VSP 2021 Problems Saving/Rendering MPEG2 Files

[plasmavideo]

Before I open a ticket with Corel, I'd like to know if my experience is unique to my system.
Create a project with any kind of media. Render the project as MPEG2 for DVD or any other form of MPEG 2.

Files I create have a vertical white line (actually a broken line of tiny rectangles) along the left hand side of the video.

It matters not the source media or the bitrate or frame/field type of the render settings. It also matters not if any hardware optimizations are turned on or off.

Thanks for any input.

Yes I can confirm that i see a light coloured line to the left of the frame

I tested using 2018 2019 and that was clear
I also checked 2022 and that also shows the white line
I tried deselecting Smart Render with no improvement

I also noticed that using the Mpeg2 on a new project did not activate the Messages to match the project which seemed unusual
I'll double check that?

Also from Share the option for Same as First Clip is not available, also very unusual.

I haven't made an mpeg2 in a long time. However, I remember that I used to always get a greenish line down the left hand side of the rendered mpeg2. Mine were always destined to be made into DVDs. When the DVD was made, the line was still there, but not visible on the TV or other screen because it was outside the display area as seen on the screen. So I am wondering in this case whether the mpeg2 has been made into a DVD and whether the line is still visible when the DVD is played on a TV or other screen...

It can't (?) be the OS - with 3 posts each with a different windows version reporting similar response, that seems unlikely.
And now a 4th post (me) with similar effect; not a white line, but a column of v small off-white/lt grey rectangles. What I did to verify . . . .

I have a 3 min vsp created in 2021 using 1920x1080 mp4 clips that I rendered to mp4: no issue or effect of the type reported in the resulting file.
So I trial rendered the same vsp (unchanged: opened it in CVS 2021, chose share and render to mpeg-2), and after the render completed, played the resulting mpg file back in 2021 (preview and full screen), and VLC.
The effect is there in the rendered file at the extreme LH side of the image, but noticeable only in the full screen presentation (VS and VLC), even then only with a light or variably coloured background. Part of the file used a grey full colour background, and against that, the effect was not noticeable. But with a cloudy or garden style background, it's very obvious. Particularly so when playing in VLC.

As a further test, I loaded the unaffected mp4 version of the rendered vsp, and re-rendered it as an mpeg-2 file. The effect was there in the resulting file. So it's clear that the process cause is the choice of an mpg render result. Choosing a different result, eg mp4, and the effect is absent in the resulting file.

Getting Corel to fix this in 2021 would be unlikely (unlike some of their competitors who will support ie issue fixes for a product even if superseded up to 18 months after release, Corel only issues bug fixes for the current product, and mostly for the period 6-9 months after release) unless there are a lot of similar reports. But since Trevor reports it's in 2022, there's a chance that bug report for 2022 might get some response.

A few more tests seem to indicate using Interlaced Lower Field First which would be used when source video is DV-Avi seems to be clear
Using UFF or Frame Based shows the line

I have since tested 2020 which appears ok
Reported as Bug 0921

Thanks for confirming, everyone. I still need mpeg2 for DVDs, as I get requests for them occasionally. Yes, it is a line of tiny rectangles that I see.
I don't see this in any other rendered formats so far. Also, besides DVDs, I sometimes smart render existing mpeg2 files or generate high bitrate MPEG2 files as intermediate formats for use in other other edit apps.

I thought I had tried LFF, but perhaps I didn't. Not too helpful, though, as UFF is the standard I've consistently used, even for rendering mpeg2 from DV sources to keep field orders consistent when editing multiple source formats on a timeline.

I never installed 2020. Perhaps I will, as 2021 keeps crashing virtually on every project. Older versions were hit or miss on smart render and handling of various formats and all presenting with strange quirks.

I need stability, not endless new features. VSP does some things very well for my needs, but consistent performance is lacking. I just was looking at a clip in preview, doing nothing but playing when wham, bam crash. Ran chkdsk and SFC, no problems found. My system seems stable on other editing apps, but I'll investigate further.

Thanks again for confirming the bug. Trevor, do I understand that you have reported this?

Dv-Avi files use Lower Field First, some years ago Video Studio defaulted in using LFF, after introduction of HD they changed that so UFF was used as default for its templates / profiles.

If your source files use LFF then you should use that for your output video, changing from Lower to Upper will show as jagged edges within the video.
However I believe you are mixing interlaced types if so then you may be best to render to Progressive aka Frame Based which should avoid the jagged edges. You can create your own profile to achieve that.

Yes I did report this issue, informing the Video Studios development team bringing their attention to this post.
I also think you should contact Corel support although their first advice will be to re-install.

As for the line I doubt we will see that when playing the DVD on our TV due to the overscan effect.
