Help with HD rendering file size

[Grim 0]

So I made a video game music video, captured with my Hauppauge HD PVR. The bitrate of the raw files are roughly between 13-14mbps.
I use Sony Vegas 10 Pro to edit and render using Sony AVC/MVC setting, which make mp4 files. I render @ 14mbps & 59.940fps, 720p
File size for a 4 and a half minute video is 351mb. Is this normal? I have no problem with file space, other than that larger file take longer to uload to youtube. But is this too big. Should I be able to compress it smaller without degrading quality? Some of my friends think my file sizes are extreme, so I would love for anybody to help clear this up for me. Thanks.

To get the highest quality from YouTube set the bit rate high but within their max file size limits. Youtube will re-encode to a very low bit rate. The higher quality file you send them, the better their re-encode will look.

I render @ 14mbps & 59.940fps, 720p... File size for a 4 and a half minute video is 351mb. Is this normal?

Sounds about right:

file size = bitrate * running time
file size = 14 Mbit/second * 270 seconds
file size = 3780 Mbit
file size = 472 MByte

For Youtube, render 29.97fps, 720p @ ~8-10 Mbps. Lower the bit rate if you exceed Youtube's max file size.

Youtube converts everything to 24-30 fps progressive. There is no point to sending them more.

And for uploading to Youtube you might as well cut the frame rate in half.

Yeah, I render a temp file @ 10mbps for uploading to youtube.
But for my personal collection, 14mbps seems slightly, but noticeably more detailed.

Thank you for the helpful responses.

For big screen viewing I do all 720p @59.94 fps. Can't stand jerky 29.97p.

30p is for web only.

Hi Grim 0, I´m a gamer upload videos and use Vegas HD too.

My all sources are 720p@60fps PS3 or emulators videos.

Use VIDCODER with X264/mp4 to encode for YT. (I will put my screens configs soon)

For 480p use 4096 bitrate
For 720p use 6144/8192 bitrate
For 1080p use 10000/12000 bitrate

Any question, reply.

Forget bitrate and use constant quality encoding.

Forget bitrate and use constant quality encoding.

The Sony AVC encoder lacks CQ settings, only max ave min bit rate.

Wow, I downloaded it an re-encoded my video using the default settings.
It cut my file size by 103mb and I can't see any loss in quality. Thank you so much!
