Black screen after time remapping - please, help!

[timofax]

I have about 40 files from car DVR. And I need make a long movie to show my trip in short time and make an accent of viewers to some moments. So I need to raise speed to 1000%, but in some moments reduce it to 50%. First, I put all videos to my timeline, and after it I make "clip from sequence" - it's, I think, best way to edit long video. After this, I set my time remapping keys, and lift line to 1000%. And from this moment my video playing only till certain point. After this point - black screen. If I reduce speed to, for example, 200% - everything is OK. What I'm doing wrong?

By the way, if it's important, I have strong machine - 3950X, 64RAM, all SSD, 2080Ti.

I work around to try for now would be to do a render and replace. Then apply the speed ramping to the clip.

I'm guessing that the source clips have a variable frame rate which Premiere has problems with...

Use media info to check to see if your source clips have a variable frame rate

If they do, use handbrake to convert to a constant frame rate.

Post back if you have any questions about workflow using these 2 programs

Thank you, but I arleady checked this. There is same bitrate, same resolution, same file format etc. And... CBR. All files has been recorded in 4 hours on one device, one SD-card, no one setting has been changed while recording. Now I resolved this promlem trough render all files from timeline to one .mp4 file, after this I use this file like  like source and have no promblems. Of course, it was longer, but effective :))

You want Constant Frame Rate, not Constant Bit Rate.
