How to change Blu-ray size

[nilsb13505332]

Hello,

my question is simple and easy to explain. I will be using Encore to create Blrays. Most of the time I work with 25gb disks. To test everything, I created a simple ISO with just one menue and one film. After the ISO was done, it was full 24,9 gb large. The problem is, that only about 22gb fit on the disk.

how can I adjust the size of the Blu-ray manually so Encore doesnt inflate the file to maximum 24,9gb?

or will it detect that there arent 25gb available?

thank you

If your videos are not Blu-ray legal in Encore's opinion, it will show them as "Untranscoded" in the project panel under "Blu-ray Transcode Status." When this is the case, Encore will transcode/retranscode them using the settings shown in the "Transcode Settings" column. You can change the settings by picking a "quality preset" or creating a custom one.

If the setting is "automatic," Encore will use bitrates to fill the disk. The goal is always to bring Encore BD ready assets (separate files for video and audio) and at bitrates that your total project is the right size. Automatic was most useful when using dynamic link, but many users never liked that workflow. Encore did not provide the best quality.

This gets into bit budgeting:

DVD-HQ : Bitrate & GOP calculator

If your video is legal, it will show "Do Not Transcode" in the status column. In that case, as you note, you may be running into the fact that a 25GB BD disk is only 23.3 GiB. In Encore, it says it is tracking GB in the build panel, but it is really tracking GiB.

Another possibility is that an iso may be of a size that cannot be burned to disk if it were a single file, but will fit when burned as a BD image. But I think you are right; the iso is too big.

When you finish editing in Premiere, go to File > Export > Media and choose H.264 Blu-ray as the export format, and then choose an appropriate Preset best matching the content you are encoding for Blu-ray.

What is the total duration of the video being encoded for the Blu-ray disc? Plug that into the DVD-HQ bitrate calculator Stan linked to, and that will tell you the proper bitrate to use in Adobe Media Encoder so that the encoded material will fit the Blu-ray disc, without going over on size. Assuming all variables in calculator are set correctly of course!

You will have to export from Premiere again with a lower bitrate to make the file fit.

I find it interesting that people are having issues if Encrore "inflating" a Blu-ray file size. I have an issue with it DECREASING the file size. I have a 22GB HD file and when I bring it into Encore to burn a BD, it ends up being only 15GB wish so much empty disc space. 
When it comes to INFLATING a video file, I find that to happen when burning DVD in Encore. Every single DVD I have ever burned in Encore, as small as 1.5GB has burned the entire disc with no empty space left over. How and why is that? Anyone?

Pardon my typos. I see that I cannot edit to correct them. Sorry.
