Transcode Question
Hello,
I recently have switched over from using Impression DVD-Pro, (a Pinnacle product) to Encore. The Capture Card I am using to digitize the video is a DC2000, (another Pinnacle product) which captures DVD complient MP2 files. My question is, why is it that Encore thinks my captured Video/Audio files are not DVD complient and need transcoding?
Any help would be greatly appreciated.
Thanks in advance…
Devon

Devon,
Could you check an MPEG-2 file made with the DC2000 with Bitrate Viewer and post the following info (found in the lower right):
Stream type:
Resolution:
Aspect ratio:
Framerate:
Nom. bitrate:
VBV buffer size:
Chroma format:
DCT precision: -
Hey,
Thanks for the quick response.
Stream type: MPEG-2 MP@ML VBR
Resolution: 720*480
Aspect Ratio: 4:3 Generic
Framerate: 29.97
Nom. bitrate: 6006000 Bit/Sec
VBV buffer size: 112
Chroma format: 4:2:0
DCT precision: 10 -
Devon,
All the parameters you posted are DVD compliant. I half expected the DC2000 MPEG-2 to be 704×480 instead of 720×480 which would force Encore to re-encode. But I don’t see anything Encore could object to.
Are the DC2000 files multiplexed (audio and video) or are they elementary (video only) streams? If they are multiplexed, the audio is probably MPEG-1 Layer II and Encore’s transcoding may be only for the audio part, not the video.

Hey RK,
The DC2000 captures the files seperately. The audio file is captured as a .wav file.
Rate: 48000Hz
Format: 16 Bit stereo
Uncompressed
Interleave: 1/2 SecondIf the audio needs transcoding, I don’t really mind. Audio only takes a moment, but waiting for video transcoding takes a very long time. (8 minutes for a 3 minute clip)
If you have any other ideas i’d love to hear them. I’m currently stumped.
