Fails to import correctly Topaz VAI generated mp4 (both AVC and HEVC)

andreas-georgiou wrote on 8/20/2025, 10:22 AM

When importing Topaz Video AI generated MP4 either H264 (AVC) or H265 (HEVC) Vegas pro 22 (B250) reads the frame rate as 12,800.00 and as such when added to timeline only adds the first few seconds. see attached screengrabs

Also a template of 240fps is somehow loaded, complete mess preventing editing Topaz VAI V 6.2.2 2025 generated files.

any thoughts help?

Please provide a Media Info readout of some of this media which Vegas is having problems importing.

What does Mediainfo say about those MP4's?

Use Media Info program. Topaz generates such rubbish files.

1. Run VirtualDub in copy mode – it should help.
2. Use ProRes in Topaz – but it seems to have bugs too.
3. It's generally best to export to FFV1 in Topaz and recompress to ProRes/H26x in ffmpeg.

The Picel aspect ratio is not correct. I should be 1,0 for progressive videos.

j-T Thanks, they only play properly with VLC media player others fail to play the files also, Pixel aspect ratio would change the size of the image?

I need to run Topaz AI as the footage is AVI 3/4 aspect interlaced it does a very good job in cleaning it up, de-interlacing, de-noising, upscaling etc.

rgr Thanks, I have tried intermediate conversions to correct it but I loose quality.

 

The big question is why is Vegas reading the file as 12,800 fps and when is set to set project to the media settings it comes up with such a weird template?

its only the last few updates that have broken their render codecs I think as it used to work fine in the past despite all the bugs i reported to them.

 

The guys (not sure if there is a team?) are very responsive but they are constantly messing around with the UI breaking parts of functionality instead of focusing on what is important to users IMHO

@andreas-georgiou I would use Topaz to cleanup the final edit made with Vegas and not trying first to cleanup the footage with Topaz and than start editing that footage. With other words, I would use Topaz at the end of the editing stage and not at the beginning.

Thanks 3POINT, I usually do that, but even then clients cannot play the mp4's on their devices as they do not play in a number of windows players including cyberlink media player, power DVD etc. they play fine if one installs VLC free player very odd, so the bugs are in the exported files and not Vegas me thinks.

So my thoughts were that I could import to Vegas then export from vegas as their codec seem more universally playable nowadays...

@andreas-georgiou

I think you should present the problem in the Topaz Video forum.

@andreas-georgiou

You have three fundamentally different problems.

1. Convert 4:3 video to 16:9 format. In this case, you need to crop the 4:3 video.

2. Deinterlace interlaced video.

3 Upscale cropped video to 1920x1080 size.

J-Toresen, thats the beauty of topaz, it upscales to fhd maintaining aspect ratio, it de-interlaces, it de-noises, improves resolution! (like magic) but sucks at exporting in a universally playable format, most windows and smart devices refuse to play it although the free vlc player has no issues (go figure)

I am in discussions with topaz Suport team, send log files etc they are investigating, but not absolutely sure it’s not a vegas issue too? Why does mp4 properties clearly show fps as 25 yet vegas imports the file but somehow thinks it’s 12,800 fps? And when added to timeline only adds a fraction of 1 sec instead of 1.5 hours of video I think there is also a vegas issue somewhere in the depths of its algorithms

A free video VLC player plays the video flawlessly at the correct frame rate etc yet expensive all singing dancing players like cyber link etc do not load or play the topaz exported video

Looking through these posts I see a few have asked for media info from this free utility below but it has not been given. Here is the link to the utility:

Down load the utility and post the output on this forum to provide a comprehensive readout of the media information that Topaz is generating. It may help solve the problem.
