Video stutter on play back after AVC rendering

[Steve Rhoden]

Can you do a system restore, back to when things were ok?

Thanks Steve.

My last successful project was created on 15th July. Unfortunately I am unable to find a restore point before 4th August. I restored the system to this date (4th August)and tried a render. The result is bad, again same Video stutter. Can you tell me how to restore the system to a date before July 15th?

Thanks,
Ananda

Hi Steve,

While browsing the forum I saw a posting regarding almost identical problem as mine although using Vegas Studio Platinum. The problem was again with Windows7, 64 bit system. The problem was reportedly solved by passing the rendered video through TsMuxer GUI. I did exactly the same and my problem of Video stuttering was amazingly gone. I want to understand how this happened and has anyone else encountered the same problem with Vegas pro10e as myself and has this been addressed and solved by Sony? Moreover since my problem was encountered suddenly (the same system was working previously), I am all the more perplexed.

Below is the copy of the posting regarding using TsMuxer for solving Video stutter problem.

Renders HD fine for 1st 3 minutes, then stutters (Vegas Movie Studio HD Platinum 10)

Hi there,

I am trying to render a 20 minute full HD clip on Sony Vegas Movie Studio HD Platinum 10. The rendering itself completes without a hickup. On playback, the 1st 3 minutes and about 20 seconds is perfect – the clip then starts to stutter and the sound sync seems to seperate from the video. I cannot drag the time elapsed cursor to a later footage section, or the video freezes from where I dragged the cursor – sound continues fine. I can always drag the cursor back to the 1st 3 minutes footage and that plays perfectly.

I have tried rendering various sections of the video – the same result – whatever the footage is after about 3 minutes and a few seconds, there the trouble begins. It therefore seems as if the footage itself is not the problem. (footage at the place in the video where the problems start renders fine if that part of the video is in the 1st 3 minutes). So the problerm happens after about 3 minutes pkayback time which is after about 15 minutes rendering time on my system.

No screensaver or sleep or anything like that interferes.

Details:
Windows 7 64 bit system
6GB of RAM
i7 920 processor

Footage in AVCHD format (1080) and rendering to 1920x1080i 29.97fps (m2ts format). I have also made another project 3 minutes 48 seconds in total without any problems – using the exact same settings.

Any ideas will be appreciated.

I had the same problem with version 9 platinum, and still have it with version 10 HD Platinum. It seems to occur with AVCHD clips when rendered by Sony AVC to .m2ts files. It may be limited to Windows 7 64 bit systems, but I am not sure about that. (The few other reports I have seem from people with this problem were all using Windows 7 64 bit.)

Earlier this year I found a solution that someone posted here (or maybe it was in another forum). It works every time for me. I routinely apply the solution for every final Sony AVC render from VMS. I don’t remember who found the solution, but I am grateful to that person. Here is what works for me:

Run the file rendered by VMS through a program named tsmuxerGUI. It runs fast (doesn’t re-render) and somehow corrects the problem. In the tsmuxerGUI interface, add your VMS-rendered file with the “Add” button, keep all default settings except select .m2ts as the output type in the little buttons near the bottom, designate the output location where you want the file to go, and click “Start Muxing”. The resulting file should be free of stuttering and A/V sync problems.

Of course, it is possible that your problem is being caused by something else, but I think it would be worth trying this solution.
tsmuxer is freeware available here:

https://www.smlabs.net/tsMuxer/tsMuxeR_1.10.6.zip

As I recall, it doesn’t install itself in Windows or change any registry settings, it just runs from the .exe and the other files that are included in the .zip.
