I am taking regular videos with my new H5. RES: 720, FPS: 30, FOV: MED. Only 20 minutes of video result in a 3 GB file. I would not expect such a size even from .avi. For .mp4, I saw many quality videos which fit an hour in little more than 0.5 GB. So, how do I produce normally-sized videos?

An interesting addition. I loaded that 20-minute video into handbrake (a nice program indeed) and simply re-encoded it without changing the quality. The file became 373 MB. This suggests to me that the camera's encoding is faulty... I hope that I am just missing something.

Also, while on the topic, I tried to locate the encoding quality settings in the camera, but could not.

well funny you should say that. I made a video using GoPro studio, saved it as 1080, then decided to do a 4k version. The files were exactly the same size despite the change in resolution, no one came up with a reason why

Could you please try the same settings as the ones I quoted? The 3 GB size I reported is the size of the file as stored in the camera without any software transformations applied to it. My camera just eats >100 MB per minute of recording, which is crazy!

Also, as another data point: when I loaded the same 3 GB file into VLC and "converted" it to mp4, it took 199 MB... It looks to me like the camera is not using any compression at all...

Hi guys,

I believe this is related to bit rate. The Hero 5 Black and Session have a bit rate of 60Mbps, same as Hero4 Black, whereas the Hero 4 Silver has a bitrate of 45Mbs and Session have a bit rate of 25Mbps.
I have the Hero 4 Black and did a 20 minute video with the same settings you posted and got a 4GB file size for the video.
Theoretically, a 20 minute uncompressed file with 60Mb/s bit rate would have a file size of 9GB, so for sure there is a certain level of compression that happens with H.264. I am assuming that you previously owned a Hero4 silver or session and therefore your previous 20 minute recordings had a much lower file size.

Please note that when using handbrake/VLC and any other file conversion software they usually compress the files further by reducing their bit rate.
720p HD standard bitrate for upload range between 5Mbps and 7.5Mbps, which is almost 5-10 times less than the bitrate GoPro uses.

Hope this information helps

Is this configurable in the camera? I mean, with almost 10 GB for an hour of video, the Micro SD of 32 GB is only good for 3 hours and an external storage of 1 TB is filled with only 100 hours (unless one takes the pain to put every video through some piece of software)! Also, these huge files take very long to upload... So, I can't imagine this configuration being fixed. Also, I don't think I can perceive the difference in quality due to a higher compression ratio.

To be more precise, I understand that the bit rate is probably fixed. I am asking whether the camera can be configured to use a higher compression ratio. Or, short of that, is there any way to get smaller files to save space on the Micro SD?

To my knowledge there is nothing you can do about it. There is no way for you to reduce the bit rate or increase the compression for smaller file size, on the GoPro that is.

Well imagine you back your data up with Quick or studio?

Data adjustment can be done via firmwre by gopro offering High, med, Low? Using protunes really does not help as it makes it the maximum.

Shoot in the lowest res is not the answer or another camera, sorry but that is how gopro works. I convert and toss, ifthat is an issue for you, or zipgile it for your own compression for saving.

So, what do people do? I mean, if you are up in the Rocky mountains with your snowboard, all you can shoot without getting back to the computer is a few hours? Don't you think that's ridiculous?
Another thing I find very strange is that the same bit rate is used for all resolutions, so that going to lower resolution (such as 720) does not make the files smaller... But isn't that precisely why people use lower resolution -- to save space?

I did not understand most of the answer (it looks like you are using an automatic translator from another language and it does not always do a good job). However, the line "data adjustment can be done via firmware by gopro" sounds promising. What exactly did you mean?

Got to Love Siri.

I said: If gopro allows firmware they can write MBBS quality .

GoPro can offer you what you want only if enough people give feedback at gopro.com support? Bitrate can be controlled by a High, med, and low setting done in the camera. If you want to store your footage compress your files in a file folder, but if you use Stuido you are going t owant to save your back up that really eats space.

Use the lowest resolution if it Decreases the file size and lengthens the video? Bare minimum for a good shot is not 15mbbs it's like 7mbbs, not for this action camera.

FISH:wink:

Your rocky mout remark:

you dump it to your other devices on you, like a wireless driver.

Changing the resolution does make a difference in file size.
I just did 2 tests:
1. 1 minute of video @ 720p 30fps W = 341MB
2. 1 minute of video @ 4K 24fps W = 454MB

Honestly, I don't see an issue with it. If for instance you were limited by internal storage then yes it would be a problem but the fact that you can purchase additional SD cards and some go up to 128GB then you have enough options to overcome any of those issues.

Please, where exactly in the menus is it located? (unless you mean the field of view and by "high" and "low" you mean "wide" and "narrow")

Use the lowest resolution if it Decreases the file size and lengthens the video?
What do you mean by "decreases the file size and lengthens the video"? Why question mark at the end?

At least two issues:

1. The need to always run videos through compressing software. This constitutes considerable time overhead if you have many files (i.e. hundreds, a minute- or two- long each). The alternative is using multiple expensive storage devices or an expensive cloud service (actually, are there clouds with unlimited storage and no need for storing things on your computer as well? i.e. Dropbox business account is excluded)

2. The amount of money things like 128 GB micro SD cost.

Hi mgoldenb,

1. I am not sure if you experience with tape media but back in the day, we used to be limited by the amount of space on tape media which was usually 1-2 hours/tape. In addition transferring the media to your computer took real time because you had to play it back to capture it in file format.

Nowadays, you can fit almost 3 hours of HD footage on a 32GB sd card that sells for $20 and buy a 1 TB external drive for $54 (Which can hold about 30 hours of footage). Clearly there are a lot of perks that we have these days.

2. A 128GB sandisk microSD costs $65 and can hold almost 11 hours of 720p HD footage. This one works with GoPro based on reviews https://www.amazon.com/SanDisk-Extreme-microSDXC-Adapter-SDSQXVF-128G-GN6MA/dp/B01DYN4VPE/ref=sr_1_1?s=pc&ie=UTF8&qid=1477698735&sr=1-1&keywords=128gb+micro+sd+card+u3

Thank you for your answers. This makes sense. However, you do not always need HD quality. In fact, it is not easy to see the difference in quality between a 3 GB video and the same video compressed to 200 MB. Just like people enjoy having hundreds of hours of music on a single USB key, it is sometimes great to have all your videos on one drive. I think that configurable compression ratio would be a great feature. Also, it's probably already in the camera's software, so why not make it available through the user interface instead of forcing on the user an arbitrarily chosen ratio that is hard-coded?

Another small point (small for me, since I do not use PLUS). How long does it take a PLUS user to have a 10 GB video uploaded to the cloud? I am sure it takes longer than the length of the footage itself... With better compression, this would happen in real time and many hours could be stored on the cloud.

Hi mgoldenb,

I see your point in wanting to be able to store all your videos in one place like your music collection, but you need to take into account that the GoPro has 2 goals: 1. To be the best action cam out there and 2. To be broadcast quality. Both require it to have high data rate.

Here is a post I found that might help explain things, it is a bit dated but still relevant.

Thank you for the informative link. However, you did not understand me. I did not propose to lower the bit rate. I proposed to retain the high bit rate, but to let the user specify the compression ratio. That is, instead of me compressing the video after transferring it to the computer, the camera would perform the compression before saving the video onto microSD. It already does that, only with a fixed low compression ratio.
