My Canon 700D stops recording when shooting video

[thealblackshow]

Hi guys,

I have just started shooting interviews for my vlodcast with my Canon 700D. Some are done using zoom.us and for the in-person interviews I'm recording with the camera. I've had a steep learning curve and have learned a lot, but the one thing I cannot figure out is how to keep the recording happening for the entire shoot. I understand that at 29.59 the recording will stop, however I was of the belief that it just starts recording another file and keeps recording, however this has not seemed to be the case every time.

When using it with zoom.us I now have a video that has a black screen every time I speak. I also have 3 in-person videos where I am missing footage. Sometimes it seems as if it wasn't recording when it was, and vice-versa.

I really don't want to go out and spend $$$ on an HD video camera if I can avoid it at this early stage of my project, so if anyone has any advice it would be greatly appreciated!

Cheers,

Al

I was also under the impression it would start a new file, but if read a few times the 30 min limit is so the sensor doesn't overheat.... I wonder if sensor overheating is what's causing the black screen?

Just been on various canon sites seems there is a lot of info out there some cit the SD cards as the problem
Can you post what meme card you are using

I believe the black screen is just the symptom of the same problem occurring in a different scenario. What I mean by that is that the camera has gone into some kind of standby mode, which has prevented the video feed from being recorded by zoom.us When not using zoom.us it's still going into a standby mode (or something similar)

Sure, it's a Lexar Professional 32GB SDHC 400x Speed. Here is a description - The 32GB SDHC Professional 400x Class 10 UHS-I Memory Card from Lexar utilizes UHS-I technology for a super-fast 400x speed rating, allowing for 60MB/s maximum read speed. It's got a Class 10 rating and a minimum write speed of 20MB/s. The card is great for capturing high-quality still photos and 1080p HD video with any SDHC- or SDXC-compatible camera, and satisfies the needs of pro photographers and videographers.

The 30 minute video limit is not about overheating nor about hardware. It is a UK tax, classifying longer than 30 minutes to be a high end video camera, with significantly more tax charged. Nikon and Canon and other others simply stop recording before 30 minutes to avoid the price increase. This is explained in several articles online, such as How the government broke my digital camera | Liberty International

You can always simply restart it, but really, a good video is composed of many rather shorter sequences anyway (often each only a few or several seconds), edited, lots probably omitted, but keeping the good stuff that shows something, and put back together. Watch any movie to see that. Any 30 minute run would be some very special situation, and no doubt a pretty crude and boring video.

Here is some data on average shot length: https://stephenfollows.com/many-shots-average-movie/

Hi well it look like that you have the sad card covered. I am out of ideas hope that you solve the problem

Yup .. that is by design. The 30 mins recording is arbitrary to avoid being classified at Video Camera. If you need to record continuously for a interview or document a event type video, I personally think a camcorder is better. Otherwise, you just need to record them in sections.

Well, you can take a look at this and use it at your own risk.

Their FAQ:

How do I record for more than 12 minutes?

• H.264:
  • Lower the `bitrate`_ (CBR 0.4 will let you record continuously for 30 minutes).
  • Use `Movie restart`_, but you will lose a few seconds when a new file is created.
  • 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).

• RAW:
  • Can record continuously until the card gets full (no 30-minute limit).
  • File sizes are huge; you may want to reduce resolution and/or FPS; also use a large card.
  • exFAT recommended; otherwise, when creating a new 4GB segment, the speed drops a bit and recording may stop.

• External HDMI recorder:
  • Enable the Clear Overlays feature to hide the focus box and the 16:9 bars.
  • Make the half-shutter button sticky (Prefs menu) to prevent the camera from turning off LiveView after 30 minutes.

It's a well known challenge when using a DSLR for video. Most of the time there are pauses in a speech or show and you stop and start the video again manually. If it's to be unattended camera then a video camera can be used or best is to connect to a computer and use a software product like "Control My Nikon" and record in the computer.
