Thanks Ian.

I guess I'm wanting to get a wee bit more quality than just going with simplicity. And I'm wanting to learn at least the path to "better".

My biggest concern is getting flow showing with 24p, or at least an option to improve or deal with that footage so it sits well with my 50i output.aybe I'm asking too much?

Thanks Ian

I guess I should also ask if you are set on wanting a 24p dvd output, and why not 25p or 50i? Is it a pal or ntsc DVD player that it will be played on? Are you in the USA?

Assuming you really want 24p and not 25p:

De-interlace all your 50i footage to 25p using the free YADIF plugin. Use a batch render tool, I'd go with Peachrocks Multirender myself.
Then using Vegas retime the 25p to 24p.
Use a good DI, choose whichever you prefer. Sony MXF at 50Mbps is pretty good and edits easily.

Avoid shooting 30p, that is a bear to convert to 24p or 25p. If you must then avoid Vegas, use AE's optical flow to do a decent frame rate conversion. You might still be able to get GenArts OFX Speedo plugin for Vegas, if so you could use that but remember it is a free beta.


In general, I'd get all my ducks in a row, everything 24p before I started editing.

Once edit finished making a 24p DVD is a piece of cake, just keep in mind it will be 720 x 480 aka NTSC. Vegas can quite easily add pulldown to get 60i although I'm pretty certain the DVD spec supports native 24p on a DVD without pulldown.

Bob I don't want 24p, but it is what the Canon 40 delivers - period.

So, the idea is to prepare all footage to 24p prior to any editing and then finally produce a 24p DVD. I've use other advise to just throw all media on a 24p project Timeline and let Vegas get on with it.

Thanks Bob. In reality my head's been turn by the optical options of this consumer camera. My heart dropped when I got to this 24p info. And of course it isn't 24p it's 23.xx something.

Cheers

"Bob I don't want 24p, but it is what the Canon 40 delivers - period."

Be aware, if the camera uses a CMOS sensor you may strike the same issue I've had shooting 23.97 in 50Hz land with rolling bars in the frame due to the difference between discharge lighting's 50Hz and s4-. Switching the camera to 25p fixed the problem.

Ir is extremely easy using Vegas to convert 24p to 25p. This is the same as is done to all movies for broadcast in PAL land. Your movie will run 4% slower but no one one will notice and the new pitch shifting algorithm in Vegas handles the audio perfectly as well. There's no resampling of the video, no skipped, blended or doubled up frames. If you just drop 24p into a 25p or 50i Vegas project, good luck, wierd things can happen. I once tried to untangle such a mess and it really was impossible.

Bob.

So, the guts of what you are saying is:

A] Pre-convert ALL 24p to 25p in a Pre-Project veg?

B] Do NOT mix the 24p on the same timeline as the 50i?

Is that a "yes" to both A] and B] ?

Cheers

Grazie

That's why I was asking whether you wanted 24p output, because I thought it might be better to conform the 24p stuff to 25p/50i than vice versa. It can be done in Vegas on the timeline without the deinterlacing transcoding step. All you have to do is put your 24p clips on the timeline 25p/50i and speed it up in the media properties. Adjust the playback rate to 1.043. That should be correct for conforming 23.976 to 25.

Ian, thank you.

I want to eventually play out on PAL DVD. So that would be 25fps. I'm wanting to mix the Canon40 output with my CanonXF300 output - yeah, I know sad . . . - so I'm now testing your PB of 1.043 and doing the Vegas Burn from Timeline DVD for 16x9 720x576-50i (PAL).

Cheers

Grazie

One of the best tool for converting footage from one frame rate to another is IMHO
is HDlink from Cineform .
I use it exclusively when converting 25p footage to 24p for bluray and also upscaling hdv to full hd. If you have a copy of it, it is worth trying.
I always convert all my footage with that before starting to edit.

best wishes john

"Is that a "yes" to both A] and B] ?"

Yes.

There is somewhere in the dungeon of the Knowledgebase a paper on how to do this with precise frame accuracy.

Ian's method of changing the playback rate is probably accurate enough, the SoFo recommended method involves measuring how long the clip is in Absolute Frames on a 23.97 / 24.00 timelines then changing the project to 25fps and stretching the clip until is the exact same number of frames long.
Both methods do the same thing, it's only a question of accuracy.

Bob.

fwiw, I have a Canon Powershot (not the SX40) that only shoots in integer framerates. i.e. 30p is 30.000 fps (not 29.97 fps.) It might be worth doing a MediaInfo on the source footage to confirm its actual framerate.
