23.976 Interlaced Conversion

[jonaswray]

Hello, I wanted to know if somebody has some advice in converting 23.976 Interlaced video to DVD. We have CCE 2.67 and ProCoder 2. I have been getting very choppy/jagged video in default conversion. If anybody has any advice in any of the two I would really appreciate it. The more details the better.

Thanks

Flip field order ? or delete first field
Where did you get interlaced 24 fps ? from a camcorder ?

Hey Foo, Thanks for the quick reply. I did get the footage from a Panasonic DVX100 camera. How would I flip the field order or delete first field? Sorry, I really don't have alot of experience with 23.976 interlaced. Again thank you for the reply and sorry for the lack or knowledge...

In CCE there should be an option for line offset (I think that's what its called) or if you have an older version of CCE it will be labeld top field first. Enable this and it will crop the first scan line, effectively changing your field order. It does sound like you encoded with the wrong field order, so that should correct it.

If you still have the mpg you can just reverse the field order using pulldown.exe. Get the gui to make things easier.

Hey Adam, I have set the offset to 0,1 and NOTHING has worked for me, I have also used pulldown.exe with no success.

Beats me. Next time shoot it at 30 fps

I've never used Procoder for framerate conversions. Since you say its choppy, I guess it is just repeating frames to increase the fps to 29.97fps. This would surely look very choppy.

See if the program has any sort of 2:3 option that would perform an actual telecine. (repeat fields in a pattern rather then random whole frames.) If not, then you might have to use another encoder. TMPGenc has such an option.

procoder is the best for framerate conversions.

did you change the field order ?

try to de-interlace that, and then convert it to dvd.....should work.

[adam]

If the source is interlaced he should keep it that way. Deinterlacing will lose alot of quality.

i know....but.....

not really, if is done properly.....is like an xvid or divx file.

doesn't hurt to try.....I did a lot of dvd from divx files, and it is perfect....no jerkyness

[adam]

Deinterlacing pure interlaced sources like this will always result in substantial quality loss. You either throw out half of your scan lines or blend them together. He just needs to perform a proper telecine. Whether Procoder can do this or not I don't know, but deinterlacing should be the absolute last resort.

[jonaswray]

Hey Guys, thanks again for all the answers. At the point that I'm at now it would be ok if I lost some quality. I just really want to get this thing to work. All of you in this forum are my last hope to resolve this hahah.

Thanks again

Just try TMPGenc since I know it has a telecine function. Just load the NTSC DVD template and then on the advanced tab enable the 3:2 pulldown filter.

I find Procoder to be far superior to TMPGenc for interlaced sources, but I just don't know if it has a similar telecine function. If it doesn't, then its not going to work for what you need to do.
