Problem while encoding AVCHD video with Sony Vegas

[RiDDleR2]

Hello,
I'd encountered a problem while I was trying to encode a 4:23 minutes long AVCHD clip with my Sony Vegas program.
It goes like this: I imported that clip, dragged it into the timeline, cropped about 20 seconds of it, added a transition in the middle (the cropped part), rendered as Sony AVC - AVCHD 1920x1080 PAL template and saved.
The size of the original clip is a 530 MB, and the size of the new encoded one is 480 MB which, so far, makes sense.
The problem is when I try to play the NEW clip. The first couple of minutes runs smoothly, quite the same as in the original clip. So far so good, but after that (and actually, it's even a few seconds after the cropping-transition) - the clip begins to go glitchy and jumpy, and you just can't watch it normally.

Does anyone have an idea why this problem occures? And even more important - how can I get it to be fixed?

Thanks a lot!
Jonathan

Everyone have the same problem
Sony AVC codec is broken
there are 2 options
1 - use a free tool called Tsmuxer open the final video click in the bottom m2ts muxing
start muxing
the new video will play smooth
but don't do that if you use dvd archtect because it will crash.


2 - use another codec such as mainconcept it is awesome!
but you must change the codec settings to mix the audio and video

Thanks!
I really used tsMuxer eventually. It worked just great! Didn't even seem to re-render at all.
Anyway, I couldn't add any transitions to the video.
Sony Vegas won't allow it (for the reasons I've mentioned), Adobe Premiere seems to re-render too much, and I don't know any other good programs which would allow to re-render only in the transitioned part.

Anyway, thanks again!

What version of Vegas are you using? I do not have this problem with Vegas Pro 10. There is a program that has a "smart render" feature to only render certain parts. It is called TMPGENC 4.0 XPRESS and their mpeg editor. It only re-renders what it needs to and leaves the rest of the video alone.

i heard that vegas pro don't have this problem.

Cyberlink Power Director uses a SVRT function (Smart Video Render Technology) that render only the affect areas of the video.
I have power director 8 and it is fast.

You may have heard wrong. I have Vegas Pro 9.0e (32-bit and 64-bit) and the Sony AVC codec often has problems. But not always. Today Sony AVC codec will not render at all in Vegas 32-bit, but works sort of in 64-bit. Works, but audio in rendered playback is way too fast. (OS is Win 7, 64-bit.)

My colleague uses Vegas 9.0e on a different machine, and the Sony AVC codec seems to work okay for him. Our machines have same hardware specs and same OS: Win 7, 64-bit.

Maybe I have some crap on my machine that he does not have, and it's some kind of software conflict. Oh yeah, I use a Wacom digitizer pad and he does not. Who knows?

You're right
all version sucks with AVCHD 1920x1080 sony avc codec.
version 10 pro either.

Vegas still need TsMuxer.
