How long 7d record




















But why do you need the 24p film look with shallow DoF of a guy at a lectern for an hour straight with no cutaways? No need to worry too much about focus or filesize limitations. Thanks guys for all your input. You raised a number of very good issues. First one of course, it's boring to have one shot for an hour anyway that had occurred to me too hence the idea of overlaying the speech with illustrative footage or stills , but the idea of having a second camera with shots of the audience and close-ups should really liven everything up.

Spending extra money on even a cheap HD cam do they shoot long continuously anyway? I may just equip myself with a stop watch and rely on cheap family member labor to stay guard at one camera, while using the 7D placed at the side of the stage collecting shots from the audience and close ups of the speaker.

Then everything should just be down to Premier Pro. The file limitation still bugs me though from a purely creative point of view. What about not being able to do time lapse? I don't mean the speaker of course. I hope this threat will attract further lively discussion. Would be great if Canon's attention could be drawn to this flaw, because that definitely is a BIG one. The battery would probably last an hour, but, It may last longer depending on it's age. For 32GB, you're looking at around 96 minutes of full HD x footage.

Isnt the XM1 a aspect ratio video camera? That would be a total deal breaker for any current day video capture. Even SD is displayed in , never in Are you using a wireless mic on the speaker? If you cant hear him clearly and without room noise, the video is useless.

Without a continuous video capture, you are going to have breaks obviously. Usually you edit a video during editing, not shooting. You could use a digital audio recorder to capture the audio off your wireless mic, but then you would have to sync and timeshift the audio in post.

This is a project for a dedicated video camera. Depending on the clients expectations and the importance of the event, the client may want a video professional for this.

The speaker uses a clipon microphone with a transmitter conneted to a sound system, not at all sure how this will affect the sound quality. Your digital portable audio recorder suggestion could be the answer. I have no idea whether is will pick up the sound from the speaker or the sound system and whether this could be a problem.

Agree, a well equipped pro would be the answer, but the "client" is a friend with only a favor as a budget. It looks increasingly like the XM1 may provided the simplest and probably the only solution, with its stereo microphone simply picking up the sound from the sound system.

Shame though having to forgo the HD quality. Maybe someday Canon will address the 4GB issue, but you gotta remember that it's a still camera with video, not a video camera. They just don't have the motivation to implement file spanning. Also, I believe in the EU, additional taxes are collected on devices being able to capture 30 minutes or more of video.

There are a lot of low-end video cameras with a 29 minute limit. As for time lapse, you might be better off using stills. You should also remember that while there may be tax implications in a few parts of the world, the FAT32 file system used for memory cards is also a barrier to this 4GB limit. Sure, on could suggest that it simply stop itself and restart however I am not sure how reasonably that could be accomplished and what the end result would be in post would you miss a second or so of the recording?

Since the XM1 is , that is a great option. You have it covered. These are caused because the image data is captured and then read off the chip sequentially by rows, rather being captured all at once. The effect on moving objects is similar to that of a focal plane shutter in an SLR, but more pronounced, because the video frame is read out much more slowly than the slit of a focal plane shutter moves across the sensor.

For a camera that scans video frames vertically as all do that we're aware of , rolling shutter artifacts will be most noticeable for subjects that are moving rapidly side to side, or when the camera itself is being panned horizontally. Verticals in the scene will appear tilted to the right or left, depending on the direction of camera motion.

As an example, consider the case of a camera being panned from left to right, with a flagpole or other vertical object in the middle of the scene when recording for a particular frame begins: If the top of the object was centered horizontally when the first line of the video frame is acquired, by the time the last line of the frame has been captured, the bottom of the object will have shifted to somewhere left of center: As a result, the vertical object would appear to be leaning to the right.

The visual impact of rolling shutter artifacts on the Canon EOS 7D seemed a bit less noticeable than in some other recent digital SLRs, but as noted, it's still a factor. A typical computer these days has little trouble dealing with still images, but high-definition video can be another matter.

Depending on the file format involved, it can take a pretty beefy computer to handle HD-resolution video playback without stuttering or dropping frames. The net result is that you'll want a relatively recent and powerful computer to play full-res high-def video files from the EOS 7D on your computer. At lower resolutions, the requirements will be more modest. We found that we could run the 7D's video acceptably at half size on an older G5 Power Mac with dual 2.

Both terminals cannot be used simultaneously. Overall, the Canon EOS 7D seems to be a great video machine, albeit still without continuous autofocus capability during movie recording. It should be an excellent, cheaper and hopefully more available option to the EOS-5D for people looking for high definition video from a digital SLR, particularly one with a Canon lens mount.

Note: The above sample videos were taken with a preproduction unit, however tests of our production units showed no difference. Canon 7D Video Tweet Share. Unlike some competitors, the Canon 7D's highest resolution does conform to the HD dimensional and frame rate specs both 24 fps and 30 fps , so it's usable for recording high-detail video for display on an HDTV. When I first looked at this shot, I thought it was back-focused, but on further scrutiny, decided that the issue is simply that Charlotte and Marti both have much softer detail that gets stepped on more by the H.

It'll depend a lot on the screen size of your TV of course, but the good news is that this kind of softness isn't nearly as apparent during playback than it is when pixel-peeping a crop from a frame-grab. This crop is also from 1, x 1, resolution video, but this time at 30fps.

Sometimes I can convince myself I'm seeing a little difference, but suspect it's just because I think there should be one. If there is one, it seems it'd take a pretty well-controlled lab test to smoke it out, vs these fairly casual samples.

One thought, though: Could camera shake play a role here? Hard to argue with the crop above, though: When specifically looking for detail in video images, we need to be looking at shots captured while on a tripod. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. Is there a way to make the camera split the video and continue recording in a new file?

It's not possible with standard firmware, not ideal with Magic Lantern either. From the ML wikipage:. To record continuously for more than 30 minutes, you need to use a HDMI recorder.

Enable the Clear Overlays feature to hide the focus box and the bars, and make the half-shutter button sticky to prevent the camera from turning off LiveView after 30 minutes. Technically, there's no 12 minute limit. There's a 30 minute limit and a 4 GB limit, whichever comes first. With default bitrate settings, the 4 GB limit is reached after around 12 minutes more or less.

No change to resolution, frame rate or length of recording. If I'm shooting full HD on my 7D, I only get 11 or 12 minutes of video for stage shows outside is slightly longer. Looking at the files, they're all 4GB. I can hit the 30 minute length only if I drop to a lower rez.

PuppyDigs , Dec 17, I'm not sure about this but I think some DSLRs automatically start up a new file when the 4GB limit is hit, so you do lose a couple of seconds of the action but you don't have to manually start recording again.

I'm not sure how much this helps though. The 30 minute limit is actually artificial in that anything that records video for more than 29min and It's not, as is sometimes suggested, to prevent overheating. If the camera overheats it will shut itself down anyway. Does anyone know if the 7D mark 2 has a longer limit?
