Converting 23.976 to 29.97 with 3:2 pulldown using Compressor

[Eli Sanchez] “The client wants the video in 480×272 which are strange dimensions to me. Maybe this can account for the lower quality as well?”
Do you even need to add pulldown to this?

I’m actually not sure, I have to convert from 23.976 to 29.97, 480×272, and the h.264 codec. I’m not sure why the footage looks degraded maybe it is how it’s supposed to be given the specifications. I’m trying to find the best look possible for these specs. Any advice would help.

I highly doubt that you’d need an interlaced file for this. And do you really need it to be 29.97 if it’s going to the web?
I would try a few options.
Set the output fields to progressive and in the “retiming control > rate conversion” section, I’d try both better and best.
Best can get super gooey, but when it works, it works really well.
Better is sometimes the best option. It depends on your footage.

Thanks I will try this. This is going to be on small TV’s in doctor offices on the East Coast.

I’m intrigued by the suggestion of “Bottom field first”, which harks back to the DV days. Given that “Top field first” is the preference for interlaced HD for broadcast, surely that’s the one to pick? Or is “BFF” part of some interlacing secret sauce in Compressor?

For SD, NTSC.

Isn’t standard NTSC top field first like everything else except DV?

I’ve just run a test and Top Field first is definitely smoother, for HD (effectively 59.94i from 23.98p – just as a Nitris DX does on the fly). Bottom Field first looks just like old DV minus a field shift filter – jarring on movement on those frames containing fields from adjacent frames. My hunch is that it’s true on SD as well – unless you’re coming from and going to DV.
Good trick though – and with a decent deinterlace we have real 29.97p.

No. PAL has Upper first uncompressed SD, but lower DV.
All NTSC SD is lower field first.
HD is upper field.

HD is upper field.
