Different export settings in the same video

Hey everyone, I'm working on a video that has two different formats - 720p and standard def footage. However, when I export under the recommended H.246 settings (for vimeo), the file size is too big to upload and I would rather not split it up.

I'm wondering if there is a way to split up the settings to change the bitrate for individual scenes to export? By lowering the bitrate for the standard definition scenes, I'm sure it will be just enough to be <500mb. If I could only find a way...


Thanks in advance guys!

You mean you want to control exactly where the bitrate changes? Not with AME. Perhaps with other software.

Try tweaking the VBR limits and use two-pass.
 
Thanks David, I'll try exporting with two-pass. Hopefully AME will recognize the standard def video and allocate the bitrate and size accordingly.
 
What frame size are you exporting to? That will have an effect. In fact, having to uprez the SD footage might increase the bitrate.

Keep in mind that variable bitrates are more about saving space where there is less motion -- less difference between frames -- because of the nature of interframe compression. The less difference you have between frames, the less information you have to store.
 
I'm exporting 1280x720....and the SD footage that I have is originally 720x480. No good?

Did I uprez it if I clicked 'Scale to Frame Size'? It ends up being a smaller picture within the 1280x720 frame, which I don't mind at all.

I'm still waiting for it to finish exporting, but after reading your last post, I may have to find other ways to resize this.
 
Well, if it's windowboxed (within a black square) mixed in with the 720 footage, then it might help you. It's all about differences between frames, and if the frames all contain a black window, that's much less difference to store.
 
Thanks again, David. I had to deal with some audio issues first before I could export the final cut. There's 2 hours remaining... When I had it set on VBR one-pass, the target bitrate was 5 and the max bitrate was also 5. That gave me a predicted size of 684mb.

Now I set it on VBR two-pass, and I'm wondering if I should have lowered the target bitrate so I could have a product <500mb. Oh well, we'll see in two hours!
 
David, thanks for your advice! While the VBR two-pass did lower the file size significantly, it was just shy of 500mb. Instead of tweaking the target bitrate, I went ahead and bought a Vimeo Plus account, opting for a higher quality video.



Check it out! I hope you enjoy it. I ended up boosting the target bitrate to 7.5.

That's a sweet movie. I'm sure your grandma and the rest of the family will really appreciate it. I'm from Hong Kong too so it's a bit more 親切 to me. =)

The thing I don't like is the steadyness of the video. Maybe time for a tripod?
 
Thanks, Taky!

They all loved it =D.

I do agree about the steadiness - the entire rig weighs about 18lb, because I also attached a portable dvd player to it to act as an external monitor. Unfortunately handheld was the only way to shoot the dinner, because of the limited space and the number of shots I would have to do...18lb on your shoulder for a period of 3-4 hours definitely took a toll on me!! Thank you again for your kind words!

Btw, I checked out your wedding videos - they're beautiful! What kind of filter do you use for the soft misty image??
 
Hi LuckyMovie, thanks for your nice comment.

I use a Soft Focus preset comes with my Matrox card to create such "soft misty" image. Premiere doesn't come with such filter. However, with a little trick, you can create this effect easily with Premiere. The same trick can be used in Photoshop too. I posted it in my blog here -> http://lacolorshop.com/blog/view.asp?id=59
