When should I use detelecining during transcoding?

[kbyrd]

I'm viewing content on a 1920x1080@60Hz TV connected via HDMI to an HD200. I use handbrake on Linux for most of my transcodes. As I rip my collection, I'm confused about when I should turn on detelecine.

For source material, I've got either BD disks of movies (all originally 24fps I think) and DVDs with 24fps (movies or TV where handbrake still says it's 24fps), or DVDs with 30fps (other TV).

I could leave the default detelecining engine on all the time, but I'm trying to eek out more transcoded frames per second and turning things off that I know aren't helpful for a given source (especially something like a big BD transcode) will help.

If I leave Handbrake's framerate setting as "same as source" and the output file is 24fps, what gets displayed on my TV?

If your TV is a 60hz (fps) tv then it converts all content to it's native frame rate. If it supports 24fps and converts it to a multiple of 24 (48,72,96) depending on brand then that is even better. I'd leave everything set to same as source and let your TV convert the fps to it's native format.

Ok so for sources that are 24fps (which many current DVDs and BD seem to be), I'm better off letting the TV do the work? I guess that was the essence of my question, does the TV or the HD200 convert, and when should I try and convert hard-telecined 30fps sources back to 24fps?

Ok, I think I better understand this now. If I run across a DVD with an 30fps, and I know the original was really 24fps, then I'll turn on detelecining.
