I’ve yet to find a good DIY source for building rails. I am a big fan of DIY equipment – I’ve built lights, dollies, rigs, stabilizers, etc. For me, it’s fun making something you can use. If I could afford the spendier stuff, I would get them. I picked up the Killer Camera Rigs That You Can Build book and have built a couple rigs, too.
I guess I just need to know if there is a standard size/configuration for rails…?

Jeff, it seems there is a bit of hunt and peck involved. I think the difference is that OSX sees the drive and the partition as separate (guessing here). I delete some files from my CF card while plugged into a CF reader, then empty trash securely. Opened the second instance of my CF (based on the size of 4110MB – 4GB CF card) and it seemed to find it, but I didn’t go through the whole process. I’m not a huge fan of terminal window apps, either, but if it recovers a vital file, I’m game. I got the file system wrong, too, at first. Forgot it was FAT for Canon. I think the 7D is FAT32, but don’t quote me on it – could be FAT16. If you figure the rest out, I’m interested to know what happens – I’m sure I will run into this again. Beyond that, I’m going to remember to run Time Machine before any large file deletions. 🙂

I started looking into the Photorec software more. I’ve now downloaded it and I’m having a try at “recovering” files I’ve deliberately deleted. Seems to work pretty well recovering image files from my Rebel xt CF card. Since it’s specific to media files (and media cards), I think it’s your best bet right now.

I wonder if anyone knows: what’s the final image difference between the 7D and the t2i? Specs are one thing, but if the 7D is really worth the extra $900 or the 5D…you get the idea, is it that much worth the extra expenditure for that much better quality (like the difference between a consumer camcorder and a pro-level camera or between one pro-level and another)?

Sounds like rolling shutter. No sudden movements with the camera or you will get weird artifacts (may not be the right word). Can you post the offending footage?

Well, that camera uses DCF 2.0 (from the manual) – so the single picture is just a sort of preview built into the file. The final file is some kind of MP4 AVC, BUT the file type should still be MOV. Here’s a question: can you play the video on the camera with the card in (I’m assuming you mean the file is still on the card anyhow)? If so, the file is probably just fine and you should be able to re-transfer the file.
If you have Time Machine, it may be able to help, but I’m guessing you don’t use it – frankly I’ve not had to use TM for that specific purpose (knock on wood).
I found another thread elsewhere on this that mentions 7D file recovery (the big one dated Aug 20, 2009 at the very bottom). He mentions software at the end called PhotoRec (freeware: https://www.cgsecurity.org/wiki/PhotoRec ) which saved pix and movies. Talks a lot about bad SD cards, too.

Hi there, I don’t usually use the audio from either the 7D or 5D as it auto-adjusts the gain – making for weird audio. I’ve read about issues with the audio working prior to converting to prores and then not working when brought into FCP. How off is the sync? Is it a frame or 2 and a nudge will fix it or is it something else?
Do you have audio from an external source? I use the Zoom H4 for audio, but I have issues with that sound as well over long periods (I’m reading this is fixed with the H4n). I think this is actually a bug with the Zoom, but when I use the external audio and sync with 24P footage from 7D, using the 7D’s captured audio as reference (I also use a slate), I don’t have issues for short clips.
Since others are seeing the problem, it could be a few factors: the 24P footage may not be exactly 23.976 (7D problem?) – don’t pulldown the footage, treat it like plain 24p video unless you are planning to convert to film; the audio, when demuxed (?), may no longer sync up which could be the camera or the conversion or the file format – 7D uses linear PCM (at 48khz at ??? bitrate) which should be fine, but there you go. Problem could be with FCP, but I’m inclined to think it’s the files and not the app (mostly since I seldom have issues with all kinds of weird audio/video in FCP). Try delinking the audio from the video in FCP, move the audio to soundtrack or cubase or another audio app and make sure it’s all good and get the audio settings. Make sure those settings match with what FCP is expecting. In the future, I suggest using external audio from a Zoom or another external audio mixer/recorder device with XLR inputs for better control (just saw the new H16 which looks really neat for $400, but the H4n is now about $300).
There is a preset from Canon for the 5D which I think works for the 7D, though 5D still has only 24 and 30 fps (NOT 24P/30P)

Well, MPEG Streamclip is not as robust as Compressor. I also use MPS for ripping DVD captures and such. I don’t really think you can compare the 2 inasmuch as they are both markedly different apps designed for different purposes. I still use it when I have a ton of video to convert to prores or another format and I don’t need to alter the frame rate. It’s usually when I have DSLR footage at 24 or 30 fps that I hit problems and I have to use Compressor.
On the other hand, if anyone is familiar with both MPEG Streamclip and Compressor on a more technical level, I would love to hear pros and cons. If you haven’t seen it, info is at https://www.squared5.com/ – Compressor is apple.com of course.

If you haven’t done so already, make sure you grab and use an 18% grey card. Don’t kill your budget buying one, but get a good one you can use many, many times. I’m sure you’ve white balanced, but grey-balancing is vital, too. Here’s a good tutorial:

He provides a link to a decent little 12″ one and offers other things you can use to balance your video.

Hey there, not sure if this will help and I’ve not used Avid, BUT in FCP, I tell it to use anamorphic NTSC and it seems to work fine – tested DVD on my friend’s very large 16:9 TV on both DVD and Blueray players as well as my 4:3 TVs. I know if I don’t tell it to use anamorphic, I get the same problem you have described here. FCP is supposed to auto-detect this, but it doesn’t seem to auto-detect real well (or I’m picking the wrong setting). Most new DVD and bluray players automatically letterbox or stretch the video once you’ve output to DVD.
