A problem with Video

[SPK8000LG]

Ok i have a Divx AVI file with sub titles hard encoded. I chaged it to VOB DVD video files using Avi2Dvd. I burned using a few diffrent programs so i dont think its the burning problem. WHat is happing is the top and bottom of the video is choped off. Like the subtitleing its self is half off the screen if that makes any sence. If anyone had a sulation to this problem that be great also im trying to join like 6 files to make one long VOB file problem is Avi2Dvd wount join AVI of diffrent resualtion. Whats the best program to resize the AVI file? TY

[SPK8000LG]

Update Whats happing is AVI2DVD is changing the resolution of the file. It starts as 640x480 but the resualting VOB file is 704x480. Whats up with that?

[gadgetguy]

640x480 is not a DVD compliant framesize so AVI2DVD resizes it to the closest compliant size.

Read "What is DVD" on your left.

Ok, But then how do i fix the subtitle problem? Not only cant i read the subtitles(i only see the very tops of the files) everything kinda looks streched. Any help?

[gadgetguy]

What's going to be required is to resize the video and add borders to compensate for the overscan. I don't know anything about AVI2DVD since I don't use it, but I suspect that it can't be done in that. (Anyone correct me if I'm wrong.) Virtualdub can do the resize/border function, but it won't encode to DVD. For that you'll want to frameserve to an mpeg2 encoder, (TMPGEnc, CCE, QuEnc, etc.). Alternatively, I presume you could save to AVI and use AVI2DVD to create your VOBs.

Ok i got Virtualdub. How do i do this. Theres lotta options. It also says my audio might be out of snyc by 500 ms. Dunno how bad that is

[gadgetguy]

You'll want to use the Resize filter under Video/Filters. It may require a little experimenting to determine the optimal settings to have the subs fit in the screen , but start by resizing to 600x440 using Lanczos3 filter mode. Then click on Expand Frame and Letterbox and define the width to 704 and height to 480. As far as the audio, this can get pretty involved depending on the source. What exactly did the warning message say?

[SPK8000LG]

Says its detected a i,proper VBR Audio Encoding. Says i may have a 5247MS skew from video stream. Im gonna try what u just told me many thanks

[gadgetguy]

VBR audio is something I've never had to deal with, and from what I've read, I don't want to.
I think you'll need to extract it to a CBR wav and may need to make timestretch adjustments and will probably need to adjust the audio skew as well. Hopefully, someone with more experience with VBR audio can jump in here and help.

[SPK8000LG]

Hehehe Right now im just converting the resaultion and buring and seeing if i even notice the audio skew. Whats the best program is best for me. Right now im uising Virtualdub and AVI2DVD and then nero to burn. Anything easyer here?

[SPK8000LG]

Woaaa just fished using Virtualdub why ohh why was the file it made 30 gigs !!!! Holy crap. This is only for a 23 min file. Whats up with that!!!

[gadgetguy]

You saved to an uncompressed avi. This is the default in Virtualdub and perfectly normal. To select a compression codec open Video/Compression.

Cool that did the trick one last question. It seems the sides of the video are slanted. Like the video is allmost triangle shape. Its bowed in at the top. Hope that makes sence. Any ideas?

[Faustus]

SPK8000LG, in the future please try to use a title that actually says something about the problem. Almost every post here is a problem with video

I'm not sure I understand, is this something that happened during the conversion or is this problem displayed in the original? It would help if you posted a screenshot.

Also, Flaystus is right. You should use a more descriptive title. I suggest you edit the original post and change the title to something like "After AVI2DVD subtitles cut off", or similar. In the future this will help people that are searching for an answer to the same problem .

The problem im having seems to happen after i use Virtualdub. Its like a geometrey problem. I sides bow in at the top of the picture. I tryed it on 2 diffrent tv and 2 diffrent DVD players. Funny thing is watching the VOB file right before i burn it i cant tell if its there. Its hard to see on the computer screen but very annyoing on the TV. Any ideas?

[gadgetguy]

I'm guessing that the problem exists in the original Divx file but you don't notice it. Again, a screenshot would help alot here, so I could see what you're talking about. I've used the VirtualDub resize filter countless times and it has never distorted the picture in the manner you describe.

Now you know why televisions overscan. It's to hide the faulty electronics.

Ok how do i take a screen shot? I tryed print screen nothing poped up. And do u think its the CRT TVs geo problems? I dont have an lcd to test it on. id also liek to note is i dont notice the problem till i play it on the tv

[junkmalle]

Ok how do i take a screen shot?

Open the file with VirtualDubMod. Use the slider (or arrow kesy) to move to the frame you want. Select Video -> Snapshot Output Frame.

I tryed print screen nothing poped up.

PrintScreen copies the screen to the copy/paste buffer. Open a paint program and paste into a new image, or an existing image. Use Alt+PrintScreen to copy only the topmost window to the buffer.

And do u think its the CRT TVs geo problems?... i dont notice the problem till i play it on the tv

Almost certainly the TV then. Burn a grid pattern to a DVD and play that. You'll probably see a similarly distorted picture.

[SPK8000LG]

Looking now at the pic the image is perfectly squre so there no reason to post it. WHats can i do to fix this? Chage the res a bit and make it wider? It seems to only need to move over another 1/4 inch and it be perfect. Gonna try 620x460 inside the 704x480 letter box see what i get. What cha all think?

[SPK8000LG]

that res didnt look to good hehe anyone tell me a workable res to fix for this "overscan" issue?

[junkmalle]

Try 640x436 in a 704x480 frame. Be sure to use a good resizing filter like Lanczos.

[gadgetguy]

In both of my posts that I asked for a screenshot I included a link to the tutorial for doing so. (Look I did it again, click on the word "screenshot". )

Overscan is not the issue. Overscan is a normal function of TVs. If the video has nice square corners on the computer but shows a "keystone" effect on the TV, then the TV is out of alignment. Unfortunately, most TVs no longer have controls that will allow the average consumer to make those adjustments. You've probably never noticed the problem before because overscan covers up the edges of the picture so you can't see that it's out of alignment. In this case your original video was made incorrectly because it did not allow for the overscan that exists on all TVs. That's why the subs were cut off in the first place. "Correcting" the video to account for an improperly adjusted TV, IMO, is just... wrong.

I hear Walmart has new tv's for under $100 at a decent size.

And the probably have similar geometry problems!

[SPK8000LG]

So if i had an lcd or plasma this wouldnt be happing? Here a screen shot Im trying that res now, Well see how it turns out

[SPK8000LG]

Looks good on my computer ill burn it and gey back with you all after work

[SPK8000LG]

Great! That last combo of 640x436 in a 704x480 frame looks perfect on my TV. I want to say thanks to everyone one for there help. Especially gadgetguy and junkmalle. One last question. What program (right now use AVI2DVD) give the best quality. Not to worried about encode time. Just want to make sure it looks good. Also it have to be free cuz im cheap no water marks placese

[SPK8000LG]

Also is there a way to Batch convert in Virtualdub?
