I'm going to be using a C100 Mark II for an upcoming project. I need a little bit of slow motion. The entire project will be in a 24P timeline. It looks like I have three options to shoot 60P:

1 - AVCHD 60P
2 - MP4 60P
3 - MP4 special slow & fast setting

I'd like to stay with MP4 files. Is there any benefit to shooting the slow & fast setting? Or would dropping the 60P on the timeline and selecting automatic speed be better?

Thanks for any help with this,

James

I don't have any experience with a C100, but on most cameras the slow and fast motion settings are no different quality wise, they just slow the video down for you, and don't recored audio.

I'd just shoot 60p and slow it down in FCPX, that way if I ended up wanting to use the shot at normal speed, I could.

I'm editing C100 video now, and the AVCHD is better quality than the MP4. Shoot 60p, edit in a 24p timeline.

by standards, AVCHD allows a max. bit-rate of 28mbps. And in its beginning was meant for 25/30fps
a mp4 allows 'any', higher bit-rates... your C100 Mk II offers 35 mbps...

so, theoretically, the mp4-settings are a 'better' ......

@mobiletaylor you might consider recording the uncompressed HDMI output if you have an external recorder such as BMD Video Assist, Shogun or Atomos recorders. Outstanding quality but very large files.

I don't know about theory, but we tested, and we think the AVCHD looks nicer. Just our first hand experience.

for sure you do, Ben :lol: - bitrate defines quality, 35 beats 28... in theory.
(if camera uses the same h264 implementation in mp4 and AVCHD)

But reality-check always beats ANY theory.... we're in the same boat with that.
I'm no pixelpeeper, by far not! :woohoo:

My final projects will be 720p for the internet. So I want to keep the files small. I've tried both AVCHD and MP4 on my system and the MP4's seem to work a little smoother. I had to convert the AVCHD files with ClipWrap to get usable results. I don't want to go through that process, so 60p MP4 should work jus fine.

Thanks again everyone!

Actually, FCPX will ingest C100 AVCHD just fine. I've got 7 TB of the stuff I'm working with. No clue why you wasted time with ClipWrap.

The files will ingest just fine, but my system always slows by a noticeable amount. It's been an ongoing problem for me. I've spent the last two years working with AVCHD files from sony handicams. Usually 5 to 6 angle mulitcam clips. Never had good luck with them. As soon as I run them through ClipWrap everything is smooth. I think it's just my setup. I've been desperately wanting to upgrade to a new 15 MacBook Pro with graphics card, but intel hasn't been cooperating! Hopefully soon!!!

I'm using a C100 II as well and tend to shoot 1080P 60 and edit in a 29.97 timeline. Even though I'm not a devout pixel peeper, being curious because of seeing so many comments about which is better I've been looking at comparisons as well as trying my own. Here's one I foundhttps://vimeo.com/119822152

I haven't been able to see any difference between AVCHD and MP4 but do find the MP4 easier to work with so that's what I've been doing lately.
