Join two parts of a movie

[GabrielWolff]

I have two parts of a film, named Across.CD02.avi and Across.CD01.avi.

Both are around 700 MB.

I would like to join them to one big file.

When I opened a terminal and typed in:

cat Across.CD01.avi Across.CD02.avi > Across.avi

I got one big file of around 1.4 GB, but when I opened it, it played only the content of the file Across.CD01.avi, and the time shown by VCL was that of Across.CD01.avi as well.

How could I make it work?

off the top of my head (ie, you may want to check) do

mencoder -forceidx -aoc copy -ovc copy -o outputfilename.avi input1.avi input2.avi

the forceidx thing rebuilds the idx index, which can help with sync issues that can arise. the aoc and ovc copies are basically 'copy the audio and video and dont reencode either'

Uh...

i have used this to join 4 .avi's so that i can ffmpeg them into .mpg and author a DVD with it... however, it will go through the first video, then i get the error:

All video files must have identical fps, resolution, and codec for -ovc copy.

...? what do i do here? the code i originally used was:

avimerge -c -o PhysII_Lec05-08.avi -i PhysII_Lec05.avi PhysII_Lec06.avi PhysII_Lec07.avi PhysII_Lec08.avi

but the audio/video was WAY off, so then i:

 mencoder -forceidx -oac copy -ovc copy -o PhysII_Lec05-08.avi PhysII_Lec05.avi PhysII_Lec06.avi PhysII_Lec07.avi PhysII_Lec08.avi

this time the sync was great, but as stated above it only went through the first video and then stopped...

any suggestions???

I made an executable file called "vidmerge" in my ~/.gnome2/nautilus-scripts folder, and filled it with this:

#!/bin/bash
mencoder -forceidx -oac copy -ovc copy -o $NAUTILUS_SCRIPT_CURRENT_URI/merged.avi $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS
exit

Now all I have to do is select the files to be merged in nautilus, right-click, and select "vidmerge" from the scripts menu. Merge in progress!

Todo:
- instead of "merged", use the string the source files have in common, minus things like "cd" " cd" "_cd" ".cd" "-cd" "part" " part" etc. Else, if they have nothing in common, use "merged"
- Also, check if it exists, first. Ask for overwrite.
- ignore non-avi files (if mencoder isn't already doing that)

That would make the ultimate script. Any suggestions on how to do that, particularly the file name manipulation, would be welcome

netgrazer, feel free to adapt it for use in nautilus.

also to open a enhacement request to ship it
it's fully integrated with the gnome enviroment... only if notify-send was default in ubuntu....

see screenshot.


it also report on completion, errors from mencoder, and warnings about file overwrite and such.
