Knowing your file size before export?

[jeff8]

Is there a way to find out how big your file size will be before you export your file. For instance, If I wanted to print to file a h.264 how would I know what the final file size will be before it exports it? Thanks in advance.

that is what I love about T5, I know exactly what the final size will be

this is very important because I often encode 20 HQ Fine files in one hit for mpeg2 elementary streams to go on dual layer DVD, T5 tells me the total size of all resulting files, so I can dial down the bitrate until I am under 7.6GB, this will allow headroom for menus and menu music

such a feature is desperately needed in EDIUS

Just send your export to the batch list.
You can see then the calculated file size for most file formats in batch list, except for QT based exports.
Adjustments to the exporter are still possible at this stage.

that won't be useful, because when added to batchlist, it is too late to adjust the bitrate, you would have to delete from batch and re-add with lower bitrate etc

and if doing 10 or 20 files, you will go nuts readjusting each one until total of all files fits on a DVD

the only thing that works is to add all files to the diskburner and then use the value that was calculated as a reference for your batch export bitrate

Deleting from batch list is not needed.
Just click the small icon near to the export path.
The exporters dialog window will open up to receive changes. ;)

I agree that information about size would be very useful in exporter window.

but how do you get it to calculate the total of all 20 files added to batch? the total of all files is the important info in order to see how it will fit an a DVD or Blu-ray

this is an absolute no brainer in T5 and it is made in Japan just like EDIUS

OK, this is another story.
As an DVD & Blu-ray author I always have to calculate the assets manually.
The good old Excel helps in this moment! :D

I've been using Mark's DVD Bitrate Calculator 1.1

Can't find official distribution site though. One member of Vegas forum

there is nothing in this world that can do what T5 can do when it comes to final size calculations of multiple source files, T5 is dead accurate

[Andreas_Gumm]

I understand your point, but the thread opener has asked for a way in Edius.
I just wanted to give him a helpful workaround to take control over it. :D
Besides this, any TMPEG tool puts me on the needle. You know my song about this. :D

Really?
All what it does is the same what you can do with calculator.
There is 0 magic in its calculation, because none exists. It's more down to actual encoder, specially if you use VBR, as many encoders are even only +- 10% accurate with achieving target bitrate.

yes really, there is no calculator out there that can look at 20 or more HQ files and you can dial in the precise total size of all 40 or more resulting elementary stream files

here is an example of quickly calculating the total file size of 35 source avi files converting to DVD mpeg ES to fit on Dual Layer DVD
