MF 5 patch for AV sync problem?

[rdhamm]

I have MF for Toshiba version 5.51.0119.0 SE 002
I have AV sync problem after trimming videos. I see patches for this problem for other versions. The only fix I see for version 5 is for Vista, but I don't see that it fixes the AV sync bug.

Welcome to the forums,

The version you have

5.51.0119.0 SE 002

is a Special Edition. These SE versions are tailored for specific vendors, and are sometimes further modified by the vendor, and are watered down from the full versions. They are more of a teaser to entice people to purchase the full versions.

The downside to the SE version, patches and updates will not install to them. We do have a sticky at the top of this forum, concerning updates for the SE version concerning Canon cameras, however I don't know of any for Toshiba versions. Steve, may be able to provide more insight, as he does own a Toshiba laptop that did come with this version. His major complaint voiced on the forums, is that Toshiba laptops for some reason does not recognize JPEG images.

You might check Toshiba's website and any support forum they may have to see if they have any updates/patches for this.

Next I would ask as to what the properties are of your Video clip(s)? For help on this Please Read this.... There are numerous video formats that are intended for distribution only, however may be edited at risk. One of the more popular problems is the OOS (Out of Sync audio and video). MPEG-2 used to be very difficult to edit without getting this OOS problem. Some users tend to use a special purpose program, such as Womble, to do any editing of MPEG files. Then use DVD MF to build and burn DVDs.

Yes, this came with my Toshiba laptop I bought 1.5 years ago. I have updated my profile with my system info. The audio files are .avi. The AV sync is okay if I do not clip the files. If I clip them, the sync is okay in the preview pane, but out of sync when I burn to disc. Hopefully, Steve can give further insight. Thanks!

AVI is a container format, unless they are the full uncompressed, which yields a whopping 65 gig per hour. AVI can hold numerous different actual compression formats, such as DV, DivX, Xvid. Could you right-click on a clip and select properties, then post what those properties are?

I have 3 different videos in my project. One was from my miniDV camcorder, so I'm suspecting it's DV. The other 2 must be DivX (that's the player that plays them).

[Ron P.]

The video from your miniDV should be DV, unless you've converted it while transfering or at some time before inserting into DVD MF. I will assume that it is DV. This should not have any A/V sync problems.

Next the other clips being DivX, will have the risk of A/V OOS, when you edit them. DivX was designed to be used for viewing on the web, period. There are some other things that come into play....

1. Are you trying to combine your DV and DivX clips into one video file? If so are the Frame sizes identical, the frame rates the same? The frame size for NTSC is 720 x 480 and for PAL 720 x 576 . These are the DVD standards for Standard Definition DVDs. The frame rates are (NTSC) 29.97fps, (PAL) 25fps. Your DV clips should meet those, however the DivX probably do not. They may have the frame rate at 30fps, 25fps, or any number that the original author wanted. The frame sizes may also be somewhat smaller, say 640 x 480. Why are these important?

Since your problem is with the A/V OOS, I'll focus on that. Lets say the frame rate of your DivX clips are 25fps. When you try to mix that with your DV clip, which has a frame rate of 29.97fps, one of them must be changed. If your project settings are set to that of the DV clip, the DivX clips must have 4.97 frames added to every second of the clips. IF the project settings are toward the DivX clips, the DV clip must have 4.97 frames cut from every second. In doing so, the sync between the video and audio will be lost. You would need a video editor (as MF is not much of an editing program) to split the audio from the video, and then manually move one in an attempt to re-sync them. This however is hit and miss at best.

If you're intentions are to create DVDs then all clips will be converted to the DVD standard prior to burning. DivX clips generally do not meet those standards and are more difficult to convert at the time of burning.

Use a conversion program like Super to convert your DivX clps to MPEG-2. Then use your converted video files in DVD MF. Better yet, I would create an MPEG-2 video file from your DV video file also, and then you would have just MPEG-2 video files to burn to DVD. The end result is that all clips must be and will be converted to DVD compliant MPEG-2 before burning.

Correct, the DV file had no sync problem when trimmed.
I don't think I'm trying to combine the DV and DivX clips into one file, but into one MF project (3 seperate clips in the Media Clip list).
DV clip frame size says 0x0 and 29fps.
DivX1 is 720x480 and 15fps
DivX2 is 800x600 and 50fps (COINCIDENTLY, THE EDGES OF THIS CLIP GETS CUT OFF BY MY TV SCREEN WHEN I BURN AND PLAY ON MY DVD PLAYER. IS IT B/C OF THE 800X600 FRAME SIZE? AND IF SO, HOW CAN I CHANGE IT?)
Both DivX clips were originally Powerpoint programs that I converted to video with Camtasia Screen Recorder. The audio was narrated in Powerpoint and transfered over.
If I convert the DivX clips to MPEG-2 as you suggested, will that solve my AV sync problem when I trim them?

[Ron P.]

Is your audio file a separate file and what format, WAV? Was it for one of the DivX clips or both? What you might have to do is re-record your narrative in DVDMF.

Your 800 x 600 video clip is being cut off because any standard definition video being viewed on a TV for NTSC areas must be no larger than 720 x 480. TVs, unless being viewed on a plasma, or LCD, have what's called overscan. This is generally 10-20%. So the TV is going to cut off 10-20% of the accepted frame size of 720 x 480. In DVD MF there is what's called Title Safe area. These lines show you the area surrounding that might be cut off by overscan. Keeping everything inside this border will insure it does not get cut off.

DVD MF will convert all clips to DVD Compliant MPEG-2, prior to burning them to disc. Converting your DivX clips before using them in DVD MF, will just lighten the burden placed on the program, and will increase the probability of things staying in sync. However if your audio is a separate file, it may not sync up even after conversion.

Trying to simplify this, you have clips that all play at different speeds. For a consumer program to know how to sync all these is not a reasonable ask. Power-Point and your Camtasia Studio clips are meant for PCs. PCs can play any frame sizes, at any speeds desired. Stand-alone DVDs and TVs, however are constrained to what the international communities have set for them.

So for each DivX clip, you should convert them to 720 x 480, 29.97 MPEG-2 video files. Then insert them into DVD MF and bring in your audio narration file. See if it is close to being in sync with whichever video file it is suppose to be. If not I would opt to redo the narration.

If you registered your laptop with Toshiba - every now and then you should get an email from them that contains links to updates for the various bits of software and hardware that came with your computer.

Because I have various full versions I didn't update mine (don't use it)
but will keep an eye out for the next email from Toshiba to see if I can find any links relating to updates for MF5.
