24p VFR and Sony Vegas

[booggerg2]

Hi I'm renting a couple of HVXs this weekend for a music video shoot and lemme tell you the information on this forum has been extremely helpful in clarifying all the complexities of this camera.

I understand the "Frame Rate Converter" workflow for achieving slowmo in FCP with 24p footage.

However, what is the 24p slow-mo workflow if I am editing with Sony Vegas?

I'd like to shoot 24pN for slowmo but I need the audio to edit with.

Any suggestions?

thanks
Yang

Record the audio elsewhere, you will have to.

UNLESS, youre shooting 60p 720p, but at that native framerate. Then it will record sound. (not the 24pn mode, with the "overcrank" aplied) but if that s too slow for you, shoot 48, or 36 frames, but record sound elsewhere, DAT, or another miniDV cmaera, for the sake of sound synch, use a clapper.

the 720pn footage will paly back at the proper speed in Vegas, no need for frame rate conversions. but you MUST have Raylight installed. MUST! other wise vegas cant read panasonic MXF files. Cineform, will work too, but its taxing on a computer. Editing the lowres proxies of Raylight is so Efficient. its like cutting DV.

Thanks for the reply.

I understand that 24pn will not record sound. Therefore I want to shoot @ 60fps in "24p" mode to get the sound. Is there an equivalent Vegas workflow to the FCP's "Frame Rate Converter" workflow for working with "24p" VFR footage?

**Edit**

Just read your post again: When you said shooting 60p 720p do you mean having the camera in "24p 720p" mode (not 24pn) and going into scene files and select 60fps? This is the same thing I've been saying.

if you shoot 24pn @24 frames persecond you get sound. its when you under or over crank that sound isnt recorded.

shooting 24p "over 60" as a 2:3 pull down. will give you no benefits. its just a formal way of getting some nle's to recognise the footage though all editors now suppot the 24pn stuff.

your best bet is to shoot 24pn and do your over ccranking with external audio capture.

But say if I want smooth slow-mo and I shoot footage A in 24p mode at 60fps. Can I then configure Vegas+Raylight to allow Vegas to recognize footage A as been shot at 60fps and the end result on the timeline would be a clip with smooth slow mo?

I don't we have enough time to get an external audio capture together for this weekend.

The 60p function is really confusin on paper...... theres three ways of capturing 60p. 1 is, native 60p w/ sound, where playback is a full 60 FPS. and theres, 60p "overcrank" which natively plays back at 24fps, but "slowmotion".


then theres a third format, whic sometimes causes confusion, and thats the 24p in a 60p stream. thats just normal 24p though, with sound, like the way the DVX records 24p in a 60i stream. its a pull down. if yo uslow that down in post you get a weird choppy playback.

if yo uwant slomo with audio, shoot, Native 720 60p. leave 24p out of the equasion. then in post, slow that footage down, to 40% and it will fit nicely in to a 24p cadence with slowed down audio.

Would this slowed down clip at 40% be the same temporal quality as an overcranked 60fps clip shot at 24pN? THanks!

**EDIT***

After reading the HVX200 manual again, it seems that the most flexible mode to shoot in is 720 standard recording(This allows me to over or undercrank the footage in post). In the manual it states: VFR is available in these formats: 720/60P, 720/30P, and 720/24P. What is the difference between shooting an overcranked 60fps clip in the 3 different recording formats?

I assume a clip shot in the 720/60P format is tagged to be played back at 60fps so the playback speed in NLE will be 1x ? However it sounds like your recommendation is shoot in this format and then slow the clip down in NLE? I so do I then still need to change the frame rate to 60 in the Scene File menu before I start shooting?
