Video CODEC advice
 

Rather than the usual H.264 codec, a lot of mp4 and webm vids being sent to me report they are using "bipolar" as their codec.

Trying to convert any of these files results in an error or a tiny file (around 6kb). That is local conversion or online conversion.

I use the K-Lite Mega pack of codecs, but the name "bipolar" doesn't exist in it's listings.

Oddly though, VLC media player can play the original files, though trying to upload them to Facebook or Youtube returns an error.

Any video experts here?

I've never heard of bipolar!

What player are you using?

Give VLC Player a go in case that supports it as it is one of the most popular and best.

edit

I see your already tried VLC.

Re: Video CODEC advice
 

Same here. Never heard of that codec. Try uninstalling all codecs, then install VLC, MPC, AC3filter codec and go from there.

Re: Video CODEC advice
 

Start playing the video in VLC and then look at the properties. Might give a clue?

Re: Video CODEC advice
 

I dont think there is such a codec, Ive never heard of it either.

What information does MediaInfo show for them ?

First is the info from Freemake Converter, where it says "bipolar" is normally where H.264 appears.

Re: Video CODEC advice
 

As MediaInfo shows, the Video is AV1, and the audio is Opus.

Re: Video CODEC advice
 

Doesn’t appear on their supported formats list.

Re: Video CODEC advice
 

I have now tried 26 online converters and they all crash, give errors or return tiny 6kb files that don't open, in any format I select.

Maybe it's not the internal codec but the mp4 wrapper?

Incidentally I already have the Win10 codec for AV1 https://www.microsoft.com/en-us/p/av...ot:overviewtab

Re: Video CODEC advice
 

FFMPEG might, but I dont have any files of that format to test.

Re: Video CODEC advice
 

Here is a short one. I need to convert it to AVI for editing in VirtualDub.

Freemake converter describes it as "bipolar", but also that it has no audio.

It opens perfectly in VLC and others, but will not convert or be accepted for uploading to Facebook or Youtube.


It failed....

Ho hum, even this forum will not allow it to be uploaded, "Invalid file" :dunce:

Re: Video CODEC advice
 

I did pm you my email to send one over but you don't seem bothered.

Re: Video CODEC advice
 

zip it up. The forum allows zipped files up to 1MByte and RAR files to 3.9MByte as attaches.

Re: Video CODEC advice
 

Winzip, 7 zip and Winrar all produce zipped files that this site report as "invalid" but within size limits. :(

But if I extract the file, it runs perfectly in VLC.

Second try..
