I know with Visual Hub you can stitch two videos together. I haven’t tried it, but it has that option

seems to be re-encoding. and if i do pass through ffmpeg flags it makes two seperate mp4s and a stitched audio mp4. (???)

any other thoughts...

this will be interesting itchie. i'd like to find out if you get it to work. since the GOP pattern will start and stop in different places for the two files, i'd like to know how a program is able to join them without re-encoding, since the GOP pattern would be broken in a simple join. at the very least, the program that stitches them would have to generate dummy frames to keep the pattern in tact.

found this in a forum.
"SimpleMovieX
You can join two mp4 movies by copy and paste and then save it to mp4 without reencoding.
It's very very fast."

just tried it and it worked great (trial version) it only took a couple seconds. it did seem to flash a frame or two in-between the two mp4s. but since i leave a couple seconds before and after my edits its all good. i will try with other files and get back to you...

also, in that same thread someone said that ffmpeg does this. maybe you can try it in your scripts.

weird. serato isn't reconizing the second video/audio in the mp4. both mp4's were created in handbrake with the same settings. the two videos play as one mp4 fine in quick time.

a-swift, do you think serato is not reconizing the second video because of what you mentioned? or could it be something else? it would be rad if this worked...

yes itchie. That is what I think

Damn you... J/k

so it looks like it's all about nesting the two project files (edits) in a new project and render out from there. not as quick, but better quality & stability than what i was trying to do. as always thanks for the input...

i was originally going to tell you to use FCP but i wanted to see what you came up with.

use the media manager to minimize re-rendering.

I think this will also work with mp4 files, but i dunno, if you test please post results.

use ffmpeg
