Joining AVCHD Files

burchis13 wrote on 7/7/2014, 5:33 PM
I have a Sony HDR-CX760 camcorder and Sony Vegas Pro 9.0.

I want to join all the individual files that gets created from a filming session into one AVCHD file. I have done this several ways with different 'Save as type" options but the rendering takes more than double the timeline. What format is native to the AVCHD file?

I wouldn't think that any re-rendering would be needed if I am just joining/appending like files together and outputting them into the same format.

Help me understand if I am thinking wrong.

You need to download the free "TSMuxer" program. It joins them together and eliminates the gap between them.

I have read about this program and many say that audio does not stay synced with video.

You don't have your computer specs posted so we can't say if this is normal rendering time for your machine or not.

Sony has a program called PlayMemories Home (I hate the title!), which is the successor to PMB (Picture Motion Browser). It is primarily a database program but does transfers and other things as well.

It provides a slowish but (what I like) a brainless method of concatenating all the .MTS files into .m2ts for each scene. Futhermore (also what I like), it names the .m2ts files according to shooting time and date. The copy has to be from the original memory card or camera.

You can also use the old DOS copy command:

copy /b file1.mts+file2.mts+file3.mts fullfile.m2ts

but it is more tedious

The latest versions of Vegas always re-render AVCHD, but if you have a licence for version 9 you can use 9C which will smart render AVCHD if it is in a good mood. However, the AVCHD files have been arbitrarily split and if you just drag them to the timeline, you are liable to get a glitch at each join.

You can also try the free mtsmerger utility which is 37.6 kB :)

Vegas' Device Explorer will import them and join them together, no rendering needed. I don't remember if version 9 has it....

I was about to post the same. I have all version from 13 down to 10 on my PC but not 9. 10 does have the device explorer, not sure about 9.

That's true on some avchd cams but not the newer Sony avchd cams.

The newer cams have been designed to drag off the cam even when the cam has split an extra long clip. The cam will automatically rejoin the split clips as you drag them off. I believe the cx760 is even included in that. I have the PJ790 and it automatically completes the split clips.

Vegas 9 avchd smart rendering was never perfected (which is probably why it was removed). Teh clips would smart render until it hit a part which was changed (ie; a fade) then it would drop out of smart render mode to render the fade, but not kick back into smart render mode afterwards.

Completed clips stay in sync just fine. It's the split clips that have the problems. There is also a glitch in the newest version of TSmuxer so download an old version and you will be fine.

The newer cams automatically do this.
