[Jeff Meyer] “Use DNxHD or ProRes.”

[Tim Johnson] “I have tried to follow their specs exactly.”
I don’t think it’s related to the letterboxing issue, but the GOP structure in your export settings is different from the linked spec.

The issue appears to be related to the aspect ratio. Have you tried exporting with square pixels instead if Widescreen 16:9 (1.000)?

The blurriness might be a byproduct of chroma sub-sampling. If so, it will be difficult to eliminate. Try exporting a few frames with 4:2:2 and uncompressed RGB (“None”) codecs to verify.

[Jeff Bellamy] “and 300 fingers crossed”
That’s a lot of fingers! 🙂

If your sequence uses 720×480 anamorphic video, you may want to export a version with square pixels for H.264 playback on computers/web because most media players do not recognize rectangular pixels. Set the export aspect ratio to square pixels and change resolution to the square-pixel equivalent.

The black spots indicate unsafe areas that were keyed out by the Broadcast Color effect. Use the Fast Color Corrector or Luma Curve effect to reduce the output white level to 235 or less. Apply Broadcast Colors after the color correction effects, set “Maximum Signal Amplitude (IRE)” to 100, and change “How to Make Color Safe” to “Reduce Luminance” or “Reduce Saturation.”
Please refer to Adobe Help for more information on the Broadcast Color effect.

Is the broadcast safe filter disabled?

Thanks for posting the images. The block dots are perplexing, but overall the color correction looks straightforward. Your source footage is recorded in Y’CbCr format, which covers a range from approximately -7 to 109 on the Y-curve. Adjust output black and white levels until the Y and RGB curves range between 0-100:
– Disable or clear the effects already applied to your clip
– Insert a new instance of the Fast Color Corrector
– Set Output Levels to 16-235 (0-235 will probably be with this footage, too); Adjust further if required.There are a few ways to increase the brightness of the bride’s face. First try adjusting Input Gray Level on the Fast Color Corrector. If that doesn’t work satisfactorily, use the Luma Corrector to adjust Master gamma or Midtone gamma/gain.
If the black dots still appear, try disabling all effects. Hopefully the black spots will disappear. Turn the effects back on one at a time until the black points reappear.
There are some great tutorial videos on this website regarding Premiere Pro color correction.

Please post a frame shot of the source footage before the effects were applied; I’d like to look at it through the scopes. Also, it would be helpful if you listed the effect settings that were used, or just post a screen shot of the effects panel.

[Evan Thompson] “Is there any free program that can convert without changing dimensions or quality?”
What are the desired dimensions? As long as you use multiples of 16 you should be OK.
Expression Encoder 4 is free for VC-1/WMV, but it does not support DNxHD; use JPEG2000 instead. You can convert DNxHD to H.264 using QuickTime Pro ($30).
