Exporting 1280×720
i am trying to export a 4 minute long HD video with audio out of premiere under 500MB. it has to be 1280×720 to upload onto the vimeo hd website (www.vimeo.com/hd) but i cannot manage to do it successfully under the maximum required size.
this isn’t just a lazy post, i’ve tried about 8 or 9 times using various settings and just experimenting, trying to figure it out myself but a deadline is coming up and i have had no success. as my computer is slowly dying and exporting takes up to 30-45 mins i am starting to become concerned about not meeting this deadline and putting my fist threw my beautiful screen!
any help would be very much appreciated and thank you for taking the time to read this topic.

Here’s the problem. It’s 4 mins long.
This is a quick guide to guess how big a file will be @ a given Constant Bit-Rate.Forumula:
(y = KB/sec)
y x 60sec = z
z x mins of video = W
W x 0.80 (80%) = your total sizeie:
(y = 3000KB/sec)
3,000KB x 60 = 180,000KB (180MB)
180,000KB x 4mins = 720,000KB (720MB)
720,000KB x 0.8 = 576,000KB (576MB)
Your goal is 500MB this is too big a rate.To go Backwards now…(hehehe)
You have a goal = 500MB or 500,000KB
So…
500MB / 0.8 = 625MB
625MB / (4) mins = 156.25MB (MBper min)
156.25MB / 60 = 2.6041667MB (MBper sec)
So your target to make the 4min clip fit down to 500MB is about 2.6MBper secYou will need to work off a VBR and make the low end of your Rate around 2MB and the Upper end about 3MB and the target to try and stay around 2.7MB

How many editors does it take to change a light bulb?

ahhh this helps a lot in understanding the rates, still unsuccessful though! i am trying to export with the media encoder, i dont no if that what i am supposed to be doing. it’s the first time i am exporting in HD so am un familiar with even the basic setup to export it correctly in the first place. i probably should of mentioned that in the original post. sorry.
how many editors does it take to screw in a light bulb? ha, lucky for me i’ll be going off to do 3d computer animation then!

Hi – I love vimeo and understand how difficult it is to get a good-looking video to post. A user there posted a video on how to convert AVCHD to the proper format for Vimeo. Maybe you can use the second part, depending on your source video. Anyway, give it a look. There might be something useful there. Good luck!

What was the final MB size of your video?
I’d like to know if you can post something that’s say
1024×576 instead of the 1280×720 as there isn’t much difference in the resolution.
But reducing your frame size means you can add more MB/sec = Better picture quality!

(otherwise without reducing the frame size your clip length is creating a problem that can’t be worked around)How many editors does it take to change a light bulb?
