Muxing m4v and aac files
Hi,
Afer the export of an HDV project with PremiereCS3 as an H268 movie, I have an Error Message at the end and instead of a mp4 file, I have a m4v video file, an aac audio file and a file with a .idx extension. Is there a method to mux the video with the audio in order to obtain a single .mp4 file? Thank you for your assistance. -

I believe there is an option for this in the H.264 output settings – the last tab maybe? Check them all, I’ve seen it somewhere.

David,
You are right the Export Settings dialogue box as a Multiplexer tab with 3 options: mp4, 3GPP and none.
After extensive testing I suspect that the lack of automatic multiplexing by Premiere CS3 at the end of the export process might be due to the fact that Itunes is opened (sometimes with my ITouch connected to the computer) when I am doing the export. Subject to confirmation after further tests which I will undertake; in particular with a 30 minutes sequence. Many thanks. -
Wow!
I was referring to CS4 ad Adobe Media Encoder – but the interface is nearly identical.
Hope it all works out. -
After experimentation of the Export/Adobe Media/ H268 mode of a 6 minutes HDV project, it turns out that with that a large project I have again the lack of muxing at the end. Instead of a single .mp4 audio+video file, I have a .m4v video and a .aac audio file which I dont know how I can mix them in a single mp4 file.

H268?
To be honest, I never used .mp4s much in CS3. I was still using QTs for most final delivery.
In CS4, because QT support isn’t as good, I started using H.264 instead and in CS4 it works better than anything else. Now that’s all I use unless I run into a client who’s computer is so old (or their media player – usually QT – is so outdated) that it won’t play .mp4 videos at all. (I play them in Nero’s media player or QT – though interestingly, QT does not recognize pixel aspect ratios in mp4 clips – so I have to make sure i export FINAL clips in square pixels – no matter how they were shot. Weird that Window Media Player doesn’t recognize .mp4s at all – though I guess that’s deliberate, since their WMV Video codecs from 9 on are based on the mpeg4 standard, but is proprietary, and being Microsoft and wanting to dominate the world, they’re trying to make everyone use WMVs…which I have stopped using almost completely as well.) -
David,
Thank you for the above information. Are you using HDV or AVCHD rushs? I wonder wether it is possible to produce H264 movies from HDV rushs. -
Technically, you can export from any format to any format.
But yes, I have exported H.264 from HDV and from AVCHD (and everything else.) -
Hi,
I am very happy with the results I got exporting with the H.264 feature but for an unknown reason I am now unable to export a timeline lasting more than 3 minutes (as mentionned earlier I am getting separate video and audio files); consequently I am now using the Mpeg2 mode. I have pretty good results using a CBR mode at 10 MegaBytes per second average bitrate but scenes with motion like panoramic are slightly lacking fluidity. Would you have an advice about the best settings to use with the AdobeMedia encoder dealing with HDV footages? I display my movies on a Full HD 52″ TV. Are the HDTV settings available in Adobe CS3 presets more specifically devoted to the TV display? Thank you for your assistance. -
Are you playing back the H.264 video using quicktime? I have noticed that the quicktime player (and I have the latest version of QT) do not playback H.264 very well. I notice lag in the QT player for 10MB/sec video but not in 3MB/s clips. I have no problem playing back the 10MB/s video using Nero’s media player (the latest version too.)

I am playing H.264 movies on a Multimedia hard disk player but I dont know on which platform this player is based, it works very well. As of the media players installed on my computer: Quicktime 7.6 (472), Windows media player 11, VLC player 0.9 8a: none of them plays my H.264 movies. May be because I do not have an HD monitor. The real question that I have is for which reason my Premiere CS3 cannot any more export a timeline higher than 3 minutes as an mp4 and produces only a m4v video and a .aac audio files that I dont know how I can mix them into a single file? Thank you.
