I got a frame rate under 1 and can't seem to get ffmpeg to stamp the time code
Doesn't work
ffmpeg -start_number 0 -framerate 32 -y -i "f0_t%d_i0_ch1_c0_r0_z0_mqdic.jpg" -vframes 32 -vf "drawtext=fontfile=DejaVuSans.ttf:timecode='00\:00\:00\:00':timecode_rate=0.28571:fontcolor=red:fontsize=64: box=1: boxcolor=0x00000000@1,setpts=PTS" -pix_fmt yuv420p -c:v libx264 "part9_dynamics_slower_sampling_z0.avi"
with an error
[Parsed_drawtext_0 @ 00000283dbab5f00] Timecode frame rate must be specified
[AVFilterGraph @ 00000283dbab58c0] Error initializing filter 'drawtext' with args 'fontfile=DejaVuSans.ttf:timecode=00\:00\:00\:00:timecode_rate=0.28571:fontcolor=red:fontsize=64: box=1: boxcolor=0x00000000@1'
Error reinitializing filters!

Works as expected
ffmpeg -start_number 0 -framerate 32 -y -i "f0_t%d_i0_ch1_c0_r0_z0_mqdic.jpg" -vframes 32 -vf "drawtext=fontfile=DejaVuSans.ttf:timecode='00\:00\:00\:00':timecode_rate=1:fontcolor=red:fontsize=64: box=1: boxcolor=0x00000000@1,setpts=PTS" -pix_fmt yuv420p -c:v libx264 "part9_dynamics_slower_sampling_z0.avi"
In one case timecode_rate=0.28571
and in the other timecode_rate=1
So, how do I stamp in the correct, 0.28571
frame rate?
