What is the difference between "Video Cutter", "Video Trimmer" & "Video Cropper"?

Video Cutter – usually refers to the traditional scissor or knife tool on VES. With cutters, you can basically cut up your video timeline precisely at whatever time you want. Video Trimmer – Usually refers to a tool that allows you to edit the duration of your video by adjusting both ends of the timeline. Video Cropper – This usually refers to a tool that allows you to adjust the visual size of the video, the aspect ratio or remove unwanted visual edges on the image itself. Usually, you’re cropping the aspect ratio of your video display to, for example, make it square (1:1) or 4:3 etc. This has nothing to do with the timeline.

How do I select a pre-defined preset for resizing?

Simply just click settings and select your preferences from a dropdown menu right under the “size” option.

Love this platform for captioning videos. Replaces Spoke and ChopCast for me. I would like to see a "search and replace" feature for changing caption text spelling as it phonetically picks the sound of a word but sometimes brings up poor spelling.

A global "search and replace" change would speed up the software and make your captions sparkle even for more complex topics.

I'm doing a voice translation of the bible and many of the names are spelled differently etc.

Still, this application does handle a need I have been looking for and I'm very glad I got in on a lifetime plan. Looking forward to a long future with NOVA AI.

This is truly the fastest way to create stunning videos.

What I was looking for for a long time!I missed the Happyscribe deal, so I used it by paying for some videos. When I saw that NovaAI offered the same thing, but better, I didn't hesitate for a second.

I love the ease of importing a video, and the generation of subtitles.

Being French, I had very little correction to do. In one click, my subtitles were translated into English, et voilà!

Not much to criticize: maybe the delay of the operations is a bit long, but it remains anecdotal.

Thank you for this deal, it will help me a lot!

@AlexSpirit - app sumo review

I uploaded a clear, English speaking video clip, and the subtitles were spot-on, with minor corrections needed.

Then I translated the English subtitles to Chinese, and was pleasantly surprised to see that it isn't just a literal word-by-word translation, but with correct sentence composition, since

Chinese structure is very different from English. The only glitch I found is that the Traditional Chinese translation is actually in Simplified Chinese. It's identical to the Simplified Chinese translation. I am sure it's an oversight and an easy fix for the developer.

The transcribing and translating of subtitles alone will save me so much time. I just need to upload the video and let Nova A.I. work in the cloud, while I move on to do other things. If you need subtitles, this is your tool!

@Adam2000 - app sumo review

I am sure many like me are wondering, I dont need another video tool. Thats what i thought too but could not resist taking it for a ride and i can say that its my all time favorite.

All the basic tools needed for video editing is there and it works like a charm, something like a desktop type smoothness. But that not that only its got tons of features and a solid AI working behind the scene like elevating your video cataloguing to another level and that too without you doing anything, all AI driven.

I mean thats wooow.....especially at this price point. And it transcribes and translates.....well, what can it not do. solid 5 tacos.for us UI UX and ease of use are most important, nova scores 10/10 in that.

We were using other online video tools but gradually they seems slow down on loading and rendering, hope nova will learn from those experiences and will make sure flowless fast result generation.

@Uni - app sumo review

For me, one of the most tedious tasks in video production (in a one-man-operation) is adding subtitles.

I have been unsuccessfully searching for a tool that can help me achieve this task with the least amount of headache while still achieving great accuracy - and I'm happy to say that with out a doubt, Nova AI has taken this headache away.

I think a lot more work is still needed for this tool to reach it's full potential, which to be fair, are just extra bells and whistles but important non the less; right now, the editor still looks a little too basic.

That being said, I don't really see this as an issue, because for my needs, this app has already met my expectations. So please, regardless of the extra features the devs are looking to implement, don't mess around too much with the excellent the auto subtitle generator.
