Mp4 converted video file is missing audio codec

I have several avi. files on my computer which were converted to mp4. using videora software. A few of these converted mp4. files then had no audio when I tried to play them on my Ipod. I am confused as to how to add the audio codec back into the video files. Do I have to install this to avi. then convert to mp4., or is there some audio codec which will apply directly to mp4. so they do not have to be reconverted? What is the procedure at this point? Thanks for your help in advance.

First thing to do is find out if Videora supports whatever audio codec the AVI uses.
If it supposedly does, write it off as one of the many bugs with videora and get a different transcoder that supports the audio codec.
Outside of having good knowledge of video production and the right tools-there is no easy way to do what you want.

Converting video files to mp4 for nano 3rd gen

I'm trying to find a quick, easy, hassle free way of converting video files such as mpg and avi to mp4 so that i can watch them on my new ipod nano.
Anyone got any suggestions and ideas?

Ricktoronto and others,
Thanks for all the advice! I do have MPEG Streamclip and I'd thought about it, but have not really used it all that much. I didn't spend a whole lot of time looking at it but just did now and see that you convert to Quicktime and in there, you select Apple MPEG-4 and do all your adjustments. Now my version says that it will convert to H264. Does that function not work right?
The bottom line though is I ended up returning the Video iPod. The biggest drawback is the fact that it does not have Firewire as all I have are Macs with USB 1.1. I could upgrade my Blue & White G3 and put a USB 2.0 card in it but that machine would be REAL slow to convert video. And my iMac of course, can't be upgraded. If I had USB 2.0 or the iPod had Firewire, I would have kept it....
Still, I'll mess with the conversion programs and see what works best. I'll figure out how to do everything and then once I'm up to speed, maybe consider getting one.

Convert Video files in iTunes but no Audio after converting

Hy, do somebody know what is the matter if i want convert Video files in iTunes (8.01) but after converting the files don't have any audio but i can see the movie perfect in iTunes and on ATV ????

Your likely using muxed video such as mpeg1/mpeg2, which is capable of being played back in QT (with the QT mpeg2 playback component in the case of mpeg2 source video) but not able to be converted.
I could well guess which software you should use to undertake your conversions but it would be better if you could provide details of our source video so that we can suggest an appropriate workflow based on that information.
You can use the Inspector window in QT to see this information.

I bought an iTunes Royalty free song to play behind a presentation. What I have seem to have is video file not an audio file. Am I missing a step?I want to download iTunes purchases as a .wavfile of other audio file. Any help would be appreciated.

I understand the confusion. Those tracks are royalty free to the owner of the tracks, yes. The terms of use of the iTunes Store still state, though, that all purchases are for your own personal use and cannot be used commercially:
USAGE RULES
1. You shall be authorized to use iTunes Products only for personal, noncommercial use.
They're probably fine for presentations in a class or to a group at your company, but you probably could not post the presentation or a video using these tracks on a public site. I'm no lawyer, though, to legally define what would and would not constitute "noncommercial". It's probably best to just buy your tracks directly from one of these sites of royalty-free music. Then the use license should be completely clear.
Regards.

Wow that was a chore. Apple! Let us drag copy and paste our info tabs information so we don’t have to type all this stuff when we are having trouble. **another problem and suggestion** right there.
Ok, back to the problem of the forum.
From what I can see from http://www.apple.com/ipodclassic/specs.html this file falls in line of everything required in order to be able to play on my iPod. It plays in iTunes fine but will NOT sync with my iPod. I get an annoying message that states, “Some of the Songs and videos in your iTunes library, including “BlaBlaBlaiPondFixYourJunkBlaBlaBla”, were not copied to the iPod “My iPod” because they cannot be played on this iPod.” Why oh why can iTunes play this video file but my iPod cant. Especially when the specs on Apple’s website say it can.
So that was bugging me for a LONG time until I found my “Create iPod or iPhone version” option in the “Advanced” heading. Thank goodness this made my files playable on my iPod. Extremely LONG wait though. I know that other programs convert it in ½ the time. But times not to important as long as it gets done, (would be very convenient if it was faster though **Problem and suggestion**)
Ok, now that I have used the “Create iPod or iPhone version” option it has slowly but surly converted my video. Ok, here is my main problem, the new file which is the result of the conversions information is as follows:
Kind: MPEG-4 video file
Size: 35.4 MB
Bit Rate: 125 kbps
Date Modified: 8/18/2009 2:15 PM
Play Count: 1
Last played: 8/21/2009 1:28 PM

Video Codec: H.264
C:\File\WhyIsThisNewFileInMyMusicFolder\TheMovieFileInQuestion.m4v
So basically it has made my file bigger *not a bonus in my book* greatly increased my Bit Rate *another interesting feature*, and I think the biggest change it has changed it from an .mp4 to an m4v.
Why does it need to be an .m4v I could have sworn some of my videos were or are in mp4 which shouldn’t matter anyway because I was under the impression that iPods could play mp4 files. So that’s my biggest complaint and question. Why can my 80GB classic iPod not play my MP4 files and why am I forced to convert them??
This conversion also creates 2 files in iTunes when I am done which is annoying because I have to go into my files info and look to see what file is the mp3 in order to remove it. Very annoying I can open my iPod options and see the files and some are faded (the ones it can not play) why can’t I remove them from that area.Suggestion Apple please make files that cannot be played on my iPod stand out some how for easier cleaning Suggestion. Thank you.
Speaking of cleaning iPods, when I moved my entire library to an external drive I was faced with a terrible problem. “This file could not be found, would you like to locate file”, I was faced with this annoying message at least 600 times. Now I am glad that iTunes has a little “!” mark to show dead links so that you do some minor cleaning, Good Job iTunes No compliant there. However iTunes has no way of selecting all the broken files for major cleaning (like in my case). Going through and deleting over 600 files 1 by 1 is extremely time consuming and annoying. **Suggestion Apple please add more cleaning features for organizing iTunes**.
Ok, speaking of organization now, another problem that appeared when converting my video files was that it put my new videos into the location where I have all my songs (my external hard drive) why can’t it put the new files in the locations of the original file? I have my computer highly organized and my original files were in that drive in that folder for a reason. If I could open my original file and skip the conversion, my iTunes would go to that specific folder to access the file which is fine. But now these new conversion files are elsewhere taking up space and disorganizing my computer. True I can go into the new location and move the files to where I want them (original location) but I don’t think I should have to hunt them down, copy, move, delete ect etc for all these files over and over. Very annoying, time consuming and should be unnecessary. **Suggestion Make file creation and location more customizable, and user friendly, your customers will love you for it**.
Well since I have gotten into Apples iTunes and iPod problems that I have had to face I might as well bring up one or two more problems and suggestions. About a month after purchasing my iPod a sibling bought one as well. His however is way more convenient then mine. I suppose he has a 5th gen. so here is my question: why does he have a search option and I don’t!!!! Why does he get more features every so often and I don’t?! Why can’t Apple write some software for us classic guys which got the iPods going! It’s very annoying when I have to spend more time looking for the song then I spend actually listening to it, when he can pull his up in like 3-6 seconds? I highly doubt the hardware between our iPods is that dissimilar and even if they are why cant software be written for us. **Suggestion treat all your customers good not just the newer ones, and make some more features for the classics like me and my iPod.” We will be grateful for it I promise.
Ok, I am almost done. Let me just recap my questions, I know my post is kind of lengthy.
#1. Why can’t my iPod play MP3 video files? And why do I have to convert to almost all the same settings except changing it from an mp4 to an m4v. according to Apples own site I should be able to play .m4v .mp4 and .mov files!! Note: remember iTunes plays them fine but my iPod will not.
#2. Would be much more convenient to be able to copy the information from the windows in iTunes so that problems and trouble shooting would be much easier. A little check on off options in iTunes advanced settings would be terrific.
#3. Why is the conversion so slow? Please speed it, you have the power. Convenience is the thing that sells products.
#4. Files that cannot be played on the current iPod need to be easier recognized for simpler cleaning.
#5. Also make an easier way to select all dead link files for faster cleaning, deleting, etc. This one is important.
#6. Make a user friendly way to change where my files are going to end up once I convert them for iPod more options and better customizable settings are need.
#7. One of the most important is ADD A SEARCH OPTION. I and we classics will LOVE Apple for it.
For you readers, I apologize for the long post, and any grammatical errors you might find throughout it. These are problems that I have faced with these programs and hardware and I wanted to make sure they got acknowledged and hopefully addressed. Any information about why I cannot play MP4 Video files on my iPod would be the best. If anything in my post gets answered that’s the one I want most. Will save me a lot of hassle.
Thank you all and I look forward to your suggestions and comments. All are welcome and appreciated.
Sincerely,
Bond, James

Was playing with iTunes and thought of another suggestion! Let us play files in iTunes from an iPod! A friend or sibling should be able to plug his iPod into my computer open iTunes and play any of the files there. Many times I have wanted to show a movie clip or video to a friend, and I have the dock so I can do it on my T.V. but play it on their computer in their iTunes forget it. That would be a very nice feature as well so we can watch our movies at maximum size or listen to music on a better sound system, just another suggestion that would be nice. Thanks

Converting video files for the N97

Can anyone recommend a good piece of software for converting video files into mp4 for the N97?
I have tried Nero, and various other freeware and shareware packages, and I am able to produce a file which will play on my PC, but nothing which will play on the N97. In some cases the phone cannot see the file at all, other times it's there through file manager, but only plays the audio, no video.
This is getting frustrating!
Thanks
Andrew

Give Format Factory a try http://www.pcfreetime.com/ converts virtually all video types including DVD.

How to convert video files so they render in FCP?

I'm having trouble converting video files and using them in FCP. My problem is I have to keep rendering a clip every time I modify it in FCP. I know how to fix this issue with audio by exporting a file to the correct sample rate, but with video I can't find the correct option. I've tried converting my video to MPEG-4 and Quicktime movie but nothing works.

Convert it to a nle friendly format like DV, Pro Res, etc. Mpeg4 is not nle friendly.
Import the video.
Make sure the sequence settings are the same as the video clip--i.e. if you converted the video to DV NTSC 29.97, the sequence setting should match that.
If your sequence settings match your video, you won't have to render unless you add an effect or transition, etc.

What is the best software for converting video files to .ogg format?

Turns out the answer to that question changes if you ask it more than 4 times, so ask it again....
The answer depends on the type of video files you want to convert. If they are DRM protected commercial videos, no help can be given here. Google.

Does version 12 support producing video clip with AMR audio codec?

From some documents i used as reference to proceude some videos for my phone Premiere Elements 8 can produce video clips with AMR audio codec. I bought today the Premiere elements 12 but I can not find a way to set AMR audio codec for my video clip. Only AAC audio codec seems available. Is it possible to add AMR codec to 12 version?

Neurona17
Adobe typically supports only current version, and, if you purchased from it, is strict on "within 30 days of purchase": for money back on that current version purchase. I do not believe such a thing as a "change the license for other earlier release such as 8 or 9" exists at Adobe. But, you could ask. If you wish to purchase one of those earlier versions that supports AMR export, you might still find some online.
Is the before import conversion of AMR to WAV a viable alternative?
You wrote
Unfortunately so far I have not been able to generate any useful video clip for my system with this 12 version.
Is this in regard to the AMR requirement or to any video without the AMR audio?
Online I have seen that there is a download for the AMR audio codec. Does your system now show that you have such a codec installed on your computer. If not, I am not sure if download of this codec would place it in the Premiere Elements Publish+Share export settings choices, similar to import of some .avi video codecs. (Sometimes 3rd party codecs can create problem, so proceed with caution if you pursue that AMR audio codec idea.
Please update us on your progress when you get a chance.
Thanks.
