1080p vs 1440p File Sizes

[Gabenfoodle]

So, for about 5 months, I've been using a 1440p Moniter and uploading stuff without downscaling it to 1080p for YouTube. But hour-long videos tend to be a good 15GB or more. Seeing as I often record these videos en masse, it often takes me a few days to upload them.

I was wondering, if, by comparison, anyone knew how big an hour long 1080 video was?

Any help would be much appreiated.

Maybe problem in internet?

Umm are you using uncompressed (raw data) videos to upload?

For Youtube video uploads, use codec compression:

Container: MP4 format
Audio codec: AAC-LC
Video codec: H.264

If you wanted 1440p...
Video Bitrate - set to around 16 to 24Mbps

If you wanted 1080p...
Video Bitrate - set to around 8 to 12Mbps

Lower video bitrate will mean a lower video file size, but slightly less quality.

The codec compression however will greatly reduce video size from GBs down to MBs, without any noticable quality loss. This should be used before uploading any video to the internet. You should be able to get it down to 100-700MB in size for a couple hours worth of video in 1080p resolution.

You will probably find Youtube formats it for you, but you are just wasting time uploading by getting it to do it, rather than just doing it yourself.

What application / graphics card are you using to create the videos?

Consider downloading the "K-lite Codec pack" (Google search for it), then seeing if you have the option to use the H.264 video codec and AAC-LC audio codec, under your video recording application, it should be able to use it on the fly, saving you a lot of space and time. Else get a H.264 encoder and apply that to your raw video before uploading it.

Azza summed it up pretty well; I'm assuming you use Shadowplay? 15GB for 1 hour at 1440p is roughly what it would record... I'd be careful about re-encoding already encoded footage - Shadowplay already uses lossy compression - default is 50Mb/s for the video (H.264). Audio is locked at 192Kbps for the audio (AAC) - re-encoding absolutely shreds the quality

If you are using Shadowplay consider lowering the bitrate manually; it depends on the game but should still look quite good and the file sizes will be much smaller.

Shadowplay has an option to record at 1080p, and I was wondering how much I would save if I did that

It depends on the bitrate; Shadowplay by default will allow you to record 1080p anywhere between 10Mb/s and 50Mb/s - There is a way to push it upto 130Mb/s but for 1080p that is pointless.

It also depends on the framerate as well; higher framerates will require a higher bitrate otherwise you get loads of artifacting. For 60fps give 20-25Mb/s a go and 30fps give 15-20Mb/s a go.

Note that Hardware encoders (Shadowplay + NVENC encoder on your GPU) are a lot less effifient compared to sofware encoders (stuff that Sony Vegas, Handbrake and Premiere will do)

If you are using Shadowplay, then by all means set it to 1080p, if desired. You will save a lot. However, it's more keeping an eye on the video bitrate... that's where the size adds up. Keep it in the range as mention before, depending on the resolution. Youtube will cap it to the max range anyways, so there's no point going over that.

It's actually quite tricky working out exactly how far YouTube compress each video; there is a lot that goes into it - especially considering YouTube render out the video in two different codecs - AVC (H.264) and VP9 so it can be accessed of a wide range of devices and browsers - anyway YouTube recommends 12Mb/s for 1080p@60fps. If I uploaded a video with the exact same specifications by the time they render it out it would look pretty shoddy - especially coming from a hardware encoder. However if I uploaded a the video with a 20Mb/s bitrate by the time it's fully processed it would look much better.

YouTube use software encoders for compression; with a hardware encoder you;ll want to use a higher bitrate - that way when YouTube does compress the video it won't be completely butchered.

It's not that hard to work out, when they tell you... well at least some guildlines / recommended.

That's not actually what YouTube compress the videos to; that's the recommended bitrates and codecs for uploading a video. It varies depending on the video as to how far they compress it as to what the bitrate will be.
