Video has wavy lines when played on timeline

@JonesVid the OP would not have to use a capture card,  you can use a Digtal8 camcorder, which will read HI8 tapes, and the camcorder (or play back deck) will convert the Analog to Digital via the Firewire, I have done this hundreds of times.  I suspect the OP used this approach.

(edited to add that now ALL cameras do this, you have to check the specs, but there is a healthy list of ones that do just didn't want someone reading this in the future to think every camera did and to confirm the model they have/buying will); 

I still have a Sony Camera I kept for this purpose,  but with lots of luck have not needed it, because I update premier to the latest version as soon as my current work is done - all in on the risk 🙂 

If I ever needed to capture a HI8 again, I would just get one of those analog to SD card captures and avoid the computer to capture.  But fingers crossed I would not want to,  This thread has caused me to remember all the reasons I disliked interlaced footage, and the analog noise.... 

There is not much we can do. The clip runs fine in 25.3 (windows) but your Premiere version is very old and so is your machine.

Might want to transfer footage to a newer Premiere version and machine.

Did you turn off Composite in linear color?

If you get this sorted, you need to change your export settings.

Clip on Vimeo shows horizontal stretching (4:3 stretched to 16:9)

Frame size 864x480 with a par of 1.0 and fields to progressive.

This way there will be no combing (or other interlaced artifacts or incorrect aspect ratio) on a modern digital tv.

On a side note 2023 was the last Premiere version with the Capture feature.

I think FFMPEG also does deinterlace for free if the OP is more aware of that tool.

What I see in the symptoms video doesn’t align to interlacing issues fully unless it has something to do with the playback engine creating a different defect than what would normally be expected.

The fact that its blocking in large groups of rows is different and not expected.  It reminds me of a capture sync and frame rate issue - but this is so far back in my memory banks I am not 100% confident.

If it tweaks anyone’s memory, I was thinking it might be something along the lines of manually selecting 30 FPS for capture, and the playback is 29.97 in this case, and because the user may have had to manually select frame rates they didn’t align.

It’s possible they could use the interpret footage to force a new frame rate to match the captured rate.

I’d like to see the media info of the source files and see how that compares to the sequence settings. However, I suspect when they created the project, they were asked to update the timeline to match and likely said yes (if they said no this is probably the issue).

It feels like a frame rate mismatch to me but can’t exclude interlace playback issues either.

a Sample of the footage used would allow @Ann Bens to test, and I would also.

The OP could post clips from Media info tool to confirm the frame rates of the actual video, but if it was a capture / playback mismatch it would not catch that error with media info.

I would like to have a original clip not a screen recording 

please post computer specs

what devise is going to be used for the video because the export settings are not good

which premiere version and build
