Uncompressed SD 8 bit in DV timeline – Blurry/Aliased
I have a DV NTSC anamorphic timeline and took some AIC HD 1920×1080 and converted it to SD uncompressed because I could downsize it any other way where it wouldn’t look completely aliased.
I originally wanted to take the AIC straight to DV NTSC but failed after many tried of different settings. Anyways, it looks great in uncompressed 8 bit and ends up with 720 x 486 as the dimensions.
When I bring it into the timeline and bring it up in the viewer it is very fuzzy looking. In the Canvas it is slightly moire on the edges after a render.
Any ideas?
I had to convert a downsize a bunch of HDV clips for this timeline and these last few that were captrued to AIC instead of HDV are proving to be a nightmare.
Thanks

Well, one step closer. It spits it out fine when I change the compressor to uncompressed 8 bit.

Hi Elijah,
Avoid to work in a DV sequence unless you go to print to DV tape.
And work in 720 x 486 only if you go to print to DigiBeta.
Set your sequence in ProRess, “Render all YUV material in High Precission ..” “Motion Rendering: BEST” if you want to get a decent downscaling in FC.
Cheers,

Hey Rafael,
Thanks for the tip. I was using uncompressed and that was taking quite a while. I shall see how the Pro Res treats me. I have DV clips, HDV clips converted to DV and Hi-Def AIC converted to uncompressed in this time line now.
One thing I don’t get though is the settings in prores. DO I check interlaced bottom field first?
I want to take a prores master out of this sequence and off to compressor for DVD.
What is weird is that none of the clips appear to be interlaced to me.

If you go to DVD you need to work in 720 x 480.
If all your footage is progressive you can work in a progressive sequence, whatever the codec you set.
But you really need to know the field order of your footage first.
Put the canvas at 100% and look for frames with movement to see if the stuff is interlaced or not.

Thanks for your help Rafael. Gonna pick this back up tomorrow and go home to sleep for a few hours.
One question, if everything plays on a DVD then it means everything ended up being interlaced right?
Cheers

If the picture is progressive or have been deinterlaced, it doesn’t matter how you render it and where you play it, it will look progressive.

Let’s say I have a finished DVD and a put the DVD into a 15″ crt and also another Toshiba 22″ LCD with built in DVD the picture looks pretty good on both of them.
Would progressive be noticeably visible on a DVD with one of those configurations? What would I be looking for when playing progressive footage back on a DVD player?
