Anyone experienced with Video Recording Software?

[Axe]

I've just had a go with Bandicam to record a reply of a test rally and even when using the Youtube preset 1080p I managed to have generated a file of 1.45 GB for a 3.5 mile long stage.
Is this normal for uploading to Youtube?

Although I am upgrading to a cable 108 Mbit connection within the week currently at present I have a 100K a second upload which would take about 7000 years to upload. Are these figures normal?

If anyone can share any tips and tricks I'd appreciate a discussion on this.

hmm, I am using OBS studio and I have a couple of recording on the side. So 60 FPS, 1080P, about 580 megs for 0.5 hour of recording. Now, I have a recording from another game and it is 780 megs for 15 minutes. So there is a bit of variation. I do live streaming on facebook (I know old), and using their settings (30 FPS, 720 P), it runs really smoothly.

Thanks for the reply and the details but I'm not sure where the 'fps' is dialled in here. Is this fps in the game you are speaking of which makes a difference to recorded file size?

I can imagine 720p & 1080p making a difference but does game fps also?

are you using an Nvidia graphics card?...they have a pretty good recording engine thing that works really good..I just forgot the name of it now.

I am actually. Thanks for the info. I'll research further :-)

you are most welcome

Nvidia has shadowplay. you can also access the NVENC hardware through OBS.

60FPS is prefered for a game like this because its preserves fluidity of temporal motion. Watching a racing game at less than 60fps feels like garbage.

When I used to record Dirt Rally runs, my source upload would be several gigabytes in file size, because I prefer to maintain as much quality as possible. Garbage in, garbage out. Remember youtube re-encodeds anything you upload to it.

Also its bitrate algorithms suck for high motion games like racing games. Even uploading a losslessly compressed file it would trash my imagine quality on the uploaded encode.

Recording a 60fps file vs a 30fps file results in practically negligible file size increases. In fact, if you were to record in the highest quality you could, then chose to re-encode against before uploading, using more CPU intensive settings, etc. It would likely look just as good and consume less bitrates (lower file size).

your file size is going to vary wildly depending on the amount of detail in your gameplay footage, how fast it is moving, and also what quality targets your encoder settings are aiming for. It will apply different levels of compression based on the source footage and encode settings. That's why you will get unpredictable file sizes.

If you want predictable file sizes you have to tell it to use a target bitrate, and then it will adapt the image quality based around making it all fit into that bitrate.


You really have tons of options for how big your final upload turns out to be. If you're just looking to record and then upload, you could probably accomplish that with shadowplay, or OBS (OBS would require you to know what you're doing somewhat)

It's all about how elaborate you want to get.

The FPS was the records from Facebook (limiting factor). So I run the game at 60 fps but the live feed can only go 30 FPS. not sure why. However, I can do the recording at 60 no problem and it runs smooth. All the recorded files on my hard drive were 60 fps game and recording at 60 fps.

Ah thankyou so much gents. I see there are some factors here I would never have even though of meanwhile. Lots to learn and understand.

All I need to do now is unlink my steam account from my old youtube account and I'm golden. Anyone know how then I'd appreciate the heads up.

I have gone through the process but it just doesn't work. I keep going around and around :-/
