PowerShot SX70HS - How to Record a Video

[fweiss1]

I've used this camera for photos and now I have a need to video/audio record a presentation and would like your suggestions on how to based on the following:

Here's what I have:

• Estimated time is 60 minutes
• I have two fully charged Canon OEM batteries LP-E12 6.3Wh
• I have one SanDisk Extreme PLUS 128gb SD card - will have no data when I start
• No external mic at this time
• Probably mounted on a tripod

Questions/Comments:

• I may have access to a wired mic, possibly a clip-on mic - how to use these?
• Can I use a wireless mic?
• If only camera mic, what is range, is volume adjustable or only on playback?
• Estimated battery life on a full charge?
• Estimated memory usage?
• Video range - how close/far away?
• Tips, published directions/instructions?
• Known how to on YouTube?
• Anything else?

Thank you in advance for your assistance, support, guidance.

“ Estimated time is 60 minutes.”

Let’s pause right there. I believe that camera model has a 30 minute recording time limit. The actual limit would be 29:59.

We would have to do what you can do is read the manual. I suggest you just start practicing. Some questions we can’t answer because it depends on your situation.

I just checked the manual and you can use an external microphone

Can I stop the recording after 30 minutes, then start again and again?

[kvbarkley]

Yes. You can make as many 29 minute recordings as you like. If you use a high quality video setting there is also a 4 GB file size limit, I believe.

“ Can I stop the recording after 30 minutes, then start again and again? “

Yes, you can restart it. All Canon consumer cameras had a 30 minute limit during the time period when that model was first released, so as that wouldn’t be taxed as a camcorder.  

The entry and beginner level DSLRs all stopped automatically.  The more advanced DSLRs could automatically restart recording another 30 minute file.  The user could then combine the files into one longer video on a computer.! I am fairly certain that point and shoot cameras like yours did not automatically restart.

Be aware that there are other constraints that can negatively impact max recording time.  File Size.  Canon has a couple of different file systems available n their cameras. I believe your camera has a 2GB max file size.  There should be tables in User Giide that explain this in more detail. Memory card capacity and performance can also impact recording times.

The 30 minute time limit should not be an issue. I just read the specs.  The stops recording, but automatically restarts using a new file.

The video specs report max 4K 75 minutes of recording time using a SDHC U3 32GB memory card. You might try downgrading the card from SDXC.

Thank you!

Can I use a USB power supply such as a power bank, plug into a charging block - using appropriate cables? 

The tripod mount prevents me from opening the access door to change batteries/memory card.
