Nikon D3200 Video Help! Recording Interrupted Please Wait

Hello forums! I purchased a D3200 4 days ago and tried to record a test video for the Tackstar SGC-598 microphone. The problem is after about 1:21 the camera stopped recording with the message "Recording Interrupted, Please Wait." appearing for about 4 seconds before letting me continue :mad:. The message stopped the recording but pictures take at just fine speeds in burst mode. My card is a SanDisk Pixtor 32gb Class 10 48 mb/s SDHC The card was purchased then immediately formatted in the camera. The recording seems to stop at random times ranging from 2 mins to 14 secs.Any help would be much appreciated.Thank You!

I have no knowledge of this question, but a google search finds the same complaint about many Nikon models, going back 2 or 3 years...

nikon recording interrupted - Google Search

I don't know if there is any solution there or not, but the answer does seem unknown. But possibly one good suggestion there is that if you are using Maximum 24 bps bit rate, try dropping it back to Normal High, 12 bps.

If that helps, it suggests a faster card is necessary. The manual says: (D3200 Reference manual, page 177)

Cards with class 6 or faster write speeds are recommended for movie recording.
Recording may end unexpectedly when cards with slower write speeds are used.


I have never seen the problem myself, but I use the Normal bit rate, which is quite good.

It probably is a very good question for Nikon support.

The card listed is Class 10

Changed to normal quality. Can't find problems but its a bummer that you can blow 550 on a camera that
you have to resign to lower quality then what the camera offers.

Nikon could provide more specs, but it does suggest a faster card is necessary for the maximum bit rate. I think your card is faster than some, and I think it is UHS, but write speed is pretty nebulous on memory cards. You might try a different faster card? I use the fastest 1000x cards in my D800, which works OK at Maximum, but I normally use 12 Mb/sec (smaller files).

Is the normal bit rate causing a problem? 24 Mb/sec is a maximum kind of value. Network television broadcasts around 15 Mb/sec, and very much of our cable/satellite TV is significantly less, maybe 8 Mb value, hopefully. 12 Mb would be a real luxury on much cable TV. :) Youtube HD is about 4.5 Mb/second. How much does an interview need? :)

It seems good to have a workaround, and my own notion is that the Normal 12 Mb/sec bitrate is more than plenty, and should do fine.

Would normal quality video effect the ability of color grading in post process? Or cause artifacts?

Also thanks for your help.

I think the idea is about artifacts, I don't know about color. Video is not my best field, I am still a novice there. :) I use the 12 Mbit rate, and use Cyberlink PowerDirector for processing, and I find no problems at all (vacation scenes mostly). I also have a little $300 Canon camcorder, which has five quality rates, but Mbit/second is never mentioned once. Primarily they relate it to file size and record time.

I find no explanation of bit rate to very comprehensible, other than more is better. Video is often Variable Bit Rate, using only what is needed for the scene.

Nikon says at least Class 6 cards for video. Your card says Class 10, which is the highest number Class is rated. Many cards are faster today, but they stopped numbering at 10. Class 10 means at least 10 MB/second minimum, to be true of both read and write directions (minimum). The card can be faster (the Class number only goes to 10, sort of an old style rating, but considered adequate for video). 8 bits per byte, so 10 MB/sec is 80 Mb/sec, which is more than 24 Mb/sec (minimum), yet obvious problems exist. I have no explanation. MB is Bytes, Mb is bits.

If I found the correct card, your card is rated 200X (printed on the card, I think). A dumb way to rate things, 200x means 200 times the old first original CD read rate of 150 KB/sec, so 200x means read speed of 200x150KB = 30 MB/sec... Which is more than Class 10 10 MB/sec minimum. 8 bits per byte, so that is 8x30 = 240 Mbsec. But 200x is Read speed, Write speed is normally significantly less. However Class 10 should be at least 10 MB (80 Mb) minimum. I have no explanation why more seems needed. It would be a good question for Nikon support, but I doubt they will volunteer anything. The telephone people probably don't know. Sandisk support possibly could be more helpful?

I know it is not your goal, but I would have no issue with the normal 12 Mb/sec rate. It is pretty darn good, and will be better than most any cable/satellite channel quality.
The only exception I know is Verizon FiOS cable, which is fiber to the house, with huge excess bandwidth, so they do not recompress any channel content smaller than they receive it. The others all do. Some a lot. Satellite TV too. Their few hundred channels all have to fit into their available bandwidth.

So I am just suggesting to try it once, and to find that any actual problem actually does exist before being too alarmed about it. You may like it. :)
