Premiere Pro Conditional Support for HV20

[jmorton]

Go to Adobe Third Party Compatible Hardware webpage and it says it only provides Conditional Support for the Canon HV20.

Here is the lame comment they make: "24P recordings cannot be treated as 23.976fps in Premiere"

So what should an HV20 owner do or presume when working with 24p? :hv20-smilie68:

You remove pulldown first using this method, and then Premiere Pro will have no problem with your 24p video:

Alternatively, buy Vegas Movie Studio Platinum 8. Cheapest solution in the market that supports 24p (even if not officially).

You can also keep the original 24p in 60i footage from HV20 and edit in Premiere in a 60i timeline. That's what I did. I didn't bother to remove the pulldown. The result is just as good.

I installed the Pulldown.exe according to your outline (excellent work) and it works like a charm.

The first thing I do is remove the pull down. Then I guess I should start a new PP3 24p project and import the 24p .avi file. I'll be editing in 24p then.

Could you explain exactly what we are getting with this .avi file output from the Pulldown.exe? It is not uncompressed, right? And does it suffer from a generation loss? I'm thinking not.

But if you add effects and until you render you have not altered anything, right? And when you do output/export to the format of your choice this is only one generation loss, right? And how significant is this loss?

Can you explain how we can go into the set up as you explain in your outling and change to something other than Logarith? What might we want to change to and why? What advantages this might have?

Could we remove the pulldown to uncompressed .avi then create an intermediary and edit and apply effects using the intermediary then when we are ready substitute the uncompressed in the final edit? What are the steps to pull this off? (If it is not asking too much. Or you could point me to a good reference.)

Thanks.

exactly.


>But if you add effects and until you render you have not altered anything, right? And when you do output/export to the format of your choice this is only one generation loss, right? And how significant is this loss?

exactly. The loss depends on how/what you save. If you edit in 24p you should not save as HDV, but as h.264 or WMV or mpeg-4. That's the "user" format that you can share with others or devices. The uncompressed/lossless versions are only suitable for editing.

>Can you explain how we can go into the set up as you explain in your outling and change to something other than Logarith? What might we want to change to and why? What advantages this might have?

You can choose the Huffyuv codec instead of Lagarith, or uncompressed. But the method we provided via this forum to remove pulldown won't give you other choices (might do Cineform if you have the full NeoHDV installed though).

>Could we remove the pulldown to uncompressed .avi then create an intermediary and edit and apply effects using the intermediary then when we are ready substitute the uncompressed in the final edit? What are the steps to pull this off?

No. The method we remove pulldown must be an .m2t.

"No. The method we remove pulldown must be an .m2t."

I was unclear so I think you misunderstood me. I am saying that I intend to remove the pulldown from the .m2t file first. Then I intend to import this 24p .avi file into my 24p project.

But because the file is so large I would like to create an intermediate from it just for editing/effects processing to make this stage of the workflow go by much quicker and easier. Then when I have made all of my edits/effects I would like to replace the intermediate with the 24p .avi file and output/render from the 24p .avi file but using the decisions I made from editing the intermediate.

I hope this is clearer.

Can this be done and if so can you outline the procedure or point to a reference that explains how to go about this?

Thanks. :hv20-smilie03:

I presume then that when you are through with your editing you then remove the pulldown to output from a 24p file format.

If this is correct, I am concerned regarding any special effects work you might do. Would special effects work you make to the 24p still embedded in the 60i wrapper appear correctly after you remove the pulldown then?

How do you go about adding special effects in your workflow? :hv20-smilie51:

The .avi created by the removal of pulldown is SMALLER than uncompressed. So I don't see why you would want to create an uncompressed .avi file, because the resulted .avi Lagarith file from the pulldown removal is VERY suitable for editing. You just pull that .avi to your editor and you edit it, no reason to re-save it as uncompressed or other intermediate.

>I presume then that when you are through with your editing you then remove the pulldown to output from a 24p file format.

No, Premiere won't do it the right way. The 24p version of HV20 is a bastardized system (3 progressive frames followed by 2 interlaced ones), so I would not bet that it would be good. I suggest you remove pulldown at the beginning.
