Best compression for 360p video on blu ray?
I have 155 video clips around 99 hours that are natively 640×360 MPEG-4 Codec H.264, ACC. I tried to burn a few on a BD-RE using Toast 10 without any re-encoding from Toast and the quality wasn’t as good on my big screen as when I watch the videos on the same screen from my computer using quicktime player at full screen. So what I want to know is what is the best way to re-encode these video’s using apple compressor to burn on blu-ray using toast 10.
I tried using *this compressor setting which looked a lot better when I only burned a few clips with Toast 10 not re-encoding but with the resulting larger file sizes meant I could fit less on the blu ray. I let toast re-encode the 49 clips to fit on a single 50 gig BD-R DL but the resulting quality was poor.
For comparison the same 49 min clip at 640×360 was 1.08GB came out at 6.62GB when converted.

I also have 155 short 5 second intro clips exported from motion using pro res 4444 1920×1080 that need to go on the disk with the other clips.
Thanks in advance.

A 640×360 heavily compressed source just isn’t going to handle going through a round of compression going to 1280×720. I’d use H.264 rather than MPEG2 but I don’t think that’s going to help all that much.
You might have to look for good upconversion software.

In terms of size can I get it any smaller so I can fit more on a disc and keep quality close to the original. The converted video I made of the source to 1280×720 doesn’t look half bad compared to the original the problem is I can’t fit as much as I would like on a blu ray.
What up-converting software would you recommend I use in this situation?
I just want the video to display half decent on a big screen with no artifacts. It looks fine when I watch it on my TV from my PC, I wish getting it to do the same on a disc was easier.

You can lower the data rate but that lowers the quality.
I like this bit rate calculator.https://www.pimley.net/projects/#bitratepro
