Join MP4 - two windows in VLC

[cele_82]

Hi,
I've used successfully,in the past, used Yamb to replace an audio track in my photocamera's mp4 videos.

These videos are h.264/mpeg-4 avc 720p 30fps.


My problem now, is to join two pieces of different mp4 videos without reenconding.


If I do this with Yamb, it doesn't work (VLC open two windows and play the 2 videos at same time)

I've tried with AviDEmux with no success.



My goal is to append a video that I've created(same specs of the camera) to one of my photocamera.
I don't care about the audio, I need just the videos (if is possible to have both I will not complain )



Can someone please try and help me?


Here are the videos:

1. The one I created http://www.mediafire.com/?jfqjm4onlyi
2. A small clip from my camera. http://www.mediafire.com/?zxw4qcmmdgf


Try to join the 1 to the 2 and (also I have tried to join 2 to the 2) but the results were always the same: two windows in VLC.



Ideas?

Have you tried join with yamb 1.6? not the latest beta version.

Have you tried join with yamb 1.6? not the latest beta version.

Tried now, it always popup with a windows saying mp4box has crashed.... etc....

[cele_82]

I've tried from command line as well (with Mp4Box)

and with version 0.4.6 mp4box crashes...., with 0.4.5 it creates the joined file but the second video is not visible.

You could try AVI Demux for joining.

The only thing that looks odd is that the first file has a framerate of 30 fps, but an original framerate of 60 fps (does this mean interlaced 60i footage ?) and the second clip says only 30 fps (which may imply progressive).

I've already tried, but please download the files and try with your PC... maybe is mine that have something wrong.

[guns1inger]

AVI Demux produced an unplayable file. I also tried TSMuxer, which happily loaded the second file, but would not read the streams in the first.

Going over the specs again I notice that the first file has been encoded to Baseline level 3.1 profile with no CABAC, while the file from the camera is Main profile 4.0 with CABAC. This may also be part of the issue. When I re-encoded the first file to better match the specs of the second, I could at least get tsmuxer and yamb to open the files without complaint, and attempt to process them.

Neither resulted in a successful join, but it seems to indicate that the problem lies in the encoding settings of the first file not being close enough to the settings of the camera file to allow for a simple join.

Ok thanks the first file is the one that I can recreate without problems, I have Sony Vegas 9 I will try to create different versions... the only thing that I don't know how to change is the "Main Profile" because I've use Sony Mp4 codec and I didn't find this option.


So:

- Do you have any success converting the first file, (to closer specs of the second?)


Please help me....

[guns1inger]

I used Xvid4PSP, and set the profile to 4.0 to match the camera output, and used an encoding setting with CABAC turned on. That got me a closer match in mediainfo that you have, but I still could not get the files to join. After conversion I could at least get TSMuxer to recognise both files. It would not recognise your original first file.

Ok so you're saying.... I've to give up?

[guns1inger]

No, I am saying you haven't found the settings yet to allow you to do a simple join without re-encoding the camera footage. I am saying that I was able to get closer than you did, so you need to look more at how you encode your footage if you want to do this type of join.

You can chose to give up, or you can choose to re-encode both clips to the same settings then join.
