Hello, I'm having a similar issue like some other posts I have found. See below for a list of references.
I have a video that was recorded with a client's phone that I'd like to enhance. It seems like she recorded the video with very low resolution, so the video is extremely blurry and small.
While googling to determine the best way to make the video resolution more clear, most everything recommends Premiere Pro, which is what led me to this problem. I am following a youtube video on how to enhance the resolution (https://www.youtube.com/watch?v=Huzza5rW90o) and after importing the video, am left with audio that is distorted (slowed down and very low pitch?).
I have installed MediaInfo and have the details about the file:
General MPEG-4 (QuickTime): 2.63 MiB, 3 min 58 s 1 Video stream: AVC 1 Audio stream: AAC LC SBR Duration: 3 min 58 s Overall bit rate: 92.2 kb/s Encoded date: UTC 2021-03-27 13:49:03 Tagged date: UTC 2021-03-27 13:49:14 Writing library: Apple QuickTime
Streams Video: 64.0 kb/s 224*128 (16:9) at 15 FPS, AVC (Main L1.1) (CABAC / 2 Ref Frames) Core Media video
I'm not an experienced video/audio editor so all of this is like speaking Greek to me. I have tried following the suggestions in the other posts I've found with no success.
The last thing I tried was converting to H264 with VLC and reimporting. While this did fix the audio distortion, now the audio and video are out of sync. I'm looking at trying to convert the audio to MP3 and separating the video, just not sure if this is the solution or if there is a better alternative.
Any feedback is appreciated! Thank you for the opportunity to learn something new!
