ffmpeg và exr - kênh ZBack không được hỗ trợ

Tôi đang cố gắng chuyển đổi một chuỗi exrs được tạo bởi Maya render thành phim nhanh. Tôi đang chạy ffmpeg trên Windows 7 (64 bit). Tuy nhiên, thời gian nhanh chóng của tôi sắp ra màu đen.

>ffmpeg.exe -y -i path_to_frames\Render_Beauty.%04d.exr -codec copy -c:v qtrle path_to_frames\Render_Beauty.mov

Tôi nghĩ vấn đề này có liên quan đến kênh ZBack trong exrs:

[exr @ 000000000037f680] Unsupported channel ZBack.
[exr @ 000000000037f680] decode_block() failed.

Tôi đã thử chuyển đổi với phiên bản mới hơn của ffmpeg (20170921 - 183fd30), nhưng kết thúc với một thông báo lỗi hoàn toàn khác:

[exr @ 000000000032b120] flags 8 is not implemented. Update your FFmpeg version
to the newest one from Git. If the problem still occurs, it means that your file
 has a feature which has not been implemented.

[image2 @ 00000000003286c0] Could not find codec parameters for stream 0 (Video:
 exr, none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

Bất kỳ gợi ý về làm thế nào để giải quyết điều này?

===== Cập nhật =====

Kỳ dị. Tôi đã chạy một phiên bản cập nhật của ffmpeg đối với một số tệp thử nghiệm (như tôi đã làm trước đó) và nhận được một số thông báo lỗi mới.
