Audio delay after encoding MPEG-2 (+34ms) - VideoHelp Forum
https://forum.videohelp.com/threads/236589-Audio-delay-after-encoding-MPEG-2-(-34ms)
Audio delay after encoding MPEG-2 (+34ms) 1. Change the target audio bit rate (192Kbps to 384Kbps Mpeg-1 Layer 2). 2. Change the target sample rate (48Khz to 44.1Khz Mpeg-1 Layer 2). 3. Change the target audio file type (from Mpeg-1 Layer 2 to uncompressed Wav). 4. Change the video bit rate (CBR / ...
MPEG-2 - Wikipedia
https://en.wikipedia.org/wiki/MPEG-2
MPEG-2 is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer …
Audio out of sync with MPEG2 - Adobe Premiere Pro ...
https://creativecow.net/forums/thread/audio-out-of-sync-with-mpeg2/
When capturing directly to MPEG-2 from VHS, the audio is sometimes delayed in the final MPEG-2 file. I can re-capture the same video and it will be fine. 2. In captured MPEG-2 files that have no delay in VLC that I put into Premier, the audio is delayed and Premier adds sporadic red frames, and the audio is delayed. 3.
A Guideline to Audio Codec Delay - Fraunhofer

block switching incurs an additional delay: 2 _ _ 2 frame size_ _ long frame size short N −look ahead = + where frame size_ _ long and frame_size_short represents the number of subbands for long and short blocks (e.g. 1024 and 128 for MPEG-2 AAC) [3]. Note: The use of short blocks causes an overhead of side information bits. Also, the lower number of

forms the baseline of development within version 2 of the MPEG-4 audio standard [5] for the work item 'Low Delay General Audio Coding' meeting the requirement for a maximum algorithmic delay of 20 ms [6]. The paper will first provide a general overview over the structure of per-ceptual audio coding schemes and then analyze the sources of coding delay
mpeg - MPEG2 TS end-to-end delay - Stack Overflow
https://stackoverflow.com/questions/16214975/mpeg2-ts-end-to-end-delay
The delay between an encoder and a decoder, on the other hand, is like asking what is the delay between transmitting the data from the source and receiving it in the destination. This is not determined by the data (i.e. the transport stream and the data within such as time stamps) but by the network conditions.

This is only and best way that audio remains in synchronization with video. These timestamps are called PTS/DTS values which are of resolution of 90 kHz clock. Understand that over time clocks skew but since only the exact time is referenced, decoder playout exactly in same time order. Now the major concern remains is that decoder's clock needs ...
