[Will Aldersley] “Yes possibly I changed battery without stopping record.”

This is the likely culprit. Try to never, ever, ever, ever, ever, ever, ever, ever, ever, ever do this again! 🙂

Reason being is that when you hit “stop” the camera is actually closing out the file and saving the last bit of code needed to make it a readable Quicktime .mov format. When you interrupt this process you sabotage the file. It’d be like pulling your pizza out of the oven before letting it cook entirely. So, in the future, do yourself a favor and let your pizza cook fully….always press “stop” and then power down the camera using the on/off switch.

Gotcha. Yep, we decided to roll our 5D3 firmware back to 1.1.3 so we could use ML. I’m glad to hear that they have a working 1.2.3 compatible ML out. I’ll probably give it a few months and then give it a go! 🙂

Let me know if you encounter any hiccups!

WIll – what do you mean by: “when you export it?” Since Canon shoots in a Quicktime format (.mov files) all you have to do is drag and drop that to your computer (Mac or PC) for playback. If you’re truly “exporting” something then we need to look at what you’re doing in that process since you’re converting the file to another format….

Or you have a corrupted .mov file on your hands. Did you happen to turn off the camera before pressing stop on your video recording? If so, you can use something like VLC player to open it and convert. See also this thread from a few years ago for other options:

Nope. That’s a limitation of the camera itself- https://www.usa.canon.com/cusa/professional/products/professional_cameras/cinema_eos_cameras/eos_c100#Specifications

Look under Recording/Codec and you’ll note the only file system listed in FAT32. With that said, how you ingest that footage could solve your problem. Programs like Adobe Prelude/Premiere Pro or Canon’s own whatever shipped with your C100 software will parse the card structure and display one seamless file to the end user. So even though your 60 minute clip is comprised of several 12 minute 2GB files, you’ll only see the 1 whole 60 minute clip.

FCPX may do this as well, but it’s been a while since I’ve been in that world. I’m pretty sure Avid doesn’t have a solution for this yet.

What camera did you shot on?

DAT files are not typically used for video storage (though there are exceptions). Most cameras shoot MOV, MTS, etc. But a quick Google search will net you several DAT to AVI converters to try out.

And it’s stable? I’ve always been afraid of the nightly releases…

I think I’m running a ML version from a few months ago as it’s proven very reliable. I’ve learned about being an early adopter the hard way! 😉

Sounds like whatever you shot on formats the cards in FAT32 format. This is a limitation of that file system – it can’t store a file larger than 2GB, so it breaks the file at the point.

You shouldn’t have any drops in between breaks, if the camera did it’s job correctly.

[stan welks] “If I leave the CS/CC world, will the metadata be read by other applications?”

No. Adobe’s metadata information is proprietary to them. Anything buried within the clip itself will transfer from app to app. But information created in Adobe’s universe stays in that universe (same as any other vendor).

[stan welks] “Any idea if the new AVCHD file that Prelude creates when transferring files can be read by other programs, such as FCPX?”

Yes, AVCHD files will go into FCPX. Typically most X users will transcode that to ProRes(LT) for smoother editing, color grading, etc. A process that FCPX can do “in the background” while you work. For more information on that check out the FCPX forums here on the Cow, as they’ll have firsthand knowledge than some of us Adobe people. 🙂

[stan welks] “Where is the metadata added to the files used? Lightroom?”

It depends on your workflow. Some use it for offline/online, others use it as they pass the footage down to colorists, others use it for review, etc. Metadata is just information about your footage, and that can be any number of things – time of day, f/stop, interview questions, etc. Your workflow and needs would determine what data you’d want to create and input.

[stan welks] “I would very much like to find a way to tag all of my large videos for easy accessibility later.”

This sounds like your talking about a MAM program – Media Asset Management. Prelude and Premiere are not MAM’s. For that type of solution you’d need to look at eMAM, CatDV, Cantemo, etc.

[stan welks] “What did you mean by “data copy””
If you’re worried about getting data off your SD/CF cards there are plenty of programs that can do that for you – Shotput Pro, BulletProof, etc. Now Prelude does do this too. I’m trying to say you need to switch just letting you know about other options out there.

[stan welks] “Prelude and into a new AVCHD file, is it safe to delete the original AVCHD folder? Is that the idea of what Prelude does?”
Prelude is a pre-editing and logging tool. You may want to look around the web and watch some tutorials for Prelude and how it’s used. Adobe has some great tools and tutorials to help you get familiar with Prelude: https://tv.adobe.com/product/prelude/

Or a simple Google search with unearth mountains of data for you to enjoy: https://lmgtfy.com/?q=adobe+tv+prelude+cs6

Hope that helps!

1.) depends on how you’ve setup Prelude to ingest. It can transcode your footage to a different format if you desire.
2.) others can correct me, but I thought that Prelude will “stitch” together multiple files into one when ingesting certain formats that span multiple files. So if you’ve shot a 2 hour event and there’s 5 files from the camera Prelude will create just 1. I’m assuming this based off my experience with MXF files from the C300 where it does something similar.
3.) yes use PPro for editing. Prelude allows you to do rough editing if you want. In fact, unless you’re adding metadata to your files, transcoding footage, or wanting to rough cuts you can probably just to into PPro straight away and start editing. If you’re worried about data copy there’s plenty of programs on the market that can facilitate that transfer.
