Media Convert - PCR/PMT Period consistency

0

Hi. Is possible to generate a TS file with consistent PCR/PMT Period? Currently I am setting "PCR control" = CONFIGURED_PCR_PERIOD, "PAT interval"=100, "PMT interval" = 100, and "Max PCR interval" = 100.

However, the transcoded video file has the following PCR period. 97 ms, 97ms, 62ms, 34ms, 99ms, 95ms, 84ms, 12ms, 97ms... 96ms, 85ms, 11ms

Thanks

Thank you for the clarification. I hope AWS can add new optino/feature to force a consitent PCR/PMT interval in the future.

Thanks.

Hello

Currently, mediaconvert has no option/feature to force a consistent PCR interval. it only has the ability to set the maX PCR intervals as you has tested it out. From the output test you had, i reckon you are using a VBR/QVBR And the specification on Measurement and analysis of the MPEG-2 Transport Stream ETR 101 290 states in section 5.2.2 that PCR Accuracy tests should only be performed on constant bit rate transport streams.

Hope it helps!

Hi. Thank for your answer. I am using the MPEG-2 TS Container Bit Rate Mode to CBR (Constant) and CBR for Video ES Bit Rate Mode for my preset. I am not expecting a consistent PCR period interval for MPEG-2 TS VBR Bit Rate Mode.

Thanks.

Hello Thanks for the update and clarification. For CBR mode , unfortunately, mediaconvert still has no option/feature to force a consistent PCR interval.
