Convert GoPro photos to timelapse video using ffmpeg CLI.

convert.sh

#!/usr/bin/env bash

# -r 60: 60 FPS
# -y: rewrite output file
# -start_number 11555: first frame number
# -i 'G%07d.JPG': file format
# -vf "crop=h=2250": video filter to crop input frame height from 3000 to 2250 (which will be eventually downscaled to 720)
# -c:v libx264: video codec x264
# -crf 20: x264 encoding quality (less = better)
# -s 1280x720: output size

ffmpeg -r 60 -y -start_number 11555 -i 'G%07d.JPG' -vf "crop=h=2250" -c:v libx264 -crf 20 -s 1280x720 output.avi

Some tips on converting VHS to digital.

Software

• K-Lite Mega Codec Pack
• VirtualDub (32-bit version is preferable because of better compatibility)
• LAME MP3 Encoder
• macOs: brew install ffmpeg

Hardware

• SONY SLV-SE620
• EzCap as USB 2861 (DirectShow)
• SCART-3RCA cable (switch to OUT on SCART end)

Audio capture settings

• Check Audio → Enable audio capture
• Uncheck Audio → Enable audio playback. Audio playback may significally slowdown your video capture rate
• Adjust raw audio capture rate to something like 48 KHz 16 bit per second.

🍺 This saved me a lot of time!

This code snippet was very helpful. Thanks a lot. There is only to note that the conversion for mac doesn't quite work that way. The files are not readable after creation.
Adding the parameter -pix_fmt yuv420p solve the problem.
