Red Pixelization In Video Preview
on Feb 27, 2013 at 6:55:21 pm

Has anybody seen this before?



I've exported the source video twice now with NO red pixelation, then about 30 minutes in, (the video is 2 hrs total) I get this red pixelation on the monitor preview.

There probably isn't anything wrong with the video itself, just your video drivers or the mpeg decoder used by Encore.

Try building the disc. It should create a disc that does not have that issue.

I tried building a disc. The video needed to be transcoded and it failed. Someone suggested that I transcode first before building, so I'm in the middle of that now. Will post back.

Yes, definitely transcode the video first in Adobe Media Encoder or directly from Premiere before authoring in Encore.

I'm exporting out of Final Cut Pro 7. It's native XDCAM footage encoded as H.264 (I believe.) Transcoding before building the disc gives me the error, "transcoding failed". Hm.

Is this for a DVD or a Blu-ray? 2hrs is a lot of video for a single layer DVD. It will need to encode at roughly 4.5 mbps to fit. If you are editing in Final Cut and delivering on DVD, you can just use compressor to make the mpeg2 DVD file, 4.5 mbps 2 pass VBR.

If this is for a Blu-ray, you can export as ProRes 422, then encode the video in the Adobe Media Encoder for h.264 Blu-ray before bringing it into Encore. In Encore, just import the encoded mpeg2 DVD or H.264 Blu-ray video and ac3 audio (320 kbps).

Hi Jon, thanks for all your help. I have to make both DVDs and Blu-rays. Right now I'm trying to burn the DVDs and I think you nailed it. I am going to encode at 4.5 mbps and see how it goes.

I exported with ProRes 422 overnight and my file size jumped from 30GB to 149GB. I haven't encoded with Adobe Media Encoder yet...just wondering if this sounds right to you?

That's correct. You can save that large file as your HD master or get rid of it after transcoding.

Thanks for all your help Jon, although, I did some more research and decided to take a different approach using Compressor. Here were my findings, (which ultimately fixed both problems including the red pixelization.)

1) Edit your XDCAM video in Final Cut Pro and export as a self-contained movie. Under "Current Settings".

2) Import this video into Compressor.

3) Under "Settings" Apple > Formats > MPEG-2, choose "Program Stream" and drag that onto your clip.

4) Under "Settings" Apple > Formats > Audio, choose "Dolby Digital Professional 2.0" and drag that onto your clip.

5) Now, click the "Program Stream" setting you dragged onto your clip. In the Inspector window, select the "Encode" button.

• File Format: MPEG-2
• Stream Usage: Blu-ray

Under the "Video Format" tab:

• Video Format: HD 1920X1080
• Frame Rate: (whatever you shot in)
• Aspect Ratio: 16:9
• Field Dominance: Progressive

6) Click, the "Submit" button. This will export an m2v (video) file and an ac3 (audio) file.

7) Drag these 2 files into Adobe Encore as your video and audio files and go to town with your Blu-ray authoring.

H.264 is a superior codec, and will provide better quality at an equal bitrate to mpeg2. You can use your method, but for best quality, I recommend h.264.

Thanks Jon, I read somewhere that someone was having problems with the H.264 so I opted for the other method. I'm sure you're correct...when I have more time I will use the H.264.

Thank you for your time.

So just to reiterate/update (in case someone else needs this info:)

1) Edit your XDCAM video in Final Cut Pro and export as a self-contained movie. Under "Current Settings".

2) Import this video into Compressor.

3) Under "Settings" Apple > Formats > MPEG-2, choose "QuickTime H.264" and drag that onto your clip.

4) Click, the "Submit" button. This will export a QuickTime H.264 file.

7) Drag the file into Adobe Encore and go to town with your Blu-ray authoring.
