Converting a series of jpeg images to a mp4 video:

ffmpeg.exe -f image2 -r 3 -i %06d.jpeg -r 15 -vcodec mpeg4 -s 352x240 Camera-0.avi

-f image2 => input format
-r 3 => input framerate
-i %06d.jpeg => input mask (files must be named sequencially, with 6 digits. Ex: "000000.jpeg", "000001.jpeg", "000002.jpeg", etc)
-vcodec mpeg4 => video output codec 
-s 352x240 => resolution

The Pi outputs a relatively weak HDMI signal. Some devices may not immediately notice the Pi's HDMI or may not do the negotiation.
Setting the hdmi_force_hotplug=1 makes sure the Pi believes the monitor/TV is really there.
You might also need to set config_hdmi_boost=4 or even higher (up to 9) if your display needs a stronger signal.
If the display is a computer monitor, use hdmi_group=1 and if it is an older TV, try hdmi_group=2.
Do not set hdmi_safe=1 as that overrides many of the previous options.
Using a shorter or better quality HDMI cable might help.
Make sure your Pi's power supply delivers 1A and not 500mA.
If you see a problem with the red colour - either absent, or interference - then try a boost. However it might simply be that the display requires a stronger signal than the Pi can give.
