Transcode 7D footage before or after overcranking in cinema tools?

[Curious Turtle]

What application are you using to do the transcode to ProRes? If you’re using Compressor then you can just set it up to do both at the same time.

Set the codec up to ProRes and the framerate to 25 in the encoder pane. Then in the Frame Controls pane make sure that the Set Duration has “So source frames play at 25fps”.

If memory serves, that should do you.

Ben

Thank you Ben, I appreciate the prompt reply.

I played around with the footage for a few hours today and I think I have the process wired. I will try your way and see how that goes also.

Thanks again,

Riley

Here’s my workflow for 7d Slow motion..

1) Transcode h.264 to prores using mpeg streamclip
2) Conform Prores footage using Cinema Tools
3) Edit conformed video in Final Cut

Here’s a sample video of some slow motion video using the above method.

I did this little ‘project’ a different way just to see how it would go. It was pretty painless.

First, I conformed in cinema tool on the h264 footage. Loaded it all in to Final Cut. Then, I used media manager to recompress to a new project. I haven’t used mpeg streamclip, but this process was pretty darn simple – but it did take about 2 hours to transcode all the clips….

Here are the results.

Sorry for a basic question (new to all this stuff),

Was this shot 25p (or 24p)?

What does Cinema Tools do? Is this for Slow Mo?

I have stayed away from 25p (Australia) because everything looks jittery. Is this what Cinema Tools gets rid of?

I use 25p as I live in Australia.

It is my humble opinion that 24p is somewhat more desirable as it is closest to the frame rate of film.

Cinema tools is used to conform 50p/60p footage into live slow motion if that makes sense.

When you shoot 50p footage on a DSLR you need to use a program such as cinema tools to do this.

[John Davidson]

Was this shot 25p (or 24p)?
The slow motion footage was shot at 720/60p. The regular speed footage was shot at 1080/24p.

What does Cinema Tools do? Is this for Slow Mo?
Yes, If you notice, shooting 720/60p, footage looks like ‘video’ because the footage is overcranked.
If you shoot 10 seconds of footage at 24p, you end up with roughly 240 frames of footage, which is 24 frames per second (the nice looking film frame rate). Shooting at 60p creates 600 frames of this exact same 10 seconds of footage. If you don’t touch it, you get a video look at regular speed. Cinema Tools changes the frame rate that these 60p clips play back to 24p, resulting in 600 frames played out at 24 frames per second, turning that 10 seconds of footage into 25 seconds of glorious, smooth, slow motion.

You could also probably conform this 60p footage to 25p, I live in America though, and since every thing we do is right and perfect, I can’t confirm how that process would work :). Lol!

Is there a difference between conforming 50p to 24 or 25p in Cinema Tools and just changing the clips’ speed on FCP timeline? Tx!

[Curious Turtle]

If you use Cinema Tools to change the frame rate there is no interpolation between the frames. It just plays those frames that were shot at 60fps at 25fps (or your chosen frame rate). You get sharp frames the way that they were shot, they’re just playing back at a different speed.

Changing the clip’s speed in FCP forces a render and creates interpolation between frames. So FCP is making up new pixels instead of playing the original back at the new frame rate.

Hope that makes sense,
Ben

And what if I disable frame blending in the Clip Speed panel (cmd-j)? I should get the same results as when conforming in Cinema Tools, shouldn’t I?
