Thanks so much for the answers, much appreciated.

Just a couple things i wanted a bit more of clarity on that im still unsure of. Sorry if i repeat myself but unfortunately im not sure how this footage was put to 29.97 or 23.98. Can’t they both just be straightforward frame rate conversion vs. the use of telecine and reverse telecine?

How do i know that the 29.97 fps footage was not a frame rate change from PAL through an application or using a Teranex to the 29.97?

Does it not matter how the footage got to 29.97 and the reverse telecine will work to get it to 23.97 in compressor regardless of how the footage was processed? I thought Amazon would be fine would be fine with 29.97?

I figured most people did conversion in a program to their preferred destination frame rate vs using the Telecine.

Again thanks.

Firstly i want to say thanks to everyone contributing to this area of telecine as i’m having a few issues with it myself… Is inverse Telecine basically normal telecine and Reverse Telecine is the only other option?

I am in Canada so we are using NTSC

My issue at hand is that our content is basically all PAL programming and our post house captures our PAL tapes and delivers it to us in either23.98 or on occasion 29.97. I need some clarification on the point of Telecine as we are now delivering our distribution products to Amazon. Here is what i was written by their Video guy after he confirmed they want our programming as un touched as possible. Everything delivered to Amazon we are sending in Pro Res.

As Written by Amazon-
” You can check the header data in a video file really easily with MediaInfo which is a free utility you can find on the internet. If the content is telecined (has 2 combed/interlaced frames every 5 frames) we would prefer the content be inverse-telecined to return the content to a progressive 23.976fps on your end, before delivery.”

-Firstly when would i be using a telecine or reverse telecine on such footage or with the facts i put above about our footage would this mean it doesn’t require telecine in any way? My guess is the post house is doing a simple frame rate change from the Pal to the 23.98 or 29.97. I also will note that mostly all of our programming is interlaced according to the media info.
-When will i need to use telecine or reverse for such work?
-Since most of the our programming is interlaced whats the best way to make it progressive using MAC applications? Compressor? FCP?
-I believe our post house is no longer using their teranex machine to change our frame rates on our PAL content so i wondered if you could explain why the teraned is better then using a program to do the frame rate conversion

And one other thing in the spirit of using our converted material.

– I have done authoring projects using supplied 23.98 video and had no issues with compressing it in Compressor (to MPEG 2) and then ending the process in DVD Studio Pro. Why did that not need to be converted to NTSC to work as a playable DVD?

Again Thanks so much for your time all.
