Hi Mark,

Thank you for writing back.

Development is a aware of the issue and they hope to correct it quickly. I do not have an estimated date as to when this will be fixed. Most likely this will be fixed in an update to the current version. Since you are using the trial version, it will most likely run out before the next update is released. I can suggest that you download the trial on a different machine when the next update is released so you can test this.
You can stay notified of any updates by going to options, preferences, general, and checking the box that says “Use Net notify to say informed of Sony product updates.”

If you still have a follow-up question on this particular incident, please feel free to update it. If you have a completely different question, please create a new incident.

I rendered out to 1440×1080-60i as you suggested. There is no problem in rendering to that format. As you mention “There appears to be a related issue when rendering directly to the same format as the source footage.” This is exactly what I have been trying to communicate. You have now made two separate recommendations for me to render my 1920×1080-60i clips to less than desirable formats. The question remains what to do in order render to the same format? I am glad that Sony has taken the step to acknowledge that there is a problem. When may I expect a solution to the problem? Thank you for you continued assistance.

Hi Mark,

Thank you for writing back.

I spoke with development today on this and here is what they recommended. If you are rendering to the exact same format and template as the source footage, they suggested testing a render of Sony AVC with a template of 1440×1080-60i. There appears to be a related issue when rendering directly to the same format as the source footage. Please try the 1440×1080-60i render and see if it turns out any different.

I have passed your information along to development. As soon as I hear back from them I will let you know. I will set this incident to the development status so that it does not become solved.

As you can see it is a known issue. It is suprising how long it took for them to acknowledge the problem. I had been in contact with Tech Support for approximately two weeks before the latest response.

I also have found that there is a time/length discrepancy between the native file and the rendered file. Also the bitrate will change considerably in the rendered file. This data I have viewed simply thru Windows in highlighting the files(I have Windows 7).

I have found, as have others, that passing the clip thru tsMuxeR fixes the issue and syncs the audio/video properly. This seems to fix the time/length discrepancy and the bitrate issue. I have not had the chance to closely scrutinize the video, however, to make sure that there are no artifacts.

Did you ever figure out how to fix the rendering problem? I am so frustrated as rendering freezes up and stalls out…please help if you have solution thanks

[Dan Goug]

I’m having the exact same problem everyone else is having. 🙁 Rendered my first 1920×1080 .m2ts last night in vegas pro 9.0 and while watching my wonderful compilation the video locked and the audio kept going. My video is 16 minutes long now and will be over an hour long once done. I hope Sony gets this fixed soon. :-\

[Chad Muska]

Has anyone gotten an update on this current issue?

[Nathan Smith]

I haven’t tried anything in a while. I have a home video of my son’s first birthday that is now over a year old (he just turned 2!), but I haven’t edited it because of this issue.

I don’t get how they’re letting this problem continue. A large majority of new HD consumer cams shoot 1080i avchd. What do they think people are rendering at?

[Norman Willis]

Hi Nathan.

I’d just like to confirm that your camera is 1080i and not 1080p.

I never heard of AVCHD in 1080i.

If it is 1080i, I would recommend starting a new thread, so as to get the forum moderators’ eyes on it, because they will know about 100 times more useful information than I would.

I hope that helps.

Norman, I’ve said it is 1080i from the very beginning. As far as I know, there are zero 1080p AVCHD consumer cams that shoot at 60fps. Not a one. The canons (and maybe some others) can shoot at 1080p/30, but definitely not 60.

Here’s a PC mag review that says 1080i: https://www.pcmag.com/article2/0,2817,2339933,00.asp

They are advertised as “1920×1080 FULL HD,” but they are all 1080i/60, or 1080p/30.

I just came across this thread yesterday and it has helped me immensely. I too suffered from the rendering crashes of Vegas 8 which were fortunately fixed in Vegas 9. However, the AVCHD files I was making would stutter and audio desync during playback on PS3. I tried the suggestion of using tsMuxer and it worked!

I’ve spent the last few hours using tsMuxer on all my AVCHD files (the final edited versions). I do have Vegas 9d and there is no mention of this as a known bug, so I hope they take care of it for 9e. Seems like it would be an easy fix.

I started with SR12, now have an XR500, and getting CX550 next week. Finally seeing AVCHD at full frame rate on HDTV is a good feeling.

Hi, i also see that theres no fps set, but how do i change that?
regards.

[Arnar Kon]

I have now upgraded to Vegas Pro 9.0e and the problem still persists. I have also tried the tsMuxeR and while it fixes the picture/sound sync issue and the jerking is minimised I still have dropped frames every now and then. What I do is I add the rendered video into the muxer and click ‘Start Muxing’. Should I try any of the options? I did try to set the ‘Change fps’ to 25 (Which is the framerate of the original) but with same results. Anyone have this same problem?
