| CONVERSION TYPE 1 = 'CONFORM' / keep # of frames |
|---|
|
- The video speed will slow down by 4.00%
- As a result, the audio will sound lower
- To correct the audio: pitch up by 4.17% (0.71 semitones)
- Audio correction:
sox INPUT.wav OUTPUT.wav tempo 0.960
- Duration of output = 62.500 sec (
01:02.500- 1500 frames) |
| CONVERT TYPE 2 = 'INTERPOLATION' / keep # of seconds |
|---|
|
- # frames of output = 1,440 frames (60.000 sec)
- Naive conversion: drop a frame every 25 frames
- Since the total duration does not change, the audio can be kept as-is.
