it might be a field-order issue.

What was your source video (how did you capture)? List all the devices used to acquire the original source.

Try to maintain the same "field order" throughout your entire process (capture/edit/encode to dvd -- if your final format is intended for an interlaced display like your TV).

thanks for replying

ok, I captured thru Radon card, The camera used was cannon Gl2, to mini dv. Q: when capturing the footage what should my settings be. The film needs to be NTSC for tv airing. I have a seperate playback monitor which is a TV to show me the tru image that will come from the Playback file.
Should I set up the feildorder to A before capture or after capture under properties

Does the Radeon card have a firewire connection, or are you using an analog connection (S-Video or RCA)?

If you are capturing via firewire to dv .avi's, your field order should be "Lower" or "Bottom" field first. And all subsequent work with that video should be the same.

If you are using some sort of analog capture, then it might be capturing "Upper" or "Top" field first -- check with your radeon manual.

To get the best out of your camcorder, I would target capture using Firewire, and capture dv .avi's to your hard drive (will need about 13gb for 60 minutes). You might also have a 4gb filesize limitation if your drives are Fat32 (NTFS will let you go higher than 4gb files).

I captured thru the radon expansion analog connector for rca input to connector to HD. I will check the radon manual. when you say upper or top field first are you meaning frame based

Hi,

Capturing through RCA is greatly lowering your overall quality from the start (at the acquisition step -- imho).

If you go with a firewire connection (given you excellent camcorder), you should see alot of improvement!

Have a look at "Frames and Fields" here (and other topics):

Thanks A bunch I will start there. I have the ability to imput footage from a dv connector sounds like that will be my best bet

one last Q so inorder to correct this issue should I recapture all the footage and set the properrties to feild orderA?

It depends on how you plan to re-capture -- either through analog (like RCA connection), or via firewire to dv .avi's on your computer.

Another thing that "might" be confuse things is Ulead's use of "Field A" vs. other manufacturers' use of "Field A." In older Ulead software, Field A was used for "Lower Field" first (not sure where the cutoff is, but VS7 is about that time). In later versions of Ulead software, they did away with "Field A", and instead call it "Lower" or "Upper" field first.

I would now prob use a firewire DV cable to the computer. So as far as the fields care concerned, my choices are frame based, field A and field B which road should I take?

if you capture to dv .avi's (via firewire), then you won't have the choice for Field Order -- it will capture it as lower field by default....

ok but if I go analog should I go Field A if I choose it it will reset the cache will it solve the wavyness when motion occurs in video?

GeorgeW · Post by **GeorgeW** » Mon Jun 06, 2005 12:35 am

if you go analog with the RCA connection, I think you should choose Field B (Upper Field first). But that's just following a "generalization" that analog captures tend to be "Upper Field" first -- you should check with your capture card documentation to be sure.

ok thanks for all your help in this matter

Your welcome

Just remember that what Ulead used to call "Field A" (Lower Feild) and "Field B" (upper field), other software might call them the opposite (so other software might consider "Field A" as Upper, etc...

The best thing is to go by the "Upper" or "Top" designations (these will be consistant across different software).
