Converting AVI to MP4

I have a number of older AVI files that I'm trying to convert over to MP4 so that I can not only play them on my computer, but on my HD TV as well. They are older, like I said and not in HD, but having the ability to show off my videos on the big screen
I pulled them into Premier (using the school computer after class) and queued them to convert to MP4 using H264 and 720p. Now the original files were NOT HD, and I know that the quality won't get any better during the process, but I figured that this would have less quality loss during the conversion.
The files converted in about 15 min each, and I took them home to check. Seems to play fine from my flash drive right from the TV. Cool! Trouble is, when I watched them on my computer screen all the way through to check the quality, I noticed problems. During some scenes, mostly during pans, the images smeared (the best description I can think of). It's not huge, but since it's not there on the original, I can't imagine what would cause it, unless it's the decode/encode process.
I'm going to test it with MPEG2 / HDTV 720P 24 High Quality next, but I wanted to get a feel on what would be the best option for this type of conversion. I don't really know if my TV will play the MPEG file types since I've lost the book for it. :/
As I said, they are older files and certainly not HD so I know that the quality won't improve, and I know that some degredation will occur, but I'd like to keep it to a minimum.
Thanks in advance for any advice you can offer.

According to Premiere, the original was not ntsc (512x384 (1.0) 23.97fps, Progressive) The original files were pulled from the camcorder (an older type that used big clunky video tapes, old for it's time even in 2003) by a friend since my computer at the time was not able to do so for some reason. He also encoded them the way they are now.
As to DVD, I actually did that a few years after getting the originals encoded, but a recent viewing of them showed that they degraded and some of them no longer play. The disks act like they are scratched but the disks themselves are in perfect condition. I've thought about getting a blu-ray burner and disks and putting them all on there, but that will have to wait until after the holidays at the earliest...
Anyway, I'll give the SD Youtube preset a try tonight and let you know how that works out. I'm not terribly interested in changing the aspect to widescreen. I can deal with the black borders. Once I've got the formatting figured out, I've got some more, even older videos to convert. These came from some very old 8mm film of my fathers.
Thanks again for the suggestions.

Converting AVI to MP4 for FREE

Does anyone have a FREE program that can convert AVI (as well as other formats) to MP4, for my iPod Touch?

Hi,
look here http://www.macupdate.com/info.php/id/22923/perian
But if your signature is correct, it is of no use for you on a Windows PC, as it is Mac-only.
As for Windows (and/or Mac OSX as well) have a look at MPEG Streamclip http://www.squared5.com/svideo/mpeg-streamclip-win.html

Converting .avi to .mp4: No audio

I am trying to convert an avi to mp4 so I can play it on my ipod. I only plan on doing this 1 file so it makes no sense for me to purchase Quicktime Pro or VisualHub, so my options are iSquint and MPEG Streamclip.
After trying within iSquint, the conversion works but the quality of the mp4 file is almost unwatchable.
I then tried it in MPEG Streamclip but this is where my problem begins. No matter what I do I can't get audio on any output file. The avi file plays normally in Quicktime and VLC, but I've noticed that in the player in Streamclip there is no audio.
Even exporting to other output files gives no relief either.
I've looked at http://discussions.apple.com/thread.jspa?threadID=1616285&tstart=0 that addresses a similar problem but don't see anything to help my specific situation.
Some possible useful info:
~/Library/Quicktime contains -
AppleIntermediateCodec.component
AppleMPEG2Codec.component
DivXDecoder.component
DivXEncoder.component
Flip4Mac WMV Advanced.component
Flip4Mac WMV Export.component
Flip4Mac WMV Import.component
(note the first 3 file have a white lego block as their icon, the second 3 have a white page as their icon.)
When playing the file in Quicktime the Quicktime Movie Inspector gives this info:
NMP1.avi
DivX
Format: DivX 6.0, 608 x 246, Unknown MPEG Layer 3, Stereo, 44.100 kHz
FPS: 23.98
Data Rate: 708.03 kbits/s
Normal Size: 608 x 246 pixels
Current Size: 608 x 246 (Actual)
While the file is in the MPEG Streamclip player the Stream Info displays
Bit Rate: 0.75 Mbps
Video Tracks:
DivX 5.0, 608 × 246, 23.976 fps, 634 kbps
Audio Tracks:
MPEG Layer-3 Audio stereo, 44.1 kHz, 112 kbps
Stream Files:
NMP1.avi (790.21 MB)
Does anyone know what is causing this problem and/ or know how to fix it?
Running 10.5.4 on Macbook 2.16GHz C2D 2GB
Quicktime Player v7.5
MPEG Streamclip v1.9.1
VLC v0.8.6i
thanks, b.
(ps I didn't know which section to put this thread under so went with Quicktime as a safe bet.)

Thanks for replying guys.
I tried what you suggested Ricktoronto on a small test file and it worked!
You've made my day, been trying for a couple of days to get this to work.
Is it ok to delete those DivX files from my mac now? I have the DivX player still installed, that won't crash if I delete those files, will it?
Many thanks, much appreciated.

Programs for converting avi to mp4/h.264

As the title says. I'm looking for a really good program for this, i want really good video quality, and it doesn't matter if the program is for free or if u need to buy it. I'm a windows user.

As I understand it, AVI is a somewhat lower quality to begin with. That said, you can use Quicktime Pro to convert to your specified format. Quicktime Player for Windows is free; the QT Pro upgrade will be required to output to mp4/h.264.
You can get Quicktime via http://www.apple.com/quicktime/

Converted .avi to .mp4 for Premiere Pro CS6 but receive a header error.. help?

When I imported .avi video file into Premiere Pro CS6, only the audio played. I used VLC to convert the .avi file to .mp4 through a batch file. Now when I try to open the .mp4 file into Premiere Pro CS6, I receive an error "File cannot be opened because of a header error".
I've tried converting the .avi file to .mov and .wav but they receive the same header error.
I've also tried opening in Audition and resaving it as .wav pc but it still won't import to Premiere.

First, depending on what is inside the AVI file, it should/might be "naturally" supported by Premiere

Converting avi to mp4 for ipod??

how can i convert my avi clips from my digital camara to mp4 for my ipod

Drag the files into the open iTunes window and then convert them. Some AVI files cannot be played in iTunes and you may lose the sound upon conversion; if either happens, use Perian and MPEG Streamclip respectively.

Lose audio when converting avi to mp4 on quicktime

I've read the discussions on this but can't find a fix so far.
When I try and convert an avi file to mp4 using either quicktime or MPEG Streamclip, I lose the audio. I don't believe I need to download the quicktime mpeg-2 component for mac osx given I have 10.9.1, but perhaps I do (there is debate on this and I'm confused)?
I tried downloading MPEG Streamclip 1.9.3b8 but it seems to want that component to attach itself. Should I therefore buy it - will it work?
Alternatively, should I buy quicktime 7 pro? I really don't want to.
Can somebody help...please?

So I made a successful and audio distortion free ACC/AAC mpeg4 (.MP4) video from Sony Vegas for the Ziio. You are given a choice of audio (I chose 92kbps). The problem is solved. No more distortions. And all this time I was doing twice the work by importing the MPEG- files into Any Video Recorder and converting to .MP4. That was the distortion result. Hope this helps if you're doing the same kind of work by combining video and audio. Otherwise, it's up to you...

Cannot convert avi to mp4 to my Ipod Touch

Im running on Windows XP. And I use PSP Video 9 to convert my avfi files to mp4. Now I get them converted and then I import them to itunes. I sync it to ipod but it tells me Ipod could not put it on ipod or something like that. I've tried it with 3 different movies and it all does the same. This never happened before I bought the 2.0 upgrade. Can anyone help?

Try right clicking the item and select the "convert selection for ipod". Something like that. iTunes will convert the video to a format for iPods. This happened to me and I used the iTunes video encoding system to encode the videos to mp4. Try it and please report back results.

How do I convert a photo booth file to an AVI or MP4?

How do I convert a photo booth file to an AVI or MP4?
I tried exporting the file from Quick Time to my desktop, but the file extension reads as .m4v - is that compatible with other pc?

The M4V format is a video file format developed by Apple and is very close to the MP4 format. The differences are the optional Apple's DRM copyright protection, and the treatment of AC3 (Dolby Digital) audio which is not standardized for the MP4 container.
If your M4V video is not unprotected M4V files and without AC3 audio. It may be recognized and played by other video players by changing the file extension from ".m4v" to "mp4".
So you can try to change the file extension and check if it works. If it doesn't work, try Leawo video converter(for windows or mac) and convert m4v to mp4 format.

Bad performance of video convertion from .avi to .mp4

I use QT Pro v7.0.3 to convert avi video to mp4. The mp4 quality is bad. I am unsure if mp4 movie is bad in quality or QT Pro is bad in convertion. As iPod selects to support mp4 video, the quality should be of an acceptable one, otherwise, it just damages iPod reputation. It is my first time to watch mp4 video but the impression is not to bother at all - worse than vCD. Is there any one using mp4 video? Any comments!
Thanks,
Ray

I set my QT avi to mp4 conversion to 2500 kbits/sec, current image size, current frame rate, and it's still worse than the original avi. FAR worse.
I've given up on encoding my avi's to play from my iPod. It just stinks, so I'm not sure what to tell ya... just that you are not alone in your observation. They look OK for play on the iPod, but playing from the iPod to anything else, like say a TV, it's not worth it. It seems to be better to just play the avi via some other means on the TV, because the conversion is seriously sub par.

I'm trying to view my movies through itunes and apple TV but only a few appear in itunes when i add to library, they include .avi and mp4 files. Whys have only a few copied and rest wont add to my library, can someone help? Do I need to convert them?

Can't convert flv to mp4 when I publish to html5

Hi
I have a project that incorpporates FLV files which where imported succesfully. When I publish to HTML5, the flv files fail to convert to Mp4. Ironically, if I publish the entire project to mp4 it works?
Has anyone got any ideas.
Cheers

Ps I am using Captivate 7

REsolved
I have been using a third-party program to generate FLV files. Although captivate 7 accept these files & publishes these files in certain formats (including mp4), the Adobe media encoder is unable to convert these files into mp4 format if you want to publish them as html5. In order to resolve this, I had to bring files into captivate as either AVI or MP4 files. The Adobe media encoder then converts them to an acceptable FLV for captivate. If I then publish to HTML 5, the media encoder successfully does the conversion.
As a quick test I tried to directly convert the third-party generated FLV files using adobe media converter into F4v files and then import them into captivate, however the Adobe media encoder would not recognise the flv format.
Therefore, if you come up with a similar problem, I strongly recommend that you bring in your video files as avi or mp4 and let the Adobe media encoder do its work.
Cheers
