Vernier Video Physics App Reviews

Almost there

Great start; very handy and easy to implement in or out of the classroom.. WHAT IT NEEDS: *****Derive acceleration graphs from velocity graphs.... Easy programing fix **Export files directly to drop box, right now you have to email it out then import them into dropbox from your email, **Also export the data in an excel or csv file for other uses would be nice.. It would be nice to see: and perfect if *A little bit harder to understand mathematically but still easy to program, be able to not only rotate the origin for a tilted camera but be able to show the plane that is of interest incase you are filming something thats not directly perpendicular to the camera... Thanks a lot! Good start!

This is a great app

I am a physics teacher, and this app is amazing. The best way to show it in the classroom is with (surprise) verniers logger pro software. Record the video on the iphone and then send it to your computer. Then use logger pro on your computer and show it on the LCD. I am even able to avoid mac/pc issues when I use my schools pcs. The controls are a bit touchy when using the analysis tools on the iphone, but it just takes getting used to it.

Missing one thing

This is great, but I would like to see acceleration too. Or a table to go with the graphs so I can get more precise numbers to calculate the acceleration.

All work and all play ;)

Here are some suggestions: * enable users to easily save graphs--separate or combined--in PNG to camera roll. Screenshot just doesnt cut it. * include data table, too. * provide vector/Bezier curve for easy motion tracking. Eyeballing is OK right now but less accurate; plus, it would save a lot of time to use vector instead of manually dragging the crosshair * multiple analysis points Keep up the good work !

Very good, almost perfect!

This is very useful for me as an animation student, especially for tracking one of the animation principles: Arc. I am having fun doing this. For the most, I can see the timing and spacing even though is not accurate or detail. Thank you for making this app! I could give this 5 stars, if only: 1. Theres an option to use frames per second instead (fps) 2. The app can detect, how many frames per second the video was recorded. 3. Tap and slide option to forward the video every frame 4. I wish I can change the size of the dots or the tracker.

Needs curve fit

Recording and finding points works very well, but without the ability to curve fit you cannot do any analysis on the iPad. A linear fit at the very least is needed to use this in any sort of meaningful way on its own. If you need to use a computer, you might as well just use this as a video camera without the app.

Over a year since last update!

When this app first came out it had some interesting functionality, but more potential than performance. Despite many good recommendations for enhancement by other reviewers (ex. Acceleration vs. time) the app has stayed stagnant. Im beginning to wonder if this app was only released as bait to use logger pro since it has such limited functionality using iOS. Its almost a pedagogical crime to not take much better advantage of the incredible potential of this app. For shame Vernier.

Easy to use

I tried this app in class with my students today. I demod it quickly, then had them video a ball being tossed straight up and look at the graphs. I was amazed at how quickly they caught on and the quality of the graphs they got. It only took them about 10 minutes. Now that I know its pretty quick, we can analyze many different types of motion. It is limited by the quality of the video, faster things tend to get blurred. There is the ability to zoom in on objects moving slower to get a more accurate positioning of them at various time intervals. I found with slower moving objects, it was better to skip ahead an equal number of frames. I only wish it had the ability to find the slope of the graphs, maybe it does and I didnt find it.

Excellent app for first year physics lab

Used it this year with my first year physics classes. Shot a nerf gun, free throw, kicked a soccer ball etc. With a class set of iPads every student could do their own video and data analysis. In the past we had to find a digital video camera, take turns doing the video, download the video then do analysis. This turned a four hour lab into a two hour lab with each student able to do their own analysis. Highly recommended.

Good

This app looks good. I havent used it yet. But I think It is expensive.

Graphics

Very hard to control. Program locked into graph mode and I have wasted another hour on enriching apple corp.

No auto tracking, need more software to analyze

The ability to quickly get video and tap to analyze on the ipad is nice, but there are two key features that I would expect in a PC video analysis package that are not included here. You cannot easily export to a spreadsheet ( for an ipad app, exporting to numbers would make a lot of sense ) and additionally, the app does not include auto tracking capabilities, you must tap on every frame that you want to analyze.

Super Easy

Just tried it today on a video of a falling object. It works great. You tap to set points that track the object. Then it produces graphs of x,y position and time. I havent tried it in class yet but feel confident students will pick it up in under 10 minutes. I wish it could output to an excel or google docs spreadsheet. It can save a logger pro file to Dropbox or Google docs.

Add analysis tools to the app like linear regression!

Good app for any physics classroom but should be able to analyze on the iOS device or able to export to excel! Please add these features; not everyone has a logger pro license!

Incredibly useful, easy to pick up utility

Great for school, athletics, etc.

Awesome App

I am a physics teacher and love to use this app. It does a fantastic job at showing the motion of the object and then graphing the position vs time as well as velocity vs time. The use and manipulation of the app to plot points and set up your scale and origin is fantastic. My request (at to give it 5 stars) would be to allow you option to export the coordinate system with the video. Also, it wouldd be great if it would graph the acceleration vs time.

Great improvements

Ive used this app for years but the recent update is wonderful!! If only I could plot multiple sets of data (maybe each set in a different color). Example: tracking two objects in motion at the same time, to compare projectiles, etc

Amazing!

Automatic object tracking of objects is amazing. I no longer have to spend 10 minutes adding points to my videos. Plus it has experiment renaming! What more could you want?

Buggy but great when it works.

I bought this app as a high school teacher, mainly for tracking the parabolic path of projectiles. The app has a tendency to crash. Weird bug this week. I recorded a video on my iPhone 6+, sent it to my iPad Air 1 and the video became scrambled like a TV in the old days of antenna reception. Its great when it works.

Automation too buggy

Is there anyway to disable the automatic tracker and go back to manual input? I have found that automation tends to slip off objects pretty easily. I also think there is something to students locating the object and placing the dot themselves. Its easier For them to understand what the app is doing. I would love to have my old version back!!!
