Rendering MP4 for Video Download
Hello,
I am using Sony Vegas Pro 12 and need assistance. I am attempting to render a feature length file (total of 100 minutes) into a decent quality MP4 to sell as a video download. The film was shot in digital format (not HD) and each time I attempt to render the project, it comes back as a 5.6GB size file which seems excessive. Can anyone tell me what would be the best Render Settings to compress the file to something more in the 4.7 range? Or is that not possible? Is there an average file size I should be considering? Still kind of new to this. Thank you in advance.

I’m really liking the SONY MP4 stuff. I have a nVidia GTX560ti and it makes use of the CUDA when rendering, rendering takes about 75% of realtime – nice! I just did a BEST render 3k bitrate and got 1:47 mins into 40mb. That’ll mean roughly 2gb for 100 mins. And tested one just now at 10k bitrate and that was 81mb for the same 1:47mins
Try the different settings to get your bitrate.

To fit a video into a certain file size you can easily calculate your average bitrate which is what you will enter into the render as template.
If your video bitrate is 3Mbps (megabits per second) and audio is 160Kbps (kilobits per second), then you have a total bitrate of 3.160Mbps. Divide this by 8 to get bytes. Now you have the number of bytes per second for your encode. Just multiply by the number of seconds of your video to get bytes for the whole video.
Encoding to AVC will get you the best video quality for a smaller bitrate verses other codecs. I prefer to use Sony AVC.
If you want to try for low bitrates to keep your file sizes down then neither of the AVC encoders in Vegas are all that good at low bitrates. In this case I would suggest you encode in Vegas at a high bitrate and use Handbrake (x264 encoder) to encode to your final bitrate. You will be surprised how low a bitrate you can go with Handbrake and get a similar quality to the encoders in Vegas. A lower bitrate just gets your files sizes smaller.

Yup! I use Handbrake – that’ll be another s/w to download. Here’s Handbrake.

There’s a thread on the Sony Vegas forum called Why Handbrake? that is well worth reading.

More expanded,
Why x264? Because it is the best AVC encoder out there.
Why Handbrake? Because it is the best user interface front end to x264.

I’ve read on this forum from John Rofrano that we shouldn’t install any codec packages onto our computer, because that will cause problems with Vegas Pro. Does HANDBRAKE install codecs? Should I be concerned that this will cause trouble?

[Jerry Hart] ” Does HANDBRAKE install codecs? “
No. Handbrake is self contained.
I have heard about the don’t install thing, but it certainly has not affected me. I have K-lite standard installed. One of the supposed worst offenders.
I have only used Vegas Pro 12. It may have been different in the past.
K-lite standard only installs Directshow codecs. Vegas does not use Directshow. Impossible to have a conflict. K-lite Mega does have a couple of AVI (Video for Windows) codecs.
Vegas does not install any codecs of any kind into any codec subsytem of Windows. There are many. Windows for Windows, Directshow and Media Foundation. Quicktime is it’s own world.
