Is This An Encoding Issue?

[wetcamelfood]

Hi, hope someone here can help:

 

I've recorded some shows off TV, with the DVD recorder I have hooked to my TV and when I play hat DVD back on that it looks fine, but I wanted to copy the disc to my computer so I could chop off the ends/commercials etc. then reburn it so when I watch the disc I burn from my computer, it'll just be the show on the disc (which is what I want).

 

Now, after copying the VOB's to my computer, I dump them into VideoWave, do the edits, output to MyDVD to burn etc.

 

Then when I play the DVD I made with Roxio on my DVD recorder that's hooked to my TV, it looks great when there are still shots, but when there's I guess, what's deemed as quick motion, like the camera panning across a landscape, a car driving down the street, someone walking down a hallway close-ish to the camera, fight scenes, etc. it seems really jittery on the borders of those moving objects.

 

I've made discs in MyDVD using Fit To Disc, SP, LP, etc. the same thing happens each time.

 

I've done this on other programs like Adobe Premiere Elements 7 but I'd prefer Roxio because APE7 takes too long since I have to go VOB to AVI to MPG etc. & don't have to on Roxio and surely Roxio can cope with this problem the way the other programs can?

 

Is this an encoding issue? Just seems strange it looks perfect when things in a scene are still or pretty still. Is there some sort of setting I need to change?

 

Any ideas please let me know as I have a lot of stuff I want to record but don't want to proceed until I can resolve this so I don't have to do them all over again later but want to resolve this soon so what I need to get through doesn't pile up too high. Thanks in advance for any helpful replies.

Less than about 2 hours and then you see major loss of quality. Why do you want to squeeze all that video on one disc?

 

Do you have a DVD player that will play DivX format. If so, consider that. The format is highly compressed and you may get 6 hours or more on a disc.

 

Also, there are a lot of people with real issues; is this now turning into an esoteric exercise?

 

My equipment can't do DivX.

 

I like to record movies off TV (for my own personal collection, nothing more) and I don't want to have to get up in the middle of the movie to change discs. The longest movie I have & like is 3 hours so I don't need to get anything longer that that on a disc (in case this helps for my needs).

 

Don't know what you mean by "esoteric exercise".

For longer movies, try burning to Dual Layer media. The quality should be much better.

How long in time is the video you are working on? A standard 4.7GB DVD will hold 60 minutes of video at best quality. Any more and the video has to be compressed with a resulting loss of quality. SP and LP of course give lower quality. Fit-to-disc propably is the worst, none of the gurus here recommend it. A better way to get more then 60 minutes on a DVD is to burn the video to a image (iso) file and then use Video Copy & Convert to burn that image file to DVD. VCC seems to do a much better job of transcoding the video to a DVD then Fit-to-disc

We used to hear of that all the time when the Video Card wasn’t up to snuff.

 

Easy to test – MyDVD – Project Settings – Render, set it to Software.

 

Make a test burn (RW?) and see what happens.

 

The things Walt mentioned could have an effect too.

Yes, this seemed to work thanks, normally about 2 hours but can be an hour, can be three hours, strange how "Fit to" doesn't work you'd think that'd be the best choice for space and quality, guess not though, hmmm...

Well, I found "pre render menus in preview" checked in Project Settings, is that where you meant? Doesn't sound like so let me know, maybe I'm in the wrong place.

You can also go to the top menu in MyDVD, select Tools>Options and put a dot near software.

OK I found it this way, the thing now is the jittering moving objects have stabilized but the picture now looks kind of "pixel-y" like when you burn an FLV file to DVD, is this because the mpg export setting is "smallest file size" by default? I worry if I make the quality better either it won't fit on the disc or it'll take all night to encode/burn. Any thoughts/suggestions?

[ggrussell]

'Smallest files size' will also give you the worst quality. It's simple math. There is only 4.7Gb of 'bits' on a single layer disc. Regardless of the video length, it must fit into that space. At best quality, you can get ONE HOUR. Doesn't matter what software you use. That's it. Anything longer than that, the video must be compressed or the resolution lower or both. Higher compression and/or lower resolution will result in poorer quality video.

Yeah I thought this, just trying to figure oiut how long "normal" & "better" will give me...

This is where Videowave and MyDVD differs. Someting I hope will be added to the next version.

Videowave:

MPEG 2 for DVD - Best is 720x480 @9Mbps, Better is 8Mbps, Normal is 7Mbps. Smallest Size is 352x480 @4Mbps which matches MyDVD LP mode.

 

MyDVD:

HQ = 720x480 @9Mbps, SP=352x480 @6Mbps, LP=352X480 @4Mbps

 

These are defaults and personally, I think some are wrong or should be different. For Videowave, there is too LITTLE difference between the settings. In MyDVD, there is too BIG a difference between them. Not consistent.
