Sony Acknowledges AVCHD Rendering Defect

[Bokman Chan]

I came acroos another thread that seems to solve the problem:
Run the renderered AVCHD file through tsMuxeR and output as M2Ts. The file now plays smoothly with audio in sync (over 20 minutes long.

Thanks a lot, TsMuxer fixed the issue!

What is tsmuxer and where do you get it?

I applied the cff explorer fix and ran into the exact same problem, audio out of sync after 2 minutes.

Before the fix, it would crash when I tried to render to 1920×1080 .m2ts file. After the fix, it render quickly and looks like everything is working like it should. I render a 9 minutes file and found the audio out of sync after 2 minutes. No problem rendering it to wmv in 720p format.

System spec:
Win 7 home premium 64 bit
Athlon X4 945 (3.0 GHz)
8 GB memory
1 TB Seagate 7200 rpm.

Anybody find a way around it?

I will now try and render to other format. I’ll try it at 1440×1080.

Source file comes from Canon Vixia HF S 10 shot at 1920 x 1080 at 17Mb/sec.

Steve,
I thought the audio was out of sync too but it turns out to be WMP 11. Try reimporting the rendered file back in Vegas and see if it is out of sync. I rendered it to .m2ts file at 1920 x 1080i and thought it was out of sync when I use WMP to play it. I then put it on a memory stick and the PS3 played it fine with out any audio sync problem. I stumbled on a thread about the audio sync problem and it turned out to be a WMP problem.

So now after the CFF fix, it rendered 1920 x 1080 in in the Sony (.mp4, .m2ts, .avc) template just fine.

Finally, a program that works as it should.

I got tired of the resource hog Premiere Elements 8 and the constant crashing so I downloaded the trial version of Vegas PE 9 from Sony to try.

I have exactly the same problem. With Vegas Pro 8.0 I was not able to even render to AVCHD format as any video beyond 15mts used to crash. I downloaded the trial version of Pro 9.0 and with this was successfully able to render a 45mts footage in AVCHD. However, once I played this file on my Popcorn hour A110 media player the video started freezing every other frame while audio worked perfectly. I tried using TxMuxer as suggested, but the output file from TXMuxer still had the same problem. However, I tried the following based on a suggestion given in this forum. I used Sony Picture motion browser to download the clips from my camera. Choose the clips I want and then select “create AVCHD disc” from menu, insert a DVD blank and then under Disc creation option choose” Create a disc that plays the Video smoothly and seemelessly”. Create the DVD. While that is finished you will have a M2TS file in the stream directly of the DVD. This file plays very smoothly on the Popcorn. This proves that popcorn is able to handle AVCHD persay and hence there is something wrong with the AVCHD format rendered by Pro. The above method has the following limitation. Firstly I cannot use it if the total length of all the clippings I need is more than 4.7Gb or 8.4 Gb if I use double sided DVD blank. Secondly I lose all the editing features of Vega Pro. Till today I have not been able to successfully generate a AVCHD file out of Vegas Pro that I have been able to play on my HD TV using Popcorn hour. I am desperately waiting for any suggestion. I am currently rendering to a modified template using main concept mpg and choosing 1080i resolution and stereo audio. This guzzles a lot of disc space, too much rendering time as vegas rerenders and lose the 5.1 audio.

I found the same render issue in Vegas 9.0e, when project is rendered to avchd 1080i. When rendered movie play in pc or HD player, it become choppy after 2or 3 min. I’am very upset about this. I have to choose HDV as render method now.

[Igor Gofman]

I have the same issue. After rendering with my Vegas 9 pro (ver. 9.0e) it is impossible to play with any player. I have a media center Ultio MVIX that virtually plays any format. It plays M2TS file but it’s very choppy.
So, I render into M2T format and after that I convert the file into M2TS with 4UM2TS converter.
If you found the way how to fix it, let me know.
Sincerely,

I’ve had the same issue with Vegas Movie Studio HD and Vegas Pro 10 when rendering 1080i AVCHD. I came across this thread when googling the problem and the solution suggested earlier in the thread has worked for me – I ran the rendered file through tsMuxer ( https://www.smlabs.net/tsmuxer_en.html ) outputting it as an m2ts file.

Good luck with it.
