Sony AVCHD m2ts rendered files question mark.

I am using VMS 10.0 for a few months now and I have the following (may be naive) question:

What can be the use of rendered m2ts (16Mb/s) files using the Sony AVCHD format template ?
considering that as soon as these files overpass some minutes:
- the videos become "choppy"
- with huge synchro video/audio issues
- and they cannot be even re-imported in VMS 10

Does someone have an idea of why Sony is proposing this format?

Merci

First, make sure that your project's properties match your video format. You can open Properties under the Project menu or by clicking on the Properties button on the Preview panel.

If you match your project settings to your video, you shouldn't have any choppiness or out of sync problems.

What kind of camcorder is your video coming from and how are you getting this video onto your computer?

Then, for output, go to the Project menu and select Render As. On the Render As screen, set your Save As Type to Sony AVC. (I think you're asking how to output AVCHD video, right?)

I was surprised to read this post, so I tried rendering an mts file as m2ts, using Sony AVC. I had no trouble importing the m2ts into VMS.

Thanks for the answers.

I just did a test again, insuring the option "match project property" was "on" and the rendered file become choppy and de-synchronized after roughly a 1 minute duration.

My configuration is as followed:

- Camcorder Sony HDR-CX550VE Pal (64GB-SSD)

- Laptop Sony VAIO VPCF13C5E, Intel(R) Core(TM) I7 Q740@1.73GHz, Ram: 8G, HDD 500G, NVIDIA GeForce GT 425M, BluRay burner
- Windows 7 64bits Home Premium
- PMB native Vaio
- Vegas Movie Studio HD Platinium 10.0 Build 179

- Computer tower, Intel(R) Core(TM) I7 CPU 950 @ 3.07GHz, Ram: 6G, SSD 60G, HDD WD Velociraptor 600G, HDD WD 2Teras, NVIDIA GeForce GTX560Ti
- Windows 7 64bits Familial Premium
- PMB
- Vegas Movie Studio HD Platinium 10.0 Build 179

- Camcorder video format: HD FX (AVC HD 24Mb/s(FX))

- Process:
- media (AVCHD m2ts 24Mb/s) acquisition using PMB in order to keep the GPS infos and to ensure the date/time in the name of the clip is the one when you start filming (if you acquire directly thru VMS10, you loose the GPS info file and the name of the clip shows the date/time when you stop filming)
- editing on VMS (very few transitions and other sophisticated editing stuffs)
- rendering with the "by default" Sony AVCHD format 1920x1080-50i 5.1 Surround as described hereunder:
Audio : 448 Kbits/s; 48 000 Hz; 24 Bit; 5.1; AC3
Vidéo : 25 ips; 1920 x 1080 Champ supérieur en premier; YUV; 16 Mbits/s
Forme du pixel : 1,000
- rendered file: m2ts becoming not-watchable after 1 or a few minutes

I made around 10 rendered files this way, varying from a few minutes to 35 minutes, the firsts of them being under FH format (17Mb/s) (never mixing format) and they all have the same problem.
None of them, by the way, could be re-processed in VMS: either VMS crashes when I transfer the file in the timeline or if I am successful to do it (no idea about why, but it happened) then it crashes when I move on or read the timeline.
I have being doing these operations on my two computers 64bits W7 and I even tried on my old XP 32bits one with identical results.

I was assuming:
Sony Camcorder + Sony Vaio + Sony PMB + Sony VMS 10.0 Platinium + Sony Codec&Format = No issue...I missed a variable...may be it's myself?

I apologise for my English...Merci for your comments

Post Scriptum:
Steve, I just realised that the book I just received from "Amazon", intitled "The Muvipix.com Guide to Vegas Movie Studio HD Platinium 10" is yours.
1) congratulation for your "education" process. Really excellent and rare!
2) be carefull when you refer to keyboard keys...they may acte differently with others non-qwerty keyboards...
3) may be a Pal_25 images/s environment differs from a NTSC_30ips one in term of VMS functionalties.
