Default Contrast and Brightness for MP4 and DVD

I must be missing something basic. I have my completed edit in EDIUS and I have used the vector scope to assure that I'm not blowing out the whites (over 100%) or crushing the blacks (below 0). Visually it looks great on the overlay and on my TV monitor driven by my HD Spark. I change the Project settings to standard def. and create a DVD. Play the DVD (on that same TV monitor) and it's dull, lacks contrast.
Same thing when I leave the project settings at 1080 and create a GV HD fine file, and feed that to Handbrake to create an MP4. The MP4 looks bright and contrasty played by Windows media player on my editing computer, but not on another computer or on a smart TV.
What am I doing wrong? Why do I not have good brightness and contrast on my distribution media (DVD and Flash Dives) ? Makes no sense to me.
After further thought this has got to be the display adapter settings on my editing computer. I am surprised that these would effect the image through the HD Spark, and that the Vector meter is apparently measuring based on those settings. Any other ideas?

No, changing display adapter settings does nothing to the image displayed in EDIUS. There must be a setting in EDIUS that I am missing.

Sounds like something is adding an additional North American NTSC 7.5IRE setup/pedestal. Pedestal is usually only valid for analog signals. How are you hooked up/monitoring the DVD versus the spark card? Are your monitors (both computer and tv) calibrated or even adjusted by eye to show colour bars correctly?

I'm not familiar with the spark card, so I can't comment on any settings related to it.

Interesting ideas. Editing system is busy generating a new MP4, but I'll look for setup when it's through. Long time since I adjusted for color bars, Guess I'll look at that too. Still it makes no sense to me that EDIUS sees and displays it one way (good brightness and contrast) but outputs it to DVD and flash drive all washed out. The IRE idea is a good one.

Agreed, it should be consistent, but that's what making sure your monitors are adjusted for will hopefully help with.

The 7.5IRE thing, as I mentioned, is related to analog signals, so if your DVD is hooked up analog, the player is probably adding the setup/pedestal.

be sure to play the DVD in a Blu-ray player connected to smart TV via HDMI

a standard DVD player connected via analog cables to a smart TV will give you nothing but unwatchable rubbish

also, make a short test of burning a DVD direct from HD timeline

For the record, both my DVD players are Blu-ray players connected to the TV's by HDMI cable. I will try burning a DVD direct from the HD time line. Right now I'm making contrast/brightness adjustments and writing these to MP4's. When I get one to look good on my TV's I'll go into production and worry about system adjustments in the near future. I have 65 customers waiting for my output. Please let me know of any further ideas. I want to fix this.

I have a feeling that you don't have correct settings when you switch to SD

Can I see your SD settings you used when you got the bad DVD

Have you tried to rip the video from the DVD, drop it on a SD timeline and see what the waveform/vector scope say about the ripped file?

Does your monitor allow/retain different picture settings for different sources?

To avoid some wrong settings on TV input connect the DVD player to the TV input where the spark is connected to.
You could also try using a different DVD player on the TV spark input to test, just to be sure.

Doesn't sound right to me that you have to adjust image (a lot) going from HD to SD...

Swap hdmi cable while you're at it
