Hi Jak.

We have gone through al this before. Any export is a re-encoding and compression of the file being exported unless you are encoding to a lossless format , but those claiming to be lossless only claim you won't see a difference. Microsoft abandoned WMV in 2017 as far as I know. It can cause colour shift problems if the file is ever exported back to another format. Any true lossless format normally produces files far larger than the original.

Movie Edit Pro Plus upwards does support both imported WMV files and can export to WMV if you wish. Just use the normal export functions and use the drop-down list to chose the export file type you want.

From the third image on the right, in the shown drop-down box, you will have to set your settings from there.

What to choose I have no idea. I personally don't like working with WMV or WMA files and try to avoid them.

Any conversion of video from/to dissimilar codec involves re-rendering and potential loss of quality.

MEP has Batch conversion function which can do this - File, Batch convert and follow through the dialogs

The downside of converting to, for example WMV is that many formats are not universally accepted particularly for mobile devices, where you usually have to install 3rd party software capable of playing the video filess, whereas for example the universal mp4 (h.264) is played out of the box.

What does the batch convert do?

@jak.willis

Exactly the same a I showed above but you can select multiple files to be done at once.

You still have to deal with the dialogue boxes and settings I showed earlier.

Thank you for the screenshots.

So you can’t convert from one format to the other without re-compressing and losing some quality?

@jak.willis

No, it can be done (Not using WMV) but the resulting files are huge and impracticable for normal use as they don't play well or even at all once finished. The only time I see it done is by some YouTubers who can't avoid having their videos being compressed again on uploading to YouTube, so they put up a copy that's been edited but not compressed. It's really only practical for professional use. 15 minutes of footage can produce files of over 500GBs and that is definitely not in WMV format but something like Grass Valley's HQX format. But you need a seriously powerful machine to even contemplate handling that type of editing let alone the cost of the supporting hardware.

We've been here before.

It is possible but not normally at a consumer level and it needs to be using specialist software and hardware.

WMV has a smaller colour pallet than most other codecs and hasn't been updated since 2017. Microsoft named it lossless but it is far from lossless. When it was introduced to compete with RealPlayer, and monitors and graphics cards could not produce the colour range they now can, it was fine. But it hasn't been updated for a while as it's been effectively dropped by Microsoft as their business model changed, and is showing its age. I think the only reason for its inclusion is there is still a lot of old material out there. I see no practical reason to use it.

. . . . So you can’t convert from one format to the other without re-compressing and losing some quality? . . . .

In general no, as I said above any conversion of video from/to dissimilar codec involves re-rendering, however there are exceptions eg:

MOV 1920 x 1080 h.264 converted to MP4 1920 x 1080 h.264 can be done with no loss of quality - this is just a container format change.

Is there a way to only change the container in MEP?
