Rendering


latinangel_13@yahoo.com

Question

What settings should I use when I render a video to get a clear output? I have tried many settings in my EMC8 when I render and I have even put some custom ones together, but everytime I render, my video comes out all pixelated. What settings do you guys use to have a clear video output? :):huh:

 

Please help. I'm trying to render my cousin's wedding video I have put together for them to give it to him as their wedding present and I want the picture to be clear like regular videos and not all pixelated like it is coming out right now.

Ah.. that's why the final output is pixelated. Sounds like MPEG1 which is VCD quality. Always set your MyDVD project to 352X240. Otherwise it will be stretching the video to make it fit. When it comes to bitrate, just set to LOW. I'm still not sure about the conversion from MPEG1 to 2 and how that would affect quality.

 

For better quality, you need something that captures at DVD quality (720X480) like the DVC90 or 150.

 

Personally, I use a Sony TRV740 8mm digital camcorder connected via firewire and capture DV AVI only. I recently purchased a set top DVD recorder ($69 on sale) and have been experimenting importing those files into MyDVD. A little tricky, but it works.

max. resolution: 320 x 240

max. frames: 30 frames per sec

compression: proprietary

video formats: AVI, MPEG2, RealVideo8, WMF

 

What kind of input devices do you guys use?

That's what I figured. Those numbers indicate a quality comparable to a VCD production, which is the lowest quality disc you can make. It probably only looks good initially because of the proprietary compression it is using. Since the best type settings for dvd's use 720x480, when you try to use those files, the program has to render the file 'up', which will almost always result in quality degradation. The only thing you could try (I don't hold much hope for it myself tho) would be to change your project settings in mydvd for a dvd project to match the 320 x 240 and see if that helps.

 

For myself, I currently use a couple of Hauppauge WinTV devices. They only capture in mpeg2 however, and also use proprietary hardware encoders. So I cannot capture using the EMC programs. There are a number of other devices that others here use. I am looking to maybe get my hands on a Dazzle 90, which will be more compatible and has more capture options, like 720 x 480 AVI which is the best quality, especially if one is going to do any editing of the captured video.

 

Bottom line is, the dazzle 80 you have is old technology. It came out in the early, infancy days of home video work, and has quickly fallen behind. It just doesn't do the job when it comes to DVD quality video work.

Ok...I am capturing my video from a Hi-8 camcorder through the Dazzle DVC 80 device. So, the wedding video is on a Hi-8 cassette. When I capture the video through VW, the video looks fine on my monitor and even when I burn it to a DVD without editing it. The picture is very clear. The problem is when I render it after I have edited it. The final product is all pixelated. No, I do not rely on the preview. I render the file and then use MyDVD to burn it to a DVD and play it on my DVD player. The picture is distorted. I preview my rendered edited video on my computer immediately after it has rendered.

To what setting are you rendering your edited video? Why are you even rendering before you import into myDVD? If you do your editing in Videowave then you should be able to load your "unrendered" VW project directly into myDVD.

I have tried different rendering settings, such as the one for DVD output on Best Quality, and others and I always get a pixelated picture. What render settings do you use when you render to get a clear picture? I render my video before importing it to MyDVD because when I just to try load it unrendered to MyDVD and when I try to burn it, it says that there is an error. And sometimes the unrendered video does not even get imported to MyDVD. :)

First you need to determine what the properties are of the file that it captures. Is it 720x480, 352x480, 352x240 (or something else), and what is the bitrate, 8mb, 4mb, 2mb (or something else)???

 

It sounds to me like the video is being captured at a very low bitrate (high compression), possibly even mpeg1 rate, and only 'looks good' before editing because of the hardware encoding of the DVC 80 device (It's my understanding that that device cannot capture at the mpeg2 dvd standard for files). Because the file (likely) isn't already a dvd compliant mpeg2 one (it's substandard, high compression), if you do any editing, it will have to be re-encoded to meet the settings of a dvd, which means it is trying to render 'up' in quality (less compression), which will not work with video files, as that actually makes them worse (as you are finding out).

 

Since when you do not edit the file and burn it, it still looks ok, that leads me to think it is the low compression mpeg1 type of file, as it would not have to be re-encoded because you did not edit it. It is 'smart rendered', meaning just converted into dvd files.

 

I think your only options are to either not edit the file once captured, or get a device that will capture in high quality dvd compliant mpeg2 files, or even as DV AVI files (non compression). Something like the Dazzle DVC 90 would work.

Let's start at the other end. How are you capturing that wedding video from thee VHS/Hi-8/ DV/cd? Have you captured it as an AVI file? Are you using fire wire or the USB device that you listed?. I noticed that you listed the 85 USb device and that can capture as avi or mpg1. Don't even think about mpg1.. Is the wedding video on a DVD or cd? If the capture is not good, then no matter what you do with it, you cannot make it better. Is the video one that a professional did and now you are trying to edit it?

 

For best quality, capture as an AVI and edit it in that format - you'll need a lot of disc space. When you go to burn, juts pick best quality (not fit to disc) and make that iso file. The video should be almost as good as the original.

 

Also are you relying on the preview to see what the final DVD will look like. That's not a good idea. make the iso file and copy to a rewritable disc . that is the only way of knowing for sure.

 

If you can afford it, add more memory. Ste your computer to best performance in Windows, set the virtual RAM to at least two times your actual RAM. Shut down everything else running whan you are rendering.

 

What settings should I use when I render a video to get a clear output? I have tried many settings in my EMC8 when I render and I have even put some custom ones together, but everytime I render, my video comes out all pixelated.
