OT: Another Upload Question- please help =)

i c e wrote on 3/2/2009, 11:02 AM
Hello,
I am trying to upload my video to Vimeo but I am having a problem. My video is 32 minutes loooong and 1.5GB. Max Upload for Vimeo (plus status) is 1GB. I really really don't want to chop it up.
Is there any way for me to further compress it without losing significant quality to get it under the 1GB mark???

If anyone had a solution they would be my hero!!! =)

Thanks a million,

Further compress it from what? (what is it now?)

huh...yeah.
Further compress it from the H.264 (MP4) file that it is now and make it smaller (somehow?) in size so I can upload the whole thing at once.

Just wondered if anyone might have any ideas?


Thanks,

Josh

The size of a file is determined exclusively by bitrate multiplied by program length. In order to make a file smaller in size while maintaining the same length, you need to lower the bitrate to something slighly lower than 66% of the bitrate you used in the first place.

I would not recommend compressing it again.
Go back to your source / project and render from that at a lower bitrate. Apart from the bitrate, keyframe interval can have an impact on file size. Vimeo recommend 30 frames.
Note also for best results you video should be at 24p.
As you have the Plus service you can also use 25p and Vimeo will not convert it to 24p.

Sounds like I might be able to figure this out, thanks a ton.

If I can shoot two more questions:
I finally rendered the project and it actually came out to 600mb way less then what I had calculated (I should have known). No I am really hoping to get it to 500mb so I don't have to get Plus, (It would really hurt right now to have to shell out another $60).
So
1). If I reduce the bit rate how much quality will I loose? Right now it's at 2.5million and looks really good. What should I try next?
2). I have no idea what 24p means. (sorry) But I saw that in the settings.... will I loose quality going that route?


Thanks a million guys,

Josh

Heya if anyone could hit me back on this one before it falls off the depth chart that would be super cool hoping to upload tomorrow. ( I have to go to a cafe because my download speed here is like 3kbps a second!)

Gracias,

Josh

I don't think 2,500,000 bps is adequate for HiDef on Vimeo. Should be at least 5,000,000. It's not going to look like what you see in a QuickTime viewer or Windows Media Player on your PC. Render a small section and upload that for a look. It will depend on the content. To some degree, the look is subjective to what YOU think. Squeezing ever ounce of quality out of highly compressed video is really a art. There are many many variables and one size does not fit all. Personally, I break up longer videos. Much easier to handle. Viewers are use to this. Part 1 and Part 2. No big deal.

"I have no idea what 24p means. (sorry) But I saw that in the settings.... will I loose quality going that route?"

24p = 24 frames per second Progressive i.e. not interlaced.

You will not loose quality if you shot 24p or 25p in the first place. If you didn't one way or the other it's going to end up as 24p anyway because that's all Vimeo support. If you pay for their Plus service you get the added option of 25p which is handy if you happen to live in a 50Hz country.

As Vimeo themselves recommend, it's best to do all conversion yourself. That way you have control. If it looks a mess after you do it yourself you get to fix it yourself. If Vimeo makes a hash of it you have to fix it and then upload it again.

I'd seriously suggest you take on board suggestions above of uploading a short piece as a trial. Waiting hours while a full work uploads plus waiting for Vimeo to finish encoding it only to discover you have a problem would be VERY frustrating.

Thanks for getting back to me. I really appreciate it.
Very good idea (s). I will defenately do this. I am rendering everything from my original files in Vegas so I'mk not re-rendering anything.
Also I am not using HD. Just Widescreen DV.

So I'll change the frame rate to 24 instead of 29... and I will try to render it at 2million bit rate instead of 2.5 and maybe I get it under the 500 mark. If not I'll take your suggestions and do it in two parts.

take care,
