Is there a frame size calculator for Mac that gives an optimal resolution to use when the video length, target size, audio bitrate, etc are input?
I'm looking for something just like this: https://www.videohelp.com/tools/Aspect_2
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

How about just using ffmpegX or MPEG Streamclip? They will tell you the resulting size (MB) of the file when the other info is set.

I don't a program to tell me the file size. I have a preset value based on the media I plan to use in mind. What I'm looking for is optimal resolution dimensions based on file size (and hence video bitrate based on video duration) and audio bitrate I plan on using.

So you're looking for something to tell you information like this website? Click Here

If you don't care about DVD standard, you can use whatever resolution you want. -

In general, a lower resolution allows for lower bitrates for any given codec. But some codecs give better results than others at any given bitrate. Using 700MB as the given information to determine a resolution is impossible without knowing the duration so you can calculate the bitrate.

Bit rate and file size are directly related. Both are independent of frame size.
If any "calculator" is relating the two for a given codec, it is using a subjective relationship.Recommends: Kiva.org - Loans that change lives.

A program can't accurately determine that unless it examines the video and tests it for compressibility with the codec you plan to use. Some videos compress much more easily than others. Look at the three videos in this post:

The one with the lowest bitrate (the smallest file) looks best.
