QT 7.5.5 AVI to MP4?

Hello
I have converted a AVI to MP4 via QT and there's no sound at all after conversion and why is this?
Do I just go back and use VH as usual or is there a way around this
Thanks

What was the audio codec (and video for that matter) in the source file? DO you have Perian installed? If not a good idea.

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.

Ffmpeg avi to mp4 issues

I'm trying to convert a video (Choke) from avi to mp4 format so that I can put it on my old 5G ipod video.
ffmpeg -i /home/wes/Videos/Choke/Choke.avi -s qvga /homa/wes/Videos/Choke/Choke.mp4
returns
[mpeg4 @ 0x83580a0]timebase not supported by mpeg 4 standard
Error while opening codec for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
I thought that should work, but I've been wrong before so I look around the wiki and the aur. I tried furiusconverter from the AUR and got similar errors. Avidemux doesn't work either. I'm getting really frustrated since from what I understand this should be working flawlessly. So I turn to the wiki and I find some code:
ffmpeg -vcodec xvid -b 300 -qmin 3 -qmax 5 -bufsize 4096 \
-g 300 -acodec aac -ab 96 -i INPUT -s 320x240 \
-aspect 4:3 output.mp4
I got some errors pertaining to the bit rate that went away when I changed "-b 300" to "-b 300k" and "-ab 96" to "-ab 96k". There were also problems with "-vcodec" and how "xvid" was not recognized so I just got rid of "-vcodec xvid" but then I got the first error I posted.
The wiki also had this to offer: http://thomer.com/howtos/mp4ize
but after making it into "Converter.sh" and chmodding it (777) and running it I got another error. This error may have something to do with my not having Ruby installed but I think I do so it shouldn't be a problem.
Does anyone know if I'm doing something wrong, how I can fix it, or any bit of wisdom?
On the fringe,
--Wes
EDIT:
So I installed Ruby (stupid of me not to check) and tried the code in the link above again. It seems like it's working and we'll see in a while if it did or not, but I'm still really curious why ffmpeg isn't working for me. Can some one please tell me what I'm doing wrong with ffmpeg so that I don't have to keep using this homebrewed script?

man ffmpeg wrote:-s size
Set frame size. The format is wxh (ffserver default = 160x128, ffmpeg default = same as
source). The following abbreviations are recognized:
qvga
320x240
i'd try it as simply ffmpeg -i file.avi file.mp4 and see if it works. maybe that size is just not supported by mp4

Importing avi and mp4 files into iPhoto

I just finished importing my PC photo library into iPhoto and I ran into a snag.
iPhoto does not import video files in *.avi or *mp4 format.
On my old PC photo library, I have video clips taken into mostly avi format with older digital cameras, and which are stored in the same photo directories by date. When I realized that I could not sync avi files to my iOS devices, I used a conversion program to convert the the avi files to mp4 format, and was able to sync these to my iOS devices.
Now apparently iPhoto does not recognize these mp4 files. I would like to have my video clips in iPhoto so that I can sync them as needed to my iOS devices through iTunes and also sometimes use them for video editing in iMovie. Within iMovie, I see where there is a link to the iPhoto video library... so somehow I have to get these into a format recognized by iPhoto.
Can anyone recommend a method that will accomplish this? I assume I will have to convert the avi/mp4 files to some other format. Is there a utility that will extract out the video files from my hundreds of photo directories and let me convert them to the accepted format by iPhoto, preferably keeping the time/date stamp intact?

Check over on MacUpdate for file converters.

Export issue with avi and mp4

Stitching together AVI or MP4 files

Does anyone know of any programs that will allow you to stitch together several avi or mp4 video files?
Meaning allowing one to play right after the other.
Thanks.

Can you drag all of the file to iMovie and make a sequence out of it? And save as QT after that?
Try this one:
http://www.apple.com/downloads/macosx/video/visualhub.html
And you can burn to DVD after it done encoding those files.
I found it worth every penny I spend on it.
Good Luck.

AVI or MP4 full of jitter after export

Hi,
I've been working on iMovie 11 v9.0.4 build for a couple of days now and it seems completely impossible to export to a stable final avi or mp4. The imported files are fine in HD and look perfect when viewed withing the project in iMovie. But whatever format I try to build or filetime it jitters like crazy, and I'm starting to go crazy!!!
Any ideas are welcomed
cheers,

The song is at 44.1khz and some additional audio at the beginning and end is at 48khz. I exported the audio out through Final Cut separately at 48khz and then reimported that audio over the sequence and while it worked on the timeline, again upon export it drifted out of sync.
Is there an easier way I can resample the audio in FCP? Or do I have to import it into Soundtrack? The sequence settings are at 48khz.
Thanks.

Avi vs mp4

Hi,
I experience very big file size difference rendering to avi or mp4.
I always believed avi files would be smaller than mp4 my adobe premiere 10 gives other result. Am I doing something wrong here? And what are the pros and cons to avi or mp4?
Thanks for replying,
Koen

In addition to what Steve and John have offered, the two main determinants of AV file size are:
Duration
Bit-Rate
The CODEC used has a little effect, but mostly they allow for the data to be compressed, yet still leave acceptable quality. The lower the Bit-Rate, the lower the quality, but also the smaller the file.
Where CODEC's differ is by the allowable compression of the data, coupled with the acceptable quality. Some are better at the compression, than are others. The H.264 CODEC, usually found in MP4 wrappers, is very good at giving one acceptable quality, but still compressing with lower Bit-Rates.
Many of the CODEC's, commonly found in the AVI wrapper, are not quite so good, so to get the higher quality (read higher Bit-Rate), the files' sizes WILL be larger. One exception is the DivX CODEC, which does yield good quality, and lower Bit-Rates, and can compress the data very well. However, this CODEC is designed for delivery of streaming media, and is NOT meant to be edited later.
Editability is a big plus for the H.264 CODEC, and that is why it is used in so many HD formats, like AVCHD (a sub-set of H.264), today.
However, and with all of that said, there are major variations in H.264, so there are few universal specs. With DV-AVI, a particular CODEC, in the AVI wrapper, things are much simpler - the MicroSoft DV CODEC is standard, and uses low-compression, and higher Bit-Rates, to keep quality high, but at the sacrifice of file size.
There ARE a few CODEC's, usually wrapped as an AVI, like Lagarith Lossless and UT Lossless, that maintain lossless qualtiy, while still doing a good job at compression, but no where near as good, as most versions of H.264 - however, and just as their names imply, they are "visually" lossless - great quality, though at higher Bit-Rates and with larger file sizes, than most versions of H.264. For intermediate files, that will be edited later, I rely heavily on both of those lossless CODEC's. With the proper CODEC's installed, they both edit very, very well too. Also, one can do many generations of Encoding, without a noticeable loss in quality, where that is not true with H.264, where the compression will show an accumulation of a loss in quality, because of the high compression.
Hope that helps,
Hunt

Viewing mov, avi, and mp4 files in photoshop 12

How can I view mov, mp4, and avi files in Photoshop 12?

thanks for your reply Tom. the video is from cameras, video cameras, vhs tapes, and mini dvds. everything looks much worse after import into fcpx; i haven't imported hd files. The specs. are, everything gets blurry and color pales. i just tried importing four more files (and optimized), all mov, (no avi or mp4), and there is no change in quality. I'm comparing the video in fcpx to the same video before it was imported. i've compared it side by side to the files being played in quicktime, real player, idvd, and el gato eye tv (third party video capture software). everything is crisp and color is vibrant before going into fcpx.

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.

Avi to mp4 to play on 5G ipod

i got lots of AVI films on my HD
now i want to turn them into MP4 to use them on my video ipod
how can i do that
I'm an apple user so can't use any windows apps
i tried pspware but somehow a few things got wrong there so...
maybe i need a ser nr to use that properly or a psp player witch I both don't have
what can i use to easily transfer avi to MP4 to put in a good resolution on my ipod?
I used ponder trial to get them from mp4 to my ipod, but podner does not like AVI
Or do I need a ser nr to make that really work to?

i found my own skeletons
if you want to have avi played on your ipod use isquint
if your mp4 made with ipod won't fit to your ipod, throw him on isquint as well
if you even want to have subtitles on your avi use no frills dvd2ipod, you need to dl ffmpegx on the way to use it but once you fixed that the sky is the limit
it even eats video_ts as in handbrake, but it guaranties ipod cooperation
you could also use QT ipod settings but it takes ages to render the film, my ffmpegx seems to be pretty fast
good luck
it works fine for me

Free conversion software from avi to mp4

Hi has any body know of a good "free" avi to mp4 convertor that works?

Hey there,
I would use Handbrake or Videora (both of which are free). I have had great luck with each.

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/
