Hi all,
I am getting desperate now. Very strange observation with both versions VEGAS Pro 22 B 122 an 0.93. I have a longer travel video made with my DJI pocket 2 camera. Length of the video is approximately 1h. For the rendered video (using voucoder) from minute 30 I have no more audio. I made a next test with rendering just the audio part as wave file only with the same result: No audio for the last 30 minutes.
Was first thinking that this is an issue with my footage. Made further tests, but now focusing on the audio track only (i.e. neglecting the video and rendering as wav audio ony (under render as... Wave Microsoft, 48.000 Hz; 16 Bit).
Now I selected a loop region of a few seconds length in the latter half of the full video (the audio in this region was certainly lost during my full rendering tests). And surprise: The audio in the rendered loop region as wave file is there!
So, next test: I rendered the complete second half of the audio part (minute 30 to 60, again wave file only). -> No problem at all, audio is fully available.
That is really strange, do you have any ideas what causes this issue ??
Thanks and best greetings
CeSa
