Editing Old VHS tapes 3 weeks, 1 day ago #198274

I had a friend transfer a lot of old VHS tapes to folders on an external hard drive. I now want to import them into the software and cut some out, splice other frames in, etc to create one file of video for each of my kids. This software isn't particularly intuitive and I've spent some time watching tutorials but I can't import any of the folders. They are wvm extensions. When I go to the hard drive and click on a folder and "import", nothing is happening. Any suggestions? I saw that I might need Quick Time? I tried to download that and got an error message. Don't know if that has anything to do with it.

Thanks.

Welcome to the forum.

Unfortunately, there is currently no support for importing .WMV fles in Lightworks. You will need to transcode the files using third party software. Handbrake should do the job for you.

This thread gives suitable settings for Handbrake: www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=166802&Itemid=81

I'm not sure how to know what my old VHS (circa 1980s) frame rate is. I guessed and put something in when I first opened the software. Now I'm trying to import and it's saying the frame rate might be the problem. I don't see where to go to adjust that.

Thanks.

Do you live in a NTSC country such as the USA, if so, set the project frame rate to 30fps.

If you live in a PAL country like Europe set the frame rate to 25 fps.

Please have a look at the Quick Start video before starting.



There is also a Quick Start V14.5 user guide found in downloads > documentation

It appears to me as if that's a continuation of your post yesterday:
www.lwks.com/index.php?option=com_kunena&func=view&catid=67&id=198274&Itemid=81#198274

To find out what frame rate your material has, posting a Mediainfo report can help.

I have merged your two threads into this one. One was really an extension of the other, and keeping the two together maintains context. That can be really important for problem solving.

I agree with briandrys - you are unlikely to need a MediaInfo report. Your media frame rate will be governed by the country in which those VHS tapes were recorded. If that was the UK, Ireland, Europe, Australia, New Zealand, Hong Kong, Macau, South Africa, India or China they will almost certainly be 25 fps. If not, they will be a nominal 30 fps.

However you can find out for yourself. If you have managed to convert to a format that can be imported into Lightworks, create a new project and set the frame rate to "Auto". Import some media and the frame rate will be shown in log mode ("Fixed" interface) or by clicking on the filecard icon ("Flexible" interface).

I have spent a lot of time this morning readying and watching tutorials. I have changed my format from wmv to mp4 with Handbrake, as suggested. I tried to import using 30 fps, as suggested. I'm still getting the error message stating to check frame rate or audio sample rate. I'm not able to figure that out.

Thank you.

What frame rate have you set the project for?

Now, I would need two Mediainfo reports, one from the original footage, the .wmv file, and one from the file converted with Handbrake.

If you don't agree posting information about your media, try 25.

Thanks.

Would you be so kind posting a Mediainfo of the converted file?
