Hey guys,

I am trying to finish a project that was recorded at 1080i50 and 1080i60 by mistake. I burned a DVD and some of the footage looked over-pixelated and kind of jittery.
I was told that I should convert all the footage progressive and then either everything to 25p or 30p.
I was also thinking converting it to 24p as a final product but this is the first time I am dealing with something like this so I am kind of new.
Does someone has any idea? Any previous experiences like this?

Thanks,

It sounds to me like you're in for a bit of a bumpy ride. 50i and 60i don't play nice if you're trying to intercut seamlessly.

You have been told correctly that going to 25p or 30p is a good idea. My recommendation would be to convert the 60i stuff to 24p and then speed it up to 25p. Simply convert the 50i stuff to 25p.

Your mileage, however, WILL vary and it takes a long time to get this stuff to do what it is told. I recommend you try a program called "DVFILM Maker" www.dvfilm.com - it should do what you need, but I have only ever used it for 50i > 25p. I think they have a seperate program called atlantis which does frame rate conversion.

If you have a post house near you it would probably be better to consult them, I'm not really a specialist.

Also, what are you using to edit and burn? Theoretically speaking if you're doing it right then at least half of your footage (either the 50i or the 60i) should look fine, the rest will not.

Hey James,

Thanks for your response.
I am using Compressor (Apple Pro Res for interlaced material HQ)to convert the footage and DVD Studio Pro to burn.
I will still check out the program at dvfilm.com and, yes, it takes a looong time to get this done.

thanks again,

p.

One other thing.
When you say speed the 24p up to 25 you mean doing it on the Atlantis software? What is the difference if I convert it with compressor?

Thanks

I have only limited experience with compressor, not a positive one either but I put that down to very rarely using it. DVFilm Atlantis is designed ONLY to do this sort of conversion, so one would expect it to be very good at it. That's pretty much it.

I tried to use the Atlantic software but it doesn't work with HD material. Or is that I download the wrong software?

That might be a problem with the software, as mentioned I have only ever used DVFilm Maker.

There is another program called Virtualdub, but it is designed for PCs, I recommend you search the forums of that program as someone there might be able to help you.

However, I really recommend finding a post house near you as they can better assist you.
