AVI to AC-3 audio FAQ
Why extract AC-3 from AVI?
An audio-only AC-3 copy supports multichannel delivery without retaining the AVI picture.
Can every AVI file produce AC-3?
Only when the AVI source contains a readable audio stream; video-only footage cannot produce useful AC-3.
What should I check in AC-3 after extracting from AVI?
Listen through the AC-3 result for expected duration, channels, level, and synchronization before delivery.
