Divx audio out of sync when viewed in VS10

Doublem2 · Post by **Doublem2** » Fri Jan 12, 2007 2:07 pm

I have a Divx show that I downloaded from the internet, which I want to burn to DVD so I can send it to Mom. (Yes, I recorded it but was too lazy to get video capture hardware and capture it myself.) It's an .avi file that uses divx for the video and mp3 for the audio, 624x352 on the one I'm testing with. They run about 350MB for 45-50 minutes. I tried another file and the same thing happened.

When I play back the video in VideoStudio 10, if I first click "project" next to the play button, the audio gets more and more out of sync as it progresses (2-3 seconds after an hour). However, if I click "clip" next to play, the video and audio are perfectly sync'd. When I create a video file or burn a DVD, the result ends up with the audio out of sync like the "project" playback. It doesn't matter if I: make a disc image first; have one or multiple clips in the timeline; view the first or last clip; or use MS AVI vs mpeg2 edit mode.

I installed the patch, and the video playback now stutters for several seconds when I begin playback in project mode. Installing the latest divx codec didn't help. I've seen plenty of mention of audio sync problems with divx; has anyone noticed this difference between the two playback modes? Has anyone found a better workaround than converting the divx to a different format? And what format is suggested for this (preferably one smaller than mpeg2 at 4000+kbps)?

Thanks

Hi Doublem2

You said:- has anyone noticed this difference between the two playback modes?

Yep---video studio does struggle when playing some video files in project playback mode.
VS has to read the project, then play the project, all to be done in real time.

If you play in clip mode then this is just like playing using any other media player, read straight from the hard drive. Easy to play in real time, or should be.

What is strange is the problem when converting the Divx, If its in sync¡¦ for the clip playback, then it should be in sync¡¦ after converting, After all the converting is not done in real time, it takes as long as it takes.

So struggling to play in project playback should have no bearing on the final render, I think.

DivX !

Try using SUPER (FREE!!!) to convert the file to MPEG-2 before importing it into Video Studio. You can search some of the DivX web sites to find special DivX software. Or, you can try SVCD 2 DVD (~ $40 USD).

DivX and Xvid cause lots of trouble. If you search the forum for DivX, you get lots of "hits". The more compressed the format, the more potential trouble when you try to edit or convert it....

As you may know, a lot of the more recent DVD stand-alone players will play DivX discs -- the rating to do so usually appears as a decal on the player's case along with DVD-/+R, VCD, Kodak, MP3 etc. (I have an LG which does so, for instance, but there are heaps more on the market at quite cheap prices these days...) If your mother has one of these, then the answer is simple: just burn your DivX video straight to a CD, in effect as an archive file using any burning program you want. Put it in the DivX rated player, and it should recognise the file and play it back on the TV no problems...

But if you want to burn it to a video DVD (or your mother only has a standard DVD player or you're not sure), then you have no choice. It HAS to be converted to DVD-compatible mpeg-2. No ifs, no buts...

I personally have no difficulty with DivX, but I can't give you any secrets as to how I do it. It was just that way on my computer from the first time: put the divX file in the timeline, go to Share > Create Video File > DVD, and it happily produced a DVD-compatible mpeg-2 with video and audio in sync. Then I would simply close the project, and with an empty timeline, I would go to Share > Create Disc, and the burning module would open. I would insert my new mpeg-2, create a menu and burn. It has worked each time.

But I acknowledge what has been said above about DivX (and XVid and related mpeg-4 codecs) causing a lot of people a lot of problems. So if the standard method I outlined in the preceding paragraph does not work, then I too would recommend trying out SUPER...

I thought I would say in reference to DivX, that I'm finding that I get better results converting MPEG2 DVD files to DivX using DivX's converter, then I do using VS to create a DivX video file from a DV. I've been toying with some short clips, where I create a DVD MPEG-2 using VS10+, then use DivX MPEG2 to DivX converter. I will then use VS's Share>Create Video File, and use the DivX codec on the same DV file used to produce the DVD MPEG-2.

I think I tend to agree with you Ron, on the DV-to-DivX route.

Mind you, I have also achieved some excellent results on that route using VS10+. But the DivX codec settings I used had to be among the highest (and slowest) possible. And the final file was a little large (180 MB for a 7 minute DV clip) for most people. But the quality was truly excellent.

Lesser settings in the DivX codec within VS gave far inferior results -- and believe me, I tried them all!

Thanks for the replies guys!

That tells me what I needed to know. Editing in Divx = bad. I converted the clips to mpeg2 at 5000kbps (excessive, but it's temporary and I didn't want to lose any details) and dropped those into VS and everything was much better. Audio is synced when I playback the project! VS responds much faster too. You weren't kidding about the evils of divx for editing!

My downloaded files were probably extra troublesome because of their low bitrate. 180 MB for 7 minutes (Ken) vs 350 MB for 45 minutes (me)! In the future I'll convert any divx clips to mpeg2 and work from there.

Can I (where?) get a codec to allow my PC to playback H264 files? I encoded a movie in it but only the audio played when I loaded it up in windows media.

So if I want to post a video on YouTube, which recommends using the DivX format, I should render my avi clip to an mpeg2, then convert that to DivX using their converter. But I'm not clear on the last sentence, Ron. Why would I then go back to the VS Share>Create Video File? Or are you saying that is what you did for comparison?

From what I'm seeing, people have better results converting Divx files to mpeg2 if the original is in Divx and they need to edit (which was my case). If you have a file already in avi (or mpeg2), then you can work on that fine and use VS to convert it to Divx as the last step, after you've done your editing. That's where the Share->Create Video File comes in, as the last step, choosing Divx as the output format. Or you could use the converter that comes with Divx to do the conversion to Divx
