HD video to SD DVD
Quick question. I have just shot a video on my 7d in 1080p (24fps). I convert to prores 422 using the EOS plugin for FCP. The edit is complete. I then send to compressor.
From here I am confused. The last time I did this I used
“standard 90 minute high quality preset”.Once the file was compressed, it opened it in DVDSP, made all my menus, etc.., and burned to disc.
I noticed the aspect was slightly off. It just didn’t look quite right. Seemed like the image was slightly large (almost like full frame) even though I made sure to set the aspect to 16:9.
Do in need to make it letter box? Pan and Scan?
Any help would be greatly appreciated.
Thanks!

DVDSP should read the file’s aspect ratio correctly as should Compressor.
Chose the compressor preset that best fits your program length.
In DVDSP you want letterbox mode for the display:

It should, but when I select Letterbox, it does not keep a true aspect ratio. By selecting letterbox, should I see the black bars at the top and bottom of my TV?
Like I said, its only slightly off. In some shots, the heads are slightly cut off at the top and the image seems like its a little stretched.

That sounds like the DVD player settings or the TV settings.

You really don’t want to select letterbox. When you simply use the Compressor DVD Settings, what it’s creating is a file that will play full screen on a 16:9 HD tv or letterbox on a standard 4:3 TV.
If you’re losing part of the image in full screen mode on an HD TV, well this is normal. That’s why we have Broadcast Safe and Title Safe markers to work with because you’re going to lose up to 15% of the outside of your image depending on the TV, the DVD player and when it goes out over broadcast, the broadcaster / cable casting company.
TVs do not show 100% of your image, there’s always a crop.

Hi,
similar issues.
SONY – HDR-SR5E ( HD handycam )
FCP – 6,0,6
Imac 20″ aluminium – Core 2 Duo – 3Go RAM – 1 x 500Go HDD external drive.
I am using FCP to list & transfer my holiday clips to the HDD, then drag them all down to the timeline,
add transitions & whatever, save as autonomous QT file. The QT file goes into compressor which produces the .ac3 and .m2v output using 120/150″ best quality parameters ( not .aiff )
These go into DVD pro to burn a DVD suitable for a home DVD player
The results are good, but I get crenellation when panning over fixed images. Steady shots are fine, but as soon as there is any movement, the crenelation reappears.
I should add, my TV is an old CRT model – could it be the refresh rate is just not high enough to avoid crenellation, and it’s time to go for a new LCD 200Hz model?Thanks in advance for your sagacity
Lance
