No audio in video conversion?

I have QT pro with mpeg playback component and I want to save the files for my ipod but when ever I do there is no audio. So I went to convert to mpeg4 and went to options and it says there is no audio steam to convert. It does it with any files I try and covert. Any idea what is wrong? I have a g4 1.33 iBook with 1gb ram and the latest build of 10.4

QT does not support the export of audio from mpeg-1 or mpeg-2 files: QT Mpeg Limitations
You can use this freeware to convert both audio and video to other formats: Mpeg StreamClip
Search the "Quicktime for MacOS" group using "iPod" as the search key for other tips on conversion to formats to play on an iPod. There has been very active discussion of that topic over the last 3 weeks.

Losing Audio in Video Conversion m2ts mp4

I am using a video importing device and software that creates a "m2ts" file.   I can play the created "m2ts" file perfectly using VLC.
However, neither QuickTime 7 or QuickTime 10.3 will play this file.   When I tried to use MPEG Streamclip I was presented with a pop-up suggesting I need to purchase an additional plug-in, (which I am happy to do). It suggested I go here to purchase. http://www.apple.com/quicktime/mpeg2
I tried that, but was redirected here http://www.apple.com/quicktime/extending/components.html
I have no idea if the software I need is at this redirected website.
The plot thickens.   The importing software has the ability within it to convert video file to a mp4.   I tried that because I have found mp4 to be more compatible.
Unfortunately, I lose all audio (the video is perfect) when I try MPEG Streamclip or VLC. With QuickTime 10.3 I get perfect audio and video. So, I drag the mp4 file into iMovie 06 (aka iMovie HD) and it begins converting into something. When the conversion is complete the audio is gone!
I have dumped many mp4 files into iMovie 06, and never had a problem until now.
Thanks for reading, suggestions appreciated.

I thought I would report my progress. ( I have sound now, BUT !! )
I purchased a video conversion program from the Mac App Store.   It is called “AnyVideo converter HD". It is well reviewed.
So, I dropped in my "m2ts" file. I set the conversion to "Computer MOV 720p HD". "AnyVideo converter HD" converted a 1 minute video in about 15 seconds to a "mov".   The converted file had excellent picture quality and sound, it played perfectly using QuickTime.
Then the trouble started. When I dropped this 60 second clip into iMovie 06 (set for 720p) it's conversion process took 35 minutes ?!?!   The result was flawless! However, a two-hour video conversion would not be complete until about the time Capt. Kirk joins Starfleet.

Audio and video out of sync when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.

Quicktime Video Conversion Not Preserving Multiple Audio Tracks

Hi All,
I'm trying to convert a H.264 video file to a ProRes MOV using quicktime pro 7.
This is a video file that was created using Handbrake.
In Handbrake I am able to rip several audio tracks from a VOB. In this case I need to rip both the 5.1 audio and 2.0 audio. Instead of splitting this up into separate exports, I can attach both audio tracks to the H.264 mov. I can view and edit them in the Properties window of the video in quicktime.
So what I'm starting with is a video file with two Audio tracks:
5.1 Surround: C,L,R,Ls,Rs,LFE + 2.0 Stereo: L, R
What I'd like to do is unite the two audio files to create an 8.0 track: L,R,C,LFE,Ls,Rs,Lt,Rt
By changing the naming of the stereo track from L,R to Lt,Rt in the properties windown, an option appears in the audio export settings to use the SMPTE DTV audio output (L,R,C,LFE,Ls,Rs,Lt,Rt). But when I use it, assuming it will recognize my naming structure and rearrange the tracks according, the export results in a stereo file.
What am I doing wrong?? All logic makes me assume that this should work...
I should note that when I open the H.264 in quicktime the 5.1 audio track is not enables (or clicked on) in the properties tab. I must turn it on for quicktime to recognize it in the inspector window. However, when I try to save the video it requires me to save my file in an MOV container.
When I try to simply export the file as a 8 discrete channels, it will export with 8 channels, but the first two are a stereo pair and the other 6 are silent tracks.
The only way I've found to keep these audio tracks together is to extract each audio unit separately (5.1 and 2.0) and then add one of the audio tracks to the other using the copy and "Add to Movie" feature. This is not my preferred workflow since I'd like to keep the audio and video together. I'm creating a workflow that will be repeated several times so the more I can streamline this process the better.
Please help. Any ideas would be great.

I don't think Quicktime Pro is able to export individual audio tracks. It sounds like Handbrake create an AC3 sound track and a 2.0 channel stereo track. I don't think iMovie will handle multi-track audio and Final Cut Pro X won't let you assign audio channels to individual outputs.
If you have the original VOB file, DVDxDV Pro will break it out to individual audio channels into separate AIFF audio files which you can then import into Final Cut Pro 7 and remix the audio that way.

[solved] Video conversion problem: Mencoder on Arch versus Windows XP

I have a cheap portable video player which (according to a supplied Windows software configuration file) requires any video to be converted (say from a YouTube .flv) using a command line like:
mencoder myfile.flv -ofps 15 -vf-add scale=160:128 -vf-add expand=160:128:-1:-1:1 -srate 44100 -ovc xvid -stereo 0 -xvidencopts bitrate=300:max_bframes=0:quant_type=h263:me_quality=0 -oac lavc -lavcopts acodec=mp2:abitrate=128 -o myfile.avi
If I do the conversion on Linux - my fully-upgraded Arch - the resulting .avi file has the audio and video out of sync when played with Mplayer (on Linux and Windows), and no audio at all when played with Vlc (on Linux and Windows). But if I do (supposedly) exactly the same conversion using Mencoder on Windows, the resulting .avi file plays perfectly on everything on both Linux and Windows (and also the portable video player).
Here's the version information for the Mencoders being used:
Windows: MEncoder Sherpya-MinGW-20060312-4.1.0 (C) 2000-2006 MPlayer Team
Arch: MEncoder SVN-r32492-4.5.1 (C) 2000-2010 MPlayer Team
I'd be grateful for any ideas as to how to make my Mencoder conversion work as well on Linux as it does on Windows XP! (Or is there something wrong with the way I'm playing the file with Mplayer and Vlc on Arch?!)

Aha! I think I've cracked it, but using ffmpeg instead, with options prompted by this blog post:
ffmpeg -i infile.flv -r 15 -vcodec mpeg4 -vtag XVID -s 160x128 -aspect 4:3 -qmin 3 -qmax 5 -ar 44100 -ab 128k -ac 2 -acodec mp2 -g 1 outfile.avi
This seems to work everywhere, and the writer specially notes that:
The most important option is the -g 1 to force every frame to be a keyframe
which may well be where my conversions were going wrong. So I'll mark this as 'solved' even though mencoder is still a mystery, but I have learned to keep Vlc up my sleeve, so thanks for that tip again.

ZEN Vision M 30GB Video Conversion problem: black scr

My husband cannot display any video on his ZEN Vision M 30 GB. Any video converted comes over with ONLY audio, black screen (? no video display )This happened with the original firmware and software. I updated firmware and did all available software updates; no change. I had a previous ZEN Vision M 30GB, which did not have any problem with video conversion and display.Are there any known problems with specific Media Player versions, or QuickTime ?which may be a potential cause of this problem?( I have heard that this product works best with Media Player 9. )Anyone had similar problems, or have any ideas?Thanks,Ravenquille

Problem apparently solved: Last night, I downloaded and installed the free program, SUPER. My husband has not had a problem so far; been working beautifully! Ravenquille

Audio and Video out of Sync after Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.

Audio and video out of synch on export

Hi,
I've searched the forum for this. I have a movie in FCE 4 in which the audio and video are in synch in the time line. The audio was recorded into Logic at 96, noodled, passed into FCE at 48 and then had to be lined up with the video. Then when I go to export, the resulting QT movie is out of synch, the audio now about one second before the video. I'm using QT conversion. My compresson is H.264, quality best, frame rate 30, multi-pass, 640 x 480, format AAC or linear PCM, various sample rates, stereo and mono etc. I've tried various other settings for export, but the problem remains.
What am I doing wrong? Many thanks for any help,
Ray

Hi,
Thanks for the reply. I think you're on the right track. I want the best sound possible, so I record into Logic, knowing I'm going into FCE I record at 96 so an even multiple down to 48. I think a .wav file though, and maybe that's the problem. Into FCE, but other audio there as well from the camera mic, and which I occasionally include in the sound track for ambience. All of this noodled a fair amount and then exported, the intent being to end up in 44, as it will be uploaded to youtube. I switch to 16 bit out of Logic, but the aiff vs wav may be the problem. Do think there might be a better way to do this?

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.

Hotshot video conversion resolution? No full screen ever?

I have the Pantech Hotshot. The screen resolution of the phone is 400wide x 240high. When I convert a video to that resolution the phone always reduces it to 320 wide instead of filling the screen to the 400 wide and makes the 240 high even smaller. If I convert the video to a larger size it makes the video on screen even smaller. The only video resolution that works decent is 320x240 which fills the screen top to bottom but leaves black bars right and left. If its the phone software that's doing it than what's the point of having a screen 400x240 if you can never view a video in that screen filling resolution? And the video player has no option to zoom or fill the screen. What is the best resolution to convert a video to view on this phone to fill the screen completely like every phone I've ever had was able to do? Thanks

"The screen resolution of the phone is 400wide x 240high.

I think you have not found the solution to your situation. We have a non-smartphone (Samsung u370) that, like your phone, has a screen resolution of 400x240 and, like your phone, seemingly won't play a video at the correct resolution when the video is a resolution that exceeds 320x240.
On this u370 phone while playing a video, there are icons on the screen one of which looks like an "X" with arrows at the end of each of the ends of the "X". Tapping this icons causes the video player to expand the video so that now it's playing at the full horizontal resolution of 400.
The video player on our flip phones works the same way. Our LG vx8370 has a 320x240 screen. When I play a 320x240 video, initially the video players plays the video at a resolution of 240 x something. When I push up on the directional pad, then the phone expands the video and then plays it at 320x240.
One more thing. My experience on two different Verizon non-smartphones is the same when it comes to playing widescreen videos -- when I play a video of a resolution such that I have to select the option to expand the video so that the video is playing at the full horizontal resolution of the video, the video player won't show the correct vertical resolution of the widescreen video. Instead, the video player stretches the video to fill the vertical resolution of the phone's screen. While that is tolerable to me for a 16x9 video, my preference is that I find a stretched 2.35:1 video to look unwatchable. The only way that I can preserve the aspect ratio of the widescreen video is to use a video conversion tool that lets me pad the video with blank lines. FFmpeg and mencoder are two tools that have this padding option. So this is what I came up with. Suppose I have a 16:9 widescreen video. The video would need to be about 400x224. Since the video player software on the Verizon non-smartphones will play incorrectly by showing a video stretched to fill the whole screen, I'll need to use the padding command in ffmpeg and add 16 blank lines -- 8 lines above the video and 8 lines below the video. The ffmpeg command for that is
scale=400:224,pad=400:240:0:8
ffmpeg will scale the video to 400x224. The pad command tells ffmpeg that the converted video will have a total of 240 vertical lines of which 224 are the video and 16 of which are blank lines. The "8" tells ffmpeg how to center the video -- there'll be 8 lines above the video and 8 lines below the video.
Since ffmpeg uses a command line interface, two free graphic user interfaces for ffmpeg that I like are Avanti and Pazera:
http://www.videohelp.com/tools/Avanti
http://www.pazera-software.com/products/audio-extractor/
Pazera uses an older version of ffmpeg which can be updated after installing pazera by, if I remember correctly, just deleting the older ffmpeg file and replacing it with the new one.

No Audio - Converted Video

I have MPG videos with video and audio, so I converted using iTunes Convert Selection for iPod and bought QuickTime Pro 7.1.5 and converted using Movie to AppleTV option. In both instances, the resulting movie has no audio. If I play the original in iTunes, it has both video and audio, but won't sync to AppleTV, so I convert, and now it will sync, but no audio using either method...iTunes or QuickTime Pro. Any suggestions? Thanks!

have MPG videos with video and audio, so I converted using iTunes Convert Selection for iPod and bought QuickTime Pro 7.1.5 and converted using Movie to AppleTV option. In both instances, the resulting movie has no audio.This is normal. At best, "muxed" MPEG-1/MPEG-2 files are only playback compatible with QT/iTunes. The former are based on the spatial synchronization of audio and video data by interspersing akternating blocks of each in a single data stream. QT, on the other hand, is based on "frame-to-frame" temporal sunchronization of audio and video data. In this case, it is best to use an MPEG based third-party conversion application like MPEG Streamclip, VisualHub, FFmpegX, iSquint, or other application compatible with your particular operating system.

I need easy audio and video converting and editing software?

I need easy audio and video converting and editing software that wont cost $400.

I highly recommend you try Video Monkey. It's free, though donations are certainly accepted, and does an excellent job of converting .mov to .wmv. Choose Best (2 Pass) for Encoding Speed and depending upon the size of your original file, uncheck 320 pixels wide to create a larger converted image. I set Quality to "Go Nuts".
Another good commercial program is Video Converter Ultimate for Mac. It works as video converter and editor. The version for 2 Pass conversion is approximately $69. , which is considerably less than the $400+ that Adobe Premiere is asking for its editor. I'd still prefer a freebie though, but there's little choice...

Best practice video conversion from download

I am looking for best practice for video conversions.
I am downloading adobe recordings via this method:
http://server.adobeconnect.com/xyz/output/filename.zip?download=zip
From here, I have been converting the FLVs using either freemake video converter or FLV converter. I have tried converting into AVI (XVID), MOV, WMV, etc. (I need the file to be under 600 MB for an hour of recording, therefore it is going to need some type of compression).
My goal is to import the video into Sony Vegas Pro 10 for further editting. I have found that whatever method I use, the video and audio does not sync properly about 50% of the time. The video time is longer than the audio time usually. Or that there are other various errors, such as the video just freezing halfway through the video.
I have been using connect for a few years now, but with each update I find (connect 8, 9, etc), that the problems are getting worse. At this point I am just wasting time trying to convert into various formats using various codecs just trying to luck upon one where the video is at least without error.
What methods are others using to convert the FLV to a workable editable format?

Can't the FLV files be changed into many different formats through Apple's
Compressor or Adobe Media Encoder? These formats can then be opened in
standard video editing software for editing.

Yes, I use this as a last resort, as the quality of capture this was is
signifcatnly lower. As well as it is a much more time consuming process. I
sometimes have over 50 parts of 1 hour video. To use camtasia, you need
first to record it, then it must be saved in a camtasia format, and then
lastly rendered into avi or wmv. Therefore, it is does take awhile.
Really, I feel there shouldnt be so many errors in the conversion process,
but I am finding the FLV recordings themselves have problems. This last
file I am looking at, even the recording playback on adobe connect, has
serious issues with audio and video sync. A problem that is all too common

Adobe Captivate 7 Project How to make Rollover cations, audio, and video work in HTML format?

Adobe Captivate 7 Project How to make Rollover cations, audio, and video work in HTML format?

Honestly, I don't even know why this is an option. The conversion to Flash is completely unusable.
I have exported some things to Flash, and since I program in Flash all the time I was able to manipulate to work to some degree. Most text captions are built with multiple elements and completely fall apart.
Sorry, I can't be of more help.
