Ulead DVD Workshop 'Deinterlace output' ; Joint Stereo

Did a search, couldn't find the answer. Capturing from TV using ATI TV Wonder VE so I can transfer to DVD,

should I leave 'Deinterlace output' unchecked?

...or should I CHECK it and select 'Upper Field First'?

Thank you.


Also, should I use Stereo or Joint Stereo and why?

EDIT: Time to finally answer correctly those questions from 2004:

• Encode Interlaced, do NOT use De-Interlace.

• Default field order: * IMPORTANT * If using an ATi capture card, SET the field order to "UPPER FIELD FIRST" because that is a REQUIREMENT for ATi cards for all video captures. Captured videos will be jittery on those capture cards if "Lower Field First" is selected (even if "Lower Field First" is "Detected").

• Use stereo for two channel RCA cable captures, and read this:

Leave it unchecked, unless or until you know what that means.

No. TV broadcast is 'Lower Field First'.

For Stereo, left (L) and right (R) channel are encoded separately.
For Joint Stereo, L+R and L-R are encoded.

Unless you are using very low audio bitrate, you won't notice the difference in either way in most circumstances. For music programme, use Stereo, for others, use Joint Stereo.

It's for regular TV programming, 224 kbps and you say use Joint Stereo for that and leave 'Deinterlace output' unchecked, OK thank you.

Edited post #1 of this thread with correct answers.

• Encode Interlaced, do NOT use De-Interlace to capture MPEG-2.
(If the source is a High Definition signal, then use Progressive or Frame-based Source instead of Encode Interlaced.)

Since an ATI AIW VE can only capture interlace NTSC the answer is always don't deinterlace if a TV (SD or HD) is the target display. Deinterlace only for internet distribution or for extreme file compression.

Hardware deinterlacers built into progressive TV sets will do a better deinterlace than your software now and better yet in the future.

The only progressive coming in over the air these days is from abc and fox over ATSC. Everything else is interlace. DVD is a different story. Inverse telecine is a different story.

Filed order selection is device dependant, the golden rule is DV devices like a DV cam or Canopus converter will be BFF. Devices like the ATI AIW's and other common non-DV capture cards will be TFF. More here: https://forum.videohelp.com/viewtopic.php?t=257631

• Encode Interlaced, do NOT use De-Interlace.

The Pros & Cons of using the Progressive Source setting and CHECKING Inverse 3:2 Pulldown

Inverse 3:2 Pulldown should only be CHECKED in combination with Progressive Source setting. This should only be used if the source is standard TELECINE with continuous cadence from either a standard or a high definition signal.

* Pros: *

• Smaller files (with more bits available per frame) created quickly on the fly, allowing multiple movies to fit on one DVD at higher quality.

• Captures may look better on computer displays.


* Cons: *

• The source may have a break in cadence, in other words there may not be a continuity of pattern required for this setting to be used, resulting in frame disturbance.

• These errors may be due to a temporary field reversal (bad edit) or due to special effects that weren't shot on film. Therefore, if the source is not pure, noticeable pauses or stutters in the video can result.

• This may not be as useful for some Progressive DVD players and HDTVs which are designed to switch between telecine and adaptive deinterlacing quickly.

• If this is not done on the fly and is instead done by reencoding later, original capture can be preserved to fix any errors.

• Resulting errors may look far worse than Telecine viewed at 1x speed on computer displays this is designed to help with.


TELECINE can be recognized by using a program that can show individual frames. Look at five individual frames in a raw to see if interlacing artifacts show on the 4th and 5th frame. There should be 3 clean, artifact-free frames followed by two with interlacing artifacts. If interlacing artifacts are visible in all five frames (or not visible at all), the source is not telecine.

Telecine with continuous cadence is found on video that has been transferred from film. Telecine sequence (cadence) is interrupted by commercial breaks, special effects, cut edits, title overlay, conversion and speed up done to allow for insertion of more commercials or to fit the program into a given time slot.


Remember that Interlace artifacts clearly visible on a computer display do not show up when a DVD player is used with standard TV or an HD TV.

Deinterlacing software player can help with displaying minimal artifacts on computer displays.
