The squares in a row on the right represent the buffer memory of your camera. When you are recording video the data goes roughly as follows: Sensor -> Buffer memory -> Memory card When the last square turns red it means the buffer is full. This is caused by the fact that the buffer memory could not move it's contents to the memory card fast enough. ...

On DSLRs, a fast shutter can actually be better. DSLRs scan the image to sample rather than capturing the whole frame at once. This is why you get a distortion when you do a rapid pan. A faster shutter will result in stopping motion more clearly (less motion blur), which can seem a little harsher than the softness of film, but a sharper image may be ...

I disagree with the above answers. Our visual culture and the century of cinema has dictated that we evaluate a 180 degree shutter as "normal", because that is how film cameras have worked almost forever, and that is how most scenes in every movie are shot. 180 degree shutter is the same as 1 over twice the frame rate, or 1/48 for 24fps. If there is ...

Some things to be aware of when shooting video (this applies to most DSLRs): Rolling Shutter Because of the way the 550d records each frame you can end up with slanted video when combined with fast motion. This is because the camera recordes each frame line by line, so each line is recorded at a slightly different time causing a warped effect. Its not a ...

While reviewing the Instruction Manual for the Canon 2Ti EOS 550 on page 127 you will find information on how to manually set the shutter time. Here is the pdf download for the manual: http://gdlp01.c-wss.com/gds/9/0300003169/01/eosrt2i-eos550d-im-en.pdf There is wide range of 1/4000 to 1/30 of a second to work with depending on your frame rate. For 50 fps ...

So after 8 hours of research, trial and error, I found a successful workflow for .mov footage from my Canon EOS Rebel T3i. The first part is that you can't import .mov "Apple / H264" files with Lightworks without purchasing the "Pro" version. The pro version costs $60 per year (which is actually a good price for what you get). So I bought that and was ...

In almost all digital video cameras there's no physical shutter, just a circuit that limits the exposure time. As long as that time allows the entire sensor to be illuminated and scanned, you should see no degradation of any individual frame. In this sense, as long as the minimum is met, there should be no visible difference between a fast shutter and an ND. ...

The default video files made by most Canon DSLRs is an H264 video file in an MOV container. Decoding high definition video at the data rates that most Canon cameras use is intensive for both memory, disk and CPU unless you have a dedicated decoder chip. Your iPod Touch uses flash storage (which is fast) and has H264 decoding capability to make it run ...

Should be mentioned that the 600D isn't exactly the best DSLR for video out there. The artifacts that you are experiencing in your footage are the result of high compression. Check your video settings if you can increase the bitrate or choose a different codec other than h.264/AVC if Canon offers one by now for their DSLRs. This thread might be interesting ...

Certainly using RAW on ML will help. With 14 bit color, your noise reduction options are a lot more advanced. Traditional noise reduction that you are used to from photos can be used with video as well using either color grading software or editing software. (With RAW video, it would be in the color grading software before mixing down to processed clips.) ...

I've done this to combine the video onboard an aircraft with the video shot from the ground, and if both of my cameras were good quality, it worked pretty well. I tried to merge the videos using time codes, but that doesn't work even though they both had GPS- things with identical time-codes just weren't happening at the same time. So, here's what I do now.....

I hate to burst your bubble, but if you are expecting video to be a similar level of intrusiveness to photography, you are almost certainly mistaken. Video is a much more work intensive process as it requires constant attention to make sure you are getting smooth usable shots instead of the occasional random thought that "I'd like a photo of this." It is ...

You should consider other options than Nikon/Canon. Even if they have proven DSLR can do really good video, thanks to 5D Mark II/III and Magic Lantern, they do not compete well against Panasonic and Sony. If you compare 5D Mark III against a Sony A7S, you're going to have a much better video quality on A7S, thanks to its far superior sensor. Much higher ...

Welcome to Video Production Stack Exchange! Bad news first- Unfortunately, you are stuck with the in-camera mic with the T6. The T6i has a microphone jack for mounting an external microphone. If you want to mount an external mic to a Canon Rebel T6 body and record that audio stream to the same SD card, that's really your only option. However Can you ...

It is likely not possible to change in camera. For power and efficiency reasons, cameras generally use dedicated encoder hardware to encode the video in real time (this is why your camera can encode h.264 video live, but when you try to encode it on your PC, it takes longer, even though your computer is far FAR more powerful.) The caveat of this is that ...

Your theory is correct, video is much less demanding of resolution than stills (1080p HD is only 2 megapixels). However you'll never get a truly sharp video image out of a Canon DSLR due to the strange interpolation/line-skipping that is used to produce a video frame from the full image sensor resolution, the result is always a lot softer than you would get ...

The usual tool recommended for this is JES Deinterlacer, which apparently has an adaptive method of finding and removing the 'smear' frames. I haven't used it myself. The reason this is an issue is that the field cadence used for PF24 is (stupidly, IMO) different from the typical telecine cadence, which is what most 'inverse telecine' algos detect and ...

The CineStyle picture style provides you with a flat, desaturated image: providing the best dynamic range of any of the picture styles for Canon DSLRs. Technicolor provide you with a file that you can apparently import into your editing software to help you grade your footage. However, I never figured out how to use it and frankly, I don't think one needs to....

Ok, I've found the problem. I have tested with another lens (Sigma DG 70-300 f/4 - 5.6 Macro), and the result is much much better than with default lens. But I am not able to explain this.


3

Yes, there is a lot you are missing. The 24-70 has substantially better transmittance (more light makes it through the lens), slightly better sharpness, significantly less chromatic aberration, 2 more diaphragm blades (better, more round bokeh), full time manual focus (can auto-focus at the start of a shot but still adjust after starting shooting). ...

No, the D750 is not a good alternative for an avid videographer, at least not if you want the advantages Magic Lantern offers. ML isn't available for Nikon. The reason has nothing to do with the technical advantages of either platform, you can get models of camera that are fairly close in that regard. The problem is that Nikon does not have anything ...

Firstly, that camera has a 29 minute 59 second recording limit. If your speaker goes for longer than this it may not be suitable. Apparently this is due to some countries charging higher import duties for video cameras, but if it records less than 30 minutes it's not classed as a video camera. Yeah, I know. The DSLR will probably cope better with low light ...

If the stills look sharp and detailed, then the sensor and optics are not to blame. I would blame the encoder and whatever sacrifices Canon made for the video mode. The 80d has the same Digic 6 processor as the older and cheaper models like the T6i. I have an older model T4i, and it is very low-res in 1080p mode, while in 720p mode it is chock full of ...

just figured it out woth magic lantern. You wanna turn on frame rate override, and change thr timing clock from its perfect number to something slightly above or below the usual 4200 or whatever it is. I got a true frame rate of 26.007, and a flicker free video of a lcd screen. Bam!

The link on the video says they used magic lantern which is alternate firmware update that is open source for the t2i and other canon bodies. I can only say that canon will not support it, it can void your warrenty, and overheat and cause all sorts of shut down problems. Having said that, this is how they were able to adjust the shutter setting slower. I ...

It should be. You might end up with impedance mismatches that have to be dealt with, so it might take a few other (relatively cheap) steps to get there (devices called pads, which bring down the level), but it should work. The quality might not be quite as good though.

Depending on how much you are looking to slow down. Interpret as 50fps, and then once in your timeline, say it is a 25fps timeline. Then you can stretch the footage using time remapping, then you can turn on frame blending to the solid line...this will be good in most instances up to about 25% speed of original... Less than that the same, 25fps timeline, ...

The reasons for an automatic stop are either reaching the 30 minute limit (thank you European Union video camera tax that ends up impacting what's available to most of the rest of the world), hitting the 4gb file limit (file system limit for the OS on the camera), the sensor is overheating (high usage + temperature) or the buffer is being used up (memory ...

You are correct. You're shooting at a much lower resolution on video than stills, and so your effective circles of confusion are much bigger. So you can get away with glass that a decent stills photographer wouldn't touch. This is speaking from experience at work where I share DSLR equipment with a bunch of stills photographers who are always complaining ...
