should pop up or try <a class="jive-link-external-small" href="http://">http://handbrake.m0k.org). Handbrake allows you to copy and convert your dvds to ipod format. On a windows operating system the most effective way I have found to rip my dvds is quicktime pro($25-$35). You can buy it at quicktime's website. It basically does the same thing as handbrake. I, myself, have simply converted some videos, like sports shows and commercials, to ipod format using itunes and both the video and audio worked fine.
If you have any ?'s just reply back
I hope this helps!

Audio Dropout when playing video

Hi,
I have been experiencing audio dropout when playing Youtube or any kind of video. I am currently using an audio interface (Focusrite Scarlett 18i6) connecting to my speakers. This has been going on for some time.
OSX 10.10.2
iMac (27-inch, Late 2013)
Processor 3.5 GHz Intel Core i7
Memory 32 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 775M 2048 MB
Storage 500GB Flash Drive
Please help!!
Thanks and Regards

If you have menu's etc then the problem isn't one of video mode settings or indeed
connection/cabling.
Agreed.
Are the problems consistent (ie always the same files, or does a file sometimes play and not other
times)
Yes, also the intro screen doesn't appear at startup. (audio does). NitoTV (which uses mPlayer) works fine. Perhaps QuickTime is corrupt on it?
Have you played these files on the tv before.
Yes.
Do they play in itunes.
Yes, they play fine in iTunes - audio and video.
Thanks,
James.

No sound when converting video to ipod

after i convert video for ipod playback using quicktime the file has no sound???.....

it's probably best to check to see if the source files for that video are "muxed". for some more info on that, see:
