此项目在本电脑上交付面板内渲染导出时，软件频繁在中途闪退，无法正常输出视频成片（通常是在进度到约5%时软件无响应、之后闪退；亦或是直接闪退。此项目曾在顺利输出过一次成片、此外有进度达到较高水平后再度闪退的）。此项目在时间线上预览时基本正常（有时会随机偶现部分素材会在播放时闪烁红底“离线媒体”字样）。
基于其他项目输出均正常，考虑应当是当前项目本身的问题而并非完全是软件问题，仓促中时间线非常混乱。软件未向我直接提供问题所在，个人也无法排查出结果。
恳请各位帮忙排查此情况的发生原因，以便我未来规避此现象再度发生，非常感谢。

*采取过的措施：
>升级软件版本（studio 18.1.2→studio 18.5 beta2）
>迁移素材位置、重新拷贝拍摄与下载的素材重新链接
>重装、降级显卡驱动
>在BIOS中关闭CPU及显卡的超频
>调整分辨率、质量、格式、编码方式、渲染速度等
>将全部内容复制到新时间线、新项目
>删除时间线上所有来自第三方的文本效果等
>将时间线上内容全选新建复合片段，开启渲染缓存，并在交付页面选择“使用渲染缓存图像”（渲染缓存正常，但在输出时提示xxx.dvcc未能被正确解码。请检查此片段是否仍旧可以在驱动器上正常访问。）

As this is an English forum, please translate your posts first and then post.

for this first time, i have done this using google.
======

When this project is rendered and exported in the delivery panel on this computer, the software frequently crashes midway, and the video cannot be output normally (usually the software does not respond when the progress reaches about 5%, and then crashes; or it crashes directly) .This project once successfully output into a film, in addition, it crashed again after the progress reached a higher level). This project is basically normal when it is previewed on the timeline (sometimes some clips will flash red background "offline media" during playback).

Based on the normal output of other projects, it should be considered that the problem of the current project itself is not entirely a software problem, and the timeline is very chaotic in a hurry. The software did not directly provide me with the problem, nor could I personally troubleshoot it.
Please help me to find out the cause of this situation, so that I can avoid this phenomenon from happening again in the future, thank you very much.

*Measures taken:
>Upgrade software version (studio 18.1.2→studio 18.5 beta2)
> Migrate the location of the material, re-copy the shooting and re-link the downloaded material
>Reinstall and downgrade graphics driver
>Turn off overclocking of CPU and graphics card in BIOS
>Adjust resolution, quality, format, encoding method, rendering speed, etc.
> Copy everything to new timeline, new project
>Remove all text effects from 3rd parties etc. on the timeline
> Select all content on the timeline to create a new compound clip, enable rendering cache, and select "Use rendering cache image" on the delivery page (rendering cache is normal, but it prompts that xxx.dvcc cannot be decoded correctly when outputting.

Please check this clip whether it is still accessible on the drive normally.)
