Jumpy Video After 2 minutes or so

I am editing AVCHD video out of a Panasonic HDC-TM700P camcorder. The recording is recorded at the top resolution of the camcorder which is 1080/60p. When removed from the camcorder, it is converted to AVCHD by the Software (HDwriter 2.1) included when the camcorder was purchased. All this comes into VMS HD Platium 10 with no problem. Editing is no problem and rendering is no problem. I am rendering as Type = Sony AVC, Template AVCHD 1920x1080-60i 5.1 surround.

In playing back the rendered video using WM player, all looks fine until about the 2 to 2 1/2 minute mark. At that spot, the video starts to get jumpy.

Is this related to problems with the program or cound it be my system. I using a Lenovo T-410 with an Intel Core i5 CPU @2.53GHz, 4G of Ram, 64 bit Operating System with Windows 7 Professional.

Could this be a system issue? That as it renders it gets to a certain point where it is running out of memory or the CPU is getting bogged down?

Just thought I would ask because it does not make sense. It is not the video because I have broken it down into 3 1 minute sections (the video is 3 minutes long) and those 3 section work just fine.

I was hoping that I could take those 3 section and put them back in line and not have to render them to put them back together but the system started to render them all over again.

Any thoughts?

Thx

I have also encountered this problem, but only when rendering using the Sony AVC encoder. If you use the Main Concept encoder it does not occur (but rendering times are longer). I am a new user of Sony Vegas and have put this problem to them, but have as yet not received a reply.
Hope this helps.

Barcol,

What Mainconcepts Codic do you use and does it generate and AVCHD file?

I had a similar problem using Movie Studio 9 Platinum with AVCHD video from my Sony camcorder rendered with Sony AVC to AVCHD 1080/60i .m2ts files. Not only did the video get jumpy after about 2 minutes, it started to lose A/V sync, getting worse the further into the video you played. I have not had this problem with v10 HD Platinum, but the fix that worked for v9 (suggested in this forum, I think) was to run the rendered video through tsMuxer (freeware). That fixed it every time. tsMuxer is fast (doesn't re-render).

You might not have the same problem, but It might be worth trying tsMuxer.

I used the main concept AVC/AAC, supplied by Sony and on the rendering menu. I f you select the default template (1920X1080) you can then customise the settings bit rate etc ( I use 20M max, 14M average and 256k for audio).
It generates an mp4 AVCHD file which I have burnt to DVD and played on a sony blue ray player.
Hope this helps-it seems to work fine for me, although rendering times for a 10 minute fairly low complex edit takes about 100 minutes!
