No luck with Compliant MPEG-2 streams


Tarkin

Question

Hello everyone.

 

I have been totally unsuccessful at making a compliant MPEG-2 file from any of our encoders. It would save a lot of time (and video quality) if I didn't have to transcode everything twice.

 

The source video is 720p/30 video that was imported into Final Cut Pro 5.1.4 for editing and exported from there as an animation compressed quicktime to work with the PC based encoders and as a timeline native quicktime movie for Compressor (the video was edited in 720p/30). We are then upscaling the video to a 1080i/29.97 within the encoder.

 

I looked at the sticky thread for making compliant files and found the Compressor settings and the Vegas output information located there and since we have both of those programs, I gave it a shot. This is what I have my encodes set to:

 

Compressor

 

File Extension: m2v

Type: MPEG-2 video elementary stream

Video Encoder

Format: M2V

Width: 1920

Height: 1080

Pixel aspect ratio: square

Crop: None

Frame rate: 29.97

Frame Controls:

Retiming: Nearest Frame

Resize Filter: Linear Filter

Deinterlace Filter: Line Averaging

Adaptive Details: On

Antialias: 0

Detail Level: 0

Field Output: Same as Source

Aspect ratio: 16:9

Field dominance: Top first

Average data rate: 21.1 (Mbps)

1 Pass VBR enabled

Maximum data rate: 25 (Mbps)

High quality

Best motion estimation

Closed GOP Size: 15, Structure: IBBP

--------------------

Vegas 7 (Mainconcept MPEG-2 Encoder)

 

1080i BluPrint Compliant (Upper Field First)

Have produced both open and closed GOP sample files

CBR 25Mbps

Saved as elementary streams

ALL OTHER SETTINGS ARE PRESETS

--------------------------

 

Neither of these video files will import into DVDit Pro HD as a compliant MPEG-2 file. We have tried several variants of these settings as well with no luck.

 

Can someone tell me what might be going wrong here? Encoding setting changes? Is there a setting within DVDit Pro HD that needs to be changed other than switching it to a BD-25 disc? We have also messed with the transcoding settings in DVDit Pro a few times to see if that affected import at all.

 

The ultimate goal is to find some setting that will work for our StreamZ encoding system, which is a lot faster than any of the other encoding machines or the authoring system and has hardware to assist.

 

Any help in this matter is much appreciated. Thanks!

are you sure they are not importing as legal? the warning has 3 different possibilities:

 

- not DVD legal

- not BD legal

- not DVD or BD legal

 

if you import 25mb MPEG-2 you will always see a warning. If the video is Blu-ray legal, Blu-ray will not be included in that warning.

Ahhhh. ok. After going back through and verifying the error exactly, we do have a few files that do not say BluRay when the error comes up. I guess we got so used to seeing it that we missed the change when we got a working one.

 

Thank you very much for your help!
