Copy MOV to MP4

[ericjdaniels]

I am new to the forum and to Avidemux.

I want to change MOV files into MP4 files with as little loss of quality as possible.

When I open my file I get a H.264 warning, I click "yes", then choose "copy" for Video and Audio and choose MP4 as format and I get this error:

"Invalid audio stream detected. The audio stream may be invalid for this container."

I click yes to continue and it crashes.

Any ideas?

Thanks so much!

what type of audio in the mov container?

use mediainfo

not all types of audio are compatible with mp4 container

[ericjdaniels]

Video stream - AVC
Audio stream - PCM

[poisondeathray]

PCM is usually not compatible in MP4, but some variants of LPCM are

You might be able to re-wrap it with ffmpeg (command line tool)

Why do you want MP4 container ?

I want to be able to plug it into my Sony Bravia TV using a USB and play the video.

The TV says it supports AVCHD, AVC, and MPEG4.

I tried selecting MPEG-4 ASP (mpeg4) for video and finally got the video, but can't get the audio.

[poisondeathray]

If you select that for MPEG4-ASP video, you are re-encoding the video (losing quality)

Where are these files from? A camera ?

Thanks so much for the help. Yeah, I figured I'd just share a little and not get into the whole big thing.

From the Canon SX230 camera. Trying to get them from MOV to a useful format. Trying to figure out how to make them easily posted to Youtube, Facebook for family to see. Trying to figure out how I can view them on my TV in an easy way and was hoping I'd just be able to copy onto a USB drive and watch. HA! I should have known.

So here I am.

Thanks again for the help. I really do appreciate it.

For things like youtube, facebook, - you should be able to upload the files as is . They will be re-encoded by the sites, resulting in a lower quality version for streaming in a browser

I would try tsmuxer, and put it into a .m2ts stream

Most TV's have very limited support for playback (they are very "finicky" and will reject many formats - you can do a quick search, this topic comes up all the time here), and note some TV's have problems with USB input

[ericjdaniels]

Ok...so I opened my file in tsMuxeR and it said "Some tracks not recognized. This tracks was ignored. File name..."

This was the output while muxing:

SmartLabs tsMuxeR. Version 1.10.6 http://www.smlabs.net Decoding H264 stream (track 1): Profile: Baseline@5.0 Resolution: 1920:1080p Frame rate: not found
H.264 stream does not contain fps field. Muxing fps=23.976
H264 bitstream changed: insert nal unit delimiters
H264 bitstream changed: insert pict timing and buffering period SEI units
H264 bitstream changed: insert SPS/PPS units


Then it finishes.


Here are the problems: I can see video on my PC, but no audio.



When I plug it into my USB and into my TV, I see no video, and hear no audio.


The plot thickens.

It's going to be a quite of fiddling around until you figure out what works

I can tell you right now AVC L5.0 - even baseline profile - is usually not compatible with most hardware chips, especially the cheap ones found in HDTV's. They will reject it immediately

I suspect you are going to have to convert both audio & video to make it headache free and playable on your TV . Unfortuantely this means quality loss, and time spent re-encoding the files
