Thank you for reporting. I can confirm the crash with exporting VP8. VP9 and move render without failure. On which windows version do you made the test?

Windows 10 In Linux, I only get a render crash with vp8. vp9 and mov render fine but without alpha. vp8 error: Rendering of /tmp/untitled2.webm crashed [libvpx @ 0x7fffd8203880] Bitrate not specified for constrained quality mode, using default of 256kbit/sec [libvpx @ 0x7fffd8203880] Transparency encoding with auto_alt_ref does not work Git commit ed550ac73f9b1987adcc1367aacba83e369af81e by Julius Künzel, on behalf of Farid Abdelnour.

SUMMARY Trying to render videos with the alpha profiles crashes, although alpha mov will give a video file output. Not only is there no transparency, but most of the profiles don't produce any exported videos. STEPS TO REPRODUCE 1. Create a title clip. 2. Add to timeline. 3. Export as VP8, VP9, and/or Alpha mov. OBSERVED RESULT Rendering crash with no output for VP8 and VP9. Alpha mov will also crash but will produce an export. However, the exported clip has no transparency. EXPECTED RESULT Exported clip with transparency. SOFTWARE/OS VERSIONS Windows: 10 ADDITIONAL INFORMATION Log for alpha mov: mlt_repository_init: failed to dlopen C:\Program Files\kdenlive\lib\mlt/libmltjack.dll ("C:\Program Files\kdenlive\lib\mlt\libmltjack.dll": The specified module could not be found.)
