Hi there!
I used to have a Sony 3D camrecorder and so I got thousands of 3D MTS files.
I can watch them on my 3D videoprojector but each video takes a long time to load so it's not a very nice way to enjoy them, especially when each shot is a separate file and most of them last around ten to twenty seconds.
So basically, I just want to merge these 3D files so I can get videos that will last longer and will be more comfortable to watch. I don't even care about "editing" them actually.
I don't "need" to convert them to another format since the MTS are working in 3D on my projector when I play them on it from my harddrive. But if I absolutely have to convert them, then I would need to find a way to keep the HD quality (lossless).
Can anybody help me?
Thanks a lot!

Unless your 3D format is MVC you could try
Code:ffmpeg -i "concat:file1.m2ts|file2.m2ts|file3.m2ts" -c copy output.m2ts
-
It's the ffmpeg commandline which stitches a number of input files (denoted here as file1.mts, file2.mts etc.) together and makes one big file denoted here as output.mts from these.
You will need to have ffmpeg.exe installed on your computer though.
You could also make a text file which includes the files which you want to join, like
Code:file 'file1.mts' file 'file2.mts' file 'file3.mts'
Then run this commandline:
Code:ffmpeg.exe -y -safe 0 -f concat -i mylist.txt -c copy output.mts
But usually handycams are shipped with basic (proprietary) editing software with a user-friendly GUI which should support your needs.
Alternativley, you could also check out FFMpeg Batch Converter or ShotCut which support the concatenation (i.e. joining) of video files.Last edited by Sharc; 11th Oct 2021 at 09:53.

Thanks, Sharc!
I downloaded FFMpeg Batch Converter and I did a test. The concatenation worked but the new file is not in 3D anymore.
It is still useful for 2D videos that I have or for sharing them with friends who don't have 3D players but it still didn't solve my problem. :/
So I guess it may be MVC? How can I know that for sure and what can I do then?
Thanks again for your help! -
If it is MVC you would find an SSIF folder with .ssif files
Upload a short sample of your 3D .mts source so we can take a look. Possibly the 3D concatenation is not straightforward, depending on the 3D packing.
Most 3D TVs can however play SBS formats. So the 1st step would be to convert (i.e. re-encode) all the files to SBS and then concatenate..... -
I didn't find any SSIF folder so shouldn't be MVC then.
I just uploaded a video, it's attached to this reply.
If I convert the files to SBS, would it be lossless?
Thanks again! -
OK. Both views are in the same .mts.

When I split the file and re-concatenate, the straight concatenation seems not to work properly
Probably because the 2 streams in the .mts are "base" and "dependent" (as with MVC).
Can you play this file in 3D?Last edited by Sharc; 11th Oct 2021 at 17:17.

Try this. It's your sample concatenated (2x).
Does it play correctly in 3D with your gear? -
What worked best for the concatenation of your 3D video is converting it to SBS before joining, because stereoscopic SBS are standard AVC files.
You can try player compatibility with the attached sample (it is your sample repeated 1x).Last edited by Sharc; 12th Oct 2021 at 04:25.

Hi Sharc, thanks a lot for helping me.
Unfortunately, none of them works.
The first one (combi.mts) doesn't play at all, it says the file is damaged when I plug my harddrive to my Blu-ray player and try to play it from there.
The second one (2xSBS_.mts) plays in 2D, with the side-by-side images, and also there is no sound.
Looks like I'm asking for something more complicated that I expected. -
The 3D player may have a setting which forces 3D plaback of SBS sources. Or perhaps I could have set a flag which controls the player. Not sure though.
I didn't include the audio for this test, by intention.
Looks like I'm asking for something more complicated that I expected.
You may check with the videocam supplier for adequate tools which are normally shipped with the camera, as the joinig of clips is a very common task.
Maybe somone with more knowledge will chime in. -
Last attempt
Try this .mkv file (again no sound).
It plays nicely 3D on my TV and triggers the 3D view automatically -
Sorry for my late reply!
Yes, it did work!
So... how did you do that? There are several steps, right?
Thank you! -
Good to hear that it worked for you.
The steps for each .mts clip are:
1. Demux the .mts clip
Tool: tsMuxeR
2. Decode the MVC video
Tool: DGMVCSource or FRIM
3. Arrange the 2 views as SBS
Tool: AviSynth+
4. Encode to AVC
Tool: x264 Encoder (you may use any of its GUIs)
5. Remux the video from step 4 and the audio from step 1 to .mkv SBS format
Tool: mkvtoolnix
and finally: Join the .mkv files from step 5.
Tool: any like mkvtoolnix, ffmpeg, etc.
(Steps 2. and 3.are combined in an AviSynth script)Last edited by Sharc; 15th Oct 2021 at 03:01. Reason: typos
