The 1520 butchered my concert video recordings

[themadpoet1]

I recorded a whole concert last night and while the audio quality was amazing, all the videos lag and skip throughout, almost like there's missing frames here in there . Does anyone know why the video would lag and skip like that? I'm so ticked off about it that I'm thinking of returning this thing.

Was Bluetooth on. I notice some issues on my 1020 when it's on and I'm recording.

Were you recording on an SD card?

 

[kevm14]

I'm going to say it was due to a slow SD card without more information.

Same thing happened to me the other night at my son's Christmas program. The video skipped every 5 seconds. I am using an SD card, so maybe that's it. Disappointing. 16 GB is absurd.

Slow SD card will most likely be the problem.

Go with a class 10 card.

 

[TravelBro]

SD Card you got is not fast enough for the phone.

What cards are people using? I'm going to try out a regular sandisk ultra card.

Heh 16 GB limit rears its ugly head.

 

[jmerrey]

I'm using this, which is a class 10 card:

Amazon.com: SanDisk SDSDQUA-064G-U46A Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter: Electronics

Do you guys know which codec Nokia uses for recording and whether its lossless or not? Keep in mind your SD cards are topping out at 30 MB/s which probably doesn't cut it for lossless video.

No, it's not lossless. Professional video cameras don't even use lossless codecs. It would use too much memory.

I have the same problem. I tried it on the SD card and on internal memory. It slips on both. I have a class 10 card.

30MB/s (assuming you really mean megabytes) is 240Mbits/s. That is *plenty* for mobile video, even if the file system imposes huge overheads. HD video on TV is max about 20Mb/s, and typically much less.
Is 30MB/s really the 'write' speed, which is what is relevant here?

1080P with a compressed codec maybe but I asked about lossless which uses far more. Regardless if it's happening with internal storage then the problem might be something else.

As someone else said, uncompressed video is not widely used. Certainly, no mobile phone does lossless video recording.
Full HD video at 25 frames per second and 4:2:0 colour is around 78MB/s = 624Mb/s without compression.

try again in airplane mode.

poor cell service has been the only thing I've found tip cause problems in video so far.

I just noticed something. I tried recording video on the standard camera and it recorded perfectly to the SD card. It's possible it's a problem with the Nokia camera.

 

[peacock93]

I will give this a try!!

 

[jmerrey]

I've recorded other videos that were fine. I'm wondering if high contrast situations, such as low light surroundings with bright light on the subject, is causing the problem?
