The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with a different kind of file to confirm that the problem is related to just this file.
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting

Steps to reproduce

When I try to split this video into several clips and encode them with other encoder programs (e.g., Shana Encoder, A's Video Converter), the process does not proceed.

Original video information:
Format: MPEG-4
Format profile: Base Media
Codec ID: isom (isom/iso2/mp41)
File size: 20.9 GiB
Duration: 52 min 49 s
Overall bit rate: 56.6 Mb/s
Frame rate: 59.940 FPS
Writing application: Lavf61.7.100

Video:
ID: 1
Format: HEVC
Codec ID: hev1
Duration: 52 min 49 s
Bit rate: 56.3 Mb/s
Width: 8192 pixels
Height: 4096 pixels
Frame rate mode: Constant
Frame rate: 59.940 FPS
Color space: YUV
Chroma subsampling: 4:2:0
Bit depth: 8 bits
Stream size: 20.8 GiB (99%)

Audio:
ID: 2
Format: AAC LC
Codec ID: mp4a-40-2
Duration: 52 min 49 s
Bit rate: 317 kb/s
Channels: 2
Sampling rate: 48.0 kHz
Stream size: 120 MiB (1%)
Language: English

After splitting, video information:
Format: MPEG-4
Codec ID: isom (isom/iso2/mp41)
File size: 411 MiB
Duration: 1 min 0 s
Overall bit rate: 56.9 Mb/s
Frame rate: 59.940 FPS

Video:
ID: 1
Format: HEVC
Codec ID: hvc1
Duration: 1 min 0 s
Bit rate: 54.3 Mb/s
Width: 8192 pixels
Height: 4096 pixels
Frame rate: 59.940 FPS
Stream size: 393 MiB (95%)

Audio:
ID: 2
Format: AAC LC
Codec ID: mp4a-40-2
Duration: 1 min 0 s
Bit rate: 317 kb/s
Channels: 2
Sampling rate: 48.0 kHz
Stream size: 2.29 MiB (1%)

After splitting, the Codec ID changes to HVC1, but I am not sure if that is the cause of the problem.

When I split the video using another splitter program and then use Shana Encoder or A's Video Converter, the encoding works properly.

Expected behavior

After splitting the video with the LosslessCut program, the Codec ID should remain HEV1, but it changes to HVC1.

Actual behavior

After splitting the video with the LosslessCut program, the Codec ID should remain HEV1, but it changes to HVC1.
