Dogs in Floodwater (Slow/Mo).

Why Cinema Tools ... Just curious?

Awesome shots! I don't get sound when I do slow mo. Is it because I'm not using cinema tools?

I'm shooting 720p/24 at 60FPS. When I play back any altered frame rate I loose all audio.
 
Before I got the HVX I learned from Patrick Sheffield (Apple FCP Forum) that you could get really smooth Slow Motion by first using Compressor to convert 25 fps to 50 fps, then use Cinema Tools to Conform it back to 25 fps.

It just seems natural (and very quick) to use CT to conform 50 fps to 25.

Is there an easier way?

25pN, shoot at 50FPS, and it will automatically playback the MXF file at 25FPS. incamera overcranking.

That way, I'd be stuck with slow motion for everything. If I shoot my way, I can choose what speed to have the clip play back later.

Slightly more work but a lot more flexibility.

Nobody gets sound when over/under cranking check out the manual.... if you want sound you'll need to record it seperately and then add it in post.

Well I get sound!
(What you hear there is the ambient sound at the time of shooting)

Follow my workflow and (I hope) you'll have sound -

Record at 50 (or 60) fps.
Duplicate the resultant Media File, then use Cinema Tools (or similar) to convert it to 25 (or 30) fps. This will give you 50% speed but of course, you can vary it - recording at a rate halfway between the two will give you 75% and so on. The reason I duplicate the Media File is because Cinema Tools alters the actual Media File, so if you want to use at either speed, you must create a new file and save one of them as original.

Variable Frame Rate is explained very clearly and thoroughly in Barry Green's HVX Book:

If you record in Native mode (at a speed other than the default) you get no sound.

I use FCP and have altered the playback speed within the editor. I have compressor and cinema tools also. I need to learn how to use them.

So you first use compressor and then cinema tools in that order, or can you just use cinema tools?

I'd rather have the flexibility to choose my speed in post also. Actually, I can. I can import a shot recorded at 60fps and either remove duplicate frames or use the frame rate converter. I guess i need to know if compressor and cimema tools makes doing that even better quality.

Thanks!

You don't need Compressor for this, I mentioned Compressor because I used to use it BEFORE I bought the HVX.

I don't know about the Frame Rate Converter - but if it ditches the audio, try duping the Media file, then use Finder to open Cinema Tools;
Open With > Cinema Tools.

Then close the Database window and Click "Conform". CT will then show you the existing rate and you can choose what to conform to: It conforms virtually instantly.

Andy - do you always shoot at 50fps and just use CT to adjust your speeds in post? I acutally like your workflow. Being able to decide what speed or frame rate you play back your shots in post gives you a lot more latitude with your footage.

Thanks!

That's absolutely right, William, on the current project, I'm shooting everything at 50fps - but you must remember that it takes up much more drive (or P2) space than shooting 720pN.

My justification is that you're getting many times the footage really because of the flexibility it allows.

But there's more!
Take this example:
When I was working in DV, I read a Patrick Sheffield article about using Compressor to increase the Frame Rate to 50fps, then use CT to Conform it to 25 for 50% Speed. This gave FAR smoother Slo-Mo than FCP could.

So now I (we) have the HVX and we can shoot at 50 (or 60) fps . . .
why not take this a stage further? Use Compressor to change the frame rate to 100 (or 120) fps - this is only doubling it (as it was when I used it to double DV to 50 - if you follow).

Now we have 100fps - we can Conform it with CT to 25fps - and we have QUARTER SPEED! It's not perfect - but it's durn good!

Of course, you can use Compressor to make the Frame Rate whatever you want - so there are endless variations on the speeds you can get between the HVX, Compressor and Cinema Tools - if you can work the figures out (I have great difficulty with this side of it)!

It's not for everyone but I'm shooting loads of Random Action and I never know at the time, what speed I'd like the finished clip to play at. This way, I get to choose AND retain very high quality.

There are Shutter Speed considerations, though - read Barry Green's post on this topic:
