A few basic video questions.

Educating myself about using dslr to shoot video. I'm comfortable with shooting stills and have been educating myself about video. Haven't tried one yet. Still need some equipment. Just a few questions come to mind.

Should lens Image stabilization be on or off when camera is on tripod while videoing. I've heard both suggestions on the videos. Off, is recommended when shooting stills, otherwise damage to the lens could occur.

Is cropping possible/typical in post processing. I typically have to crop my wildlife stills.

I know I'll need lots of storage. What is typical file size for 1 minute of video shot at 24fps, 1080p shooting raw.

How many minutes of shooting can you get out of your batteries, roughly.

thanks.

Hi Larry! I've only recently started to do video.

Your owner manual is your friend on this, as well as Google. Each DSLR is different on what it does in terms of image stabilization et al.

IS. If IS works when doing video, it should probably be off while on a tripod for video recording. IS in the 5DM3 doesn't work for video. IS in the G16 (compact) works in video, but I don't use it on a tripod.

Cropping. I use an iMac, and specifically use iMovie for video editing. I have cropped 1080p video with iMovie. Cropping works, but you're really simply expanding pixels. If you were shooting 4K video and cropping that, you could probably get a decent 1080p video in the end. That's theory however.

File Size. It depends on your camera and compression mode, if you can choose that. The 5DM3 has two compression modes, resulting in very different file sizes for the same length video. Also, some DSLRs don't have 24fps; they have 30 or 60fps. The 5DM3 at 1080p, 30fps, higher quality compression (larger files with more info for editing) creates about 1GB/min.

RAW. You don't shoot raw in video. You shoot mpeg. Also, you need to understand that if you shoot "manual", your shutter speed should be roughly 1/(2xFPS rate)s. If you're shooting 30fps, your shutter speed should be 1/(2x30)s or 1/60s. Otherwise it goes funky.

Battery Life. This depends on your camera, frame rate, et al. What I've shot with the 5DM3 hasn't been too long, up to 20min, doing 1080p, 30fps, higher quality compression (larger files with more info for better editing). Battery life for the 5DM3 has never been an issue. The G16, 1080p, 30fps (no compression choices) goes for about an hour of video.

Have fun with video! It *is* different from still photography. Shoot some video. Try some things. If you want a good book on creating video, there's one I got and like. "How To Shoot Video That Doesn't Suck" by Steve Stockman is about content, not about camera settings. It's very good.

Hope this helps!

All modern IS systems today can identify when they are on tripods and operate without damage. IS is extremely valuable for DSLR video unless you're really developed professional camera handling skills, even using a tripod, even with wide-angle lenses.

Yes it is possible.

That's going to depend on the camera model and a lot of other factors. There are a lot of definitions of what "RAW" means in video. Some mean "uncompressed," some mean "unprocessed," some mean both, some mean 4K, all to various degrees. Among DSLRs, a large number Nikons produce what they call "RAW." Canon's require Magic Lantern software to produce RAW as still photographers understand it, and just as with still RAW, it requires an additional processing step (with third-party software) to get it to a format you can then edit.

I've been on the transition from still to video for just at a year now, and I'm not giving any thought right now to going RAW. There is 'way too much to learn about video shooting, editing, and bleeding audio.

But you can expect to need fast cards no less than 64gb for that use, and battery grips.

On RAW... Ah, I didn't know that. I learned something new. Thank you! I stand corrected.

Good stuff. Thanks.
