Jittery Transitions With Videos.

[Joe Photo]

Jittery transitions on moving videos. Is this fixed in Roxio 10?

 

I created my videos back in version 8 (and I'm still running version 8). Everything looks great except transitions to videos with moving subjects. They become very jittery.

 

I’m to the point where I burn to the hard drive with ISO files and then burn DVD’s with them.

 

What I’ve noticed is they look good when played thru the PC (with the DVD drive). Look good on the HD TV with the upconvert DVD player. Look really bad on the big screen older TV with regular DVD player.

 

I’d like to distribute these video’s to family and friends and almost all of them are using regular TV’s with regular DVD players so I’m sure the transitions will be very Jittery to them.

 

What would cause this Jittery problems, has Roxio 10 helped correct this, if not… is there anything else I can do to fix this?

What transitions are you talking about? Switch to software render, in MyDVD, and see if the problem clears up.

I tried that in my version 8, didn't change anything. I'd move up to version 10 if this problem is fixed. we have two computers that we can use and both of them do the same thing, so it's not computer related.

 

As for as transistions, basically... any time i switch from a either a stable photo or moving video to another moving video, I get the jitters (sounds like a drinking problem... doesn't it! ). It last for only maybe 2 seconds (end of first photo/video and beginning of next).

 

Since it looks almost perfect (you can still see residual affects of this problem... but only if you look for it) on the HD TV and the computer monitor, i'm wondering if it's a phase problem or could be a pixel problem? From what i've seen... roxio will only let you do 30 fps whereas a tv is 60 and a computer monitor is somewhere around 70 or 80 (the hd tv is a LCD tv so it's at 70 I think).

 

These are just thoughts running around my head as to solve the problem... not sure how accurate or if they are the problem. So, any other thoughts are good to hear too.

It has nothing to do with the fps. Those are standards for DVD video.

 

Have you tried putting a dissolve transition between the photo and video? Have you updated the drivers for your video card?

Standard MPEG 2 DVD NTSC is 29.97fps interlaced so mutliply that by 2 gives you about 60Hz. Sure there may be some LCD hidef TVs that may have higher scan rates for progessive (1080p), but the majority of what is sold is 1080i which will be 60hz just like the old TVs.

 

I have a 1080p monitor/TV 42" and it still only supports 60Hz. Progressive is mostly hype IMHO. I've looked at both and can't tell much difference.

ok... that would make sense (being that the 30 fps are a standard for DVD video)... after all, the video's are fine once you get past the first 1-2 seconds.

 

the transition i'm currently using is both slow dissolve and fast disolve. Even after the disolves are finished, the videos are still jittery. it's as if they are set to a standard 4 second jitteriness.

 

As for updating video drivers. funny... i'm sure i did on the upstairs computer. although.... not completely sure I did. and... the downstairs computer was recently updated with a new 512mb Rathion 2600 pro video card. i know I tried burning a ISO file to the DVD to see if that changed anything... but not sure if I rendered an ISO file from an MPG and then burned a DVD using that updated computer (i recently gave it 2 GB RAM as well).

 

.........

 

Since we talk about this, here's a link to one of the video's I uploaded on Myspace. It seems to have a different problem with the transitions... but I'm not so concerned about that problem.

 

 

My video created with Roxio

I watched some of the video. I didn't see any 'jittering', but the slideshow did seem to pause just a fraction before and after each dissolve. Have you tried switching to software render?

 

Open Videowave and load your project

Click on the menu TOOLS / Options.

At the top, you will see the Graphics test button. Does it default to 'hardware'? If so, click on the dot beside software and click OK.

 

Then try outputting the file again.

I had a similar problem but I cured it by switching from software to hardware render mode. This is back-wards from what what was previous experiencing and I can't explain it. I was also using only dissolves but I was making slide shows rather than video editing.

 

Open your video card's control panel and make sure that the performance is set to best and away from appearance. Also make sure the anti-aliasing and anisotropic filtering is set to program controlled.

Sorry, didn't get a chance to try anything this weekend (had guests over checking out the new baby and then worked on my brakes yesterday)... I'm going to try some of all you guys suggestions this week.

 

by the way, some simple questions....

 

What is Anti-aliasing and Anisotropic Filtering?

 

Also, why would software rendering be better than hardware?

In reverse order:

Software rendering does not rely primarily on the video card/chip to encode the video. You can get away with a lesser functionality card/chip and still get good results. The only thing you lose is some of the transitions (3D). Different people have experienced either faster or slower encoding using the software rendering compared to a hardware render.

 

Google for a answer regarding the terms. It is how your video card/chip handles some of the video display and encoding. Adjust them to software controlled using the card/chip control panel. Run the rendering test in Video Wave (top menu, tools, options) before and after changing the settings to see the difference in rendering time.

 

Children and brakes are more important than a fast reply !
