Quick question about making gaming videos for youtube

[just Scott]

Just a quick one. Roughly what filesize should I be aiming for when making videos? I just recorded a gameplay and it's 8 minutes long. I'm encoding it right now and it's going to be about 800mb (1080p video). That seems a bit high to me, but I've never worked with videos this size - only less than 1 minute clips before. I'm using MeGUI to encode this in H264. x264 preset on the very slow setting, 20 CRF quality. I figured using a slow setting like this would make the filesize quite small?

I render all my videos 1920x1200, the end up around 2Gb for 30 mins, so 1Gb for 15 mins. Yours seems a little high, but not too large, what bitrate are you rendering at? Google recommend around 8,000 kbps, so if you're much higher than that then its probably overkill. Personally I render at 10,000 kbps, even though youtube doesn't support 16:10 yet.
Self pimping link so you can see how those settings render for me.

I don't use bitrate, I use CRF: http://mewiki.project357.com/wiki/X264_Settings#crf

Although I might try bitrate based encode next time. Nice quality on your videos btw.
