Delivery Specs for online streaming site
I have been tasked with converting videos for delivery to a specific streaming video site. There are some settings that I don’t exactly know how to match since the language is a bit different than the Vegas render settings dialogue box. I hope someone can tell me how to achieve these settings in Vegas.
This is an .mpg2 and these are the settings I’m unsure about:
-Chroma Format: 4:2:2
-GOP Structure: I-Frame Only (Can this be achieved by simply checking I Frames only under the 3 different specs they appear?)
-Profile/Level: 4:2:2p@HL
-Color Space: YUY2
-Mux Type: Transport Stream -

[Sam Caino] “-GOP Structure: I-Frame Only (Can this be achieved by simply checking I Frames only under the 3 different specs they appear?)”
No, I don’t believe that Sony Vegas allows you to create an I-Frame only MPEG2 file with the MainConcept encoder.
[Sam Caino] “-Profile/Level: 4:2:2p@HL “
Set both the Profile and Level to High and then on the Advanced Video tab set the Sampling format to 4:2:2.
[Sam Caino] “-Mux Type: Transport Stream”
On the System tab make sure that the Stream Type is set to Transport.
The lact of I-Frame only may be a show stopper. See if they will accept Sony MXF files and then use the HD422 1920×1080-60i 50 Mbps template. Otherwise you may need to find another MPEG2 encoder.

Thank you for the information. Another mpeg2 encoder is a possibility. I could still use vegas for my edits and utilize the no-compression render. Can you recommend another mpeg2 encoder?
-
Yes you can still use Vegas for editing. I wouldn’t buy an encoder just for this. I would try and fine another format that they will accept. I believe the Adobe Media Encoder can do this but Adobe doesn’t sell it separately. You have to buy their whole suite.

I found settings that result in gSpot saying the clip is all I Frames. Set I Frames to 1 and B Frames to zero. Under Advanced Video – make sure only I Frames is checked on all 3 rows.
However, I am now having trouble rendering an .mpg2 at 1920×1080 80Mbps. Any clip longer than 10 seconds gives me an error message. Can anyone begin to help troubleshoot this issue?

[Sam Caino] “However, I am now having trouble rendering an .mpg2 at 1920×1080 80Mbps.”
The MainConcept MPEG2 encoder maxes out at 60Mbps so you won’t get 80Mbps.
[Sam Caino] “Any clip longer than 10 seconds gives me an error message. Can anyone begin to help troubleshoot this issue?”
Perhaps if you told us what the error message is.

Sorry John, a little frazzled with this one. I’m usually better about communicating on this board. Here’s the error:
“An error occurred while creating the file. The reason for the error could not be determined”
I think you answered my question though. If the encoder maxes out at 60, there’s no way I can meet these specs in Vegas. However, any additional input would be, as always, appreciated. Perhaps I can use frameserver to export the project to another encoder? Can you recommend one?

Where did the requirement for 80Mbps come from? That is insanely high. Especially for streaming. We only deliver 50Mbps for creating HDCAM tapes for submission to PBS. That doesn’t sound correct. Also, I’ve never heard of a site that only accepts one format. Did you ask if you can deliver MPEG2 in an MXF file?

The specs are correct. The client is the biggest name in streaming movies and tv. I don’t think I can achieve them with an .mxf either. I may not have mentioned this needs to be a transport stream.
So let’s say these specs were rigid – what would you do?

Ask the client what their other proviers use. Then go buy it.
