Hey there,
Yeah, I generally have to convert this 30fps to 29.97 using Compressor now – MPEG Streamclip doesn’t seem to want to convert the frame rate.
Also, Canon is working on or has developed a firmware update that will supposedly update the 5D MKII to do 24p, 25p, and 60p (@720p). A friend told me the reason the cameras do not drop frames is because they were designed to allow photographers to shoot long streams of continuous images for photography (they can just pick the frame they want from the video).

I’m thinking the 7D and 5D footage are pretty much the same in terms of overall quality, MPEG4 (I think), and h.264. I know the 5D has a bigger sensor than the 7D and doesn’t have a magnification factor, but since the final comes to a relatively small 1080×1980, I’m pretty sure it’s a nominal difference.
I’m setting up a project where my people will have a 5D and a 7D (as well as another camera) for the production so I’ll be able to check the differences. Now I’ll need to figure out how to sync 2 canons together. Shouldn’t be too bad, but there’s no timecode on these, I don’t think.

okay, so I’m playing with Compressor now:
In Compressor, I add my first file (actually a wide, est shot from the 5D), then, under Settings, go to Apple > Other Workflows > Advanced Format Conversions > Apple Codecs > Apple ProRes 422 for Progressive material (High Quality). Drag this to your open file above in Compressor.
There’s another setting for interlaced versus progressive, but we shot the footage at 30P so I’ll use that.
Now, make some custom changes:
Make sure you have your codec with your file selected.
Go to the Inspector, look at the Summary – all is well for me by default except the frame rate is at 30fps and I’ll be editing this as 29.97. Click the Encoder button, click on Settings by Video, change the frame rate to whatever you want (29.97 in my case). By default, this area has “Enable 4:4:4 chroma filtering” checked. I’m leaving it. Anyone know if this is particularly detrimental to the final product? click Ok.
That’s it for me, but I also saved this as “Convert 5D to ProRes 422 HQ.”
MPEG Streamclip will batch an entire folder, but it doesn’t want to change the frame rate so there are +&-.

Well, I don’t have multiple cameras to play with and the HMC150 manual specifies setup for a Master/Slave multi-cam deal, but nothing for inserting an external TC device. The 702 seems a lot more versatile than the HMC150, though. Looks like you may need to convert cables to make the setup work. I would just get an RCA to AES/SPDIF cable and give it a shot. I’m betting something like this just takes some practice that manuals just won’t cover specific applications. Do you already have the camera and recorder? I’m thinking you would set the recorder as master, then the cameras as slaves. I’m interested to know how this turns out!

Thanks for getting back! You know, I’ve only ever used Compressor for compressing and the 5D/7D footage already seems pretty compressed. Do you mind saying what settings you are using? Also, do you use any FCP custom presets or just the ProRes files in an existing preset?
Thanks for the feedback!
BTW: saw your trailer for inconvenience. Looks like fun!

Yes, it’s basically that a DSLR is still scanning the sensor from top to bottom (or bottom to top, I don’t remember which) – the result is a distortion of objects coming in from the side because one part moves there before the sensor is done scanning – making for a diagonal, distorted look OR you will see some strobing. I try fixing by using a faster shutter and/or a wider lens. Boris has a plug-in that will fix the distortion, too.
