What are the best specifications for Instagram videos?

Question

Video

Good afternoon, men!

• Can you please tell me the best way to export from Adobe Premiere Pro to upload videos to Instagram?
  
• What parameters to observe in export?
  
• What is the best way to upload videos to Instagram? Maybe the quality of uploaded videos will be better through the advertising account (if it's possible).
  

(My observations: I often download video files from instagram, as a rule, such files have a resolution of 640 pixels in width, file format: mp4)

Answer 1

Here is what Instagram itself writes for IGTV:

Videos must be in MP4 format.
The aspect ratio for vertical videos is 9:16 and for horizontal videos it is 16:9.
The minimum frame rate is 30 fps. The minimum resolution is 720 pixels.
The maximum size for a video shorter than 10 minutes is 650 MB. The maximum size for videos shorter than 60 minutes is 3.6 GB.

Here is another recommendation:

Format: MOV or MP4
Audio codec: AAC, 48khz sample rate maximum, 1 or 2 channels (mono or stereo).
Video codec: HEVC or H264, progressive scan, closed GOP, 4:2:0 chroma subsampling.
Frame rate: 23-60 FPS.
Picture size:
Maximum columns (horizontal pixels): 1920
Minimum aspect ratio [cols / rows]: 4 / 5
Maximum aspect ratio [cols / rows]: 16 / 9
Bitrate: VBR, 5Mbps maximum
Duration: 60 seconds maximum, 3 seconds minimum
File size: 100MB maximum

Pay attention to the "standard" permissions that Instagram expects from you. If yours are different, they will be shaken.
